"An iceberg twice the size of New York City is about to break off of Antarctica's Brunt Ice Shelf, according to NASA."

"As warming brings earlier spring rains in the Arctic, more permafrost thaws, releasing more methane in a difficult-to-stop feedback loop, research shows."

"Increasing spring rains in the Arctic could double the increase in methane emissions from the region by hastening the rate of thawing in permafrost, new research suggests.

"Human emissions of greenhouse gases are driving rapid warming all over the globe — particularly in the Arctic, where temperatures are rising at about twice the global rate. But there's another form of carbon in the atmosphere that may also be playing a role."

"The ice in Antarctica is melting six times faster than it did just 40 years ago, a new study reports.

This dramatic acceleration of the ice loss is a clear indication of human-caused climate change, the study authors said.

Lead author Eric Rignot, an ice scientist at the University of California–Irvine, said the melting ice has caused global sea levels to rise more than half an inch since 1979.  

While that may not sound like much, the amount is certainly alarming to climate scientists, as it's a preview of things to come:"

"Rapid warming and vanishing sea ice in the Arctic has enabled new species, from humpback whales to white-tailed deer, to spread northward. Scientists are increasingly concerned that some of these new arrivals may be bringing dangerous pathogens that could disrupt the region’s fragile ecosystems."

"Arctic sea ice behaves a bit like a human waistline, packing on weight in the winter and slimming down in the heat of summer. But while many of us struggle to lose weight, the Arctic has been struggling to gain it."

"In just eight days in mid-February, nearly a third of the sea ice covering the Bering Sea off Alaska's west coast disappeared. That kind of ice loss and the changing climate as the planet warms is affecting the lives of the people who live along the coast."

As climate change melts Arctic permafrost, it will release toxic mercury, scientists say.
