Satellite technique to more accurately measure Antarctica ice movement

An interesting technique is now being used to measure the ice movement across the Antarctica continent, revealing a more accurate picture of what is happening over time. Check out this article and the map that has been produced. In the past, other techniques had large uncertainties, and therefore a range of best guesses of what would result over time. This satellite technique has greatly reduced uncertainties and scientists should be able to better predict and monitor what is going on with climate change and polar warming.
