I have written about the lack of sea level rise multiple times on this blog starting with this article on a Pacific Institute study of Bay Area Sea Level Rise for the California Energy Commission's Climate Change Center Report Series.
The Pacific Institute conducted a study of sea level rise and it's impact on the Bay Area. They were to evaluate the risk of future sea level rise on the California coast and the San Francisco Bay. The study was published as part of the California Energy Commission's Climate Change Center Report Series. This series is to provide California citizens ready access to climate change research.
I found the Pacific Institute report writers had truncated the data, since the full data set did not support their position of accelerating sea level rise. This resulted in a heated exchange with one of the authors Dr. Peter Glick. I could not find any evidence of any acceleration in sea level rise, in fact is was decelerating. But, I was blown off since I did not have a PHd and a peer reviewed analysis. How we have some peer reviewed evidence there is no sea-level acceleration.
Sea-Level Acceleration Based on U.S. Tide Gauges and Extensions of Previous Global-Gauge Analyses
Without sea-level acceleration, the 20th-century sea-level trend of 1.7 mm/y would produce a rise of only approximately 0.15 m from 2010 to 2100; therefore, sea-level acceleration is a critical component of projected sea-level rise. To determine this acceleration, we analyze monthly-averaged records for 57 U.S. tide gauges in the Permanent Service for Mean Sea Level (PSMSL) data base that have lengths of 60–156 years. Least-squares quadratic analysis of each of the 57 records are performed to quantify accelerations, and 25 gauge records having data spanning from 1930 to 2010 are analyzed. In both cases we obtain small average sea-level decelerations. To compare these results with worldwide data, we extend the analysis of Douglas (1992) by an additional 25 years and analyze revised data of Church and White (2006) from 1930 to 2007 and also obtain small sea-level decelerations similar to those we obtain from U.S. gauge records.
This paper is being discussed at Watts Up With That, with links to the full report.
I found this comment by David Archibald at WUWT most interesting. Is the current data inconsistent with the all the global warming mantra?
On the subject of sea level, the University of Colorado sea level people have not updated the data on their site. The last data point is 2010.7415 which is in July last year, over seven months ago. Perhaps the data since then is inconvenient, or perhaps the Colorado people have just lost interest. Could someone else please get the Jason data and make it publicly available.
Exit Question: Is sea-level rise a real threat to California, or is it just a global warming scare by rent seeking scientist looking for more research funding?
