UAH Global Temperature Anomaly Down by .12C in February

UAH Global Temperature Update for February 2014: +0.17 deg. C (Note, my original headline number was unintentionally misleading, using a percentage to illustrate the drop rather that the absolute number. While the calculation was correct, it gave an impression of overall magnitude across the entire scale rather than the month to month change. It has…

NCDC cites “controversy” with the UAH temperature record, and the search for a “true climate signal”

This article in the January/February edition of WIRES Climate Change doesn’t surprise me at all. With the uncertainty of the surface temperature record in question, the Met Office’s Peter Thorne and NCDC’s Tom Peterson, who once wrote a ghost authored attack against the surfacestations project, take aim to elicit controversy (their word) over Christy and…
