- OF GENERAL INTEREST: SEA LEVEL
Level," C. Woodroffe (Dept. Geog., Univ. Wollongong,
Wollongong, NSW 2500, Australia), Progress Phys. Geog., 17(3),
359-368, Sep. 1993.
A review examining trends in sea level over recent decades
from tide gauges; predictions of future change and the responses
of the coast; and Quaternary sea-level change. Recent analyses
appear to be reducing the magnitude of any sea-level rise to be
expected from global warming, although geographical variability
is rarely incorporated into such estimates.
Erosion--An Escalating Environmental Threat," H. Hanson
(Dept. Water Resour. Eng., Lund Univ., Box 118, S-22100 Lund,
Swed.), G. Lindh, Ambio, 22(4), 188-195, June 1993.
Coastal zones are extremely important for the development of
society, and negative impacts related to sea level change are
expected to increase as a result of climate change. Planners and
decision makers need a greater awareness of the instability of
sandy beaches and the possible impact of human activities. We
must improve our knowledge about nearshore processes and develop
methods to quantitatively determine the behavior of beaches.
Sea Level Acceleration," B.C. Douglas (Natl. Oceanog. Data
Ctr., NOAA, Washington DC 20235), J. Geophys. Res., 97(C8),
12,699-12,706, Aug. 15, 1992.
Analysis of tide gauge records since 1850 shows no evidence
for an acceleration of sea level rise in the past 100+ years that
is significant either statistically or in comparison to values
associated with global warming. Further analysis shows that tide
gauges alone cannot serve as a leading indicator of climate
change in less than several decades.
