    Lakes as sentinels of climate change2009Inngår i: Limnology and Oceanography, ISSN 0024-3590, E-ISSN 1939-5590, Vol. 54, nr 6(2), s. 2283-2297Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    While there is a general sense that lakes can act as sentinels of climate change, their efficacy has not been thoroughly analyzed. We identified the key response variables within a lake that act as indicators of the effects of climate change on both the lake and the catchment. These variables reflect a wide range of physical, chemical, and biological responses to climate. However, the efficacy of the different indicators is affected by regional response to climate change, characteristics of the catchment, and lake mixing regimes. Thus, particular indicators or combinations of indicators are more effective for different lake types and geographic regions. The extraction of climate signals can be further complicated by the influence of other environmental changes, such as eutrophication or acidification, and the equivalent reverse phenomena, in addition to other land-use influences. In many cases, however, confounding factors can be addressed through analytical tools such as detrending or filtering. Lakes are effective sentinels for climate change because they are sensitive to climate, respond rapidly to change, and integrate information about changes in the catchment.

    Long-term droughts may drive drier tropical forests towards increased functional, taxonomic and phylogenetic homogeneity2020Inngår i: Nature Communications, E-ISSN 2041-1723, Vol. 11, nr 1Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Tropical ecosystems adapted to high water availability may be highly impacted by climatic changes that increase soil and atmospheric moisture deficits. Many tropical regions are experiencing significant changes in climatic conditions, which may induce strong shifts in taxonomic, functional and phylogenetic diversity of forest communities. However, it remains unclear if and to what extent tropical forests are shifting in these facets of diversity along climatic gradients in response to climate change. Here, we show that changes in climate affected all three facets of diversity in West Africa in recent decades. Taxonomic and functional diversity increased in wetter forests but tended to decrease in forests with drier climate. Phylogenetic diversity showed a large decrease along a wet-dry climatic gradient. Notably, we find that all three facets of diversity tended to be higher in wetter forests. Drier forests showed functional, taxonomic and phylogenetic homogenization. Understanding how different facets of diversity respond to a changing environment across climatic gradients is essential for effective long-term conservation of tropical forest ecosystems. Different aspects of biodiversity may not necessarily converge in their response to climate change. Here, the authors investigate 25-year shifts in taxonomic, functional and phylogenetic diversity of tropical forests along a spatial climate gradient in West Africa, showing that drier forests are less stable than wetter forests.

    Abstract [en]

    Greenhouse gas emissions and land subsidence on four cultivated peat soils (Martebo, Örke, Kälkestad, Lidhult) have been investigated by measuring emissions of carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) in field and lab. Greenhouse emitted gas (mg/h) from undisturbed soil cores was measured in lab. Measurements were performed at four different drainage depths. Soil cores were also kept incubated at constant drainage depth and emitted gas was measured with two-week intervals at three measurement occasions. Field measurements of CO2 emissions (mg/h/m2) were also performed. In addition to gas emissions, irrigation of soil cores has been carried out to investigate the risk of leaching of copper (Cu), phosphorus (P), nitrogen (N) and dissolved organic matter (DOC) during rewetting, and whether turbidity can be used as a measurement of DOC.

    Land surveying with GPS was done on three of the peat soils. This was to investigate how land subsidence can be related to CO2 emissions. On one of the sites different land surveying methods were used to assess their suitability for tracking land subsidence in peat soils. 30 year land surveying data from the sites have also been compiled and analyzed.

    The peat soils are part of a long-term experiment that was laid out in 1986. On each site one field was fertilized with copper and one was kept untreated as comparision. The purpose of the copper fertilizer was to reduce the activity of microorganisms. By doing so the degradation of soil organic matter could be reduced, thereby reducing the land subsidence.

    The results show that the ground surface at all four sites has subsided, but no difference is observed for copper-fertilized fields compared to untreated. Neither could an effect on CO2 emissions from copper fertilization be noted. The greatest land subsidence was observed for Martebo and the least for Kälkestad. By using data from the most recent time period the greatest subsidence was instead observed for Örke. This is consistent with Örke having the greatest CO2 emissions. CO2 emissions alone could not explain land subsidence.

    The results also show that emitted N2O was higher for nutrient-rich soils with the peak directly after saturation. CH4 was at its lowest initially, but then increased and emitted CH4 was greatest for the soils where easily biodegradable organic matter was available. Turbidity alone could not explain the DOC content in leachate from the irrigated soil cores.

    Conclusions drawn were that copper fertilization had no effect on land subsidence and CO2 emissions in this case. Copper did however still leach from the soils 30 years after addition. Emissions of CO2, N2O and CH4 varies greatly between the different soils. To be able to obtain reliable levels of greenhouse gas emissions from peat soils in climate models, more research is needed on how different peat soils react to water and nutrient content.

    It is important to have long time series when measuring land subsidence. Using the same measurement equipment will give better results. GPS for land surveying of peatland can be recommended if the results can be related to a fix point.

    Climate Change-Induced Riverine Floods: A Case Study of the Lower Indus River, Sindh, Pakistan.2024Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    The Earth's climate has been consistently warming since the mid-eighteenth century, largely due to human activities, particularly the industrial revolution. This has led to a significant increase in greenhouse gas (GHG) emissions, a major driver of climate change. While the impacts of climate change are global, they are not evenly distributed, and developing countries, including Pakistan, bear a disproportionate burden. Despite contributing only 0.7% of global GHG emissions, Pakistan ranks as the sixth most vulnerable country to the impacts of climate change.

    This thesis focuses on analyzing the effects of climate change on riverine floods in the lower Indus River, Sindh, Pakistan, during the period from 2010 to 2013. The study delves into the consequences of floods on various aspects of communities, including agriculture, health, displacement, social structures, and livelihoods. Additionally, it explores adaptive measures required by humanitarian organizations and governments to mitigate these risks.

    In the theoretical framework, the vulnerability theory is employed to enhance our understanding of vulnerabilities and impacts associated with climate change-induced floods. The Sendai Framework for Disaster Risk Reduction is utilized to better comprehend disasters, build resilience, and facilitate adaptation strategies.

    Recognizing that the window for mitigating the effects of climate change has closed, the thesis emphasizes the urgency of adaptation. It contends that vulnerabilities associated with climate change-induced floods can be significantly reduced, and certain effects can be harnessed for beneficial purposes through proper adaptation strategies. For instance, the flooding of the lower Indus River delta during the summer months (July to September) creates an opportunity to store water for use during the remaining nine months, thus mitigating droughts and water scarcity.

    Archaeal community changes in Lateglacial lake sediments: Evidence from ancient DNA2018Inngår i: Quaternary Science Reviews, ISSN 0277-3791, E-ISSN 1873-457X, Vol. 181, s. 19-29Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The Lateglacial/early Holocene sediments from the ancient lake at Hasseldala Port, southern Sweden provide an important archive for the environmental and climatic shifts at the end of the last ice age and the transition into the present Interglacial. The existing multi-proxy data set highlights the complex interplay of physical and ecological changes in response to climatic shifts and lake status changes. Yet, it remains unclear how microorganisms, such as Archaea, which do not leave microscopic features in the sedimentary record, were affected by these climatic shifts. Here we present the metagenomic data set of Hasseldala Port with a special focus on the abundance and biodiversity of Archaea. This allows reconstructing for the first time the temporal succession of major Archaea groups between 13.9 and 10.8 ka BP by using ancient environmental DNA metagenomics and fossil archaeal cell membrane lipids. We then evaluate to which extent these findings reflect physical changes of the lake system, due to changes in lake-water summer temperature and seasonal lake-ice cover. We show that variations in archaeal composition and diversity were related to a variety of factors (e.g., changes in lake water temperature, duration of lake ice cover, rapid sediment infilling), which influenced bottom water conditions and the sediment-water interface. Methanogenic Archaea dominated during the Allerod and Younger Dryas pollen zones, when the ancient lake was likely stratified and anoxic for large parts of the year. The increase in archaeal diversity at the Younger Dryas/Holocene transition is explained by sediment infilling and formation of a mire/peatbog. (C) 2017 Elsevier Ltd. All rights reserved.

    Global Warming Induced by Oceanic Anoxic Event 1a Had a Pronounced Impact on the Early Cretaceous Terrestrial Vegetation of Southern Sweden2022Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    The Mesozoic is punctuated by several rapid global warming events that are marked by the worldwide deposition of organic-rich marine sediments. These events, known as oceanic anoxic events (OAEs), are characterised by intervals where the worldwide carbon cycle suffers a disruption due to major palaeoceanographic and climatic shifts, leading to anoxic marine environments and the creation of black shales. For this study, the Oceanic Anoxic Event 1a (OAE 1a), which occurred during the Early Cretaceous Aptian age (~120 Ma) was analysed. It was likely triggered by the Greater Ontong Java underwater volcanic event and is associated with major changes in marine environments and ecosystems, including nekton and plankton turnover, and sea water composition changes. The impact of this event on terrestrial land-based ecosystems is, however, less well understood. Here I document well preserved and diverse spore-pollen assemblages spanning OAE 1a from southern Sweden by examining the Höllviken I core.

    Before the OAE, palynofloras are dominated by conifers, suggestive of a relatively mild and dry coastal environment. At the onset of the OAE a fern spike occurs, where there is a shift to early successional stage vegetation. Gymnosperm diversity and abundance sharply decrease, and the palynofloral assemblages become dominated by ferns, indicating a shift to warm and wet conditions. Gymnosperms gradually recover thereafter, but the formerly abundant conifer pollen Classopollis does not recover and remains rare. Dinoflagellate cysts and microforaminiferal test linings increase in abundance after OAE 1a, suggesting a higher degree of marine influence.

    These findings show that OAE 1a had a substantial impact on the composition and diversity of high latitude terrestrial vegetation and marine plankton communities.

    Risker vid översvämning och åtgärdsförslag för MSB:s skola i Revinge2021Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    På skolan i Revinge utbildar Myndigheten för samhällsskydd och beredskap (MSB) personer inom områdena skydd mot olyckor och krisberedskap. Vid ett flertal tillfällen har Kävlingeån översvämmat skolområdet vilket resulterat i att verksamheten blivit stillastående i flera veckor. Grundvattennivån ligger nära markytan på skolområdet och platsen är därför extra känslig för översvämningar både från ån och extrem nederbörd.

    För att kunna minimera konsekvenserna vid en översvämning identifierades olika objekt, byggnader och områden, som i rapporten är benämnda som skyddsobjekt, som drabbas mest vid översvämning. För att ta hänsyn till att framtida väderförhållanden kan bli mer extrema undersöktes två klimatanpassade scenarier, höga flöden från ån och extrem nederbörd. Olika åtgärder mot översvämningar som potentiellt kan passa skolområdet togs fram och viktades utefter kostnader, lagar och skyddskapacitet.

    Skyddsobjekten som togs fram är skolans övningytor, kontorsbyggnader, hus med källare, spillvattenbrunnar, områden som kan sprida miljöfarliga ämnen, elskåp samt fordonshall/förråd. Skyddsobjekten viktades utefter översvämningskonsekvensernas direkta kostnader, hinder för utbildning samt fara för människor och natur, i relation till hur sannolikt det är att objekten blir översvämmade. Övningsytor, spillvattenbrunnar och områden som kan sprida miljöfarliga ämnen fick högsta prioritet.

    De åtgärder mot översvämning som undersöktes var gröna tak, regnmagasin, regnbäddar, träd, kontrollerad översvämningsyta och permanent vall. De fyra förstnämnda bedömdes billiga och lagligt sett icke komplicerade i relation till permanent vall och kontrollerad översvämningsyta. En summering av vilka skyddsobjekt varje åtgärd skyddar lades till. En effektivitetsfaktor togs fram i relation till vilka scenarier åtgärderna verkar mot och i vilken grad de kan motverka ett scenario på egen hand. Detta gav värderingen, från högst till lägst, permanent vall, träd, översvämningsyta, regnmagasin, regnbäddar och gröna tak.

    Som ytterligare åtgärder rekommenderas det att utesluta användning av källare helt och bestämmelser kring nybyggnation bör tas i relation till var det finns störst risk för översvämning på området. Ett förslag till MSB finns om att ta kontakt med Kävlingeå-projektet som arbetar med att utöka andelen våtmarker utmed Kävlingeån, där ett av målen för projektet är att motverka översvämningar. Arbetet drivs av Kävlingeåns Vattenråd, vilka också kan ha mer information kring hur regleringen av Vombsjön kan påverka risken för översvämning på skolområdet.

    A factor of two: how the mitigation plans of ‘climate progressive nations’ fall far short of Paris-compliant pathways2020Inngår i: Climate Policy, ISSN 1469-3062, E-ISSN 1752-7457, Vol. 20, nr 10, s. 1290-1304Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The Paris Agreement establishes an international covenant to reduce emissions in line with holding the increase in temperature to 'well below 2 degrees C horizontal ellipsis and to pursue horizontal ellipsis 1.5 degrees C.' Global modelling studies have repeatedly concluded that such commitments can be delivered through technocratic adjustments to contemporary society, principally price mechanisms driving technical change. However, as emissions have continued to rise, so these models have come to increasingly rely on the extensive deployment of highly speculative negative emissions technologies (NETs). Moreover, in determining the mitigation challenges for industrialized nations, scant regard is paid to the language and spirit of equity enshrined in the Paris Agreement. If, instead, the mitigation agenda of 'developed country Parties' is determined without reliance on planetary scale NETs and with genuine regard for equity and 'common but differentiated responsibilities and respective capabilities', the necessary rates of mitigation increase markedly. This is evident even when considering the UK and Sweden, two nations at the forefront of developing 'progressive' climate change legislation and with clear emissions pathways and/or quantitative carbon budgets. In both cases, the carbon budgets underpinning mitigation policy are halved, the immediate mitigation rate is increased to over 10% per annum, and the time to deliver a fully decarbonized energy system is brought forward to 2035-40. Such a challenging mitigation agenda implies profound changes to many facets of industrialized economies. This conclusion is not drawn from political ideology, but rather is a direct consequence of the international community's obligations under the Paris Agreement and the small and rapidly dwindling global carbon budget. Key Policy Insights Without a belief in the successful deployment of planetary scale negative emissions technologies, double-digit annual mitigation rates are required of developed countries, from 2020, if they are to align their policies with the Paris Agreement's temperature commitments and principles of equity. Paris-compliant carbon budgets for developed countries imply full decarbonization of energy by 2035-40, necessitating a scale of change in physical infrastructure reminiscent of the post-Second World War Marshall Plan. This brings issues of values, measures of prosperity and socio-economic inequality to the fore. The stringency of Paris-compliant pathways severely limits the opportunity for inter-sectoral emissions trading. Consequently aviation, as with all sectors, will need to identify policies to reduce emissions to zero, directly or through the use of zero carbon fuels. The UK and Swedish governments' emissions pathways imply a carbon budget of at least a factor of two greater than their fair contribution to delivering on the Paris Agreement's 1.5-2 degrees C commitment.

    A Guide for a Fair Implementation of the Paris Agreement within Swedish Municipalities and Regional Governments: Part II of the Carbon Budget Reports Submitted to Swedish Local Governing Bodies in the 2018 Project "Koldioxidbudgetar 2020-2040"2018Rapport (Annet vitenskapelig)
    Abstract [en]

    Since 2015, Uppsala University has hosted the Zennström Visiting Professorship in Climate Change Leadership, part of a 10-year series of visiting professorships (2015-2025) funded by Zennström Philanthropies. The ambition of the initiative is to tackle some of the largest challenges climate change poses to humanity, by developing new solutions and enabling transformational change at the intersection of science, politics and innovation. Kevin Anderson, Professor of Energy and Climate Change at the University of Manchester and Deputy Director at the Tyndall Centre for Climate Change Research was the second holder of this professorship, taking up the positionin August 2016. He has pioneered research on carbon budgets and pathways to acceptable mitigation levels with a focus on Sweden and the UK (see Anderson et al., 2017 and Kuriakose et al., 2018). In 2017, Järfälla municipality contacted the Climate Change Leadership (CCL) Node at Uppsala University seeking a carbon budget for their municipality which was published later that year (Anderson et al., 2017). When this report was completed, more municipalities contacted CCL to request similar carbon budget calculations. The great interest resulted in the project, “Koldioxidbudgetar 2020-2040” (Carbon budgets 2020-2040) starting in2018 in collaboration with Ramboll. This ongoing project is characterised by a high level of collaboration and knowledge sharing between municipalities (kommuner), regional governments (län) and the Climate Change Leadership Node in order to produce reports that meet the needs and expectations of participating governing bodies. This report is part II of the project. Part I consists of individual carbon budget reports submitted to participating Swedish municipalities and regional governments.

    Carbon budget and pathways to a fossil-free future in Järfälla Municipality2017Rapport (Annet vitenskapelig)
    Abstract [en]

    In 2015, the global community committed to hold global average temperature increase to “well below 2°C above preindustrial levels and pursuing efforts to limit the temperature increase to 1.5°C.”. While nations showed clear commitment to the Paris Agreement’s temperature goals, what would those pledges entail for cities desiring to make a fair contribution to addressing climate change? This report is the result of research that the Centre for Sustainable Development (CEMUS) at Uppsala University and SLU conducted on behalf of Järfälla Municipality. The report describes the calculation of a carbon budget for Sweden, followed by a calculation of Järfälla Municipality's carbon budget. The report concludes with a chapter describing emissions reductions pathways (and possible corresponding measures) for Järfälla Municipality if they are to make their fair contribution to the Paris Agreement and pave the way for the transition to a fossil-free future.

    Synoptic Variability of Extreme Snowfall in the St. Elias Mountains, Yukon, Canada2015Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    Glaciers of southwestern Yukon (Canada) and southeastern Alaska (USA) are presently experiencing high rates of annual mass loss. These high melt rates have mainly been investigated with respect to regional temperature trends, but comparatively little is known about how climate variations regulate snow accumulation on these glaciers. This study examines the synoptic weather patterns and air flow trajectories associated with extreme snowfall events in the central St. Elias Mountains (Yukon). The analyses are based on data retrieved from an automated weather station (AWS) between 2003 and 2012, which provide the longest continuous records of surface meteorological data ever obtained from this remote region.

    The AWS data reveal that 47 extreme snowfall events (> 27 cm per 12 hours) occurred during this period, of which 79 % took place during the cold season months. Air flow trajectories associated with these events indicate that a vast majority had their origin in the North Pacific south of 50°N. Less frequent were air masses with a source in the Aleutian Arc/Bering Sea region and the Gulf of Alaska, and in a few rare cases precipitating air was traced to continental source regions in Western Canada and Alaska. Composite maps of sea-level pressure and upper-level winds associated with extreme snowfall events revealed a frequent synoptic pattern with a low-pressure area centered over the Kenai Peninsula (Alaska), which drives strong southerly winds over the Gulf of Alaska towards the St. Elias Mountains. This pattern is consistent with AWS data wind recordings during snow storms. The most typical synoptic configurations of the North Pacific low-pressure area during extreme snowfall events are either elongated, split, or single-centered, and these situations represent possible seasonal analogues for the different states of the Aleutian Low in the subarctic North Pacific. However, neither the geographical position or intensity of negative sea-level pressure anomalies, nor surface pressure gradients associated with extreme snowfall events are good predictors of the actual snowfall SWE amounts recorded in the central St. Elias Mountains. Estimated snowfall and total precipitation gradients with altitude were confirmed to be much steeper (by up to ~30 %) on the continental side (Yukon), than on the coastal side (Alaska) of the St. Elias Mountains, reflecting the strong orographic division between the continental and coastal marine climatic regimes. Finally, patterns of 500-mb geopotential height anomalies associated with extreme snowfall events at Divide were compared with those associated with unusually high accumulation years in an ice core from the nearby Eclipse Icefield. Results confirm previous findings that associate high snow accumulation winters in this region with the presence of a strong dipole pressure structure between western North America and the Aleutian Low region, a structure which resembles the positive phase of the Pacific North American atmospheric circulation pattern.

    Reconstructing Past Climate by Using XRF and Loss of Ignition on Loess from Adventdalen, Svalbard: Rekonstruktion av tidigare klimat genom attanvända XRF analys och antändningsförlust på lössavlagringar från Adventdalen, Svalbard2023Independent thesis Basic level (degree of Bachelor), 180 hpOppgave
    Abstract [en]

    By analyzing the texture, composition and chemical composition of loess soils, the reconstruction ofpast climate regimes is enabled, which can improve our understanding of current and future climatechange. Properties such as grain size and composition, mineralogy, organic matter and chemicalcomposition can provide information about which environmental factors were present during thedeposition of the sediment, which can lead to a detailed picture of the climate history of a site. Researchon loess soils in the polar regions is particularly valuable because its climate is most rapidly affected byglobal warming. The purpose of the study has therefore been to understand and convey new data to thepaleo-climate around the Arctic by examining and analyzing loess soil sequences at a depth between 0and 175 cm from Adventdalen, Svalbard. In this study, the samples are analyzed with XRF (X-rayfluorescence) and LOI (Loss of Ignition). XRF is used to find out the mineral composition of the soils,while LOI is used to find out the percentage of organic content and carbonates.Data from the oldest part of the stratigraphic section indicate a sharp increase in weathering, from acooler period about 3000 years ago to a warming until about 2000 years ago. Weathering intensitiesderived from Na/Al-based indices show relatively frequent oscillations throughout the section, but arestable from about 100-70 cm. The high and stable weathering values during this period can probably beattributed to the Medieval Warm Period, which coincides with the relative dating of the site. Datacollected from the LOI shows a clear trend throughout the section, with a decrease in organic matterfrom 3000 BC to the present.

    State of the Climate in 20162017Inngår i: Bulletin of The American Meteorological Society - (BAMS), ISSN 0003-0007, E-ISSN 1520-0477, Vol. 98, nr 8, s. S1-S280Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    In 2016, the dominant greenhouse gases released into Earth's atmosphere-carbon dioxide, methane, and nitrous oxide-continued to increase and reach new record highs. The 3.5 +/- 0.1 ppm rise in global annual mean carbon dioxide from 2015 to 2016 was the largest annual increase observed in the 58-year measurement record. The annual global average carbon dioxide concentration at Earth's surface surpassed 400 ppm (402.9 +/- 0.1 ppm) for the first time in the modern atmospheric measurement record and in ice core records dating back as far as 800000 years. One of the strongest El Nino events since at least 1950 dissipated in spring, and a weak La Nina evolved later in the year. Owing at least in part to the combination of El Nino conditions early in the year and a long-term upward trend, Earth's surface observed record warmth for a third consecutive year, albeit by a much slimmer margin than by which that record was set in 2015. Above Earth's surface, the annual lower troposphere temperature was record high according to all datasets analyzed, while the lower stratospheric temperature was record low according to most of the in situ and satellite datasets. Several countries, including Mexico and India, reported record high annual temperatures while many others observed near-record highs. A week-long heat wave at the end of April over the northern and eastern Indian peninsula, with temperatures surpassing 44 degrees C, contributed to a water crisis for 330 million people and to 300 fatalities. In the Arctic the 2016 land surface temperature was 2.0 degrees C above the 1981-2010 average, breaking the previous record of 2007, 2011, and 2015 by 0.8 degrees C, representing a 3.5 degrees C increase since the record began in 1900. The increasing temperatures have led to decreasing Arctic sea ice extent and thickness. On 24 March, the sea ice extent at the end of the growth season saw its lowest maximum in the 37-year satellite record, tying with 2015 at 7.2% below the 1981-2010 average. The September 2016 Arctic sea ice minimum extent tied with 2007 for the second lowest value on record, 33% lower than the 1981-2010 average. Arctic sea ice cover remains relatively young and thin, making it vulnerable to continued extensive melt. The mass of the Greenland Ice Sheet, which has the capacity to contribute similar to 7 m to sea level rise, reached a record low value. The onset of its surface melt was the second earliest, after 2012, in the 37-year satellite record. Sea surface temperature was record high at the global scale, surpassing the previous record of 2015 by about 0.01 degrees C. The global sea surface temperature trend for the 21st century-to-date of +0.162 degrees C decade(-1) is much higher than the longer term 1950-2016 trend of +0.100 degrees C decade(-1). Global annual mean sea level also reached a new record high, marking the sixth consecutive year of increase. Global annual ocean heat content saw a slight drop compared to the record high in 2015. Alpine glacier retreat continued around the globe, and preliminary data indicate that 2016 is the 37th consecutive year of negative annual mass balance. Across the Northern Hemisphere, snow cover for each month from February to June was among its four least extensive in the 47-year satellite record. Continuing a pattern below the surface, record high temperatures at 20-m depth were measured at all permafrost observatories on the North Slope of Alaska and at the Canadian observatory on northernmost Ellesmere Island. In the Antarctic, record low monthly surface pressures were broken at many stations, with the southern annular mode setting record high index values in March and June. Monthly high surface pressure records for August and November were set at several stations. During this period, record low daily and monthly sea ice extents were observed, with the November mean sea ice extent more than 5 standard deviations below the 1981-2010 average. These record low sea ice values contrast sharply with the record high values observed during 2012-14. Over the region, springtime Antarctic stratospheric ozone depletion was less severe relative to the 1991-2006 average, but ozone levels were still low compared to pre-1990 levels. Closer to the equator, 93 named tropical storms were observed during 2016, above the 1981-2010 average of 82, but fewer than the 101 storms recorded in 2015. Three basins-the North Atlantic, and eastern and western North Pacific-experienced above-normal activity in 2016. The Australian basin recorded its least active season since the beginning of the satellite era in 1970. Overall, four tropical cyclones reached the Saffir-Simpson category 5 intensity level. The strong El Nino at the beginning of the year that transitioned to a weak La Nina contributed to enhanced precipitation variability around the world. Wet conditions were observed throughout the year across southern South America, causing repeated heavy flooding in Argentina, Paraguay, and Uruguay. Wetter-than-usual conditions were also observed for eastern Europe and central Asia, alleviating the drought conditions of 2014 and 2015 in southern Russia. In the United States, California had its first wetter-than-average year since 2012, after being plagued by drought for several years. Even so, the area covered by drought in 2016 at the global scale was among the largest in the post-1950 record. For each month, at least 12% of land surfaces experienced severe drought conditions or worse, the longest such stretch in the record. In northeastern Brazil, drought conditions were observed for the fifth consecutive year, making this the longest drought on record in the region. Dry conditions were also observed in western Bolivia and Peru; it was Bolivia's worst drought in the past 25 years. In May, with abnormally warm and dry conditions already prevailing over western Canada for about a year, the human-induced Fort McMurray wildfire burned nearly 590000 hectares and became the costliest disaster in Canadian history, with $3 billion (U.S. dollars) in insured losses.

    Techno-economic assessment of energy and environmental impact of waste-to-energy electricity generation2023Inngår i: Energy Reports, E-ISSN 2352-4847, Vol. 9, nr Suppl 1, s. 1087-1097Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This study explored cumulative 127.5MW waste to energy (WtE) potential in five populous cities of Pakistan based on local waste characterization profiles and global standards. The 50MW WtE plant in Lahore using National electricity regulator codes and practices resulted in an attractive Levelized cost of electricity (LCOE) of US¢ 7.86/kWh over 25 years with a $151.5 million investment cost. The net savings to Lahore Waste Management Company can be $103.4 and $137.7 million respectively with and without tipping fees on account of waste disposal cost, bricks revenue using bottom ash, and waste fee. The project developers can get net savings of $16.9 and $51.5 million respectively with and without tipping fees other than LCOE. Furthermore, the greenhouse gas emissions of 216.6 million tons of CO2eq can be saved throughout plant life against 279 GWh/year energy generation, in terms of grid emission factor and current methane release into the atmosphere from the dumping site.

    The SISAL database: a global resource to document oxygen and carbon isotope records from speleothems2018Inngår i: Earth System Science Data, ISSN 1866-3508, E-ISSN 1866-3516, Vol. 10, nr 3, s. 1687-1713Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Stable isotope records from speleothems provide information on past climate changes, most particularly information that can be used to reconstruct past changes in precipitation and atmospheric circulation. These records are increasingly being used to provide "out-of-sample" evaluations of isotope-enabled climate models. SISAL (Speleothem Isotope Synthesis and Analysis) is an international working group of the Past Global Changes (PAGES) project. The working group aims to provide a comprehensive compilation of speleothem isotope records for climate reconstruction and model evaluation. The SISAL database contains data for individual speleothems, grouped by cave system. Stable isotopes of oxygen and carbon (delta O-18, delta C-13) measurements are referenced by distance from the top or bottom of the speleothem. Additional tables provide information on dating, including information on the dates used to construct the original age model and sufficient information to assess the quality of each data set and to erect a standardized chronology across different speleothems. The metadata table provides location information, information on the full range of measurements carried out on each speleothem and information on the cave system that is relevant to the interpretation of the records, as well as citations for both publications and archived data.

    Modelling impact climate-related change on the thermal responses of lakes2023Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    In response to climate-related changes, lakes worldwide have experienced warmer surface water temperatures, shorter ice cover periods and changes in lake stratification. As these aspects of lake dynamics exert substantial control over nutrient availability, oxygenation and biogeochemical cycling, predicting changes in lake water temperature and stratification dynamics can improve our understanding of the consequences of warming on lake ecosystems. This thesis investigates the long-term and short-term (extreme event) effects of climate change on lake thermal dynamics using 1D hydrodynamic lake models.

    Long-term lake water temperature simulations showed that water temperatures and thermal stratification metrics were projected to clearly shift toward lake thermal conditions that are consistent with a warmer climate at the end of the 21st century, i.e. warmer surface and bottom temperatures and a stronger and longer duration of summer thermal stratification as a result of an earlier onset of stratification and later fall overturn. The simulated lake thermal structure was controlled by energy exchange between the lake surface and the atmosphere (surface heat fluxes) and wind stress. The individual surface heat flux components were projected to change substantially under future climate scenarios. However, the combined changes showed compensating effects, leading to a small overall change in total surface heat flux, that was still sufficient to lead to important changes in whole-lake temperature. On a seasonal scale, spring heating and autumnal cooling were projected to decrease, while only small changes were projected in winter and summer. An extended analysis during summer using 47 lakes showed that while all lakes gained heat during summer under all scenarios, differences in the amount of heat gained during historical and future conditions were small. Additionally, hydrodynamic lake models performed well in reproducing the magnitude and direction of changes in lake temperature and stratification metrics during storms and heatwaves. However, the lake model performance decreased in accuracy compared to non-extreme condition, which should be taken into account. 

    1D hydrodynamic lake models have been shown to be powerful tools to predict long-term and short-term climate-related changes in lake thermal dynamics, making an in-depth analysis of the surface heat fluxes possible.

    Abstract [en]

    This paper, as a part of the Inter-Sectoral Impact Model Intercomparison Project (ISIMIP2b), assesses the impacts of different levels of global warming on the thermal structure of Lake Erken (Sweden). The General Ocean Turbulence Model (GOTM) one-dimensional hydrodynamic model was used to simulate water temperature when using ISIMIP2b bias-corrected climate model projections as input. These projections have a daily time step, while lake model simulations are often forced at hourly or shorter time steps. Therefore, it was necessary to first test the ability of GOTM to simulate Lake Erken water temperature using daily vs hourly meteorological forcing data. In order to do this, three data sets were used to force the model as follows: (1) hourly measured data, (2) daily average data derived from the first data set, and (3) synthetic hourly data created from the daily data set using generalised regression artificial neural network methods. This last data set is developed using a method that could also be applied to the daily time step ISIMIP scenarios to obtain hourly model input if needed. The lake model was shown to accurately simulate Lake Erken water temperature when forced with either daily or synthetic hourly data. Long-term simulations forced with daily or synthetic hourly meteorological data suggest that by the late 21st century the lake will undergo clear changes in thermal structure. For the representative concentration pathway (RCP) scenario, namely RCP2.6, surface water temperature was projected to increase by 1.79 and 1.36 C when the lake model was forced at daily and hourly resolutions respectively, and for RCP6.0 these increases were projected to be 3.08 and 2.31 C. Changes in lake stability were projected to increase, and the stratification duration was projected to be longer by 13 and 11 d under RCP2.6 scenario and 22 and 18 d under RCP6.0 scenario for daily and hourly resolutions. Model changes in thermal indices were very similar when using either the daily or synthetic hourly forcing, suggesting that the original ISIMIP climate model projections at a daily time step can be sufficient for the purpose of simulating lake water temperature.

    Abstract [en]

    Turbulent and radiative energy exchanges between lakes and the atmosphere play an importantrole in determining the process of lake-mixing and stratification, including how lakes respond to climate andto climate change. Here we used a one-dimensional hydrodynamic lake model to assess seasonal impacts ofclimate change on individual surface heat flux components in Lough Feeagh, Ireland, a deep, monomictic lake.We drove the lake model with an ensemble of outputs from four climate models under three future greenhousegas scenarios from 1976 to 2099. In these experiments, the results showed significant increases in the radiativebudget that were largely counteracted by significant increases in the turbulent fluxes. The combined change inthe individual surface heat fluxes led to a change in the total surface heat flux that was small, but sufficient tolead to significant changes in the volume-weighted average lake temperature. The largest projected changes intotal surface heat fluxes were in spring and autumn. Both spring heating and autumnal cooling significantlydecreased under future climate conditions, while changes to total surface heat fluxes in winter and summerwere an order of magnitude lower. This led to counter-intuitive results that, in a warming world, there wouldbe less heat not more entering Lough Feeagh during the springtime, and little change in net heating over thesummer or winter compared to natural climate conditions, projected increases in the volume-weighted averagelake temperature were found to be largely due to reduced heat loss during autumn.

    Abstract [en]

    Warming surface water temperature is the most direct consequence of climate change in lakes and therefore, predicting the heat exchange at the air-water interface is important to understand how atmospheric forcing will affect lake temperature and thermal structure. Here, we forced a one-dimensional hydrodynamic lake model with outputs from four different climate models under three future greenhouse gas emission scenarios from 1976 to 2099. To investigate the changes in summer (June to August or December to February in the northern or southern hemisphere, respectively) net surface heat flux and the individual flux components for 47 lakes with varying in size and geographic location were analysed. The results show that in the most extreme case (RCP 8.5) summer lake surface temperature is projected to increase by 4.72±0.70 °C by the end of the 21st century, due to increasing absorption of solar radiation (17.40±8.81 W m-2) and of long-wave radiation (33.01±5.44 W m-2). The increased lake surface temperature, also lead to higher heat losses to the atmosphere by outgoing long-wave radiation (27.54±4.07 W m-2) and by latent heat flux (25.10±7.37 W m-2), while a lower heat loss by sensible heat flux is projected (-3.20±1.94 W m-2). Altogether, the net heat balance and thus the accumulation of heat in the lakes over summer remains almost unchanged. However, a shift in the contributions of the individuals heat fluxes is projected, with the latent heat flux gaining relative importance.

    Abstract [en]

    Numerical lake models are useful tools to study hydrodynamics in lakes, and are increasingly applied to extreme weather events. However, little is known about the accuracy of such models during these short-term events. We used high-frequency data from three lakes to test the performance of three one-dimensional (1D) hydrodynamic models (Simstrat, GOTM, GLM) during storms and heatwaves. Models reproduced the overall direction and magnitude of changes during the extreme events, with accurate timing and little bias. Changes in volume-averaged and surface temperatures and Schmidt stability were simulated more accurately than changes in bottom temperature, maximum buoyancy frequency, or mixed layer depth. However, in most cases the model error was higher (30-100%) during extreme events compared to reference periods. As a consequence, while 1D lake models can be used to study effects of extreme weather events, the increased uncertainty in the simulations should be taken into account when interpreting results.

    GLOBAL WARMING WILL CHANGE THE THERMAL STRUCTURE OF LOUGH FEEAGH, A SENTINEL LAKE IN THE IRISH LANDSCAPE, BY THE END OF THE TWENTY-FIRST CENTURY2023Inngår i: Biology and Environment (Dublin), ISSN 0791-7945, E-ISSN 2009-003X, Vol. 123B, nr 3, s. 147-165Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Recent developments in impact modelling of global warming on lakes have resulted in a greater understanding of how these vital ecosystems are likely to respond. However, there has been little quantitative analysis of this in an Irish context, despite the importance of lakes in the island's landscape. Here, we explore the impact of global warming on the hydrodynamics and thermal structure of a sentinel Irish lake under future climate scenarios. A 1D lake model, Simstrat, was calibrated and validated using water temperature data collected from Lough Feeagh, a site of long-term ecological research in the west of Ireland. Once validated, the model was then driven by daily climate model projections to generate informative thermal metrics for the time period of 2006-2099. Despite the moderating influence of the Atlantic, projections indicate that global warming will have a marked effect on the thermal structure of Feeagh, with surface water temperatures set to warm by 0.75 degrees C under a more stringent mitigation pathway (RCP 2.6) and 2.42 degrees C under a non-mitigation pathway (RCP 8.5).While warming was projected to be greatest in summer in the epilimnion, winter warming was greater than in other seasons in the hypolimnion. Stratification is projected to become more stable and earlier, and the growing season to be longer by 11 to 47 days, depending on mitigation pathways. Future studies could use a similar modelling workflow to investigate the possible implications of global warming on other Irish lakes, particularly those of specific societal importance or those of conservation interest.

    Analysis of summer heat budget of lakes under a changing climate across a geographic gradientManuskript (preprint) (Annet vitenskapelig)
    Abstract [en]

    Warming surface water temperature is the most direct consequence of climate change in lakes and therefore, predicting the heat exchange at the air-water interface is important to understand how atmospheric forcing will affect lake temperature and thermal structure. Here, we forced a one-dimensional hydrodynamic lake model with outputs from four different climate models under three future greenhouse gas emission scenarios from 1976 to 2099. To investigate the changes in summer (June to August or December to February in the northern or southern hemisphere, respectively) net surface heat flux and the individual flux components for 47 lakes with varying in size and geographic location were analysed. The results show that in the most extreme case (RCP 8.5) summer lake surface temperature is projected to increase by 4.72±0.70 °C by the end of the 21st century, due to increasing absorption of solar radiation (17.40±8.81 W m-2) and of long-wave radiation (33.01±5.44 W m-2). The increased lake surface temperature, also lead to higher heat losses to the atmosphere by outgoing long-wave radiation (27.54±4.07 W m-2) and by latent heat flux (25.10±7.37 W m-2), while a lower heat loss by sensible heat flux is projected (-3.20±1.94 W m-2). Altogether, the net heat balance and thus the accumulation of heat in the lakes over summer remains almost unchanged. However, a shift in the contributions of the individuals heat fluxes is projected, with the latent heat flux gaining relative importance.

    Wood Anatomy of Douglas-Fir in Eastern Arizona and Its Relationship With Pacific Basin Climate2021Inngår i: Frontiers in Plant Science, E-ISSN 1664-462X, Vol. 12, artikkel-id 702442Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Dendroclimatic reconstructions, which are a well-known tool for extending records of climatic variability, have recently been expanded by using wood anatomical parameters. However, the relationships between wood cellular structures and large-scale climatic patterns, such as El Nino-Southern Oscillation (ENSO) and the Pacific Decadal Oscillation (PDO), are still not completely understood, hindering the potential for wood anatomy as a paleoclimatic proxy. To better understand the teleconnection between regional and local climate processes in the western United States, our main objective was to assess the value of these emerging tree-ring parameters for reconstructing climate dynamics. Using Confocal Laser Scanning Microscopy, we measured cell lumen diameter and cell wall thickness (CWT) for the period 1966 to 2015 in five Douglas-firs [Pseudotsuga menziesii (Mirb.) Franco] from two sites in eastern Arizona (United States). Dendroclimatic analysis was performed using chronologies developed for 10 equally distributed sectors of the ring and daily climatic records to identify the strongest climatic signal for each sector. We found that lumen diameter in the first ring sector was sensitive to previous fall-winter temperature (September 25(th) to January 23(rd)), while a precipitation signal (October 27(th) to February 13(th)) persisted for the entire first half of the ring. The lack of synchronous patterns between trees for CWT prevented conducting meaningful climate-response analysis for that anatomical parameter. Time series of lumen diameter showed an anti-phase relationship with the Southern Oscillation Index (a proxy for ENSO) at 10 to 14year periodicity and particularly in 1980-2005, suggesting that chronologies of wood anatomical parameters respond to multidecadal variability of regional climatic modes. Our findings demonstrate the potential of cell structural characteristics of southwestern United States conifers for reconstructing past climatic variability, while also improving our understanding of how large-scale ocean-atmosphere interactions impact local hydroclimatic patterns.

    Modeling gas transport in the shallow subsurface in the Maguelone field experiment2013Konferansepaper (Annet (populærvitenskap, debatt, mm))
    Abstract [en]

    Developing reliable monitoring techniques to detect and characterize CO2 leakage in shallow subsurface is necessary for the safety of any GCS project. To test different monitoring techniques, shallow injection-monitoring experiment have and are being carried out at the Maguelone, along the Mediterranean lido of the Gulf of Lions, near Montpellier, France. This experimental site was developed in the context of EU FP7 project MUSTANG and is documented in Lofi et al. (2012). Gas injection experiments are being carried out and three techniques of pressure, electrical resistivity and seismic monitoring have been used to detect the nitrogen and CO2 release in the near surface environment. In the present work we use the multiphase and multicomponent TOUGH2/EOS7CA model to simulate the gaseous nitrogen and CO2 transport of the experiments carried out so far. The objective is both to gain understanding of the system performance based on the model analysis as well as to further develop and validate modelling approaches for gas transport in the shallow subsurface, against the well-controlled data sets. Numerical simulation can also be used for the prediction of experimental setup limitations. We expect the simulations to represent the breakthrough time for the different tested injection rates. Based on the hydrogeological formation data beneath the lido, we also expect the vertical heterogeneities in grain size distribution create an effective capillary barrier against upward gas transport in numerical simulations.

    Pore-scale modeling of wettability effects on CO2-brine displacement during geological storage2016Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Wetting properties of reservoir rocks and caprocks can significantly influence on sequestration of carbon dioxide in deep geological formations. Wettability impacts on the physical and chemical processes that are associated with injecting CO2 underground. Our aim is to understand how wetting properties influence two-phase flow of CO2 and brine in a pore scale domain. We use the phase field method to simulate the two-phase flow of CO2-brine in realistic porous domain geometry. Our focus is on clarifying the pore-scale fluid-fluid displacement mechanisms under different wetting conditions and to quantifying the effect of contact angle on macroscopic parameters such as residual brine saturation, capillary pressure, and specific interfacial area. We could show the phase field method can be applied to a complex porous medium with realistic reservoir permeability. Beside it was shown that it can deal with the conditions with large viscosity contrasts and large wettability (low contact angles) which are difficult to handle with direct numerical approaches. Our simulations results suggest wettability concept cannot be explained just by contact angles. Even though the wettability in pore-scale is defined as the contact angle, there is not any particular relation to link the contact angle to the residual saturations and distribution patterns of CO2 in porous domain. Beside the contact angle, the flow rate and basic properties of fluids which are represent in capillary number and mobility number definitions and also the geometry of porous media are describe the CO2-brine distributions.

    Environmental drivers ofSphagnumgrowth in peatlands across the Holarctic region2021Inngår i: Journal of Ecology, ISSN 0022-0477, E-ISSN 1365-2745, Vol. 109, nr 1, s. 417-431Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The relative importance of global versus local environmental factors for growth and thus carbon uptake of the bryophyte genusSphagnum-the main peat-former and ecosystem engineer in northern peatlands-remains unclear. We measured length growth and net primary production (NPP) of two abundantSphagnumspecies across 99 Holarctic peatlands. We tested the importance of previously proposed abiotic and biotic drivers for peatland carbon uptake (climate, N deposition, water table depth and vascular plant cover) on these two responses. Employing structural equation models (SEMs), we explored both indirect and direct effects of drivers onSphagnumgrowth. Variation in growth was large, but similar within and between peatlands. Length growth showed a stronger response to predictors than NPP. Moreover, the smaller and denserSphagnum fuscumgrowing on hummocks had weaker responses to climatic variation than the larger and looserSphagnum magellanicumgrowing in the wetter conditions. Growth decreased with increasing vascular plant cover within a site. Between sites, precipitation and temperature increased growth forS. magellanicum. The SEMs indicate that indirect effects are important. For example, vascular plant cover increased with a deeper water table, increased nitrogen deposition, precipitation and temperature. These factors also influencedSphagnumgrowth indirectly by affecting moss shoot density. Synthesis. Our results imply that in a warmer climate,S. magellanicumwill increase length growth as long as precipitation is not reduced, whileS. fuscumis more resistant to decreased precipitation, but also less able to take advantage of increased precipitation and temperature. Such species-specific sensitivity to climate may affect competitive outcomes in a changing environment, and potentially the future carbon sink function of peatlands.

    Climate, Agriculture, and Migration: Exploring the Vulnerability and Outmigration Nexus in the Indian Himalayan Region2022Inngår i: Mountain Research and Development Journal, ISSN 0276-4741, E-ISSN 1994-7151, Vol. 42, nr 2, s. R9-R21Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Climate change is increasingly affecting mountain communities around the world with major implications for human livelihoods and wellbeing. With its predominantly rural population and limited resources, the Indian Himalayan Region is particularly vulnerable. While previous research has highlighted the destructive potential of climate change, we focused on the socioeconomic and ecological drivers of climate vulnerabilities and their links to migration and depopulation trends, which can be observed in the area. A mixed-methods case study approach was used to explore these relationships in the state of Uttarakhand in the western Indian Himalayan Region. Combining evidence from an aggregate vulnerability index, migration data, and insights from qualitative interviews, we found a close link between local climate vulnerabilities and migration. Considering different drivers, we show that limited adaptive capacities are the decisive factor shaping vulnerabilities and migration in the region, in particular, the high dependency on rainfed agriculture together with ecological, infrastructural, human, and financial constraints. With higher vulnerability, migrants tend to become younger, engage more in short-term migration, and increasingly employ migration in response to structural vulnerabilities and livelihood risks. The outmigration of young males has major implications for their origin communities, as the population left behind becomes older and more feminized.

    Thinking systemically about climate services: Using archetypes to reveal maladaptation2024Inngår i: Climate Services, E-ISSN 2405-8807, Vol. 34, artikkel-id 100490Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Developing and implementing climate adaptation measures in complex socio-ecological systems can lead to unintended consequences, especially when those systems are undergoing rapid hydro-climatic and socio-economic change. In these dynamic contexts, a systemic approach can make the difference between adaptive and maladaptive outcomes. This paper focuses on the use of climate services, often touted as no-regret solutions, and their potential to generate maladaptation. We explored the interactions between climate services and adaptation/maladaptation across five case studies affected by different types of natural hazards and characterized by a range of hydro-climatic and socio-economic conditions. Using system archetypes, we show how climate services can play a role in both producing and preventing maladaptation. The dynamics explored through system archetypes are: i) “fixes that fail”, where short-sighted solutions fail to address the root causes of a problem; ii) “band aid solutions”, where the benefits brought about in the short-term come at the expenses of delaying long-term adaptive actions; and iii) “success to the successful”, where some groups increasingly benefit from climate services at the expenses of other groups. We demonstrate how these dynamics constitute maladaptive processes, as well as identifying the tools and theories that can be used in this type of assessment. Finally, we provide a framework and recommendations to guide the ex-ante assessment of maladaptation risk when designing and implementing climate services.

    The 4.2 ka BP Event in the Mediterranean region: an overview2019Inngår i: Climate of the Past, ISSN 1814-9324, E-ISSN 1814-9332, Vol. 15, nr 2, s. 555-577Artikkel, forskningsoversikt (Fagfellevurdert)
    Abstract [en]

    The Mediterranean region and the Levant have returned some of the clearest evidence of a climatically dry period occurring around 4200 years ago. However, some regional evidence is controversial and contradictory, and issues remain regarding timing, progression, and regional articulation of this event. In this paper, we review the evidence from selected proxies (sea-surface temperature, precipitation, and temperature reconstructed from pollen, delta O-18 on speleothems, and delta O-18 on lacustrine carbonate) over the Mediterranean Basin to infer possible regional climate patterns during the interval between 4.3 and 3.8 ka. The values and limitations of these proxies are discussed, and their potential for furnishing information on seasonality is also explored. Despite the chronological uncertainties, which are the main limitations for disentangling details of the climatic conditions, the data suggest that winter over the Mediterranean involved drier conditions, in addition to already dry summers. However, some exceptions to this prevail - where wetter conditions seem to have persisted - suggesting regional heterogeneity in climate patterns. Temperature data, even if sparse, also suggest a cooling anomaly, even if this is not uniform. The most common paradigm to interpret the precipitation regime in the Mediterranean - a North Atlantic Oscillation-like pattern - is not completely satisfactory to interpret the selected data.

    Faithful Stewards of God's Creation?: Swedish Evangelical Denominations and Climate Change2022Inngår i: Religions, E-ISSN 2077-1444, Vol. 13, nr 5, artikkel-id 465Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Studies from the United States (U.S.) show that opposition to climate policy is strong among some Christian groups, especially White evangelical Protestants. Much of this opposition is channelled through organisations such as the Cornwall Alliance, which argue against climate measures on religious, economic and what they claim to be science-based grounds. In the present study, we investigated to what extent these convictions were present among Swedish evangelical denominations. Representatives from the Evangelical Free Church, the Pentecostal Alliance, the Swedish Alliance Mission, and the Seventh-day Adventist Church were interviewed to identify the denominations' views on the scientific underpinnings of climate change and the moral implications of climate policy. Our data show that the denominations' views differ markedly from those expressed by climate-oppositional evangelical groups in the U.S. The denominations held homogenous views on the legitimacy of climate science, expressed a clear biblical mandate for climate policy based on the notion of human stewardship, and believed that climate change was inextricably linked to poverty and, thus, had to be addressed. Our results point to the need for further studies on the factors behind acceptance and denial of climate science within and between faith-based and other communities in different countries.

    Global response of glacier runoff to twenty-first century climate change2014Inngår i: J GEOPHYS RES-EARTH, ISSN 2169-9003, Vol. 119, nr 4, s. 717-730Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The hydrology of many important river systems in the world is influenced by the presence of glaciers in their upper reaches. We assess the global-scale response of glacier runoff to climate change, where glacier runoff is defined as all melt and rain water that runs off the glacierized area without refreezing. With an elevation-dependent glacier mass balance model, we project monthly glacier runoff for all mountain glaciers and ice caps outside Antarctica until 2100 using temperature and precipitation scenarios from 14 global climate models. We aggregate results for 18 glacierized regions. Despite continuous glacier net mass loss in all regions, trends in annual glacier runoff differ significantly among regions depending on the balance between increased glacier melt and reduction in glacier storage as glaciers shrink. While most regions show significant negative runoff trends, some regions exhibit steady increases in runoff (Canadian and Russian Arctic), or increases followed by decreases (Svalbard and Iceland). Annual glacier runoff is dominated by melt in most regions, but rain is a major contributor in the monsoon-affected regions of Asia and maritime regions such as New Zealand and Iceland. Annual net glacier mass loss dominates total glacier melt especially in some high-latitude regions, while seasonal melt is dominant in wetter climate regimes. Our results highlight the variety of glacier runoff responses to climate change and the need to include glacier net mass loss in assessments of future hydrological change.

    Changing Arctic snow cover: A review of recent developments and assessment of future needs for observations, modelling, and impacts2016Inngår i: Ambio, ISSN 0044-7447, E-ISSN 1654-7209, Vol. 45, nr 5, s. 516-537Artikkel, forskningsoversikt (Fagfellevurdert)
    Abstract [en]

    Snow is a critically important and rapidly changing feature of the Arctic. However, snow-cover and snowpack conditions change through time pose challenges for measuring and prediction of snow. Plausible scenarios of how Arctic snow cover will respond to changing Arctic climate are important for impact assessments and adaptation strategies. Although much progress has been made in understanding and predicting snow-cover changes and their multiple consequences, many uncertainties remain. In this paper, we review advances in snow monitoring and modelling, and the impact of snow changes on ecosystems and society in Arctic regions. Interdisciplinary activities are required to resolve the current limitations on measuring and modelling snow characteristics through the cold season and at different spatial scales to assure human well-being, economic stability, and improve the ability to predict manage and adapt to natural hazards in the Arctic region.

    Key indicators of Arctic climate change: 1971–20172019Inngår i: Environmental Research Letters, E-ISSN 1748-9326, Vol. 14, nr 4, s. 1-18, artikkel-id 045010Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Key observational indicators of climate change in the Arctic, most spanning a 47 year period (1971–2017) demonstrate fundamental changes among nine key elements of the Arctic system. We find that, coherent with increasing air temperature, there is an intensification of the hydrological cycle, evident from increases in humidity, precipitation, river discharge, glacier equilibrium line altitude and land ice wastage. Downward trends continue in sea ice thickness (and extent) and spring snow cover extent and duration, while near-surface permafrost continues to warm. Several of the climate indicators exhibit a significant statistical correlation with air temperature or precipitation, reinforcing the notion that increasing air temperatures and precipitation are drivers of major changes in various components of the Arctic system. To progress beyond a presentation of the Arctic physical climate changes, we find a correspondence between air temperature and biophysical indicators such as tundra biomass and identify numerous biophysical disruptions with cascading effects throughout the trophic levels. These include: increased delivery of organic matter and nutrients to Arctic near‐coastal zones; condensed flowering and pollination plant species periods; timing mismatch between plant flowering and pollinators; increased plant vulnerability to insect disturbance; increased shrub biomass; increased ignition of wildfires; increased growing season CO2 uptake, with counterbalancing increases in shoulder season and winter CO2 emissions; increased carbon cycling, regulated by local hydrology and permafrost thaw; conversion between terrestrial and aquatic ecosystems; and shifting animal distribution and demographics. The Arctic biophysical system is now clearly trending away from its 20th Century state and into an unprecedented state, with implications not only within but beyond the Arctic. The indicator time series of this study are freely downloadable at AMAP.no.

    Interactions between the atmosphere, cryosphere, and ecosystems at northern high latitudes2019Inngår i: Atmospheric Chemistry And Physics, ISSN 1680-7316, E-ISSN 1680-7324, Vol. 19, nr 3, s. 2015-2061Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The Nordic Centre of Excellence CRAICC (Cryosphere-Atmosphere Interactions in a Changing Arctic Climate), funded by NordForsk in the years 2011-2016, is the largest joint Nordic research and innovation initiative to date, aiming to strengthen research and innovation regarding climate change issues in the Nordic region. CRAICC gathered more than 100 scientists from all Nordic countries in a virtual centre with the objectives of identifying and quantifying the major processes controlling Arctic warming and related feedback mechanisms, outlining strategies to mitigate Arctic warming, and developing Nordic Earth system modelling with a focus on short-lived climate forcers (SLCFs), including natural and anthropogenic aerosols. The outcome of CRAICC is reflected in more than 150 peer-reviewed scientific publications, most of which are in the CRAICC special issue of the journal Atmospheric Chemistry and Physics. This paper presents an overview of the main scientific topics investigated in the centre and provides the reader with a state-of-the-art comprehensive summary of what has been achieved in CRAICC with links to the particular publications for further detail. Faced with a vast amount of scientific discovery, we do not claim to completely summarize the results from CRAICC within this paper, but rather concentrate here on the main results which are related to feedback loops in climate change-cryosphere interactions that affect Arctic amplification.

    Extreme dry and wet spells face changes in their duration and timing2020Inngår i: Environmental Research Letters, E-ISSN 1748-9326, Vol. 15, nr 7, artikkel-id 074040Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Dry spells are sequences of days without precipitation. They can have negative implications for societies, including water security and agriculture. For example, changes in their duration and within-year timing can pose a threat to food production and wildfire risk. Conversely, wet spells are sequences of days with precipitation above a certain threshold, and changes in their duration and within-year timing can impact agriculture, flooding or the prevalence of water-related vector-borne diseases. Here we assess changes in the duration and within-year timing of extreme dry and wet spells over 60 years (1958-2017) using a consistent global land surface precipitation dataset of 5093 rain gauge locations. The dataset allowed for detailed spatial analyses of the United States, Europe and Australia. While many locations exhibit statistically significant changes in the duration of extreme dry and wet spells, the changes in the within-year timing are less often significant. Our results show consistencies with observations and projections from state-of-the-art climate and water resources research. In addition, we provide new insights regarding trends in the timing of extreme dry and wet spells, an aspect being equally important for possible future implications of extremes in a changing climate, which has not yet received the same level of attention and is characterized by larger uncertainty.

    Borderless Heat Hazards With Bordered Impacts2021Inngår i: Earth's Future, E-ISSN 2328-4277, Vol. 9, nr 9, artikkel-id e2021EF002064Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Heatwaves are increasing in frequency, duration, and intensity due to climate change. They are associated with high mortality rates and cross-sectional impacts including a reduction in crop yield and power outages. Here we demonstrate that there are large deficiencies in reporting of heatwave impacts in international disasters databases, international organization reports, and climate bulletins. We characterize the distribution of heat stress across the world focusing on August in the Northern Hemisphere, when notably heatwaves have taken place (i.e., 2003, 2010, and 2020) for the last 20 years using the ERA5-HEAT reanalysis of the Universal Thermal Comfort Index and establish heat stress has grown larger in extent, more so during a heatwave. Comparison of heat stress against the emergency events impacts database and climate reports reveals underreporting of heatwave-related impacts. This work suggests an internationally agreed protocol should be put in place for impact reporting by organizations and national government, facilitating implementation of preparedness measures, and early warning systems.

    Thermofeel: A python thermal comfort indices library2022Inngår i: SoftwareX, E-ISSN 2352-7110, Vol. 18, artikkel-id 101005Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Here the development of the python library thermofeel is described. thermofeel was developed so that prominent internationally used thermal indices (i.e. Universal Thermal Climate Index and Wet Bulb Globe Temperature) could be implemented into operational weather forecasting systems (i.e. the European Centre for Medium Range Weather Forecasts) whilst also adhering to open research practices. This library will be of benefit to many sectors including meteorology, sport, health and social care, hygiene, agriculture and building. In addition, it could be used in heat early warning systems which, with the right preparedness measures, has the potential to save lives from thermal extremes.

    Wet Bulb Globe Temperature: Indicating Extreme Heat Risk on a Global Grid2023Inngår i: GeoHealth, E-ISSN 2471-1403, Vol. 7, nr 2, artikkel-id e2022GH000701Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The Wet Bulb Globe Temperature (WBGT) is an international standard heat index used by the health, industrial, sports, and climate sectors to assess thermal comfort during heat extremes. Observations of its components, the globe and the wet bulb temperature (WBT), are however sparse. Therefore WBGT is difficult to derive, making it common to rely on approximations, such as the ones developed by Liljegren et al. and by the American College of Sports Medicine (WBGT(ACSM87)). In this study, a global data set is created by implementing an updated WBGT method using ECMWF ERA5 gridded meteorological variables and is evaluated against existing WBGT methods. The new method, WBGT(Brimicombe), uses globe temperature calculated using mean radiant temperature and is found to be accurate in comparison to WBGT(Liljegren) across three heatwave case studies. In addition, it is found that WBGT(ACSM87) is not an adequate approximation of WBGT. Our new method is a candidate for a global forecasting early warning system.

    CLIMATE CHANGE AND THE ELECTRICAL DISTRIBUTION GRIDS OF GOTLAND AND KLINTEHAMN2023Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    Climate change represents a critical threat to electrical infrastructure. With reliance on electricity expected to increase in Sweden due to the transition from fossil fuel based energy to greener energy sources, it is important that the reliability of the electrical grid be upheld. This thesis studies the potential climate affected effects of extreme precipitation, annual average temperature change, water pooling after 100/500-year rains, and sea level rise. The RCP scenarios used for extreme precipitation and temperature change are RCP 4.5 and RCP 8.5. These climate effects will be studied in this thesis to understand and determine the extent of the climate effects on the electrical grid of Gotland and Klintehamn. The possible issues on infrastructure that can be exacerbated by these climate effects will be presented. This thesis will use spatial analysis to find results using GIS as a tool. GIS will be used to compare the various climate effects over the electrical grid data. Data was received from various sources, extreme precipitation and temperature change were sourced from SMHI, water pooling, and sea level rise were sourced with permission from Region Gotland. The electrical grid data for both Gotland and Klintehamn was received from GEAB, this data is considered nationally sensitive information therefore the location of this data is not shown.

    The results generally show that climate change, no matter the scenario presents a threat to the infrastructure. Although it should be noted as well that the scenario will impact the severity of the effects. RCP 8.5 will likely have more of an effect for both extreme precipitation and temperature than RCP 4.5. Water pooling is expected to have a greater effect on the <20kV lines than on the 70kV infrastructure. Finally, sea level rise is expected to have a much greater effect from 2-meter sea level rise over the 1-meter sea level rise. The overarching theme found is that climate change will have impacts over the electrical grid.

    Abstract [en]

    This framing chapter has two primary purposes: to provide a frame-work for viewing and understanding the human (social) perspective on climate change, focusing on ethics and economics; and to define and discuss key concepts used in other chapters. It complements the two other framing chapters: Chapter 2 on risk and uncertainty and Chapter 4 on sustainability. The audience for this chapter (indeed for this entire volume) is decision makers at many different levels. The significance of the social dimension and the role of ethics and economics is underscored by Article 2 of the United Nations Framework Convention on Climate Change (UNFCCC), which indicates that the ultimate objective of the Convention is to avoid dangerous anthropogenic interference with the climate system. Two main issues confronting society are: what constitutes ‘dangerous interference’ with the climate system and how to deal with that interference (see box 3.1). Providing information to answer these inter-related questions is a primary purpose of the IPCC. Although natural science helps us understand how emissions can change the climate, and, in turn, generate physical impacts on ecosystems, people, and the physical environment, determining what is dangerous involves judging the level of adverse consequences, the steps necessary to mitigate these consequences, and the risk that humanity is willing to tolerate. These are questions requiring value judgement. Although economics is essential to evaluating the consequences and trade-offs associating with climate change, how society interprets and values them is an ethical question. Our discussion of ethics centres on two main considerations: justice and value. Justice requires that people and nations should receive what they are due, or have a right to. For some, an outcome is just if the process that generated it is just. Others view justice in terms of the actual outcomes enjoyed by different people and groups and the values they place on those outcomes.

    Quantification, the link to relate climate-induced damage to indoor environments in historic buildings2013Inngår i: Climate for collections: Standards and uncertainties: Postprints of the Munich Climate Conference 7 to 9 November 2012 / [ed] Jonathan Ashley-Smith, Andreas Burmester and Melanie Eibl, 2013, s. 311-323Konferansepaper (Fagfellevurdert)
    Abstract [en]

    This paper describes and applies a method to quantify and related damage of painted wooden pulpits in 16 churches in Gotland, Sweden, to both the current and the historical indoor climate of the twentieth century. In addition, it demonstrates that the energy used to heat a church in the past can be measured and the study alsopoints towards a relationship between damage and heat output. The results suggest that more damage is present in churches with a higher heat output and there is increased damage in churches using background heating compared to churches that do not. However, the method needs to be improved and a larger population is required to validate these results.
