Abstract (sommario):
Climate change is expected to adversely affect crop yields and livelihoods of agro-dependent societies, especially in Sub-Saharan Africa. However, there remain gaps on the effects of expected regional climatic changes on key food security crops. This study assessed the projected climatic conditions and expected changes in millet yields for Paicho Sub County (S/C) in Gulu District up to the year 2033 using a cross sectional study design. To determine future climatic conditions, PRECIS (Providing Regional Climates for Impact Studies) model was used based on projected conditions at a 50 km spatial resolution while millet yields were modelled using Penman Grindley soil moisture balance model. PRECIS projected changes for 2033 reveal a strong and significant decrease in rainfall (p< 0.05). This is likely to decrease millet yields by 2.6% below the average current yields of 1.8 tons per hectare per year under business-as-usual scenario. The finding indicates a need for improved millet varieties that can survive under changed climatic conditions

Abstract (sommario):
The present study tends to describe the survey of climatic changes in the case of the Bojnourd region of North Khorasan, Iran. Climate change due to a fragile ecosystem in semi-arid and arid regions such as Iran is one of the most challenging climatological and hydrological problems. Dendrochronology, which uses tree rings to their exact year of formation to analyse temporal and spatial patterns of processes in the physical and cultural sciences, can be used to evaluate the effects of climate change. In this study, the effects of climate change were simulated using dendrochronology (tree rings) and an artificial neural network (ANN) for the period from 1800 to 2015. The present study was executed using the Quercus castaneifolia C.A. Meyer. Tree-ring width, temperature, and precipitation were the input parameters for the study, and climate change parameters were the outputs. After the training process, the model was verified. The verified network and tree rings were used to simulate climatic parameter changes during the past times. The results showed that the integration of dendroclimatology and an ANN renders a high degree of accuracy and efficiency in the simulation of climate change. The results showed that in the last two centuries, the climate of the study area changed from semiarid to arid, and its annual precipitation decreased significantly.

Abstract (sommario):
Measurements on ice-core samples showed that atmospheric methane concentration changed with the large climatic cycles during the last two glaciations (Stauffer and others, 1988; Raynaud and others, 1988). The methane concentration is lower in cold periods and higher in warm periods. In this paper we discuss the results of CH4 measurements of samples from periods of minor climatic change, like the climatic optimum 8000 years B.P. and the Younger Dryas period about 10 000 to 11 000 years B.P.. The data are interpreted in terms of the present understanding of methane sources and sinks.

Abstract (sommario):
Variability and changes in climate are generally expected to occur. However, there remain gaps on dynamics of expected regional variations in climatic changes. This study assessed historic and projected climatic conditions up to the year 2033. The study hypothesized that temperature rather than rainfall significantly increased for the period 1980-2010 and rainfall rather than temperature is likely to decrease significantly by 2033 for Gulu District in northern Uganda. To determine historic climatic trends, rainfall and temperature data were obtained from Uganda National Meteorological Authority (UNMA) while for future climate, the PRECIS (Providing Regional Climates for Impact Studies) modelled data based on projected conditions at a 50 km spatial resolution was used. These data sets were subjected to trend analysis and the differences in means were detected at a 95% confidence level. Contrary to the evidences from other empirical studies, results generally indicated decreasing rainfall for the period 1980-2010. However, the decrease was not significant (P > 0.05) while both historic mean annual maximum and minimum temperature trends showed a statistically significant increase (P<0.05). Projections for 2033 reveal a significant decrease in rainfall (P < 0.05) while both maximum and minimum temperature will remain quasi uniform

Abstract (sommario):
In this study,the future simulated climatic data (temperature and rainfall) for the 21st century were downscaled using the regional climate model, viz., PRECIS model (Providing Regional Climates for Impact Studies) for different agro-climatic zones, i.e., Zone II (Ballowal Saunkhri), Zone III (Ludhiana, Amritsar, Patiala and Jalandhar) and Zone V (Bathinda) of Punjab. The corrected simulated data were then analyzed on the annual and seasonal basis to quantify the changes in maximum and minimum temperature and rainfall. The study showed that the maximum and minimum temperature and rainfall by the end of 21st century are likely to increase by 2.0 to 2.2 °C, 3.3 to 5.4 °C and 33 to 66% respectively in agro-climatic zone II; by 0.4 to 5.8 °C, 2.5 to 7.4 °C and 3 to 62% respectively in agro-climatic zone III and by 0.5 to 4.0 °C, 4.7 to 7.7 °C and 58 to 69% respectively in agro-climatic zone V at different locations of Punjab state under various scenarios of climate change. The trend analysis of these parameters revealed there is positive linear increasing trend under different scenarios in the Punjab state.

Abstract (sommario):
Abstract Anthropogenic climate change and habitat loss and deterioration affect populations worldwide. Climate warming has changed phenologies of many species across trophic levels. Some predator populations now experience temporal mismatches with their prey, as timings of peak prey abundance and of the predator’s highest food demands no longer meet. The temporal mismatch hypothesis suggests that the population’s recruitment rate is related to its degree of synchrony with the food resources needed to feed offspring. However, species’ and populations’ responses to climate warming differ. Human land use alters and destroys habitats of countless species. For example, many boreal forest bird populations have declined, presumably due to intensive forestry. It has decreased the amount of dead wood, causing a threat to saproxylic species. Identification of the key characteristics of high-quality habitats is essential for conservation planning and for developing sustainable forestry. As individuals are suspected to settle in habitats that maximize their fitness, analysis of nest site selection can be used to identify the key habitats. My dissertation concerns the impacts of climate change and habitat deterioration on boreal populations. I use hole-nesting passerines as model species. By utilizing long-term data I show that breeding phenologies of Parus major and Poecile montanus, but not of Cyanistes caeruleus, have shifted earlier. Also, the timing of the food peak has advanced, improving the synchrony between P. montanus and caterpillars. In P. major and C. caeruleus, synchrony has remained good. However, the positive effect of good synchrony on breeding success seems to be conditional, arising only in certain circumstances, such as in years of high caterpillar abundance. I suggest that in boreal populations temperature affects timing of breeding mostly as a proximate factor. The availability of standing decaying trees used for nesting sites was the most important habitat characteristic determining the nest site selection of P. montanus. Remote sensing data alone was insufficient to produce reliable models, as the ecologically important small-scale factor can only be determined by direct field surveys. Omission of forest thinning in selected forest sites would ensure the continuous availability of decaying wood with positive influence on biodiversity in managed forests
Tiivistelmä Ihmisen aiheuttama habitaattien katoaminen ja huononeminen sekä ilmastonmuutos vaikuttavat populaatioihin kaikkialla maailmassa. Ilmaston lämpeneminen on muuttanut monien lajien fenologioita eri trofiatasoilla. Osalla saalistajalajien populaatioista suurin ravinnontarve ei enää ajoitu samaan aikaan saaliin runsaushuipun kanssa. Ajoituksen eriaikaisuus -hypoteesin mukaan todennäköisyys populaatioon rekrytoitumiselle riippuu synkronian asteesta saaliin kanssa. Ilmaston lämpenemisen vaikutuksissa lajeihin ja populaatioihin on kuitenkin vaihtelua. Ihmisen maankäyttö muuttaa ja tuhoaa lukuisien lajien elinympäristöjä. Esimerkiksi useiden boreaalisten metsien lintupopulaatioiden pienentymistä on selitetty intensiivisellä metsätaloudella. Lahopuun määrä metsissä on vähentynyt, mikä on uhka lahopuusta riippuvaisille lajeille. Korkealaatuisten habitaattien keskeisten piirteiden tunnistaminen on tärkeää luonnonsuojelun ja kestävän metsätalouden suunnittelulle. Koska yksilöiden oletetaan valitsevan niiden kelpoisuutta maksimoivia elinympäristöjä, pesäpaikanvalinta-analyysiä voidaan käyttää tärkeiden habitaattipiirteiden tunnistamiseen. Tarkastelen väitöskirjassani ilmastonmuutoksen ja habitaattien laadun vaikutuksia boreaalisiin populaatioihin. Mallilajeina käytän koloissa pesiviä varpuslintuja. Hyödyntämällä pitkäaikaisaineistoja osoitan, että lisääntymisen ajoittuminen on aikaistunut tali- ja hömötiaisella, mutta ei sinitiaisella. Myös ravintohuippu on aikaistunut, mikä on parantanut synkroniaa hömötiaisen ja sen pääasiallisen ravinnon eli toukkien välillä. Tali- ja sinitiaisella synkronia on pysynyt hyvänä. Hyvän synkronian myönteinen vaikutus lisääntymismenestykseen vaikuttaa kuitenkin ehdolliselta: se tulee esiin vain tietyissä olosuhteissa, kuten vuosina jolloin toukkia on runsaasti. Kevään lämpötilat näyttävät vaikuttavan pesinnän ajoittumiseen erityisesti proksimaattisena tekijänä. Pesäpaikkoina toimivien seisovien lahopuiden määrä on tärkein hömötiaisen pesäpaikanvalintaa määräävä tekijä. Kaukokartoitusaineisto yksinään ei riitä luotettavien mallien tuottamiseen, sillä ekologisesti tärkeät pienen skaalan tekijät voidaan kartoittaa vain suorin maastomittauksin. Metsien harventamatta jättäminen valituilla laikuilla turvaisi lahopuun jatkuvan saatavuuden, mikä vaikuttaisi myönteisesti talousmetsien biodiversiteettiin

Abstract (sommario):
Mestrado em Biologia Molecular e Celular
Extreme abiotic factors, such drought combined with heat waves and/or high UVB radiation are predicted to become more frequent in the future. The impact on plant production of these challenges on multipurpose Moringa oleifera L. remains unclear. A susceptibility of this species may lead to increase poverty in endangered regions. M. oleifera is a woody species native from sub-Himalaya regions under high climate stress pressure. The interest on this species is emerging due to its several medicinal properties and its nutritional value. Agropharmaceutical industry is interest in this species too. To understand the impact of increased climate factors, young (2 months old) plants of this species were exposed to water deficit (WD) and UVB (alone or combined). WD and WD+UVB imposition consists of unwater for 4 days. After 1 day withholding water, UVB and WD+UVB were irradiated with 26.3 kJ m-2 distributed per 3 days. Immediately after treatment exposition (1 day) and after 10 days, plant water status, growth, carbon metabolism and oxidative stress were measured. Overall no significant differences were observed in WD, regarding the parameters analysed, except on gas exchanges, MDA and phenols. The plants exposed to UVB showed, in general, more severe effects, as higher pigment content, MDA and membrane permeability, while no changes were observed in the total antioxidant activity. Plants exposed to UVB+WD, despite changes observed, the impact was lower than the one observed in UVB exposed plants, meaning that a protective/adaptive mechanism was developed in the plants under combined stressors. On the other hand, in all treatments the net CO2 assimilation rate decreased. Results suggest that M. oleifera has some tolerance to WD and UVB, and that develops mechanism of adaptation to these two types of stress that often arise in combination under a climate change scenario.
Fatores abióticos extremos, como a seca combinada com ondas de calor e/ou elevada radiação UVB estão previstas tornarem-se mais frequentes no futuro. O impacto na produção agrícola destes desafios em Moringa oleifera L. permanece desconhecido. A suscetibilidade desta espécie pode levar ao aumento da pobreza em regiões em perigo. M. oleifera é uma espécie lenhosa nativa da região abaixo dos Himalaias que se encontra sob alta pressão climática. O interesse nesta espécie é emergente devido às suas várias propriedades medicinais e ao seu valor nutricional. Também a industria agro-farmacêutica está interessada nesta espécie. Para perceber o impacto do aumento dos fatores climáticos, plantas jovens (2 meses) desta espécie foram expostas a défice hídrico (WD) e UVB (sozinho ou combinado). A imposição a WD e a WD+UVB consistiu em não regar durante 4 dias. Após 1 dia sem regar, os tratamentos UVB e WD+UVB foram irradiados com 26.3 kJ m-2 distribuídos por 3 dias. Imediatamente após a exposição ao tratamento (1 dia) e após 10 dias, o estado hídrico da planta, o crescimento, o metabolismo do carbono e o stress oxidativo foram analisados. No geral não foram observadas diferenças em WD, em relação aos parâmetros analisados, exceto nas trocas gasosas, MDA e fenóis. As plantas expostas a UVB mostraram, em geral, efeitos mais severos, como elevado conteúdo em pigmentos, MDA e permeabilidade membranar, enquanto não foram observadas alterações na atividade antioxidante total. Plantas expostas a WD+UVB, apesar das alterações observadas, o impacto foi menor que o observado nas plantas expostas a UVB, significando que um mecanismo de proteção/adaptação foi desenvolvido nas plantas sobre stress combinado. Por outro lado, em todos os tratamentos a taxa de assimilação de CO2 diminuiu. Os resultados sugerem que M. oleifera apresenta alguma tolerância a WD e a UVB, e que desenvolveu um mecanismo de adaptação a estes dois tipos de stress que frequentemente surgem combinados sob um cenário de alterações climáticas.

Abstract (sommario):
Regulating carbon markets in order to fight the effects of climate change has in recent years become an integral part of many economies around the world. Ensuring that policymakers implement market-based climate change legislation according to international best practice is an essential part to guarantee that a carbon market system operates smoothly within a country’s economy. There are many opportunities that exist in South Africa towards developing a lucrative carbon market; however, the information to implement such a system is hard to come by and complex to analyse. This dissertation will aim to shed some light on this relatively new field of the law as it will provide an overview of international best practice within the carbon market sphere. Furthermore, this dissertation will examine the legal nature of a carbon credit; analyse international instruments regulating carbon markets and discuss existing South African policies and legislation related to climate change and carbon markets. This will lead to the ultimate objective of this dissertation: to propose a possible framework for the regulation of a South African carbon market based upon international best practice. This dissertation revealed the imperative need for South African policymakers to implement legislation to conform to international best practice within carbon markets. In this regard the dissertation also revealed that the infrastructure to regulate such a market already exists within South Africa. Only subtle changes to these infrastructure systems will be required in order for to accommodate a functioning carbon market. The study revealed that the only way to convince entities around the world to emit fewer emissions and to contribute towards the fight against climate change is to attach a monetary value to emissions. Associating a price to carbon is the only way to sanction entities that produce emissions and compensate entities that mitigate emissions. A carbon tax coupled with a carbon offset mechanism, as opposed to a emissions trading scheme, would be the best option with regards to establishing a South African carbon policy. This will ensure a fair playing field, as carbon tax liable entities would be held responsible to pay the same fixed price per ton of carbon that they emit. Coupling the carbon tax with a carbon offset mechanism, trading with carbon credits, will incentivise companies to invest in “greener” technologies and to emit fewer emissions. This dissertation revealed that international best practice in the carbon market sphere, still poses significant difficulties such as price volatility associated with carbon credits; validation and verification inconsistencies within the different carbon standards; and supply and demand fluctuations. These difficulties where highlighted in this dissertation and solutions relating to these difficulties were discussed. The time has come for South Africa to enter the carbon market sphere, whether it be through the introduction of a carbon tax or otherwise. This dissertation illustrates that the infrastructure and stakeholders associated to a South African carbon market needs to be developed. If, when and how the government will actually implement such a carbon market system, remains a question to be answered.

Abstract (sommario):
The focus of this study is on understanding the multiple and interacting factors that hinder or enable municipal planned climate change adaptation, here called barriers and enablers respectively, and their implications for community based adaptation. To do this I developed a conceptual framework of barriers to and enablers of planned climate change adaptation, which informed a systematic literature review of barriers to planned community based adaptation in developing countries. In this framework barriers were grouped into resource, social and physical barriers. I then conducted empirical case study analysis using qualitative research methods in four South African municipalities to understand what barriers and enablers manifested in these contexts. In light of the reflexive nature of my methodology, my framework was adjusted based on my empirical findings, where contextual barriers were found to better represent the empirical results and subsumed physical barriers. I found my framework useful for analysis, but in the empirical cases, barriers and enablers overlaid and interacted so significantly that in reality it was often difficult to separate them. A key finding was that enablers tended to be more about the way things are done, as opposed to direct opposites of barriers. Comparison of barriers and enablers across the case studies revealed a number of key themes. Municipalities struggle to implement climate change adaptation and community based adaptation within contexts of significant social, economic and ecological challenges. These contextual barriers, when combined with certain cognitive barriers, lead to reactive responses. Existing municipal systems and structures make it difficult to enable climate change adaptation, which is inherently cross‐sectoral and messy, and especially community based adaptation that is bottom‐up and participatory. Lack of locally applicable knowledge, funding and human resources were found to be significant resource barriers, and were often underlain by social barriers relating to perceptions, norms, discourses and governance challenges. Enablers of engaged officials, operating within enabling organisational environments and drawing on partnerships and networks, were able to overcome or circumvent these barriers. When these enablers coincided with windows of opportunity that increased the prioritisation of climate change within the municipality, projects with ancillary benefits were often implemented. Analysis of the barriers and enablers identified in the literature and case studies, informed discussion on whether municipalities are able to implement community based adaptation as defined in the literature, as well as the development of recommendations for how municipal planned climate change adaptation and community based adaptation can be further understood and enabled in the future. These recommendations for practice and research include: (a) To acknowledge and understand the conceptual framings of municipal climate change work, as these framings inform the climate change agenda that is pursued, and hence what municipal climate change adaptation work is done and how it was done. (b) The need for further research into the social barriers that influence the vital enablers of engaged officials, enabling organisational environments, and partnerships and networks. (c) To learn from pilot community‐level interventions that have been implemented by municipalities, as well as from other disciplines and municipalities. (d) To develop top‐down/bottom‐up approaches to enable municipal planned climate change adaptation and community based adaptation, that benefits from high level support and guidance, as well as local level flexibility and learning‐by‐doing. (e) To develop viable mechanisms for municipalities to better engage with the communities they serve.

Abstract (sommario):
<p>Climate change could heavily affect climatic actions on structures. Indeed, the current definition of climatic actions in structural codes, snow wind thermal and icing loads, is based on the assumption of stationary climate conditions but climate is not stationary and the observed accelerated rate of changes must be considered. A proper evaluation of the consequences of climate change requires the set-up of procedures able to deal with the analysis of climate projections and their intrinsic uncertainties.In the paper, a general methodology is illustrated, aiming to evaluate the impact of climate change on structural design. The proposed procedure is based on the definition of factors of change for climate extremes in moving time windows derived from the analysis of an ensemble of climate projections according different greenhouse gas emission scenarios, combined with an innovative weather generator to obtain a probabilistic description of future changes.The definition of a suitable envelope of characteristic values, provide guidance for a better estimation of climatic action in structural codes taking into account their evolution with time.</p>

Abstract (sommario):
The last century was characterized by noticeable climatic changes. The whole world, including Ukraine has been significantly impacted. Such changes are characterized by increased average annual temperature on the planet surface, increased level of the water in the oceans, increased number of natural disasters and cataclysms, such as desertification, landslides, hurricanes, etc. Furthermore, the climate change coincides with the period of increasing food shortages in the world. The aim of the article is to study the dependence of agricultural efficiency on the changes in agro-climatic conditions of production in the long term and the impact of these changes on the cultivation of agricultural crops and their productivity. Research methods are general scientific and special, qualitative and quantitative, theoretical and empirical, comparative analysis. Agriculture is the sector of the Ukrainian economy that is the most vulnerable to fluctuations and climate changes. Given its inertial nature and the dependence on weather conditions, it is essential to make timely and adequate decisions regarding the problems caused by climate changes. Taken the expected increase of the air temperature in the Northern Hemisphere, Ukraine's food security will largely depend on the efficient adaptation to upcoming climate changes. The consequences and risks of the climate change for the food production vary from region to region, however the negative impact of climate trends outweighs the positive one. Thus, the research of the impact of climate change on the efficiency of agro-food production is crucial for the development of policies that would help to adapt to the consequences of these changes.

Testo completo
Abstract (sommario):
The present paper uses a methodological and theoretical perspective on cognitive and cross-cultural psychology as it basis. Our research covers an important area: the role of cognition on the human adaptation to global warming. We draw the general hypothesis that human cognition, mediated by culture, can adapt to changes in the environment. However, we believe that accelerated global climatic changes create cognitive vulnerability because culture cannot provide proper knowledge and cognitive tools. We present some results of our fundamental research on cognitive adaptation to climate change from a cross-environmental and cross-cultural perspective. We specifically highlight some preliminary comparative analysis between adults of New Caledonia and Paris on the representation of climate and climate change followed by the human capacity to adapt to this condition. In addition, we provide an intra-cultural comparison on representation of climate, taking into consideration important geographic and climatic differences in France. Preliminary results suggest that culture and environmental experiences have focal impacts on cognitive adaptation. Our findings show that Parisian adults present greater cognitive vulnerability, thus less adaptive cognition. In the light of cross-cultural psychology, we consider that this fact is due, on one hand, to the analytic way of thinking dominated by an urban occidental population and, on the other hand, to the absence of bi-metric representations.

Abstract (sommario):
Whether it is climate fluctuations or lasting one-way changes, it is clear that the climate today is not the same as it was a few decades ago. The question is no longer whether the change of climate exists, but in what way and to what extent it affects nature, man and his activity, how to mitigate it, and how to adapt to it. For this purpose, however, it is necessary to accurately determine the magnitude and direction of change of individual climatic elements and phenomena, given their diverse manifestations at the local level. This is especially true in urban areas, where a large part of the population is concentrated. Here climate change is becoming even more tangible as a result of the highly transformed underlying surface and air pollution. This is why many research on climate change is focusing on big cities. The aim of the present study is to establish the long-term trends of change of basic climatic parameters in the largest city in Bulgaria - the capital Sofia. For this purpose, based on the historical climatic period 1967 - 2019, the algorithms of changing the following climatic elements are determined: air temperature, precipitation, wind speed, number of days with rainfall, with snowfall, with storms, with hail and with fog. Based on the determined algorithms, the values of these climatic elements are projected to future time horizons, in 10 years, until 2100. The results are of interest not only from a purely scientific point of view, but also for all economic sectors experiencing the impact of changing the climate.

Abstract (sommario):
The threat of climate change and its negative consequences is currently a very serious and immediate problem. Undoubtedly, the most striking manifestation of climate change is global warming, both on land and in the oceans. Increasing the average air temperature adversely affects natural ecosystems, which find it very difficult to adapt to this change. Significant consequence of climate change is also the fundamental impact on water resources. In this work we focused on the influence of climatic conditions on the dynamics of walnut tree (Juglans regia L.) in July (2019-2021), when the influence of lack of precipitation on the walnut growth are most critical. We compared dendrometric changes to air temperature and precipitation. For this measurement were used Dendrometers DD-S from Ecomatic at two groups of walnut trees � irrigated and non-irrigated trees. From the results, it is found a significant decrease in precipitation compared to the climate normal, most marked in 2021. A significant difference between irrigated and non-irrigated walnuts is seen in 2019 (3.2 mm) and in 2020 (2.4 mm). In 2021, the difference is only 0.85 mm, which could be due to insufficient irrigation, lack of precipitation, and the quantity of fruit. The impact of climate change and its greatest impact � drought, can be observed throughout the period under review. This research can serve as a basis for drought assessment and will be further developed.

Abstract (sommario):
This paper explores options to minimize threats posed to IDB-financed physical investments by the impacts of climate change. A large proportion of projects are implemented in climate-sensitive sectors (e.g., agriculture, water resources, and transport). In these cases, the norm is to consider historic climatic trends for guiding project conceptualization and design. However, there is growing realization among international development agencies including the IDB that this may not be sufficient; many multilateral and bilateral development agencies now recognize the need to also consider future changes in long-term trends of climatic variables, as well as the possibility of an intensification or increased frequency of extreme climatic events such as floods, droughts, and hurricanes.

Abstract (sommario):
The maps and tables presented here represent potential variability of projected climate change across the conterminous United States during three 30-year periods in this century and emphasizes the importance of evaluating multiple signals of change across large spatial domains. Maps of growing degree days, plant hardiness zones, heat zones, and cumulative drought severity depict the potential for markedly shifting conditions and highlight regions where changes may be multifaceted across these metrics. In addition to the maps, the potential change in these climate variables are summarized in tables according to the seven regions of the fourth National Climate Assessment to provide additional regional context. Viewing these data collectively further emphasizes the potential for novel climatic space under future projections of climate change and signals the wide disparity in these conditions based on relatively near-term human decisions of curtailing (or not) greenhouse gas emissions.

Testo completo
Abstract (sommario):
One of the challenges of climate change in the building sector is related to the durability of materials, i.e., the resistance to degradation due to weathering over time. The durability of building components can be assessed through long-term natural outdoor climate exposure or appropriate accelerated climate aging in the laboratory. SINTEF Research Centre owns a climate simulator apparatus to perform aging tests according to the Nordtest method NT Build 495:2000. The aim of this article is to show the results from an accelerated climatic aging test performed on three different configurations of a structural insulated panel (SIP), which is characterized by waste-based core materials. The samples were tested for one month, corresponding to about one year of natural outdoor climate exposure. The results from the test performed in the climate simulator include information on the sample changes occurring during the analyzed period, together with the scale of such changes and the time of occurrence. Therefore, the test results are qualitative and based on the fact that a change in the performance properties of the samples corresponds to a change in their appearance during the test. This includes, for instance, signs of degradation, such as cracks, loss of gloss, or delamination.

Abstract (sommario):
Lake Arakhley is located within the Lake Baikal basin in Eastern Siberia, Russia. The area is characterized by continental subarctic climate with considerate diurnal temperature range, long cold dry winters and short hot summers with more precipitation occurring during the latter half of the summer. Climatic shifts in high water years and low water years result in morphometric changes in the lake and in the chemical and physical parameters of the ecosystem. During low water years, concentrations of ammonium nitrogen and nitrite nitrogen are decreased, whereas nitrate concentration increases. High water years feature average concentrations of ammonium ions 1.5–2 times higher than the values of recent dry years. Redundancy analysis (RDA) of abiotic factors and biotic community indicated that the community structure shows the greatest correlation with physical and chemical parameters of water and biogenic elements (nitrites, ammonium, phosphates) along the first axis, and with the lake depth and transparency along the second axis. Changes in abiotic factors induce functioning and formation of characteristic communities of the primary producers in the trophic structure of the ecosystem. During low water years, with increased level of autochthonous organic matter, Lindavia comta dominance is observed, while during high water years, with increased allochthonous organic matter Asterionella formosa appeared as dominant. Currently, during low water years, the hydrophytes community is monodominant and composed of Ceratophyllum demersum. Meanwhile, such species indicating eutrophic conditions as Myriophyllum sibiricum, Potamogeton pectinatus are found in the lake vegetation.

Abstract (sommario):
Greenhouse gas emissions caused by human activity have already warmed the climate of Earth by more than one degree. Significant changes have been observed e.g. in the intensity of heatwaves and heavy rainfall. Future climate change depends on human emissions, but it is likely that the global mean temperature still rises by another 1–2 degrees by the end of this century. The ongoing global warming is already visible in the climate of the capital region. Many of the observed changes are consistent with what human-caused intensification of the greenhouse effect will bring. During the past 60 years, the average temperatures have risen in all seasons, but the strongest warming has been observed in winter. Precipitation has increased in the winter season, but no statistically significant trends in precipitation can be observed in other seasons. In addition to the average climatic conditions, heatwaves have intensified with a stronger increase in the inland regions than on the coast. In this report, the latest climate change projections based on CMIP6 climate models and SSP greenhouse gas scenarios used in the IPCC's Sixth Assessment Report are presented. According to the moderate SSP2-4.5 emission scenario, the average temperatures are predicted to rise in the capital region by 2.5–3 degrees in all months from the period 1981–2010 by the period 2040–2069. The warming is slightly weaker than in Finland on average, and the changes are somewhat larger in winter than in summer. A milder winter climate results in a further decrease in snow and ice cover. The rising temperatures in summer bring stronger heatwaves, heavy rainfalls and prolonged periods of droughts. There are no clear signs of change in the windiness, and thus winter storms are not predicted to be notably stronger in the future than they are now. Instead, the amount of precipitation induced by winter cyclones increases and comes more often as rain than snow. The sea level is not projected to rise much by the mid-century, but by the end of the century it is estimated to rise by about 25 cm from its current level. Even according to the most optimistic emission scenario, the climate in the capital region would warm by more than one degree by the 2080s. The climate change by the end of the century experienced by future generations is highly dependent on human emissions, and one must be ready to prepare for some degree of change. On the other hand, the climate in the capital region is subject to significant natural variability, and therefore cold periods of weather may occur also in the future.
