Earth's Gravity Is Being Altered By Melting Glaciers

In this image, the location of the successive calving fronts of Greenland's Jakobshavn Isbrae glacier between 1851 and 2009 are overlain on a Landsat image from July 29, 2009. The retreat of the glacier shows the substantial melt that has occurred over the time period. CREDIT: NASA/Goddard Space Flight Center Scientific Visualization Studio

Melting Glaciers Alter Earth's Gravity -- Live Science

Melting glaciers can alter Earth's gravity field, scientists have found, a discovery that is shedding light on when Greenland and Antarctica began heavily melting.

Knowing the timing of this melting could help climate scientists make better estimates of the potential sea level rise resulting from melting ice pouring off these two massive ice sheets.

My comment:
There is no details on how much of a shift in gravity has occurred. My suggestion .... compile the data between summer and winter, and look at the difference.
