In recent 50 years, glacier melting has intensified

On December 9, NASA released images of glacier changes around the world in recent 50 years. Time lapse photography shows that with global warming, glaciers are retreating faster, and the altitude of snow ice melt water is also rising. From 1985 to 2018, Greenland's glaciers retreated by an average of 5km, and the number of lakes on the ice sheet has increased by 27% in the past 20 years.
