I have not doubt that, somewhere, in some progressive children's magazine, the follow public service announcement appears next to an ad for Pokemon cards (or whatever's passing for toys nowadays.)
While I'm sure that there are studies that show interesting data about global warming, I highly doubt any of the evidence is conclusive.
Also, Shane cheated. I drew my polar bear first and he changed the date on his post to make it look like I was copying him. Boo, Shane!
