Scientists reported that the coldest and highest parts of the Greenland ice sheet, nearly two miles above sea level in many locations, are warming rapidly and showing unprecedented changes in at least a millennium.
The work also found that compared with the 20th century as a whole, this part of Greenland, the enormous north-central region, is now 1.5 degrees Celsius (2.7 degrees Fahrenheit) warmer and that the rate of melting and water loss from the ice sheet — which raises sea levels — has increased in tandem with these changes.
