Not so much about the amount of change, but the accelerating speed of change.
>>An international team of scientists from over 40 organizations around the world has completed the most comprehensive assessment of how Antarctica’s ice mass is changing – and as expected, the results are worrying. The Ice Sheet Mass Balance Inter-comparison Exercise (IMBIE) shows that the rate of ice loss – and the resulting sea level rise – has tripled since 2012, compared to a more steady rate over the last 25 years.>>

We can’t get a really reliable measurement of Antarctic melting rates until the satellite IceSat-2 goes up. That’s due for launch September 2018.
The old IceSat is actually pretty unreliable – I compared it with other measurements of Antarctic ice-sheet altitudes and there were substantial errors. Most of the other satellites that have looked at ice sheet altitudes have used binocular vision, which fails spectacularly on featureless terrain such as ice. Also, most other satellites haven’t gone to high latitudes, they can only see what is happening around the fringes. The Japanese spacecraft data has the best resolution but is too expensive to buy in bulk for any but billionaires, even ten square km of data costs hundreds of thousands of dollars to purchase.
To cut a long story short, wait until IceSat 2. We’ll have extremely reliable values then.
