Antarctic Ice - What's Going on?

Recent news has reported that large losses of ice have ocurred in Antartica during the last three years. A TCS article analyzes recent studies and concludes that it is impossible to identify a trend in short term studies due to substantial variations from year to year.

There is nothing inherently noteworthy about the results of this three year study of Antarctic ice trends. This is not to disparage the scientific work of Velicogna and Wahl. It is to suggest that their paper serves more as a initial investigation into some of the applications of observations of gravitational variations, rather than bearing any relevance to the issue of global climate change and its implications.
