Following my statement at the Doha climate conference last December that there had been no global warming for 16 years, Dr. Rajendra Pachauri, the railroad engineer who for some reason chairs the IPCC’s climate “science” panel, has been compelled to admit there has been no global warming for 17 years.
The Hadley Centre/CRU records show no warming for 18 years (v.3) or 19 years (v.4), and the RSS satellite dataset shows no warming for 23 years (h/t to Werner Brozek for determining these values).
Engineer Pachauri said warming would have to endure for “30 to 40 years at least” to break the long-term global warming trend. However, the world’s leading climate modelers wrote in the NOAA’s State of the Climate report in 2008 that 15 years or more without warming would indicate a discrepancy between the models and measured reality.
The Australian reports: Dr Pachauri … said that open discussion about controversial science and politically incorrect views was an essential part of tackling climate change.
“In a wide-ranging interview on topics that included this year’s record northern summer Arctic ice growth, the US shale-gas revolution, the collapse of renewable energy subsidies across Europe and the faltering European carbon market, Dr Pachauri said no issues should be off-limits for public discussion.
“In Melbourne for a 24-hour visit to deliver a lecture for Deakin University, Dr Pachauri said that people had the right to question the science, whatever their motivations.
“‘People have to question these things and science only thrives on the basis of questioning,’ Dr Pachauri said.
“He said there was ‘no doubt about it’ that it was good for controversial issues to be ‘thrashed out in the public arena’.
“Dr Pachauri’s views contrast with arguments in Australia that views outside the orthodox position of approved climate scientists should be left unreported.
“Unlike in Britain, there has been little publicity in Australia given to recent acknowledgment by peak climate-science bodies in Britain and the US of what has been a 17-year pause in global warming. Britain’s Met Office has revised down its forecast for a global temperature rise, predicting no further increase to 2017, which would extend the pause to 21 years.”

THE UN's climate change chief, Rajendra Pachauri, has acknowledged a 17-year pause in global temperature rises, confirmed recently by Britain's Met Office, but said it would need to last "30 to 40 years at least" to break the long-term global warming trend.
Dr Pachauri, the chairman of the UN's Intergovernmental Panel on Climate Change, said that open discussion about controversial science and politically incorrect views was an essential part of tackling climate change.)
Given that the IPCC spends a great deal more thought on getting the propaganda spin right than on doing climate science, one should be healthily suspicious of what Engineer Pachauri is up to.
Inferentially, the bureaucrats have decided they can no longer pretend I was wrong to say there has been no global warming for 16 years. This one cannot be squeezed back into the bottle. So they have decided to focus on n years without warming so that, as soon as an uptick in temperature brings the period without warming to an end, they can neatly overlook the fact that what really matters is the growing, and now acutely embarrassing, discrepancy between predicted and observed long-term warming rates.
At some point – probably quite soon – an el Niño will come along, and global temperature will rise again. Therefore, it would be prudent for us to concentrate not only on the absence of warming for n years, but also on the growing discrepancy between the longer-run warming rate predicted by the IPCC and the rate that has actually occurred over the past 60 years or so.
Since 1950 the world has warmed at a rate equivalent to little more than 1 Celsius degree per century. Yet the IPCC’s central projection is for almost three times that rate over the present century. We should keep the focus on this fundamental and enduring discrepancy, which will outlast a temporary interruption of the long period without global warming that the mainstream media once went to such lengths to conceal.
What this means is that the UN’s attempt to ban me from future annual climate gabfests for telling delegates at Doha that there had been no global warming for 16 years will fail, because soon there will be no more annual climate gabfests to ban me from.
