Greenland Lost 18 Billion Tons Of Water During Freak 3-Day Heatwave

 Greenland  lost 18 billion tons of water in a devastating three-day heatwave as the Earth continued to reach extreme temperatures.   inews reports that one of the world's largest ice caps, containing enough water to raise sea levels by 7.42m (24.3ft) worldwide, is melting at a record rate.   Last weekend, temperatures in northern Greenland hit 15 degrees Celsius (60 degrees Fahrenheit), 10 degrees warmer than usual for this time of year, according to CNN.
