Greenland Icesheet Could Melt Faster Than Scientists Thought A
new study released on Wednesday showed the Greenland icesheet
responded to global warming over the past 10,000 years more
quickly than thought, AFP reported. The report suggests that as
a result, a medium-sized temperature increase this century could
cause the continent-sized ice block to start melting at an
alarming rate. The study warns that it is entirely possible that
a future temperature increase of a few degrees Celsius in
Greenland will result in a icesheet mass loss and contribution
to sea level rise larger than previously projected. There is
enough ice in Greenland to raise sea levels by about 23 feet,
should it melt. But experts say that even a far more modest
increase would put major coastal cities under water and force
hundreds of millions of people to flee. Many experts were
confident that the planet’s two icesheets in Greenland and
Antarctica would remain largely stable over the coming centuries
despite global warming, but more recen
