Climate scientists in Germany base the prediction on what they believe is an impending change in the Gulf Stream — the conveyor belt that transports warm surface water from the tropical Atlantic to the northern Atlantic and returns cold water southwards at depth.
The Gulf Stream will temporarily weaken over the next decade, in line with what has happened regularly in the past, the researchers say.
This will lead to slightly cooler temperatures in the North Atlantic and in North America and Europe, and also help the temperatures in the tropical Pacific to remain stable, they suggest.
Last year, scientists in the UN’s Intergovernmental Panel on Climate Change (IPCC) said that by 2100, global average surface temperatures could rise by between 1.1 C and 6.4 C (1.98 and 11.52 F) compared to 1980-99 levels.
In the next 20 years alone, the global climate would warm by around 0.2 degrees Celsius (0.36 degrees Fahrenheit) per decade, the IPCC said.
