"There certainly has not been a hiatus in global warming — global warming hasn't stopped, even though you still hear those contrarian talking points," he says.
Professor Mann, the director of the university's Earth System Science Centre, is famous for his 'hockey stick' graph that reconstructed 1,000 years of global temperatures showing a dramatic spike towards the end of the 20th century.
The 'pause', also known as the 'slow down' or the 'hiatus', refers to the average rate of warming across the whole planet's surface in the last 15 years or so. The latest major report (pdf) from the United Nations Intergovernmental Panel on Climate Change said the rate of warming between 1998 and 2012 had been about 0.05°C per decade.
This rate, the report said, was "smaller than the rate calculated since 1951" which was 0.12°C per decade.
"The occurrence of the hiatus in global mean surface temperature trend during the past 15 years raises the two related questions of what has caused it and whether climate models are able to reproduce it," the report said (pdf).
This was proof enough for some commentators that computer models of the climate were wrong and that the risks of global warming may have been overblown.
Businessman and former ABC chairman Maurice Newman, the Prime Minister's top business advisor, has written that "temperatures have gone nowhere for 18 years".
Dr Scott Power, senior principal research scientist at the Bureau of Meteorology, was an author of the IPCC report.
"If you look at just these 15-year periods of globally averaged surface air temperature, then they fluctuate quite a bit," he says.
"We expect these fluctuations. What we know is happening is that the planet is warming in response to human increase in greenhouse gases very largely but there are fluctuations because of natural processes."

You know I agree totally with that headline...it certainly isn't good news.
I mean if the "pause" continues, how will they convince people that dumping a hundred billion dollars (indexed to rise) yearly into some "fund" is going to "save the world"...? How will the convince the public that pouring billions of their dollars into paying for natural disasters in another country as some sort of penalty for "causing" global warming with our modern lifestyles?
