In an era of global warming, why is arctic cooling?

Short answer: it's the hole in the ozone that's causing the arctic to cool while the rest of the globe is warming, according to a report at CNN (which by the way, sadly, dismantled its internal science and technology desk last month).

The cooling, "due to circulation changes which are partly caused by ozone depletion," should be ending soon as global efforts lead to an expected recovery in ozone levels. Then what? "Antarctic warming trends will emerge more clearly," one expert told CNN.

About Me

I started pound360 to channel my obsession with vitamins, running and the five senses. Eventually, I got bored focusing on all that stuff, so I came back from a one month hiatus in May of 2007 (one year after launching Pound360) and broadened my mumblings here to include all science.
