This is confirmed by gravity satellite measurements over the past 9 years which find that the
rate of ice mass loss has doubled over the last 9 years.

Spread of ice mass loss into northwest Greenland observed by GRACE and GPS, Geophys.
Thanks to GRACE satellite monitoring, there is a good gravity
record of ice mass loss from Greenland from the period 2002 - present.
The
rate of ice mass loss in the Russian Arctic has nearly doubled over the last decade when compared to records from the previous 60 years, a new study shows.
Velicogna, I. Increasing rates
of ice mass loss from the Greenland and Antarctic ice sheets revealed by GRACE.
In 1996, the rate
of ice mass loss had increased to 97 gigatonnes per year.
