Luck O'The Leprechaun!

St. Patrick's Day approaches, and you know what that means! No, not vomiting drunkards clogging the subways with menacing, slurred epithets, silly!  It's time for the United States Geological Survey's March Science Picks!!!!!!  Huzzah!

You're probably getting tired of my USGS posts, but I don't care! I mean, who else can couch scientific research on global warming in terms of ravaging carpets of clover decimating non-indigenous biomes so hilariously!
