The bitter winter afflicting much of the Northern Hemisphere is only the start of a global trend towards cooler weather that is likely to last for 20 or 30 years, say some of the world’s most eminent climate scientists.
Their predictions – based on an analysis of natural cycles in water temperatures in the Pacific and Atlantic oceans – challenge some of the global warming orthodoxy’s most deeply cherished beliefs, such as the claim that the North Pole will be free of ice in
summer by 2013.
According to the US National Snow and Ice Data Centre in Colorado, Arctic summer sea ice has increased by 409,000 square miles, or 26 per cent, since 2007 – and even the most committed global warming activists do not dispute this.
They say that their research shows that much of the warming was caused by oceanic cycles when they were in a ‘warm mode’ as opposed to the present ‘cold mode’.
This challenge to the widespread view that the planet is on the brink of an irreversible catastrophe is all the greater because the scientists could never be described as global warming ‘deniers’ or sceptics.
However, both main British political parties continue to insist that the world is facing imminent disaster without drastic cuts in CO2.
Last week, as Britain froze, Climate Change Secretary Ed Miliband maintained in a parliamentary answer that the science of global warming was ‘settled’.
Among the most prominent of the scientists is Professor Mojib Latif, a leading member of the UN’s Intergovernmental Panel on Climate Change (IPCC), which has been pushing the issue of man-made global warming on to the international political agenda since it was formed 22 years ago.
Prof Latif, who leads a research team at the renowned Leibniz Institute at Germany’s Kiel University, has developed new methods for measuring ocean temperatures 3,000ft beneath the surface, where the cooling and warming cycles start.
He and his colleagues predicted the new cooling trend in a paper published in 2008 and warned of it again at an IPCC conference in Geneva last September.
Last night he told The Mail on Sunday: ‘A significant share of the warming we saw from 1980 to 2000 and at earlier periods in the 20th Century was due to these cycles – perhaps as much as 50 per cent.
'They have now gone into reverse, so winters like this one will become much more likely. Summers will also probably be cooler, and all this may well last two decades or longer.

"Global satellite data is analyzed for temperature trends for the period January 1979 through June 2009. Beginning and ending segments show a cooling trend, while the middle segment evinces a warming trend. The past 12 to 13 years show
cooling using both satellite data sets, with lower confidence limits that do not
exclude a negative trend until 16 years. It is shown that several published studies
have predicted cooling in this time frame. One of these models is extrapolated
from its 2000 calibration end date and shows a good match to the satellite data,
with a projection of continued cooling for several more decades."
