Personally, I think methane hydrates (http://www.independent.co.uk/environment/climate-change/exclusive-the-methane-time-bomb-938932.html) will get us before the ice caps do, but that's neither here nor there.

I've been eager for clones and braintaping since I was a small girl, but so far, the best I can do is be an evangelist for science by learning from others, sharing knowledge, teaching people, and encouraging others to do the same.
