Simply stated: Slim to none.
Experts in sea level research did a focused analysis on the predicted sea level projections for California by activist groups. These groups are suggesting that sea level rise could be as much as 3 meters by year 2100 due to human CO2 emission release into the atmosphere.
This peer-reviewed study - from experts not associated with an activist agenda group(s) - determined that the alarmist predictions of dramatic increases of California sea levels 'hold no water'.
This chart is from their study analysis, along with the below stinging rebuttal to the activist groups.
"In summing up these and other of their several findings, Parker and Ollier write that "the evidences from real sea level measurements do not support the IPCC models or the even more alarming predictions [made by the National Research Council and California Ocean Science Trust]. The latter, "they continue, "are founded on pure speculation, constructed on unproven assumptions, and do not provide a suitable basis for use in planning or policy making.""
