“Mysterious Craters Are Just the Beginning of Arctic Surprises…” [#geekgirl]

The Artic = sad

[From this Scientific American article] “It’s not just craters purportedly dug by aliens in Russia, it’s also megaslumps, ice that burns and drunken trees. The ongoing meltdown of the permanently frozen ground that covers nearly a quarter of land in the Northern Hemisphere has caused a host of surprising arctic phenomena.

Temperatures across the Arctic are warming roughly twice as fast as the rest of the globe, largely due to the reduction in the amount of sunlight reflecting off of white, snow-covered ground. “At some point, we might get into a state of permafrost that is not comparable to what we know for 100 years or so, some new processes that never happened before,” says geologist Guido Grosse of the Alfred Wegener Institute for Polar and Marine Research in Germany.”
