New Sea Level Rise projections

Real Climate comments on a recent expert panel that has described the best understanding of what sea level rise is expected to bring to our shores. The fascinating thing that it includes are 2 different measures of what to expect depending on the human response to climate change:

With successful, strong mitigation measures, the experts expect a likely rise of 40-60 cm in this century and 60-100 cm by the year 2300. With unmitigated warming, however, the likely range is 70-120 cm by 2100 and two to three meters by the year 2300.

The difference between the strong mitigation and unmitigated is nearly double. It really speaks to both the inevitability of impacts and the value of intervention. The commenters are more interesting than on many blogs. Check out comment #40 which speaks to design responses. BTW, The original paper on the panel is written by Rutgers' Ben Horton.
