This article at WUWT is a “must read”. It is a very clear and very accurate presentation of what is wrong with the Global Warming Church and Paranoia (my term). Only real ‘error’ I see in it is that he believes the temperature record of 0.8 C of “warming” when the reality is that at least 1/2 C of that is questionable “adjustments” and homogenizing, and the rest is likely bad siting of thermometers over tarmac at airports.
Still, it is well written and a good read. If you have not read it, do.
