Wait, The Ozone Hole is a Good Thing?

That hole in the ozone layer over Antarctica may be keeping the globe cool according to a couple of recent reports. This according to a recent report at Scientific American.

For decades, chemicals led by chlorofluorocarbons (CFCs) were gouging a hole in the ozone layer above the South Pole. Ozone is important since it blocks some ultraviolet radiation.

Then in 1996 an international ban on CFCs has helped shrink the hole. But if it's sealed, computer models show wind patterns that keep Antarctica cool (the "westerlies") could be altered, and the icy continent could melt more rapidly than it already is.

Scientists also theorize the ozone layer could trap greenhouse gasses and accelerate warming at the South Pole.

Does this mean the hole in the ozone is a good thing? Pound360 thinks higher UV radiation levels are a pretty steep price to pay for a cooler planet.

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.
