New paper finds global warming over past century was only about half of IPCC claims
'A recent paper presented at European Geosciences Union meeting finds global warming over past century was only about one-half [0.42°C] of that claimed by IPCC [0.7-0.8°C]. The paper finds that in 2/3 (67%) of 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%).'"
