A new study published in Nature unveils a surprising discovery: a substantial amount of meltwater is temporarily stored within the Greenland Ice Sheet during summer months. For the first time, an international group of researchers was able to quantify meltwater with positioning data. The finding challenges current models of how ice sheets contribute to global sea level rise.

The Greenland Ice Sheet is currently the largest single contributor to global sea-level rise,

The study highlights the importance of international collaboration in addressing one of the planet’s most pressing environmental challenges.
