I, too, am skeptical that the sky is blue, space is black, and that the planets orbit the sun. I mean, I haven't directly observed space or the planets, so the scientific approach is to be skeptical. I also hold out some tiny hope that electrons aren't real and microprocessors are powered by multi-dimensional hamsters.

It is denialism--really, it's willful, militant ignorance--at this point to go against the consensus on climate change. It's just being obtuse.

All I can say is, buckle the F up, because the effects of climate change are compounding year by year and decade by decade. I am so confident in this, after reading tons on the subject, having been all over the world and seen it, that I'll just leave it there.
