Pretty scary stuff. Here is a key excerpt from the Chris Mooney piece:
Impacts of Arctic warming are usually considered in isolation, and that’s a mistake, he says [Rafe Pomerance]. “It’s unraveling, every piece of it is unraveling, they’re all in lockstep together,” Pomerance says. “What tends to happen is, everybody nationally reports on the latest piece of news, which is about one system. You hear about the sea ice absent the temperature trend. So you really have to think of it as a whole.”
