Global Warming Will Not Raise Sea Level
S. Fred Singer
Global sea level (SL) has undergone a rising trend for at least a century; its cause is believed to be unrelated to climate change . We observe,however, that fluctuations (anomalies) from a linear SL rise show a pronounced anti-correlation with global average temperature--and even more so with tropical average sea surface temperature. We also find a suggestive correlation between negative sea-level rise anomalies and the occurrence of El Nino events. These findings suggest that--under current conditions-- evaporation from the ocean with subsequent deposition on the ice caps, principally in the Antarctic, is more important in determining sea-level changes than the melting of glaciers and thermal expansion of ocean water. It also suggests that any future moderate warming, from whatever cause, will slow down the ongoing sea-level rise, rather than speed it up. Support for this conclusion comes from theoretical studies of precipitation increases  and from results of General Circulation Models (GCMs) [3,4]. Further support comes from the (albeit limited) record of annual ice accumulation in polar ice sheets .
