> They put Miami's expected sea level rise at 0 to 1 feet over the next century That's a false description of what NOAA says. The sea level trend is an instantaneous rate, not a projection of any sort.
“The relative sea level trend is 2.39 mm/year with a 95% confidence interval of +/- 0.43 mm/year based on monthly mean sea level data from 1931 to 1981 which is equivalent to a change of 0.78 feet in 100 years.”
That's right. It's an instantaneous rate. The instantaneous rate is constantly increasing. It's not a forecast. What's hard to understand about this?
