Arctic faces further threat from ocean acidification
2013-05-07 11:58:00| Climate Ark Climate Change & Global Warming Newsfeed
Reuters: The Arctic ecosystem, already under pressure from record ice melts, faces another potential threat in the form of rapid acidification of the ocean, according to an international study published on Monday. Acidification, blamed on the transformation of rising levels of the greenhouse gas carbon dioxide from the air into carbonic acid in the sea, makes it harder for shellfish and crabs to grow their shells, and might also impair fish reproduction, it said. Cold water absorbs carbon dioxide more...

Mercury link to Arctic fox decline
2013-05-06 23:01:00| Climate Ark Climate Change & Global Warming Newsfeed
BBC: Scientists say that foxes in Arctic regions who feed on ocean prey are being exposed to dangerous levels of mercury. On one Russian island where the population of foxes has crashed, the researchers believe the toxin has played a key role in the decline. They say the findings could have important implications for conservation. The data is published in the Journal, PLOS ONE. Mercury levels in the world's oceans have doubled over the past 100 years, according to the UN, with more mercury...

With Arctic sea ice vulnerable, summer melt season begins briskly
2013-05-02 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Christian Scienc Monitor: After a record loss of summer sea ice in the Arctic Ocean last year, the 2013 melt season has begun at the top of the world, with ice vanishing in April at a faster pace than it did this time last year. Summer sea ice a key player in Earth's climate system and one whose decline is widely taken as a prominent sign of global warming has been shrinking in extent since satellites first started to build a consistent record of the ice in late 1978. Ice losses in 2007 set a melt-season record, only...
White House warned on imminent Arctic ice death spiral
2013-05-02 15:30:00| Climate Ark Climate Change & Global Warming Newsfeed
Guardian: Senior US government officials are to be briefed at the White House this week on the danger of an ice-free Arctic in the summer within two years. The meeting is bringing together Nasa's acting chief scientist, Gale Allen, the director of the US National Science Foundation, Cora Marett, as well as representatives from the US Department of Homeland Security and the Pentagon. This is the latest indication that US officials are increasingly concerned about the international and domestic security...
