The Coming Reality of Sea Level Rise: Too Fast Too Soon (Florida)

The Coming Reality of Sea Level Rise: Too Fast Too Soon (Florida)

Summary

The reality of accelerating rates of sea level rise as the result of human-induced global warming is becoming increasingly dire and urgently needs to be addressed. In 2012, the National Oceanic and Atmospheric Administration (NOAA) published United States Government sea level rise projections as a part of the National Climate Assessment (Parris et al., 2012). Those projections, which included anticipated acceleration in ice melt from Greenland and Antarctica, were for 4.1 to 6.6 feet of sea level rise by 2100. In January 2017 NOAA put out an updated projection which included an ‘extreme’ projection that was for 8.2 feet further sea level rise by 2100 (Sweet et al., 2017). The 6.6 feet of further sea level rise this century could mean 2 feet by as early as 2048 and 3 feet by 2063 (or 3 feet by 2048 with regional influences added!). A two to three foot rise of sea level will make nearly all of the barrier islands of the world uninhabitable, initiate inundation of a major portion of the world’s deltas, and make low-lying coastal zones like south and central Florida increasingly challenging communities in which to maintain infrastructure and welfare and to assure protection of life and property during hurricanes and other extreme events.

Graph of accelerating global mean sea level over the past 118 years. Sea level rise doubled after 1930 as significant ocean warming kicked in. After about 1993 the rate of rise more than doubled again as polar ice melt began, and this is – and will continue to accelerate (adapted from James Hansen and Miki Sato).
