Climate change threatens Arctic food security and culture
2014-10-09 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Al Jazeera: Its increasingly difficult to find food using traditional hunting methods in the Arctic, and at the same time, provisions sold at stores are unaffordable for many, jeopardizing food security and cultural life in the region, Arctic experts and residents said, responding to a United Nations report released Monday that highlights the impact of climate change on Arctic communities. Everything from ice-dependent algae to marine mammals to humans relying on sea ice for food and economic opportunities...

Canadian Environment Commissioner Takes Aim at Arctic, Oil Sands

Toronto Star: The Federal government isnt doing enough to combat climate change or to reduce pollution from Albertas oilsands, says a scathing new report by the environment commissioner. But environment commissioner Julie Gelfands most biting remarks are on the governments lack of preparation for increasing marine traffic in the Arctic. She warns there are outdated maps and surveys, inadequate navigational aids and icebreaking services that are stretched to the limit. The six-chapter report is her first...

Arctic ice shrinks as Antarctic ice expands
2014-10-08 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Australian Broadcasting Corporation: CHRIS UHLMANN: As Australians prepare for a long hot summer it's fair to say that not many of us are pondering the extent of sea ice in the Arctic. But scientists say we should be. The extent of the ice melt is both an important barometer and a cause of climate change. The latest satellite data shows the big melt has set in and that means big consequences for everything from walruses to the gases trapped by the permafrost. At the same time, ice closer to home in the Antarctic is growing but...

The truth about Arctic sea ice melt, and its inevitable denial
2014-10-07 20:49:00| Climate Ark Climate Change & Global Warming Newsfeed
Grist: First, the truth: After a summer of seasonal melting, on Sept. 17, 2014, Arctic sea-ice extent* likely hit its minimum for the year. The official word is that it was measured at 5.02 million square kilometers (1.94 million square miles). This is the sixth-lowest minimum since satellite records began in 1979. It also fits right in with the overall declining trend of Arctic sea ice: As you can see, back in the late 70s there used to be about 7.5 million square kilometers when ice hit its...

Climate change adversely affecting Arctic wildlife
2014-10-07 18:45:00| Climate Ark Climate Change & Global Warming Newsfeed
Alaska Dispatch: There is increasing evidence that climate change, which is warming the polar region, is having a negative affect upon a variety of wildlife. While there have long been concerns that some populations of polar bears are shrinking, studies now show that polar bears, as a species, are also shrinking in size. The bears need ice to hunt, mostly seals, but less ice in recent years has meant less hunting, and thus the shrinking size. Scientists say the female bears typically weigh 650 pounds, but...
