The Greenland ice sheet is losing its ability to soak up glacier meltwater as result of climate change, according to years-long research.
The Greenland ice sheet is losing its ability to soak up glacier meltwater as result of climate change, according to years-long research.
York University Professor William Colgan detailed three extensive expeditions to Greenland in 2012, 2013 and 2015 in the journal Nature Climate Change.
Colgan’s team spent weeks drilling into firn, a porous layer of ice near the surface that typically acts like a sponge to soak up meltwater.
What the team discovered was distressing: a solid sheet of ice had formed directly on top of the spongy firn after a prior years' melt.
