Sci., New York Univ., New York NY 10003), M.C. MacCracken, M.I. Hoffert, Northeast

A review with 18 references on techniques used to model eustatic sea level
fluctuations. A sea level rise in response to air pollution is likely, but the
magnitudes of estimates are uncertain: 8-20 cm for a scenario of low
anthropogenic greenhouse gas emission and 25-60 cm for a scenario of high
greenhouse gas emission.

Connected?" W.R. Peltier (Dept. Phys., Univ. Toronto, Toronto, Ontario M5S
1A7, Can.), A.M. Tushingham, Science, 244(4906), 806-810, May
Secular sea level trends extracted from tide gauge records of appropriately
long duration demonstrate that global sea level may be rising at a rate in
excess of one millimeter per year. When the tide gauge data are filtered,
removing the contribution of ongoing glacial isostatic adjustments to the local
sea level trend at each location, then the individual tide gauge records reveal
sharply reduced geographic scatter and suggest that there is a globally coherent
signal of strength 2.4 + or - 0.90 millimeters per year that is active in the
system. This signal could constitute an indication of global warming.
"Steric Sea Level Trends in the Northeast Pacific Ocean: Possible
Evidence of Global Sea Level Rise," R.E. Thomson (Inst. Ocean Sci., POB
6000, 9860 W. Saanich Rd., Sidney, B.C. V8L 4B2, Can.), S. Tabata, J. Clim.,
2(6), 542 ff., 1989.
Thirty-year time series of hydrographic observations from Ocean Station PAPA
and Line `P' are used to estimate secular trends in monthly mean steric sea
level heights relative to depths of 100 and 1000 decibars in the northeast
Pacific Ocean. Statistical analysis showed that steric sea levels in the
northeast Pacific are rising at approximately 1 mm yr-1 and that this increase
may be associated with a combined regional warming of the deeper waters and
dilution of the surface waters. Although the observed trends appear to be linked
to climate-induced eustatic changes in global sea level, the records are not of
adequate length or spatial coverage to rule out effects of shifting regional
