The article covers the specifics of land development and construction in the Arctic North. This requires the effective use of climate information to select optimal solutions for preventing unjustified overpricing of facilities, increased heat loss, low thermal resistance, and durability, affecting the overspending of capital investments. Recent trends in dynamic climate change leading to rising global sea levels, which could flood coastal areas of the Arctic seas, are considered. This can come along with the destruction of the coastal area and pose a great danger to infrastructure facilities.

AbstractThis review analyses the scarce available data on biodiversity and transmission of helminths in Arctic coastal ecosystems and the potential impact of climate changes on them. The focus is on the helminths of seabirds, dominant parasites in coastal ecosystems. Their fauna in the Arctic is depauperate because of the lack of suitable intermediate hosts and unfavourable conditions for species with free-living larvae. An increasing proportion of crustaceans in the diet of Arctic seabirds would result in a higher infection intensity of cestodes and acanthocephalans, and may also promote the infection of seabirds with non-specific helminths. In this way, the latter may find favourable conditions for colonization of new hosts. Climate changes may alter the composition of the helminth fauna, their infection levels in hosts and ways of transmission in coastal communities. Immigration of boreal invertebrates and fish into Arctic seas may allow the circulation of helminths using them as intermediate hosts. Changing migratory routes of animals would alter the distribution of their parasites, facilitating, in particular, their trans-Arctic transfer. Prolongation of the seasonal ‘transmission window’ may increase the parasitic load on host populations. Changes in Arctic marine food webs would have an overriding influence on the helminths’ circulation. This process may be influenced by the predicted decreased of salinity in Arctic seas, increased storm activity, coastal erosion, ocean acidification, decline of Arctic ice, etc. Greater parasitological research efforts are needed to assess the influence of factors related to Arctic climate change on the transmission of helminths.

There is no doubt that the cryosphere is changing, the planet's temperature is increasing and ice is retreating. Earth is gradually experiencing the repercussions of global warming which are most visible at high latitudes, and especially in the Arctic, the home of Odobenus Rosmarus or simply Walrus. The walrus is one of the most ice-dependent species. Walruses use sea ice for crucial behaviours like giving birth, feeding and resting. As the seasonal dynamics of ice cover on arctic seas change, walruses tend to congregate on coasts without ice. Thanks to this adaptation of walruses to different climate trends they have successfully survived and conserved their populations. Its adaptability has been the driving force behind preventing the walrus from being listed as an endangered species. Some scientists are attributing this trend to a normal adaptive behaviour of the mammal, while others already have noticed a risk violently posed by climate change. This article is motivated by the announcement of the U.S. Fish and Wildlife Service that the walruses were unlikely to be considered endangered in the foreseeable future, addresses the vulnerability of walruses to climate change, explaining their dependence on sea ice and the need for reconsideration of the above statement.

ABSTRACTMaritime traffic is increasing in Arctic seas in the context of climate change. The rapid melting of sea ice led to the widespread belief that traffic was set to expand rapidly, challenging Canadian and Russian-claimed sovereignties over their respective Arctic passage, and underlining the risk posed by such a traffic in a risky but fragile environment. If projections on potential traffic for the medium term are probably exaggerated, the increasing traffic nevertheless challenges the adequacy of the regulatory framework.

The article reflects the specifics of land development and construction in the Arctic North. It is necessary to use climate information effectively to select the best solutions and to avoid undue overestimation of the cost of facilities, increased heat loss, low heat resistance and strength affecting overspending. Recent trends in the context of dynamic climate change leading to rising sea levels, and possible flooding of coastal areas of the Arctic Seas are considered in this paper. The authors underline a great danger to infrastructure in result of possible destruction of coastal areas.

Contemporary challenges and threats to sustainable development including safe use of transboundary resources of rivers and Arctic seas in condition of climate change are connected with cumulative impact of numerous factors. Ongoing environmental changes have transboundary nature and will have significant impact in international scale. In case of overlapping of factors of impact their nature and synergetic effect, mechanisms of their interrelated influence and possible negative consequences for global economy, environment and human health are not adequately known. Among the main obstacles to mitigation of climate change impact on the state of big river basins in the Arctic and Arctic seas are: the lack of critically important information and data, absence of modern concepts of climate change mitigation measures connected with impact on Arctic seas, uncoordinated and inefficient regulation and management, absence of unified interstate tools of marine spatial planning. The article contains the analysis of risks and global consequences of the ongoing climate change for water resources; characteristic of priority issues and their underlying root causes. It also contains the results of the analysis of risks connected with melting of permafrost and increase in thermal coast erosion, assessment of the role of transboundary cooperation in the Arctic for sustainable regional development. The authors also propose some measures for addressing the above issues based on the Strategic Program of Actions on the Protection of the Russian Part of the Arctic developed by the Ministry of Economic Development of Russia.
