|a Global sea level rise (SLR) has been a persistent trend
for decades. It is expected to continue beyond the end
of this century, which will cause significant impacts
in the United States (US). Over eight million people
live in areas at risk to coastal flooding, and many of
the nation’s assets related to military readiness, energy,
commerce, and ecosystems are already located at or
near the ocean.
Past trends provide valuable evidence in preparing
for future environmental change but, by themselves,
are insufficient for assessing the risks associated with
an uncertain future. For example, a number of recent
studies project an increase in the rate and magnitude
of global SLR. The US Congress recognizes the need
to consider future trends in the Global Change
Research Act (USGCRA), which calls for a National
Climate Assessment (NCA) every four years. This
report provides a synthesis of the scientific literature
on global SLR at the request of a federal advisory
committee charged with developing the next NCA.
This report also provides a set of four global mean
SLR scenarios to describe future conditions for the
purpose of assessing potential vulnerabilities and
impacts.
A wide range of estimates for future global mean
SLR are scattered throughout the scientific literature
and other high profile assessments, such as previous
reports of the NCA and the Intergovernmental Panel
on Climate Change (IPCC). Aside from this report,
there is currently no coordinated, interagency effort
in the US to identify agreed upon global mean SLR
estimates for the purpose of coastal planning, policy,
and management. This is an important gap because
identifying global mean SLR estimates is a critical
step in assessing coastal impacts and vulnerabilities.
At present, coastal managers are left to identify global
SLR estimates through their own interpretation of
the scientific literature or the advice of experts on
an ad-hoc basis. Yet, for a great majority of the US
coastline, relative sea level (RSL)1 has been rising over
the past 60 years, consistent with the global trend. |
