A study led by the University of Barcelona and published in the journal Nature Communications shows that climate change has profoundly altered extreme episodes of melting in the Greenland ice sheet by making them more frequent, more extensive and more intense. Since 1990, the area affected by extreme melting episodes has increased at a rate of 2.8 million km² per decade. Additionally, the production of water from ice melt has increased more than sixfold, rising from 12.7 gigatons per decade to 82.4 gigatons per decade.
