An international team of scientists, led by Professor Jonathan Bamber from the School of Geographical Sciences, reconstructed Greenland's freshwater losses from 1958 to 2010 in a paper published in Geophysical Research Letters.
Professor Bamber said: "Greenland has been losing increasing amounts of mass. What had been unclear was how much of that was due to losing water to the ocean, as opposed to factors like reduced snowfall."
Such an increase in the volume of fresh water flowing into the Atlantic could interfere with the Atlantic Meridional Overturning Circulation (AMOC), the current that carries warm tropical water to northern Europe. It could also reduce the ocean's ability to store carbon.
The research was covered by New Scientist: 'Run-off from Greenland may weaken carbon sink'.
