Are we ready for global cooling????
Here's yet another theory....
Britain's big freeze is the start of a worldwide trend towards colder weather that seriously challenges global warming theories, eminent scientists claimed yesterday.
The world has entered a 'cold mode' which is likely to bring a global dip in temperatures which will last for 20 to 30 years, they say.
Summers and winters will all be cooler than in recent years, and the changes will mean that global warming will be 'paused' or even reversed, it was claimed.
The predictions are based on an analysis of natural cycles in water temperatures in the Pacific and Atlantic oceans.
They are the work of respected climate scientists and not those routinely dismissed by environmentalists as 'global warming deniers'.
Some experts believe these cycles - and not human pollution - can explain all the major changes in world temperatures in the 20th century.
If true, the research challenges the science behind climate change theories, and calls into question the political measures to halt global warming.
According to some scientists, the warming of the Earth since 1900 is due to natural oceanic cycles, and not man-made greenhouse gases.
It occurred because the world was in a 'warm mode', and would have happened regardless of mankind's rising carbon dioxide production.
And now oceanic cycles have switched to a 'cold mode', where data shows that the amount of Arctic summer sea ice has increased by more than a quarter since 2007.
The research has been carried out by eminent climate scientists, including Professor Mojib Latif. He is a leading member of the UN's Intergovernmental Panel on Climate Change.
He and his colleagues predicted the cooling trend in a 2008 paper, and warned of it again at an IPCC conference in Geneva in September.
Working at the prestigious Leibniz Institute in Kiel University in Germany, he has developed methods for measuring ocean temperatures 3,000ft under the surface, where the cooling and warming cycles start.
For Europe, the crucial factor is the temperature in the middle of the North Atlantic Ocean. He said such ocean cycles - known as multi-decadal oscillations or MDOs - could account for up to half of the rise in global warming in recent years.
Professor Latif said: '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 - as much as 50 per cent.
'They have now gone into reverse, so winters like this one will become much more likely. All this may well last two decades or longer.
