Long-lost Greenland ice core suggests potential for disastrous sea level rise
If Greenland’s ice sheet saw rapid melting during a period of moderate warming, it “may be more sensitive to human-caused climate change than previously understood – and will be vulnerable to irreversible, rapid melting in coming centuries,” the study authors said in a statement.
This would have significant impacts on sea level rise. If Greenland’s ice sheet were to melt completely, sea levels would rise by about 7 meters (23 feet) causing devastation to the billions who live along the world’s coasts.
