No acceleration in the historical trend. No correlation with CO2 increase. End of story.

We have been studying climate change and potentially associated sea level changes resulting from melting ice and warming oceans for a half century, says CFACT.
In the 1970s our primary concern was global cooling and an advancing new ice age.
Many believe that increasing quantities of carbon dioxide in our atmosphere could result in rising levels of the sea in general. The record does not show this to be true.
There is no evidence whatever to support impending sea-level-rise catastrophe or the unnecessary expenditure of state or federal tax monies to solve a problem that does not exist.
The National Oceanographic and Atmospheric Administration (NOAA) has updated its coastal sea level tide gauge data which continue to show no evidence of accelerating sea level rise.
These measurements include tide gauge data at coastal locations along the West Coast, East Coast, Gulf Coast, Pacific Ocean, Atlantic Ocean and the Gulf of Mexico, as well as seven Pacific Island groups and six Atlantic Island groups, comprising more than 200 measurement stations.
The longest NOAA tide gauge record on coastal sea level rise measurements is in New York at the Battery, with its 160-year record which is shown below with a steady rate of sea level rise of 11 inches per century.
A slightly slower rate of sea level rise occurs at nearby Kings Point, New York, whose 80-year record also appears below.

[The analysis concludes…]
The data and projected trends for these ten well-documented coastal cities point to three conclusions:
1 – There has been no dramatic sea level rise in the past century, and projections show no dramatic rise is likely to occur in the coming century.
2 – There is no evidence to indicate the rate of sea level rise or fall in any of the areas of this study will be substantially different than has been the case over the past many decades.
3 – There is no correlation between CO2 concentrations in the atmosphere and sea level rise. The steady but modest rise in sea level predated coal power plants and SUVs, and has continued at its same pace even as atmospheric CO2 concentrations rose from 280 parts per million to 420 parts per million today .
