The recent heat wave that broke temperature records across Europe broke different records when it arrived in Greenland. On August 1, the Greenland Ice Sheet experienced its biggest single-day of ice loss in recorded history. About 12.5 billion tons of ice melted and poured into the Atlantic Ocean, satellite data showed. One day earlier, over 10 billion tons of ice melted. Every 1 billion tons of ice lost creates enough water to fill 400,000 Olympic swimming pools, the Danish Meteorological Institute noted late last week. The center offered the comparison to help people try to understand just how much ice melted. One Danish scientist offered a different comparison. Climate expert Martin Stendl said the total ice that melted in Greenland on July 31 and August 1 could cover all of Germany with seven centimeters of water.
