Tim Radford – Ocean current sends out chilling warning

New research forecasts much colder weather in northern Europe if rising CO2 emissions continue to impact on the Atlantic ocean current. LONDON, 8 January, 2017 – Here is the long-term weather forecast for the North Atlantic, in a world in which carbon dioxide concentrations in the atmosphere double: a powerful ocean current called the Atlantic Meridional Overturning Circulation (AMOC) will continue …

Melting Greenland ice sheet may affect global ocean circulation, future climate

Scientists from the University of South Florida, along with colleagues in Canada and the Netherlands, have determined that the influx of fresh water from the Greenland ice sheet is “freshening” the North Atlantic Ocean and could disrupt the Atlantic Meridional Overturning Circulation (AMOC), an important component of global ocean circulation that could have a global effect. Researchers say it could …

Retreating sea ice linked to changes in ocean circulation, could affect European climate

Retreating sea ice in the Iceland and Greenland Seas may be changing the circulation of warm and cold water in the Atlantic Ocean, and could ultimately impact the climate in Europe, says a new study by an atmospheric physicist from the University of Toronto Mississauga (UTM) and his colleagues in Great Britain, Norway and the United States. “A warm western …

What’s Going On In The North Atlantic?

The North Atlantic between Newfoundland and Ireland is practically the only region of the world that has defied global warming and even cooled. Last winter there even was the coldest on record – while globally it was the hottest on record. Our recent study (Rahmstorf et al. 2015) attributes this to a weakening of the Gulf Stream System, which is …
