notscientific writes: The face of the Arctic is changing as plant growth flourishes further north than before. NASA had already estimated that vegetation at northern latitudes resemble those found at much lower latitudes only 30 years ago. Now, in a paper published by Nature Climate Change, scientists detail how this effect is due to manmade climate change. Increasingly aggressive plant growth at the detriment of Arctic permafrost is disconcerning as the amount of carbon trapped in permafrost---but which will be released during melting---will eventually be too much for the plants to keep up with.
