What is the price of our delay?
Greenland’s ice is melting faster than scientists predicted a few years ago. Incredibly, a sizable bloc of people work to stop action against climate change, claiming that it’s not occurring, or that it’s natural and shouldn’t be stopped, or that we can’t afford to save the planet this time.
Polar oceanographer Mark Brandon calls our attention to a good lay article in Discover Magazine’s .blog Imageo, by Tom Yulsman:
As brutal heat grips parts of Europe, Asia, North America and South America, another place is also experiencing a spike in temperatures — one that you may not have heard about.
It’s happening in Greenland, and high temperatures there over the past two weeks have caused a sudden jump in melting at the surface of the vast ice sheet (seen in that great expanse of white in the satellite image above).
Science critics argue the warming is slowing down, and will soon stop. Wish they were right. 18 years of their being wrong makes me skeptical.

In the meantime, as Galileo might have said, “Eppure, lei si scalda!” — still, she warms.
