The Day After Tomorrow

In 1988, Dr. Hansen forecast that Manhattan would be partially submerged by now due to CO2.

He must believe that there is a strong relationship between sea level rise rates and CO2. That is a simple theory to test, because NOAA keeps sea level data for New York. I plotted their entire data set vs atmospheric CO2 for the same dates.

As you can see, there is no correlation between sea level rise rates and CO2. The fastest sea level rise occurred around 310 ppm, barely above pre-industrial levels.

When Dr. Hansen made that prediction, Al Gore had not yet invented the Internet – so it was more difficult to get data.
