Obligatory XKCD

That’s a very good graphic, and it’s no mere cartoon – it’s scientifically accurate. I’ve seen it before but forgot about it. The bottom part is essentially the famous hockey stick shape first put into the public consciousness by the paleoclimate reconstructions of Michael Mann et al. This is the sort of stuff that has climate deniers getting all their shorts in a knot, but unfortunately for them, it’s factually accurate.
