Society bloomed with gentler personalities and more feminine faces
Modern humans appear in the fossil record about 200,000 years ago, but it was only about 50,000 years ago that making art and advanced tools became widespread.
Research resolves discrepancy in Greenland temperatures during end of last ice age
A new study of three ice cores from Greenland documents the warming of the large ice sheet at the end of the last ice age – resolving a long-standing paradox over when that warming occurred.
Greenland Ice Sheet more vulnerable to climate change than previously thought
A new model developed by researchers at the University of Cambridge has shown that despite its apparent stability, the massive ice sheet covering most of Greenland is more sensitive to climate change than ...
Rising sea levels of 1.8 meters in worst-case scenario
The climate is getting warmer, the ice sheets are melting and sea levels are rising – but how much? The report of the UN's Intergovernmental Panel on Climate Change (IPCC) in 2013 was based on the best ...
