Forget 'climate convert' Muller: Here's the real warming blockbuster

Apply official WMO methods, warming shrinks massively: The Register
"If new techniques endorsed by the World Meteorological Organisation are applied to official figures, over half of the global warming reported by US land-based thermometers between 1979 and 2008 simply disappears, researchers have found. ....Yet it has been left to a group largely outside the climate establishment to first do the field work and then the maths, and apply the new metric to the data. The official agencies and climate academics have been able (some would say, required) to use the latest WMO-endorsed categorisation method for 18 months, but have failed to do so. Enter Watts et al The new paper is co-authored by TV weatherman and blogger Anthony Watts, the Climate Audit blog's Evan Jones and Stephen McIntyre, and Dr John Christy from the Department of Atmospheric Science at the University of Alabama, Huntsville. Only Christy, who maintains the US satellite temperature monitoring network, can be considered part of the scientific climatology establishment. ......Strikingly, NOAA's reliance on low-quality thermometers is made clear when airport stations are examined. The WMO's new classification scheme means 601 of 727 airports examined in the sample are non-compliant and low quality: ......The Watts work has significant implications. For example, work by climate activist and scientist James Hansen, who has overseen the NASA global temperature record's major increases, and Richard Muller's recent BEST programme - much in the news lately owing to his putative status as a "convert" to climate alarmism - use cruder station classification systems. Their statistical methods may be unimpeachable, but it now appears that they are using unreliable data sets."
