Scientists analysing ancient ice samples say that the Greenland ice sheet withstood temperatures much higher than today's for many thousands of years during a period of global warming more than 120,000 years ago, losing just a quarter of its mass. It had been widely suggested - by the UN Intergovernmental Panel on Climate Change for instance - that any such warming would melt the entire sheet, leading to massive sea-level rises.
The new research was carried out by analysing a 2.5km long ice core drilled from the Greenland ice last year by a major scientific expedition involving top boffins from around the world. The core data showed that 115 to 130 thousand years ago, temperatures above the Greenland ice were much higher than they are today: 8±4°C, in fact…To Read More….
