Earth distorted because gravity changes?

The rapid melting of ice in the Arctic caused a "distortion" effect on Earth's gravity, NASA announced.

Data on global temperatures over the past 160 years have shown that the Arctic is warming rapidly. The rapid melting of ice has caused a 'distortion' effect on Earth's gravity and this is evident from NASA's GRACE satellites.

NASA said that Grace twin satellites can accurately measure the melting of glaciers in Greenland with high accuracy. From space, the two satellites will record changes in their flight routes, thus detecting extremely small changes of gravity due to melting ice which will cause the Earth's mass to decrease slightly.

Specifically, Greenland Ice Island has faced a "light" of 240 gigatons in the period from 2002-2011. This phenomenon has caused the sea level to rise by 0.7mm annually.

'When the mass of the Greenland ice shelf changes, so does gravity,' explained Dr. Frank Flechtner of the German Earth Science Research Center GFZ. 'The new study incorporates the latest, most comprehensive ground and ocean temperature database over the past 160 years'.

On this basis, people can draw a clearer picture of Earth's climate change during that time.
