Could we be in for 30 years of global COOLING? January 12, 2010

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.
