Greenland is said to have recently lost two billion tons of ice from its ice sheet after an unprecedented warm spell hit the region. The sudden spike in melting has been called "unusual" by researchers. Experts explained that the thaw resulted from hot and humid air from the Atlantic Ocean flowing into Greenland. This amount of ice melt could have significant ramifications around the globe, especially for sea level rise.
