Another analysis of historical temperatures has come out. The Look has summarized the article and presented the graph. The graph is a bit hard to interpret because it spikes so severely between 1900 and 2002. We're not talking hockey stick, we're talking rocket.
The easiest thing to do is follow the blue line for the 2001-2005 mean. The earth was super hot 400,000 years ago, and we're still about 1 degree C short of that. That was the hottest earth in 1.35 million years - as far back as we can go. If we don't do some radical CO2 reduction however, we'll blow by that record (pass it by a whopping 2 degrees C) and move out of the range of human evolutionary history.
