In the coldest years of the last ice age, the ice cap reached the British Isles and Poland. New research has revealed a green patch much closer to the North Pole. Part of a peninsula in Svalbard was free from ice.
The natural climate system has mechanisms that can abruptly trigger change. New research suggests that spontaneous cooling may have caused Arctic glaciers to grow long before the Little Ice Age, without external forcing.
A newly published study in Nature Communications shows an important new understanding of the climate system that will allow us to better understand past climate variability. The results were uncovered by expeditions between the North Pole and Antarctica.
