Anthony Watts’s blog has not been updated for past couple of days. Anthony says he has something big to post in the next day or so.

There are rumours that Richard Muller of the University of California has prepared another article based on the temperature studies about which he wrote last year in the Wall Street Journal.

Basically, Muller said his work proved the world really was warming, so there was no excuse for global warming scepticism.

Sadly for Muller, he had missed the point. He, like most global warming alarmists, seemed to have no idea what the sceptics were actually saying. No one denies the world has warmed over the last one hundred and fifty years. No one denies that human activity can influence climate. The argument is about the extent of human influence, whether current climate change is unusual or dangerous, and if it is, what are the most economical and effective ways to deal with it.

Marc Morano summarised the scientific responses to Muller’s earlier article at Climate Depot.

This is a capture from Steven Goddard’s blog Real Science:

Nope, that 0.7 degree change has never happened before!

Update:

Anthony’s major post has nothing to do with any new work by Muller, but is a ‘pre-release’ of an important paper by Watts, Jones, McIntyre and Christy on NOAA station siting problems and post measurement adjustments.

A reanalysis of U.S. surface station temperatures has been performed using the recently WMO-approved Siting Classification System devised by METEO-France’s Michel Leroy. The new siting classification more accurately characterizes the quality of the location in terms of monitoring long-term spatially representative surface temperature trends. The new analysis demonstrates that reported 1979-2008 U.S. temperature trends are spuriously doubled, with 92% of that over-estimation resulting from erroneous NOAA adjustments of well-sited stations upward.

They conclude:

These factors, combined with station siting issues, have led to a spurious doubling of U.S. mean temperature trends in the 30 year data period covered by the study from 1979 – 2008.
