An iceberg drifts in the iceberg graveyard near the Weddell Sea
"Back in the early 1990s," says Jay Zwally, a glaciologist with NASA's Goddard
Space Flight Center, and the principal scientist for the agency's ICEsat
orbiter, "Greenland was losing ice at the margins but gaining in the center. It
was in balance." Recently, though, NASA's gravity-mapping satellite, known as
GRACE, the Gravity Recovery and Climate Experiment, has shown a net loss of
about a Lake Erie's worth of ice every two years.
In Antarctica, where many glaciers flow, not directly into the sea but into
giant, floating ice shelves, it's the thinning or total collapse of the shelves
— something that's been happening with increasing frequency
According to a new report in Nature, glaciers are getting thinner all
around the perimeter of Greenland, and in western Antarctica as well.
Just can't imagine if all glaciers melt all of a sudden. yes it's so hot that I guess before they melt I'll melt first. will you too?
