“Pielke Sr. on Revkin’s question“. In spite of abundant evidence to the contrary, Dr. Roger Pielke Sr. is more convinced than ever that NO! is his answer to a question posed in 2005 by journalist Andy Revkin: “Is most of the observed warming over the last 50 years likely to have been due to the increase in greenhouse gas concentrations?”

He now says that Dr. Spencer’s assertion that it’s all because of a reduction in cloud cover, in a somehow on-going 50 year pattern, explains it. Especially since he still thinks the “missing heat” statement by Kevin Trenberth last month was an admission that the heat “wasn’t there” rather than that it can’t be identified by current instrumentation.

Dr. Pielke backs his assertion with a collection of references to debunked denialist fellow-travelers and right-wing “conferences”. Confirmation bias in three, two, one, now.

[Note: In the comments Dr. Pielke thanks the WUWT readers for editorial corrections. My god, sloppy typing as well as sloppy thinking!]
