Stefan Rahmstorf of the University of Potsdam, Germany has calculated that sea level rise will be substantially higher than predicted recently and that even for low-emissions scenarios the best estimate for sea level rise is 1 meter by 2100. Sea level rise may well exceed one meter by 2100 if emissions continue unabated. For the worst-case scenario, the new calculation predicts sea level rise of 1.80 meters by 2100. There remain uncertainties, of course, but my pessimism for the coastal area of Virginia, USA, lies in the belief that emissions will continue unchanged.
It will be good for economy-stimulating people to delay bridge and highway building along our coast and to concentrate expending funds inland. The roads will be under water! Build ferries!
