That’s because Greenland’s massive ice sheet locks up more than six
percent of the world’s fresh water supply, and it is melting much
faster than expected. If Greenland were to melt fully, it would cause
sea levels around the globe to rise by nearly 20 feet. Even
measurements of four to five feet of sea level rise could mean that
places like New York, Amsterdam, Venice and Bangladesh will experience flooding
in low
lying areas. More
than 70 percent of the world's population lives on flat coastal plains.
The Arctic Sunrise arrived in Greenland at the end of June, with
scientists from around the world onboard. The ship and its crew have
been documenting and measuring the impacts of global warming.

The alarming retreat of the Kangerdlugssuaq Glacier suggests that the entire
Greenland ice sheet may be melting far more rapidly than previously
believed. All
current scientific forecasts for global warming had assumed slower
rates of melting. This new evidence suggests that the threat of global
warming is much greater and more
urgent than previously believed.
In addition to the increased speed of the glacier,
scientists from the
University of Maine found that the Kangerdlussuaq glacier has receded
more than three miles since 2001. Measurements from glaciers across
Greenland are providing startling new evidence of thinning, causing the
glaciers to speed up and decrease in overall mass, intensifying the
flow of ice into the ocean.
“The alarm is now deafening. We can’t stand back and watch our future
go under, literally,” said Melanie Duchin, Greenpeace campaigner
onboard the Arctic Sunrise. “We must stop generating global warming
pollution."
