The global warming alarmists have been telling porkies again, this time, Professor Richard Muller who portentously announced the demise of global warming scepticism in the Wall Street Journal recently.

Following this revelation, Prof Judith Curry from the Department of Earth and Atmospheric Sciences at the Georgia Institute of Technology accused Muller of hiding the fact that there has been no warming for the last 13 years.

Ironically, the Berkeley Earth Surface Temperature project, of which Muller is founder and chairman, has “A transparent approach based on data analysis”, emblazoned on its web page.

a leading member of Prof Muller’s team has accused him of trying to mislead the public by hiding the fact that BEST’s research shows global warming has stopped.

Prof Judith Curry, who chairs the Department of Earth and Atmospheric Sciences at America’s prestigious Georgia Institute of Technology, said that Prof Muller’s claim that he has proven global warming sceptics wrong was also a ‘huge mistake’, with no scientific basis.

Prof Curry is a distinguished climate researcher with more than 30 years experience and the second named co-author of the BEST project’s four research papers.
