I have an interesting global warming eye test up at Climate-Skeptic. The two graphs below are both scaled exactly the same, and are each 51-year periods from the global temperature record of the last 150 years. The only difference is that one period of warming is described by scientists as "natural" (1895 to 1946) and the other is described as "man-made" (1957 to present).
Which is which? Which is man, and which is mother nature?
Kind of makes the claim that "current warming is unprecedented" ring kind of hollow, huh?
