Sex Of Turtles Changing As Climate Change Warms Planet

2013-05-07 15:07:00| Climate Ark Climate Change & Global Warming Newsfeed

Huffington Post: If you're a male painted turtle, global warming might sound great at first: A new study suggests it will mean more females to mate with and fewer male rivals to fend off. But, as usual with climate change, every silver lining has a cloud. In this case, too many females could render the species incapable of reproducing by century's end. Painted turtles (Chrysemys picta) live in freshwater habitats across North America, where the sex of their unhatched young is determined by ambient temperature....

Climate zones will shift faster as world warms

2013-04-23 10:00:00| Climate Ark Climate Change & Global Warming Newsfeed

Nature: Earth's regional climate zones will shift more quickly in response to warming as the globe grows hotter in coming decades, according to a study published online in Nature Climate Change on Sunday1. This is likely to make it harder for species to cope, raising the risk of extinction. If these changes are happening faster and faster, it means that the ecosystems have less and less time to adapt, says Irina Mahlstein, a postdoctoral researcher at the Cooperative Institute for Research in Environmental...

Millions face starvation as world warms, say scientists

Guardian: Millions of people could become destitute in Africa and Asia as staple foods more than double in price by 2050 as a result of extreme temperatures, floods and droughts that will transform the way the world farms. As food experts gather at two major conferences to discuss how to feed the nine billion people expected to be alive in 2050, leading scientists have told the Observer that food insecurity risks turning parts of Africa into permanent disaster areas. Rising temperatures will also have a...

Antarctic ice grows as climate warms

2013-04-03 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed

New Scientist: Call it a tale of two poles. While sea ice in the Arctic is vanishing fast, the extent of Antarctic ice has increased. Good explanations for the growth of ice in the Southern Ocean have been hard to find, but now the problem may have been cracked. Counter-intuitively, it seems global warming may be cooling southern surface waters. Nobody predicted that the fate of ice at each pole would take such different paths in just 30 years, with Arctic sea ice dropping more than 15 per cent, even as Antarctic...

Canada: Thomson: Wildrose Party warms up to climate change

2013-03-28 01:18:00| Climate Ark Climate Change & Global Warming Newsfeed

Edmonton Journal: You probably didnt feel the earth move but a seismic shift has taken place in Alberta politics. The Wildrose Party now acknowledges the matter is settled on the issue of human-induced climate change. That revelation might not rock your world but it probably sent a shiver up the spines of those who still stubbornly deny the realities of the science and who view the Wildrose as their champion. That science is absolutely settled, Wildrose MLA Rob Anderson said in the legislature last week....
