The climate system is undergoing rapid changes because of anthropogenic emissions of greenhouse gases. The effects from a warmer climate are already noticeable today with more frequent extreme weather events. These extreme weather events have financial consequences and pose risks to the financial system. This study evaluates such physical climate risks for the periods 2021-2025 and 2026-2030 by developing a quantitative model. Physical risks are here limited to heat waves, heavy precipitation events, drought and tropical cyclones. The model applies climate data from CMIP5 to evaluate hazard intensity at the location of a company. Vulnerability of the certain hazard is determined based on the sector. Physical risks from supply chain relations are also considered. The result is then aggregated on portfolio level. The model is applied to compare the exposure of physical climate risks on sustainable equity funds with the exposure on the general market and to determine what characteristics that contribute to low respectively high climate risks. Generally, the total climate risk proves to be lower for the period 2021-2025 compared to 2026-2030 because of the natural variability in the climate system. Europe has the lowest climate risk, and the GICS-sector with the highest risk is Real Estate. No clear conclusion can be drawn in the comparison of physical risk exposure between sustainable funds and the market; however, the result indicates that sustainable funds select securities of lower risk within a specific investment universe. The average sustainable funds select equities with lower risk within regions, sectors and market cap sizes in almost all studied cases. Regional allocation proves to be important for the exposure to physical climate risks. This is also related to market cap size since larger companies are likely to have their assets distributed in several countries which contributes to diversification. On fund level, the strategy of carbon minimising is shown to have no significant impact on physical climate risks, neither positively nor negatively. The awareness among investors on physical climate risks is currently low, and sustainability labels seem to offer no guarantee for minimising physical risk exposure. This study adds to the very small pool of studies on physical climate risks in investment management and provides a market wide overview. Hopefully, development of this research area can contribute to increase the awareness of investors and thereby drive capital towards a more resilient society. / Klimatet genomgår en snabb förändring på grund av antropogena utsläpp av växthusgaser. Effekterna av ett varmare klimat är redan kännbara idag med mer frekventa extremväderhändelser. De här extremväderhändelserna har finansiella konsekvenser och utgör en risk för det finansiella systemet. Den här studien utvärderar sådan fysisk klimatrisk för perioderna 2021-2025 och 2026-2030 genom att utveckla en kvantitativ modell. I begreppet fysiska klimatrisker innefattas här värmeböljor, kraftiga skyfall, torka och tropiska cykloner. Modellen använder sig av klimatdata från CMIP5 för att utvärdera intensiteten av naturfenomenet på den geografiska platsen för företagets tillgångar. Känslighet för naturfenomenet bestäms baserat på sektorn. Fysiska risker från värdekedjan inkluderas också. Resultatet är sedan aggregerat på portföljnivå. Modellen är applicerad för attjämföra fysiska klimatrisker för hållbarhetsfonder jämfört med den generella marknaden och för att bestämma vilka faktorer som bidrar till en hög respektive låg klimatrisk. Generellt visades att den fysiska klimatrisken var lägre för perioden 2021-2025 jämfört med perioden 2026-2030 på grund av naturlig variabilitet i klimatsystemet. Europa hade den lägsta klimatrisken, och GICS-sektorn med högst risk var fastighetssektorn. Ingen tydlig slutsats kan dras i jämförelsen av klimatrisk för hållbarhetsfonder och marknaden, men resultatet indikerar att hållbarhetsfonder väljer aktier med lägre klimatrisk inom ett specifikt investeringsunivers. Den genomsnittliga hållbarhetsfonden väljer aktier med lägre risk inom regioner, sektorer och market-cap storlek i nästan alla studerade fall. Regional allokering visade sig vara en viktig faktor för exponering av klimatrisk. Det relaterar också till storlek av företaget eftersom större företag är mer troliga att ha tillgångarna fördelade i flera länder vilket bidrar till diversifiering. På fondnivå visades att strategin att minimera koldioxidintensitet inte påverkar klimatrisken signifikant, varken negativ eller positiv. Medvetenheten om fysisk klimatrisk bland investerare är idag låg, och hållbarhetsmärkningar tycks inte innebära någon garanti för att minimera exponeringen till fysisk klimatrisk. Den här studien bidrar till den mycket lilla gruppen av studier inom fysisk klimatrisk i investeringar och erbjuder en överblick över hela marknaden. Förhoppningsvis kan utveckling av detta forskningsområde bidra till att öka medvetenheten hos investerare och därmed driva kapital mot ett mer resilient samhälle.

This report investigates inconsistencies in climate policy engagement of 16 major corporations in five industrial sectors and analyses which problem areas are significant in the inconsistency of their engagement. The purpose of this report was to scope the area of inconsistent climate policy engagement on behalf of the company GES International – Global Engagement Services, who offers advisory services in responsible investment. This report has been performed through a literature review and is partly based on a report on corporate carbon policy footprint by the independent organisation InfluenceMap.   All companies investigated in this report are to some extent supporting the climate agenda of the Paris Agreement, including limiting global warming to below two degrees. Nevertheless, 14 of the 16 companies are at the same time showing a negative climate policy engagement. The problem areas leading up to this inconsistency that have been detected in this report are; when companies are taking part in organisational relationships that are unsupportive of climate change mitigation strategies, when companies are against climate legislation, the unwillingness of companies to change their own industrial sector and companies showing mixed signals on the same policy topic.   The conclusions that can be drawn from this report is that there are substantial inconsistencies in the climate policy engagement of companies and it can be difficult to assess what the company’s true stance on climate engagement is. Some measures to improve on consistency is for companies to review their policy engagement and be transparent on what their actual stance climate engagement is, however this transition can take time. / Den här rapporten undersöker inkonsekvenser inom klimatpolicy engagemang hos 16 av världens största företag, inom fem olika sektorer, och analyser vilka problemområden som är betydande inom motsägande klimatengagemang hos företagen. Syftet med rapporten är att granska området kring inkonsekvent klimatpolicy engagemang på uppdrag av företaget GES International – Global Engagement Services, som erbjuder rådgivning inom hållbara investeringar. Rapporten har utförts genom en litteraturstudie som delvis är baserad på en rapport om företags påverkan på klimatet genom policys som är utgiven av den oberoende organisationen InfluenceMap.   Samtliga företag som undersöks i den här rapporten visar sig till viss del stödja klimatagendan i enlighet med Parisavtalet, vilket inkluderar en höjd global temperatur på max två grader. Trots detta visar sig 14 av de 16 företagen ha en distinkt negativ klimatpolicy engagemang som strider mot deras erkännande av Parisavtalet. De identifierade problem i den här rapporten som leder till motsägande klimatengagemang hos företagen är; när företagens organisatoriska relationer som arbetar strategiskt mot att förbättra klimatförändringar, när företagen strategiskt arbetar för att motverka lagstiftande om klimat, när företag är emot att inkludera sin egen sektor i klimatarbetet och när företagen visar olika åsikter inom samma ämne.   Slutsatsen som kan dras från den här rapporten är att det finns substantiella motsägelser i företagens klimatpolicy engagemang och det kan vara svårt att avgöra vilken som är den sanna inställningen hos företagen. För att för att göra företagens klimatengagemang mer konsekvent kan företagen till exempel granska sina egna engagemang och vara transparenta med vad deras egentliga inställning till klimatet är. Omställning till ett mer konsekvent klimatengagemang hos företagen kan ta lång tid.

The creation of futures scenarios is a tool to addresschallenges towards sustainability in planning and thebuilt environment. Scenarios in the project BeyondGDP growth explore futures where priority is givento social and environmental aspects and economicgrowth is regarded as uncertain. When futures areused as an input to planning, there has to be anawareness of the possible consequences of those.Sustainability assessment for futures scenarios aimsto give a comprehensive assessment of how differentscenarios can affect relevant aspects. This thesis gives an overview of current methods forsustainability assessment of futures scenarios. It alsoproposes improvements to one of them and tests iton the Beyond GDP growth scenarios. SAFS (SustainabilityAssessment Framework for Scenarios) isthe method selected. SAFS considers environmentaland social aspects providing qualitative results anduses consumption perspective and life cycle approach. Improvements to SAFS are proposed in two directions.First, the Doughnut developed by Raworth(2012) is integrated in the method. It gives a graphicrepresentation, putting each aspect in context withthe others and facilitate the communication of theassessment results. Second, an alternative approachis suggested to evaluate the consequences of environmentaldeprivation on social conditions. Thisalternative approach can also help communicateuncertainties. / Att skapa framtidsscenarier är ett verktyg för attadressera utmaningar relaterade till hållbarhet inomsamhällsplanering och samhällsbyggnad.

Arctic warming is assumed to be four times the global warming. A published study by Ivanov et al. (2019) shows that the annual average temperature of Franz Joseph Land (the world’s northernmost island region, a Russian territory) has increased by 5.2 °C from 2000-2017. This result supported the idea of determining whether Svalbard (Norwegian territory) is experiencing similar warming. Svalbard has historically been an attractive research center for examining climate change in the Arctic. Due to easier accessibility, the vast majority of weather stations have been located on the western part of the main island, Spitsbergen, which does not provide a representative picture of the entire archipelago. Therefore, this project has focused on eastern Spitsbergen. Data from six stations have been processed to analyze the temperature changes based on linear regression (the same method as at Franz Joseph Land). As eastern Spitsbergen has never been a priority, only short datasets are available, with the longest one dating from 2009. Because of this, no statistically significant result could be elucidated. Instead, data from Longyearbyen, which is located southwest were implemented, allowing analysis over the same period as Franz Joseph Land (2000-2017). This result suggested a temperature increase of 5.6 °C for the same period, with a statistical significance of P = 0.13, as well as that the winters are extra vulnerable to warming. The stations from eastern Spitsbergen’s local variability were also examined, which showed that the local climate varies although the stations are relatively close. Among others, Pyramiden seemed to be most affected by the lapse rate feedback, meaning a significant strong warming at the surface.

Permafrost deformation is expected to increase due to climatic perturbations such as amplified air and soil temperatures, resulting in permafrost thawing and subsequent subsidence. Palsas and peat plateaus are uplifted ice-rich peat mounds that experience permafrost subsidence. This is due to the uppermost layer of permafrost, known as the Active Layer (AL), that seasonally thaws and freezes. Interferometric Synthetic Aperture Radar (InSAR) is an interferometric stacking technique successfully applied over permafrost regions when monitoring ground subsidence. The Small Baseline Subset (SBAS) technique is based on interferograms produced by stacking Synthetic Aperture Radar (SAR) acquisitions with small normal baselines. In this study, seasonal Sentinel-1 SAR C-band data obtained during June, July, August and September (JJAS) was used to generate seasonal Line of Sight (LoS) deformation time series of palsas and peat plateaus in Tavvavuoma (Sweden) by using the SBAS technique. Chersky (Russia) has documented permafrost subsidence and was used as a reference site. Findings include that seasonal stacks with short normal baselines generated more robust results than inter-annual stacks with longer normal baselines and temporal data gaps. No instances of pronounced subsidence were reported during JJAS. Nevertheless, minor subsidence during the early season and negative development trends were identified in the Tavvavuoma 2020 andChersky 2020-2021 stacks, respectively. Increased subsidence during the mid-and late thaw season was detected. The SBAS technique performed better and resulted in less temporal and seasonal decorrelation in areas above the tree line (Tavvavuoma) compared to the lowlands in the forest-tundra (Chersky). The challenge lies in whether surface subsidence of palsas and peat plateaus in sporadic permafrost regions experience irreversible long-term changes or seasonally cyclic changes in the permafrost ground regime. Future studies are recommended to implement annual intervals, including winter images over Tavvavuoma.

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.

Sea ice is a vital component of the cryosphere and does not only influence the polar regions but has a more global influence. Indeed, sea ice plays a major role in the regulation of the global climate system as the sea ice cover reflects the sun radiation back to the atmosphere keeping the polar regions cool. The shrinkage of the sea ice cover entails the warming up of the oceans and as a consequence, a further amplification of the melting of sea ice. Therefore, the polar regions are sensitive to climate change and monitoring the sea ice cover is very important. To assess sea ice change in the polar regions, satellite active microwave sensors, scatterometers, are used to observe the evolution of sea ice extent and sea ice types. Thus, this research aims at creating a historic record of daily global Arctic and Antarctic sea ice extents and analysing the change in sea ice types with scatterometer data. A Bayesian sea ice detection algorithm, developed for the Advanced scatterometer (ASCAT), is applied and tuned to the configurations of the scatterometers on board the European Remote Sensing satellites, ERS\textendash 1 and ERS\textendash 2. The sea ice geophysical model functions (GMFs) of ERS and ASCAT are studied together to validate the use of ASCAT sea ice GMF extrapolated to the lower incidence angles of ERS. The main adaptations from the initial algorithm aim at compensating for the lower observation densities afforded by ERS with a refined spatial filter and time\textendash variable detection thresholds. To further analyse the backscatter response from sea ice and derive information on the different sea ice types, a new model of sea ice backscattering at C\textendash band is proposed in this study. This model has been derived using ERS and ASCAT backscatter data and describes the variation of sea ice backscatter with incidence angle as a function of sea ice type. The improvement of the sea ice detection algorithm for ERS\textendash 1 and ERS\textendash 2, operating between 1992 and 2001, leads to the extension of the existing records of daily global sea ice extents from the Quick scatterometer (QuikSCAT) which operated from 1999 to 2009 and ASCAT operating from 2007 onwards. The sea ice extents from ERS, QuikSCAT and ASCAT show excellent agreement during the overlapping periods, attesting to the consistency and homogeneity of the long\textendash term scatterometer sea ice record. The new climate record is compared against passive microwave derived sea ice extents, revealing consistent differences between spring and summer which are attributed to the lower sensitivity of the passive microwave technique to melting sea ice. The climate record shows that the minimum Arctic summer sea ice extent has been declining, reaching the lowest record of sea ice extent in 2012. The new model for sea ice backscatter is used on ERS and ASCAT backscatter data and provides a more precise normalization of sea ice backscatter than was previously available. An application of this model in sea ice change analysis is performed by classifying sea ice types based on their normalized backscatter values. This analysis reveals that the extent of multi\textendash year Arctic sea ice has been declining remarkably over the period covered by scatterometer observations.

The world's seas are without a doubt being changed by global warming, affecting all species, causing ecosystem changes. The overall low biodiversity in the Baltic Sea leads to sensitive unique qualities. Understanding how climate change in the Baltic Sea will affect key species is important to understanding how the Baltic Sea coastal environment will look in the future. Fucus vesiculosus, and Zostera marina, are key habitat building vegetation in the Baltic Sea, building up most of the canopies by the coasts on rocky and sandy bottoms. How are these species affected by climate change in the Baltic Sea? The result showed that both Fucus and Zostera growth is stimulated during most of the year with rising temperatures, but during summer heatwaves inhibit the plants, raising the mortality. Fucus will migrate more south, as the Baltic Sea will likely become fresher, and Zostera will continue to thrive if nutrients are reduced. Both species will experience die-offs during summer heatwaves. / Världens hav förändras utan tvekan av den globala uppvärmningen, vilket påverkar alla arter och leder till ekosystem förändringar. Den övergripande låga biologiska mångfalden i Östersjön leder till känsliga unika förhållanden. Att förstå hur klimatförändringarna i Östersjön kommer att påverka nyckelarter är viktigt för att förstå hur Östersjöns kustmiljö kommer att se ut i framtiden. Fucus vesiculosus och Zostera marina, är viktiga habitatsbildande växter i Östersjön, som bygger upp majoriteten av ekosystemen vid kusterna på steniga och sandiga bottnar. Hur påverkas dessa arter av klimatförändringar i Östersjön? Resultatet visade att tillväxten av både Fucus och Zostera stimuleras under större delen av året med stigande temperaturer, men under sommaren hämmar värmeböljor växterna, vilket ökar dödligheten. Huvudslutsatserna är att Fucus kommer att vandra mer söderut, eftersom Östersjön med största sannolikhet kommer att bli sötare från norr, och Zostera kommer fortsätta trivas om näringsmängden minskar. Båda arterna kommer drabbas av dödsfall under värmeböljor på sommaren.

Climate change is already affecting communities around the world and the impacts will only get worse, according to scientists, unless we significantly reduce greenhouse gas emissions.  These realities can lead to climate anxiety, not least among youth.  How can teachers educate students about climate change in a constructive way?  This study examines pedagogical reflections from grade school and gymnasium teachers who participated in a professional development workshop entitled “Climate workshop with a bright horizon” organized by The House of Science, the Bolin Center for Climate Research, and Stockholm City.  To address students’ climate anxiety, research says that teaching methods characterized by pluralism, democratic participation, and authenticity can be empowering to students in helping them to engage, act, and cope with unpredictability.  This study identifies opportunities to strengthen these aspects in climate education by, for example, using socio-scientific issue dialogues.
