Global climate change in the Arctic has been unfolding more rapidly than in other parts of the world, and its impacts affect vulnerable northern ecosystems, health and well-being of the Northerners, economic sectors and infrastructure in the polar regions of the eight Arctic states. Consequences of climate change for human society are analysed in synergy with ongoing transformations in social, economic and institutional systems in the Arctic region. Their cumulative effect exposes a variety of challenges for sustainable development of the northern communities, regions and countries; it reveals a number of uncertainties in the future pathways within the transformative context, as well as a combination of risks and opportunities for societies; it requires human responses and adaptations to consequences of the Arctic change. Adaptation to climate change in combination with greenhouse gases emission reduction turns into an important component of climate policies and measures of the Arctic states. This article presents innovative results of analysis of the major trends and features in formation of adaptive governance in the Arctic. It emerges to be based on a polycentric design, and particularly, on coordination of response actions at various levels, on interactions and networks of a variety of the Arctic stakeholders, on taking into account local environmental and socio-economic contexts, on combination of multidisciplinary approaches and packaging of governance mechanisms and instruments. The study analyses the major developments and innovations in adaptation approaches, policies, and practices of the Arctic regions in N. America (Canada) and Europe (Norway). Its foci is on assessment of priorities, strategies and planning, institutions, economic instruments, climate services, application of structural measures for disaster risk reduction. It explores possibilities of regional exchange of best practices in the Arctic, and core barriers for success in implementation of adaptation policy options. The role of the Paris agreement in formation and structuring of adaptation policies and measure of the northern regions of the Arctic states is analysed.

Sea ice concentration (SIC) plays a significant role in climate change research and ship’s navigation in polar regions. Satellite-based SIC products have become increasingly abundant in recent years; however, the uncertainty of these products still exists and needs to be further investigated. To comprehensively evaluate the consistency of the SIC derived from different SIC algorithms in long time series and the whole polar regions, we compared four passive microwave (PM) satellite SIC products with the ERA-Interim sea ice fraction dataset during the period of 2015–2018. The PM SIC products include the SSMIS/ASI, AMSR2/BT, the Chinese FY3B/NT2, and FY3C/NT2. The results show that the remotely sensed SIC products derived from different SIC algorithms are generally in good consistency. The spatial and temporal distribution of discrepancy among satellite SIC products for both Arctic and Antarctic regions are also observed. The most noticeable difference for all the four SIC products mostly occurs in summer and at the marginal ice zone, indicating that large uncertainties exist in satellite SIC products in such period and areas. The SSMIS/ASI and AMSR2/BT show relatively better consistency with ERA-Interim in the Arctic and Antarctic, respectively, but they exhibit opposite bias (dry/wet) relative to the ERA-Interim data. The sea ice extent (SIE) and sea ice area (SIA) derived from PM and ERA-Interim SIC were also compared. It is found that the difference of PM SIE and SIA varies seasonally, which is in line with that of PM SIC, and the discrepancy between PM and ERA-Interim data is larger in Arctic than in Antarctic. We also noticed that different algorithms have different performances in different regions and periods; therefore, the hybrid of multiple algorithms is a promising way to improve the accuracy of SIC retrievals. It is expected that our findings can contribute to improving the satellite SIC algorithms and thus promote the application of these useful products in global climate change studies.

A rigorous synthesis of the sea-ice ecosystem and linked ecosystem services highlights that the sea-ice ecosystem supports all 4 ecosystem service categories, that sea-ice ecosystems meet the criteria for ecologically or biologically significant marine areas, that global emissions driving climate change are directly linked to the demise of sea-ice ecosystems and its ecosystem services, and that the sea-ice ecosystem deserves specific attention in the evaluation of marine protected area planning. The synthesis outlines (1) supporting services, provided in form of habitat, including feeding grounds and nurseries for microbes, meiofauna, fish, birds and mammals (particularly the key species Arctic cod, Boreogadus saida, and Antarctic krill, Euphausia superba, which are tightly linked to the sea-ice ecosystem and transfer carbon from sea-ice primary producers to higher trophic level fish, mammal species and humans); (2) provisioning services through harvesting and medicinal and genetic resources; (3) cultural services through Indigenous and local knowledge systems, cultural identity and spirituality, and via cultural activities, tourism and research; (4) (climate) regulating services through light regulation, the production of biogenic aerosols, halogen oxidation and the release or uptake of greenhouse gases, for example, carbon dioxide. The ongoing changes in the polar regions have strong impacts on sea-ice ecosystems and associated ecosystem services. While the response of sea-ice–associated primary production to environmental change is regionally variable, the effect on ice-associated mammals and birds is predominantly negative, subsequently impacting human harvesting and cultural services in both polar regions. Conservation can help protect some species and functions. However, the key mitigation measure that can slow the transition to a strictly seasonal ice cover in the Arctic Ocean, reduce the overall loss of sea-ice habitats from the ocean, and thus preserve the unique ecosystem services provided by sea ice and their contributions to human well-being is a reduction in carbon emissions.

The Impact

<p>The polar regions exhibit some of the most visible signs of climate change globally; annual mass loss from the Greenland Ice Sheet (GrIS) has quadrupled in recent decades, from 51 ± 65 Gt yr<sup>−1</sup> (1992-2001) to 211 ± 37 Gt yr<sup>−1</sup> (2002-2011). This can partly be attributed to the widespread retreat and speed-up of marine-terminating glaciers. The Zachariae Isstrøm (ZI) is an outlet glacier of the Northeast Greenland Ice Steam (NEGIS), one of the largest ice streams of the GrIS (700km), draining approximately 12% of the ice sheet interior. Observations show that the ZI began accelerating in 2000, resulting in the collapse of the floating ice shelf between 2002 and 2003. By 2014, the ice shelf extended over an area of 52km<sup>2</sup>, a 95% decrease in area since 2002, where it extended over 1040km<sup>2</sup>. Paleo-reconstructions provide an opportunity to extend observational records in order to understand the oceanic and climatic processes governing the position of the grounding zone of marine terminating glaciers and the extent of floating ice shelves. Such datasets are thus necessary if we are to constrain the impact of future climate change projections on the Arctic cryosphere.</p><p>A multi-proxy approach, involving grain size, geochemical, foraminiferal and sedimentary analysis was applied to marine sediment core DA17-NG-ST8-92G, collected offshore of the ZI, on  the Northeast Greenland Shelf. The aim was to reconstruct changes in the extent of the ZI and the palaeoceanographic conditions throughout the Early to Mid Holocene (c.a. 12,500-5,000 cal. yrs. BP). Evidence from the analysis of these datasets indicates that whilst there has been no grounded ice at the site over the last 12,500 years, the ice shelf of the ZI extended as a floating ice shelf over the site between 12,500 and 9,200 cal. yrs. BP, with the grounding line further inland from our study site. This was followed by a retreat in the ice shelf extent during the Holocene Thermal Maximum; this was likely to have been governed, in part, by basal melting driven by Atlantic Water (AW) recirculated from Svalbard or from the Arctic Ocean. Evidence from benthic foraminifera suggest that there was a shift from the dominance of AW to Polar Water at around 7,500 cal. yrs. BP, although the ice shelf did not expand again despite of this cooling of subsurface waters.</p>

<p>Resiliency and adaptation are increasingly prevalent in climate change policy as well as scholarship, yet scholars have brought forward several critiques of these concepts along analytical as well as political lines. Pressing questions include: who resiliency is for, what it takes to maintain it, and the scale at which it takes place. The concept of "perverse resilience", for example, proposes that resiliency for one sub-system may threaten the well-being of the overall system. In this article, I propose the related concept of "perverse adaptation", where one actor or institution's adaptation to climate change in fact produces aftershocks and secondary impacts upon other groups. Drawing on ethnographic and sociolinguistic research in northern Arizona regarding artificial snowmaking at a ski resort on a sacred mountain, I elucidate resort supporters' and others' attempts to frame snowmaking as a sustainable adaptation to drought (and, implicitly, climate change). I counterpoise these framings with narratives from local activists as well as Diné (Navajo) individuals regarding the significant impacts of snowmaking on water supply and quality, sacred lands and ceremony, public health, and, ironically, carbon emissions. In so doing, I argue that we must interrogate resilience policies for their unexpected "victims of adaptation."</p><p><strong>Key words: </strong>climate change policy, adaptation, perverse resilience, sacred sites, Diné (Navajo)</p>

Potato Yields

The contribution of potatoes to the global food supply is increasing—consumption more than doubled in developing countries between 1960 and 2005. Understanding climate change impacts on global potato yields is therefore important for future food security. Analyses of climate change impacts on potato compared to other major crops are rare, especially at the global scale. Of two global gridded potato modeling studies published at the time of this analysis, one simulated the impacts of temperature increases on potential potato yields; the other did not simulate the impacts of farmer adaptation to climate change, which may offset negative climate change impacts on yield. These studies may therefore overestimate negative climate change impacts on yields as they do not simultaneously include CO2 fertilisation and adaptation to climate change. Here we simulate the abiotic impacts of climate change on potato to 2050 using the GLAM crop model and the ISI-MIP ensemble of global climate models. Simulations include adaptations to climate change through varying planting windows and varieties and CO2 fertilisation, unlike previous global potato modeling studies. Results show significant skill in reproducing observed national scale yields in Europe. Elsewhere, correlations are generally positive but low, primarily due to poor relationships between national scale observed yields and climate. Future climate simulations including adaptation to climate change through changing planting windows and crop varieties show that yields are expected to increase in most cases as a result of longer growing seasons and CO2 fertilisation. Average global yield increases range from 9 to 20% when including adaptation. The global average yield benefits of adaptation to climate change range from 10 to 17% across climate models. Potato agriculture is associated with lower green house gas emissions relative to other major crops and therefore can be seen as a climate smart option given projected yield increases with adaptation.

Human Society

Over the past several decades there has been a strong intensifying trend of human society impact on ecosystems, consumption of natural resources and global change. The environmental impact of the society is fully apparent and dominantly implemented through various greenhouse gases emissions (GHG), leading towards global climate change with considerably spread harmful effects. Global climate change includes the earth and ocean surface and atmospheric warming, but also melting of snow and ice, increase of sea levels and ocean acidity, as well as ever more common natural phenomena extremes (winds, various forms of rainfall/precipitation, extremely low or high temperatures, etc.). Scientists are well-familiarized with the fact that use of fossil fuels, such as oil derivatives and coal, is the main generator of harmful gases. In addition, possible substitutions for fossil fuels in the form of other energy sources are very limited, and it should be remembered that other energy sources also have certain adverse environmental effects. Bearing in mind climate change caused by products of fossil fuels combustion, as well as inevitable depletion of natural crude oil resources, management of growing global energy demand becomes one of the key goals and challenges of 21st century. If these reasons are coupled with obligations emanating from Kyoto Protocol, it is clear that attention of researches should be more than reasonably focused on the main determinants of energy consumption. This study is focused on illumination of key demographic and economic determinants of energy consumption in 28 EU member states in the period 1960- 2014. The results obtained demonstrate that population positively and quite strongly influence total energy consumption. An increase of population of 1% will result in an increase of energy consumption of 1.59% to 1.76%. Such relation most probably can be explained by the fact that demographic growth of the society aggravates and complicates planning processes of efficient energy consumption, diminishing the ability of society to be energy efficient. The population effect of persons aged 65 and above to energy consumption is also positive. An increase in share of this age group of 1% will result in an increase in energy consumption of approximately 0.43%. Positive elasticity coefficient should be understood as a proof that European societies with higher share of senior citizens consume more energy that societies with higher share of younger population, not necessarily as an argument that senior citizens use more energy than younger population. The explanation for such nature of a cause-andeffect relation could be that high share of senior citizens influences the structure of production and consumption, spatial distribution of population, transport infrastructure and social services provided. A significant influence on energy consumption in the EU is made by the level of economic development of countries, which is in accordance with the Environmental Kuznets Curve (EKC), suggesting a relation of inverted letter ?U?. The amount of income per capita needed to have the EKC expressed ranges between 54,183 and 81,552 dollars.

Abstract This essay explores the multiple ways in which the nexuses between water scarcity and climate change are socially and historically grounded in ordinary people's lived experiences and are embedded in specific fields of power. Here we specifically delineate four critical dimensions in which the water crises confronting the African continent in an age of climate change are clearly expressed: the increasing scarcity, privatization, and commodification of water in urban centers; the impact of large dams on the countryside; the health consequences of water shortages and how they, in turn, affect other aspects of people's experiences, sociopolitical dynamics, and well-being, broadly conceived; and water governance and the politics of water at the local, national, and transnational levels. These overarching themes form the collective basis for the host of essays in this volume that provide rich accounts of conflicts and struggles over water use and how these tensions have been mitigated.

Abstract. From the French National Adaptation to Climate Change Plan, the "Drias, les futurs du climat" service has been developed to provide easy access to French regional climate projections. This is a major step for the implementation of French Climate Services. The usefulness of this service for the end-users and decision makers involved with adaptation planning at a local scale is investigated. As such, the VIADUC project is: to evaluate and enhance Drias, as well as to imagine future development in support of adaptation. Climate scientists work together with end-users and a service designer. The designer's role is to propose an innovative approach based on the interaction between scientists and citizens. The chosen end-users are three Natural Regional Parks located in the South West of France. The latter parks are administrative entities which gather municipalities having a common natural and cultural heritage. They are also rural areas in which specific economic activities take place, and therefore are concerned and involved in both protecting their environment and setting-up sustainable economic development. The first year of the project has been dedicated to investigation including the questioning of relevant representatives. Three key local economic sectors have been selected: i.e. forestry, pastoral farming and building activities. Working groups were composed of technicians, administrative and maintenance staff, policy makers and climate researchers. The sectors' needs for climate information have been assessed. The lessons learned led to actions which are presented hereinafter.

&lt;p&gt;Climate change in the Arctic is noticeable and affecting the well-being of the population. The health and emotional state, food and water availability, livelihoods are on the threat. The towns are particularly sensitive to climate change. Their population and infrastructure density is exceptionally high, and temperature fluctuations, as well as extreme weather events, have an exceptionally strong impact on air and water quality, health and other components of human well-being. At the same time, urban communities in the Arctic, especially in industrial development zones, represent a little-studied area in this case.&lt;/p&gt;&lt;p&gt;The report presents the interdisciplinary study results concerning the climate change consequences for the population of Russian Arctic industrial developed areas. The study carried out in Murmansk Region which is a highly industrial and highly urbanized region that is completely included in the Arctic zone of the Russian Federation. Qualitative methods were used; in-depth (more than 50 questions) interviews were conducted with residents of several towns in the region. The study showed corresponds between the subjective perceptions of climate change by urban residents of the Murmansk Region with objective data on meteorological parameters changes. The surveyed urban residents feel changes in health and environmental management practices, and many respondents associate these changes with climate fluctuations. Such a phenomenon as the destruction of infrastructure (residential, public and industrial buildings, roads, energy infrastructure) due to climate change has not been identified. Concerns have been raised about the potential impact of climate warming on the ability to have a decent job due to reduced employment in some industries (such as energy).&lt;/p&gt;&lt;p&gt;The results obtained contribute to a better understanding of the social consequences of climate change in the Russian Arctic. This is important for adaptation actions development.&lt;/p&gt;&lt;p&gt;&amp;#160;&lt;/p&gt;
