David Zetland – Climate Change Alert: Life Is About To Get Much Worse

Climate change is hard for people to understand or take seriously because its FUTURE impacts will be so vast in scale and intensity. It would be easier for people to “believe in”face if its signs were more local and present (one reason I suggested rebranding it “local warming” years ago).

Sadly, it seems that we’re about the arrive in that moment of vast intensity a lot quicker than previously forecast.

Last week, James Hansen (one of the first scientists to bring CC to public attention) and many co-authors published an article (link in this summary) explaining how previous estimates of glacial melting in Antartica and Greenland need to be updated to consider positive feedback effects that are hastening the process. These effects are due to the slowing of ocean circulation that will simulataneously mean warmer seas near the Antarctic ice shelves (helping those glaciers slide into the water more quickly) as well as colder seas near Northern Europe (as the “conveyor” of warm water from the Caribbean shuts down).
