This news is important because

1. It is the first report that in addition to Antarctica, the northern 
polar regions are losing ice.  (TMY - to my understanding).

2. The teletext brief on this which first caught my eye, quoted the figure 
of 7% rise is worldwide sea level but gave a much more startling figure. 
That the rise in global sea level in the last 100 years is 9 inches.

I cannot see that confirmed in the more detailed web reports, which sound 
as if even the Greenland data needs a lot of interpretation.

Does anyone know how hard the evidence is for a rise in global sea levels 
in the last 100 years, and what order of magnitude that is estimated to be?
