Over on RealClimate, they just posted my commentary on Monckton’s graphs of atmospheric CO2 and global mean temperature. The bottom line is that he made up false data and labeled it “IPCC Predictions” to discredit the IPCC. (“Look, their predictions are way off!!!”)
So far, I have personally checked into Monckton’s claims about being a member of the House of Lords, the IPCC’s CO2 and temperature “predictions”, solar variations as a climate driver, and long-term temperature history. In every case, I have found that Monckton has severely misrepresented the truth. If you have the slightest inclination to believe anything Lord Monckton says, start checking him out yourself!) A good place to start looking at what others have found is Lord Monckton’s Rap Sheet.
