BTW...

I was asked a question yesterday that I think is worth mentioning. Someone said, "So about this global warming thing...if it's real, why is it so cold today?" Yes, we are having unusually frigid weather in LA, and I know usually temperate Austin is covered in ice right now. The answer is that weather is different than climate and that you can't take the temperature of one day in one place as evidence for or against global warming. And remember, what's actually happening is global CLIMATE CHANGE. Because of the interconnectedness of what we call "biodiversity", we are just beginnning to understand all the ways that the climate is changing due to human activity, which includes unusual cooling in some places. For more on this issue, check out that trusty "How to talk to a skeptic" guide, specifically, this entry.
