Whoops! Wrong sign!

Bombshell conclusion – new peer reviewed analysis: “worldwide-temperature increase has not produced acceleration of global sea level over the past 100 years” | Watts Up With That?: "J. R.

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."
Has it ever occurred to these emotional basket cases that raising the average temperature of the Antarctic from -50C to -45C -- even if it were to be accomplished which ain't happening folks -- is more than just a few marbles shy of a melt-o-rama?
