How Arctic warming's effects are spilling elsewhere

Jet stream changes. Icebergs moving further south, too. That's all part of the fallout of global-warming induced changes in the Arctic. Among other things, as more big icebergs break off Greenland, they're going to get pushed deeper into the Atlantic by new wind patterns.

And, yet, the U.S. fiddles while Baffin Island roasts.

Canadian Thomas Homer-Dixon notes:
(W)e’ll almost certainly need some kind of devastating climate shock to get effective climate policy. That’s the key lesson of the recent financial crisis: when powerful special interests have convinced much of the public that what they’re doing isn’t dangerous, only a disaster that discredits those interests will provide an opportunity.

The shock?

Maybe, if a couple of North Atlantic offshore oil platforms get damaged by a big-enough Greenland berg, Big Oil will tell the GOP to wise up, but not likely
