New Arctic Ozone Hole Could Mean Reductions in Europe's Winter Wheat Crop

You may have heard that there's a massive new ozone hole in the Arctic--the first time there's been one there. Well, ThinkProgress has a good rundown (tag-teaming it seems with Jeff Masters from Weather Underground) on why its really potentially bad for food security, thanks to impacts on crop yields.From the intro (emphasis in the original):

An unprecedented ozone hole opened in the Arctic during 2011, researchers reported this week in the journal Nature....  We know that an 11% increase in UV-B light can cause a 24% decrease in winter wheat yield (Zheng et al., 2003), so this year's Arctic ozone hole may have caused noticeable reductions in Europe's winter wheat crop....

It is highly probable that we will see future nasty climate change surprises far more serious than the Arctic ozone hole if we continue on our present business-as-usual approach of emitting huge quantities of greenhouse gases. Humans would be wise to act forcefully to cut emissions of greenhouse gases, as the cost of inaction is highly likely to be far greater than the cost of action.
