Nothing scandalous about that. He thinks the global average temp in 20 years won't be much different than now.


Lets look at this in a little detail just to expose you guys.

From the IPCC, 2007 the best estimate for surface temp increases (global average) at the end of 2100 is 1.8-4.0 deg C above the 1980-1990 baseline. Lindzen's bet was over the range of (approx) 2000-2020. Scaling off the graph shown in the link, the temp change in the first few decades of this century is 2 deg C/100 years or 0.4 deg C in 20 years.

So what exactly is Lindzen up to in this bet? He will only lose the bet if the global warming is > then the best estimates of the existing models the IPCC reports. And he will only do this if he gets 2:1 odds in his favor.

Anyone who thinks Lindzen is a AGW denier, other than for collecting speaking fees, is a moron.
