One of the world’s leading ice experts has predicted the final collapse of Arctic sea ice in summer months within four years. That’s earlier than the Earth’s predicted demise in December of 2012, but it could be a major cause of it.
In the September 17th edition of the Guardian, John Vidal quotes climatologist Peter Wadhams as calling it "a global disaster."

The Antarctic Ice Sheet may be a major source of the potent greenhouse gas methane. Old organic matter frozen beneath it may have been converted to methane by micro-organisms living there under oxygen-deprived conditions, and as the ice melts, the methane will be released.
Planetary scientist Slawek Tulaczyk says, "It is easy to forget that before 35 million years ago, when the current period of Antarctic glaciations started, this continent was teeming with life. Some of the organic material produced by this life became trapped in sediments, which then were cut off from the rest of the world when the ice sheet grew. Our modeling shows that over millions of years, microbes may have turned this old organic carbon into methane."
