|a The coastal zone has changed profoundly during
the 20th century and, as a result, society is becoming
increasingly vulnerable to the impact of sea-level rise and
variability. This demands improved understanding to
facilitate appropriate planning to minimise potential losses.
With this in mind, the World Climate Research Programme
organised a workshop (held in June 2006) to document
current understanding and to identify research and observations
required to reduce current uncertainties associated
with sea-level rise and variability. While sea levels have
varied by over 120 m during glacial/interglacial cycles,
there has been little net rise over the past several millennia
until the 19th century and early 20th century, when geological
and tide-gauge data indicate an increase in the rate of sealevel
rise. Recent satellite-altimeter data and tide-gauge data
have indicated that sea levels are now rising at over 3 mm
year-1. The major contributions to 20th and 21st century sealevel
rise are thought to be a result of ocean thermal expansion
and the melting of glaciers and ice caps. Ice sheets are
thought to have been a minor contributor to 20th century sealevel
rise, but are potentially the largest contributor in the
longer term. Sea levels are currently rising at the upper limit
of the projections of the Third Assessment Report of the
Intergovernmental Panel on Climate Change (TAR IPCC),
and there is increasing concern of potentially large ice-sheet
contributions during the 21st century and beyond, particularly
if greenhouse gas emissions continue unabated. A suite
of ongoing satellite and in situ observational activities need
to be sustained and new activities supported. To the extent
that we are able to sustain these observations, research programmes
utilising the resulting data should be able to
significantly improve our understanding and narrow projections
of future sea-level rise and variability. |
