I'd like to welcome Kate of ClimateSight to the climogosphere.
In addition to a few xkcd-ish cartoons, Kate has remarkably sophisticated observations about the climate debate. I feel like qualifying that with "for a high school student" but that would be unfair. If most of the population had a tiny fraction of the insight Kate brings to this question we'd be vastly better off.
Kate describes herself as an "aspiring climatologist". Watch out, world!
PS - Yes, she's Canadian, of course.
