Average sea level rise has been very steady for the last 100 years at about 2 mm/year, which is comparable to the rise recorded by CU over the last five years. That is at least 15-30X too low to reach Dr. Hansen’s 3-6 metre estimate – shown in green.
The blue line shows atmospheric CO2 during the same period. CO2 has risen substantially during the last 50 years, but the rate of sea level rise has been constant.
Conclusions : Sea level rise has nothing to do with changes in atmospheric CO2, and Hansen’s forecasts show no sign of being in the ballpark.
