Get the facts right Andrew
The statement in this article that these new results rely on just two years of data is, quite simply, false.
If you wish to know why then listen to my Today interview (http://news.bbc.co.uk/today/hi/today/newsid_9744000/9744378.stm) where I state that the trends are derived by combining CryoSat-2 volume estimates with earlier (2003-2008) volume estimates from NASA's ICESat mission [Kwok, JGR, 2009].
I also state that one must be cautious in extrapolating these trends forwards.
