And one issue that is underestimated in the IPCC models of 2001 report is in my opinion the rise in sea levels. The figures below are from The Future Oceans - Warming Up, Rising High, Turning Sour; WBGU 2006

The measured sea level rise is above the predictions of the IPCC models.

Yes, sea levels are rising a lot faster than the models predicted even a year ago.  

I think we are going to have to retreat from the coasts.  Something to keep in mind, before spending billions of dollars on new infrastructure (new transmission lines, banks of wind turbines, new rail lines, etc).

James Lovelock, in "The Revenge of Gaia," says that atmospheric conditions now seem to him to be equivalent to those in the Eocene period, and his prediction is for temperatures 5 degrees centigrade warmer than it is now. If he is correct (his forecasts are gloomier than most), based on your graph, we may be looking at 75m or 80m rise in sea levels. Since the relationship looks linear, we may expect a considerable rise in sea level well before we get to +5 degrees.
