|a Climate warming does not force sea-level rise (SLR) at the
same rate everywhere. Rather, there are spatial variations of
SLR superimposed on a global average rise. These variations
are forced by dynamic processes, arising from circulation
and variations in temperature and/or salinity, and by static
equilibrium processes, arising from mass redistributions
changing gravity and the Earth’s rotation and shape. These sealevel
variations form unique spatial patterns, yet there are very
few observations verifying predicted patterns or fingerprints.
Here, we present evidence of recently accelerated SLR in a
unique 1,000-km-long hotspot on the highly populated North
American Atlantic coast north of Cape Hatteras and show
that it is consistent with a modelled fingerprint of dynamic
SLR. Between 1950–1979 and 1980–2009, SLR rate increases
in this northeast hotspot were [approximately]3–4 times higher than the
global average. Modelled dynamic plus steric SLR by 2100
at New York City ranges with Intergovernmental Panel on
Climate Change scenario from 36 to 51 cm (ref. 3); lower
emission scenarios project 24–36 cm (ref. 7). Extrapolations
from data herein range from 20 to 29 cm. SLR superimposed
on storm surge, wave run-up and set-up will increase the
vulnerability of coastal cities to flooding, and beaches and
wetlands to deterioration. |
