Is the Arctic Fridge becoming a Heater?
I’ve just come back from the studio where I was recording an interview with Dr. Martin Sommerkorn, Senior Climate Advisor with WWF’s Arctic Programme.
He was talking about the drastic decline of Sea Ice in the Arctic. It seems set to reach its lowest ever, and he tells us the scientists are desperately trying to revise their models to reflect this. “Reflect” is an appropriate word, because the most worrying thing is that white snow and ice reflect the sun’s heat back up off the earth, keeping the planet cooler. Darker water, on the other hand, absorbs it, heating up the planet further.
He says the Arctic could soon stop acting as a fridge that cools the planet and become a heater.
He explains it very well, so here’s the interview for a listen.
There will be a longer version available later in the week. I’m keeping it short here because it not everybody has broadband and a fast computer.
