Has anyone researched the possibility that Greenland Ice Cap covers a large Lake?

I also thought I read somewhere that the Ice Cap on Greenland is causing the land to depress from the weight of the ice, but I can't find it this morning.

Answer 1

I do not think any large lakes have been discovered under the Greenland Ice cap. For the most part Greenlands ice thickness is around 2 km. thick. Take lake Vostok under Antarctica for instance is located under 4 kilometers of ice.

Answer 2

There could be a lake because they just discovered a hot spot under the ice! Could you imagine Greenland ice (it is only about 110,000 years old because it was too warm for ice to form between 130,000-110,000BC) melting because of a possible natural volcano? What will the AGW supporters do? I better go to the store and buy more purple Kool Aid.

Answer 3

Yes this happens. Many parts of the Earth are still rebounding from the loss of weight of the last ice age.

Norway is growing 1 - 2 mm per year now, returning to normal from the last time glaciers covered the north.

This process is called post glacier rebound
