Scientists discover why is the North Pole frozen
Barcelona, Spain - Ice has been building up in the Arctic for 2.7 million years. Until now, no-one has been able to prove what mechanism brought about this accumulation of ice. However, a team of international scientists led by Antoni Rosell, a researcher for the Universitat AutÚnoma de Barcelona, and Gerald H. Haug of the Potsdam Institute for Climate Impact Research (Germany) has discovered the mechanism that set off the accumulation of ice.
A sudden fall in average world temperatures 2.7 million years ago caused the Arctic Ocean to freeze and Europe and North America to become covered in ice.
