Facts Cannot Slow Down the Runaway Climate Confusion Train

Saturday night I sent the Tweet you see below because, once again, there are people who are criticizing Dr. Michael Mann’s “hockey stick” research that shows today’s climate is warmer than at any time in the past 2000 years. The latest attempt to discredit Mann’s work comes from Dr. Judith Curry’s post titled Fraudulent(?) hockey stick where she writes “accusations of data cherry picking and flawed statistical analyses and interpretations seem to be justified. ” Dr. Curry and others should know that the hockey stick curve shows up in other research even when using different types of data and different types of data analyses. (I blogged about this in 2010 with Shooting the Messenger with Blanks.)

Enter Paul Clark (@cbfool). His three main points were:

1. Hockey sticks are based on tree rings and tree rings are unreliable
2. Ice core data from Greenland shows the past was much warmer than today
3. Greenland in the 1200s was more conducive to agriculture than today so it must have been warmer than today
