More fresh water isn't always a good thing. The volume of fresh water gushing into the Atlantic from Greenland has increased in the past few decades. The water will interfere with Atlantic currents and may even reduce the ocean's ability to store carbon.
"Greenland has been losing increasing amounts of mass," says Jonathan Bamber of the University of Bristol in the UK. What had been unclear was how much of that was due to losing water to the ocean, as opposed to factors like reduced snowfall.
