The latest research indicates a dramatic increase in the rate of melting in Greenland. NASA research in 2001 was recording a drop in height at the ice sheet margins of 1 metre per year. Now the latest research is recording drops as much as 10 metres per year - a ten fold increase. Sadly, at this rate global warming skeptics will not need to wait long to be proved wrong.
See my previous posts for more information and photos of the melting of Greenland.
