Sea level has risen about 400 feet since the last glacial maximum of ~18,000 years ago (see fig. below). Currently, sea level is rising at the rate of 1-2mm per year — and has been rising at that rate for the past several centuries. At that rate, S.L. will be about six inches higher by 2100 — a long way from Al Gore's 2006 estimate of a 20-foot rise. By choosing a short interval, 1910–1942, of certified warming, I can show the lack of any acceleration (see below).  SLR does not depend on ocean temperature — or CO2. Every one of the...
