Hold that tiger! Sea level rise far under experts' predictions

San Francisco sea level rise since 1854; highest in 1983

John Wiesner again cast cherry-picking “stones” in a purportedly scientific letter remarkably devoid of science. He said I avoid “an obvious upward sea level trend line”, although in previous letters I’ve noted that San Francisco sea level has risen 4.2” since 1854. My point is simple: since 1983, with unremitting atmospheric CO2 increases, sea levels for six West Coast cities have fallen, not risen.

CO2 up, sea level down. Simple, right?

In previous letters, I've illustrated ad nauseam that sea level rose over 400 feet following the Ice Age 12,000 years ago, that sea levels were higher during the four previous warming periods of the past 10,000 years – sea levels during the Holocene Climate Optimum (8,000-4,000 years ago) were up to ten feet higher – and that current sea level rise is a natural rebound from the drop in sea level during the Little Ice Age (1450-1850AD). 
Mr. Wiesner said I refuse to fit an RMS trend line. Although I can’t find such a refusal, I wonder why Mr. Wiesner hasn’t done it himself? Anyhow, I’m pleased to comply. For San Francisco, the mean sea level trend is 2.01 millimeters/year with a 95% confidence interval of +/- 0.21 mm/yr. The other five cities’ trends are here. Projected increases per century: a modest 1.5” to 8”.
Warmists refuse to debate previous climate change with me; in fact, they seem to avoid all debate. While on our Antarctic trip, James “Chasing Ice” Balog and Dr. Bindschadler both publicly avoided debating previous climate change. You too, Mr. Wiesner?

For Brendan Mobert: I appreciate your comments (Alice agrees with you), but the “other side” owns global warming news (for instance, ICO), and mine doesn’t, so while I’m “riding the tiger”, I can’t get off even though I’ve beaten it nearly to death.
