Satellites show Greenland’s melting ice is causing seas to rise

The video discusses the rapid melting of Greenland's ice sheet, which is increasing global flood risks. A study published on November 1st reveals that over the past decade, Greenland has lost over 3.5 trillion tons of ice, raising global sea levels by 1 cm. The ice sheet has the potential to raise sea levels by 6 meters if fully melted. Extreme melting events are becoming more frequent, with heat waves being a significant cause. In 2012, atmospheric changes led to the loss of 527 billion tons of ice. The research is pioneering in using satellite data to detect ice sheet runoff, showing significant annual variations.
