It’s a pervasive image, and you can’t help but feel an overbearing sense of guilt or pity for the animal when you see it. The Arctic is warming more quickly than almost any other region on Earth as a result of climate change. In summer, the permafrost soils thaw extensively and they don't completely refreeze in winter, which means that the lakes' shores become unstable and collapse, causing water to drain from the lakes. The planet's average surface temperature has risen about 2.05 degrees Fahrenheit (1.14 degrees... Warming Ocean. In turn, predators (such as foxes or birds of prey) and human communities that depend on these animals would be affected. More... Arctic warming and its consequences have worldwide implications. Because of climate change, that ground is now thawing. FACT: Carbon dioxide, a byproduct of fossil-fuel combustion, is a greenhouse gas, which traps solar radiation in the atmosphere. However, this image shouldn’t symbolize an insurmountable challenge or a lack of hope. The research points to different responses of Arctic animals to climate change … But they hadn't expected it to happen on this scale. More On . Animals in the Arctic, including reindeer and golden eagles, are migrating earlier due to climate change, say researchers who have gathered a huge amount of data to study the behaviour of … This Digest is a faithful summary of the leading scientific consensus report produced in 2004 by the Arctic Climate Impact Assessment (ACIA): "Impacts of a Warming Arctic: Arctic Climate Impact Assessment " Learn more... 1.1 The world’s climate is changing. The melting of the permafrost layer poses significant engineering challenges for roads, buildings, pipelines, and industrial facilities. The information you enter will appear in your e-mail message and is not retained by Phys.org in any form. “The Arctic is showing more extreme indications of climate change,” … For several years, permafrost regions have been thawing more and more intensively in North America, Scandinavia and Siberia—e.g. Thank you for taking your time to send in your valued opinion to Science X editors. However, abrupt and unexpected changes cannot be ruled out. Animal species’ diversity, ranges, and distribution will change. This week, new research confirms that a new Arctic climate system is, indeed, emerging. This summary was prepared in collaboration with the, Impacts of a Warming Arctic: Arctic Climate Impact Assessment, 1. Without urgent action to cut greenhouse gas emissions, the world will continue to feel the effects of a warming Arctic: rising sea levels, changes in climate and precipitation patterns, increasing severe weather events, and loss of fish stocks, birds and marine mammals. Context - Our climate is already changing, particularly in the Arctic where permafrost is melting, glaciers are receding, and sea ice is disappearing. Still on the fence about how much the planet is warming and how much of it is caused by humans? How is the climate changing in the Arctic?

The Arctic Climate Impact Assessment (ACIA) focuses on four sub-regions and considers a series of key impacts: Sub-region I: From East-Greenland to Northwest Russia, Sub-region III: From Chukotka to the Western Canadian Arctic, Sub-region IV: Central and East Canadian Arctic and West-Greenland. More... Arctic climate is now warming rapidly and much larger changes are projected. More... 6.2 Reduced sea ice is very likely to increase marine transport and access to resources. More... 1.2 The Arctic region is the area around the North Pole, essentially an ocean surrounded by land. Methane discharges are cracking open the permafrost in the Arctic, a scientific expedition has revealed. The Arctic Climate Impact Assessment (ACIA) represents the first effort to comprehensively examine climate change and its impacts in the Arctic region, bringing together the findings of hundreds of scientists and the insights of indigenous people. There have been over 200 studies addressing the impacts on 86 species of animals that call the Arctic … International Polar Foundation. However, because of the complexity of the Earth’s climatic system, major surprises are possible if climate evolves differently. March 19, 2018. A global 2018 study published in the journal Science showed that every ecosystem on Earth could face a dramatic shift if climate change continues unabated. Recent reviews suggest that Arctic climate change may be occurring at a rate that is greater than that projected by global climate models (AMAP, 2017a; WMO, 2017). In between, there is a wide expanse of tundra. In a way, we caught a glimpse of the future. However, problems caused by insects, diseases, and weeds are likely to worsen. Climate change in the Arctic Earth's northernmost regions are a global warming hotspot, with some areas experiencing up to three times the warming of the rest of the world, Casas-Prat said. Changes in the Arctic will not only affect local people and ecosystems but also the rest of the world, because the Arctic plays a special role in global climate. Arctic … The ability of the Arctic populations to cope with the impacts of climate change will be greatly affected by political, legal, and socioeconomic factors such as growing populations, urbanization, or self-determination movements. Arctic ecosystem changes will have an impact on a global scale, notably by affecting migratory species’ summer breeding and feeding grounds. and Terms of Use. 3. Your feedback will go directly to Science X editors. *1 Most of the warming observed in the past 50 years is attributed to human activities and particularly to the burning of fossil fuels. You can unsubscribe at any time and we'll never share your details to third parties. What changes are expected in specific areas of the Arctic? In fact, the extra warming may actually contribute to other processes also speeding up Arctic climate change. By combining all our scientific knowledge of natural (solar, volcanic, aerosols and ozone) and human-made (greenhouse gases and land-use changes) factors warming and cooling the climate … More... 5.5 Freshwater ecosystems, such as rivers, lakes, and wetlands are home to a variety of animals. in the extreme northwest of Alaska. The range of results from climate model hindcasts and projections, and observational limitations, add quantitative uncertainty in prediction of future Arctic climate … Here are the facts you need. 3.5 Access to Arctic resources is likely to be affected by climate change, including: wildlife, such as whales, seals, birds, and fish sold on world markets; and oil, gas and mineral reserves. But above all, it shows that extreme events won't occur only at the end of the century, but are already taking place and will do so in the years to come." Published under the authority of the GreenFacts Scientific Board. More... 3.2 The melting of Arctic ice and increased regional precipitation can add freshwater to the oceans, and potentially affect ocean currents in the North Atlantic. Climate change, pollution, and growing resource use are factors that put an increasing pressure on fragile Arctic populations and ecosystems. For their study, Nitze and his colleagues evaluated satellite images of the region surrounding Kotzebue and northwestern Alaska. American Association for the Advancement of Science\"The scientific evidence is clear: global climate change caused by human activities is occurring now, and it is a growing threat to society.\" (2006)3 2.
