Australian Broadcasting Corporation: Climate change Large regions of the planet's permafrost could be vulnerable to thawing if the average global temperature rises just 1.5 degrees more, a new analysis of stalactites and stalagmites in Siberian caves suggests. With climate projections currently suggesting the global climate could warm by more than 2°C over the next century, the new results highlight concerns about the potential for permafrost thawing to amplify climate change by releasing carbon dioxide and methane into the atmosphere....

Icy Siberian caves show tiny warming, may mean big thaw

Reuters: Ancient records from icy caves in Siberia show that a small amount of global warming can thaw vast areas of frozen ground and release harmful stores of greenhouse gases, a study showed. Any melt of permafrost, or permanently frozen soil that covers almost a quarter of the northern hemisphere from Alaska to China, can also destabilize everything from oil and gas pipelines to buildings and roads. "Global climates only slightly warmer than today are sufficient to thaw significant regions of permafrost,"...
Ice thaw could spell bad news for polar bears

Reuters: A thaw of sea ice floating on the Arctic Ocean last year sent extra plant food to exotic creatures on the deep sea floor in a shift that might leave polar bears hungry at the surface, scientists said on Thursday. The study, using robot submarines down to 4,400 metres (14,400 ft) deep, could be a glimpse of radical changes for life in the sunless depths of the Arctic Ocean after ice thinned and shrank to cover a record low area in September 2012. Scientists found large amounts of algae growing...
