Follow the Science: Seas Rising 20 Times Slower than the Media Claim

by J. Taylor, Apr 13, 2021 in ClimateRealism


According to NASA and NOAA satellite instruments, sea level is rising at a mere 3 millimeters per year, which is a pace of just under one foot per century. (Note, the NASA/NOAA-reported 3.3 mm/year rise in Global Mean Sea Level includes a 0.3 mm “adjustment” that accounts for land rising as glaciers melt. The sea-level rise in relation to coastal shorelines is therefore 3.0 mm/year.) Moreover, the satellite measurements show no significant acceleration during recent decades in the pace of sea-level rise.

Given that seas are rising at a pace of merely one foot per century, which is little if any faster than the pace of sea-level rise throughout the global warming of the 1800s and 1900s, it is almost certain that seas will not rise 20 feet during the next 100 to 200 years. It is also almost certain that seas will not rise two feet during the next 20 years.
