Another question is that when it is gone, what will be left? Will Greenland truly become a green land?

What most people don't know is, that below the heavy ice is a huge cavity close to 1 miles deep at the mid. Remove the ice - and we have a huge lake!

Over time after the ice is gone, that depressed land mass will slowly start rising again, just like the coasts of Sweden are still on the rise after the glacial ice sheet all gone aro 10,000 years ago.

Back in the 1960s the thickness of the ice was measured and the bottom cavity profile roughly profiled using looking-down microwave radar style equipment mounted under aircrafts covering the land latitude by latitude. The transmitting frequency was optimized for ice penetration while still being reflected from the solid bottom below the ice.

Our professor was a participant in this project and we, his engineering students, did the calculations based on the measurement raw data provided.

"This is getting pretty mind boggling."

It is; you should get a job as a spinning top. You are very good at it.

"It also says that it is nearly impossible to stop."
Nuclear winter, industrial-strength carbon sequestration, or massive problematic geoengineering schemes are about the only ways. It will, of course, melt faster as the planet warms, so we should prolly keep the warming down as best we can.

The other end of the world has a lot more ice. If it all melts, sea levels will rise about 200 feet.
