Climate System "Getting Unhinged" as Massive Heat Wave Causes Record Melting of Greenland Ice Sheet

The massive heat dome that shattered all-time temperature records across much of Europe last week has settled in over Greenland, driving temperatures across the vast region to as much as 30 degrees Fahrenheit above normal. In July, Greenland's ice sheet lost 197 billion tons of ice, the equivalent of around 80 million Olympic swimming pools. This comes as the World Meteorological Organization said Thursday that July was the warmest month in recorded human history. It followed the hottest June on record, as atmospheric carbon dioxide levels climbed to a record high of 415 parts per million earlier this year. We speak with Jason Box, professor and ice climatologist at the Geological Survey of Denmark and Greenland.
