Global warming over past century was half of IPCC claims

Posted by Geoff Brown on July 18, 2012

HockeySchtick reports on a new paper presented at the European Geosciences Union meeting. The paper finds:

......global warming over the past century was only about one-half [0.42°C] of that claimed by the IPCC [0.7-0.8°C]. The paper finds that in 2/3 (67%) of the weather stations examined, questionable adjustments were made to raw data that resulted in "increased positive trends, decreased negative trends, or changed negative trends to positive," whereas "the expected proportions would be 1/2 (50%)."

It's not even peer reviewed.

Also this:

"of 67% of the weather stations examined, questionable adjustments were made to raw data that resulted in: "Increased positive trends, decreased negative trends, or changed negative trends to positive,” whereas “the expected proportions would be 1/2 (50%)."

is plainly false.

Poor old Al Einstein didn't get his theory of relativity peer reviewed. Shame, Al, Shame.
