Another article, this time by the BBC, reporting more bad news on the global warming front. Sebastian pointed this one out, so I figured I write a little about it too. Apparently the collapse is not good news as it is both an example of the rapid changes in the Antarctic as well as possibly making it easier for the glaciers and other ice flows now on land to move into the sea, possibly affecting sea levels.
Following from that thought, and regarding sea levels, it is paragraph near the end that really gets me:
Such acceleration effects were not included by the UN's Intergovernmental Panel on Climate Change (IPCC) when it made its latest projections on likely future sea level rise. Its 2007 assessment said ice dynamics were poorly understood.
I must admit that I hate reading things like this. It is just scary when, as often happens, you read about a previous worst case output or warming scenario, followed by the statement that actual CO2 output or whatever was dramatically greater again.
