There are many people who still do not believe in the whole global warming issue or the fact the we have anything to do with it. Well recent studies show that since 2003 over two trillion tons of ice has melted from Greenland, Alaska and Antarctica. And if you think that is a lot scientist say that this is simply the beginning. More than half of this loss comes from Greenland and a NASA geophysicist claims that the water melted from Greenland would fill up about 11 Chesapeake Bays. You can find a excerpt from MSNBC as well as more information below.

“The news was better for Alaska. After a precipitous drop in 2005, land ice increased slightly in 2008 because of large winter snowfalls, Luthcke said. Since 2003, when the NASA satellite started taking measurements, Alaska has lost 400 billion tons of land ice.

In assessing climate change, scientists generally look at several years to determine the overall trend.

Melting of land ice, unlike sea ice, increases sea levels very slightly. In the 1990s, Greenland didn’t add to world sea level rise; now that island is adding about half a millimeter of sea level rise a year, NASA ice scientist Jay Zwally said in a telephone interview from the conference.

Between Greenland, Antarctica and Alaska, melting land ice has raised global sea levels about one-fifth of an inch in the past five years, Luthcke said. Sea levels also rise from water expanding as it warms.”
