Greenland Lost 2 Gigatons of Ice in 1 Day
Greenland lost two gigatons of ice on Thursday in just one day.
Over 40 percent of Greenland experienced melting.
Such melting in one day is highly unusual for Greenland.
A similar spike occurred in June of 2012.
2019 could set records for the most ice lost.
The extreme ice melt is due to a ridge of high pressure that is bringing warm temperatures.
