A standard high school science problem is to estimate the volume of an irregular solid. There are two ways of doing this.
One is very complicated and inaccurate. The other is very simple and precise. The complicated method is to make all kinds of measurements across the surface and try to come up with a geometric model for the shape. The simple method is to put the object in a beaker of water and see how much water is displaced.
Same story with the Greenland and Antarctic ice sheets. Some scientists have engaged in a complex and flawed approach of trying to interpret gravity data. The simple and accurate way is to look at sea level data.
Any water which melts from an ice sheet runs into the sea. Thus an increase in melt rate would necessarily have to be paired with an increase in the rate of sea level rise – of course assuming that ocean temperatures have not cooled.
This has not happened. In fact, the rate of sea level rise has actually slowed over the last five years.

This simple fact is a show stopper for the theory that the rate of ice sheet melt has increased. You can’t get around it. Ocean temperatures have not cooled significantly, so the unavoidable conclusion is that ice sheet melt rates have not increased.
