As Arctic Ocean ice disappears, the global climate impacts intensify
2016-09-27 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Yale Environment 360: The news last week that summer ice covering the Arctic Ocean was tied for the second-lowest extent on record is a sobering reminder that the planet is swiftly heading toward a largely ice-free Arctic in the warmer months, possibly as early as 2020. Peter Wadhams, professor emeritus of ocean physics at Cambridge University, is a sea ice specialist with 46 years of research on sea ice and ocean processes in the Arctic and Antarctic. In more than 50 expeditions to both polar regions, he has worked...

Consequences of Climate Change: Polar Bear Population Shrinking Due to Arctic Sea Ice Melt
2016-09-26 04:55:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World: Alert! The melting sea ice in the Arctic is leaving polar bear hungry and their population dwindling in numbers. According to a report from Earth Sky, polar bears have taken the most drastic hit from the melting Arctic sea ice due to climate change. Polar bears mainly get their fat and nutrients from eating seals, and the ice in the Arctic has greatly helped the slow-moving bears to catch the much-faster seals by ambushing the latter through the ice. However, as the Arctic sea ice continues...
Arctic melt shrinks polar bears chances

Climate News Network: The world of the polar bear is shrinking everywhere. New research by scientists in the US confirms that each of the 19 known populations of Ursus maritimus is increasingly affected by the earlier sea ice melt in the Arctic spring, and the later arrival of ice every autumn. The finding is hardly a shock, as there have been warnings from conservationists about such things for years, with the polar bear becoming an icon of climate change concerns. And in most cases of species threat there are winners...

Arctic nations square up as clamour for resources grows
2016-09-18 01:05:00| Climate Ark Climate Change & Global Warming Newsfeed
Guardian: Kristian Jensen, Denmarks foreign minister, gave a precise response last week to a request by Russia for the nations to enter bilateral talks over the ownership of the north pole. He flatly rejected the move. We need to apply the international rules, he told reporters. The Russian request and the swift Danish response are intriguing. The United Nations is currently assessing Russian, Danish and Canadian claims to own sizeable chunks of the Arctic seabed. The Russian move was generally viewed...

Sea ice in Arctic shrinks to second lowest level on record
2016-09-17 15:11:00| Climate Ark Climate Change & Global Warming Newsfeed
Associated Press: Arctic sea ice this summer shrank to its second lowest level since scientists started to monitor it by satellite, with scientists saying it is another ominous signal of global warming. The National Snow and Ice Data Center in Colorado said the sea ice reached its summer low point on Saturday, extending 1.6 million square miles (4.14 million square kilometers). Thats behind only the mark set in 2012, 1.31 million square miles (3.39 million square kilometers). Center director Mark Serreze said...
