Anthony Watts seems proud of himself, having posted his presentation at the recent “anti-climate” conference of the “Heartland Institute.” He talks mainly about the fact that temperature data are often adjusted before including them in forming a global (or regional) average.
He says that the adjustments are the reason for the apparent rise in temperature that has people so worried. He often implies that un-adjusted data are “truth” and that any adjustment is a violation of its sanctity, together with the implication that those who do so are perpetrating a fraud. It’s standard climate denier talk.
Fortunately, people aren’t buying their brand of snake-oil any more. But the subject at hand — making adjustments to temperature data before including it in global/regional averages — deserves interest, mainly because it’s actually interesting.
