Not exact matches
During the last
deglaciation, and likely also the three previous ones, the onset of warming at both high southern and northern latitudes preceded by several thousand years the first signals of significant
sea level increase resulting from the melting of the northern ice sheets linked with the rapid warming at high northern latitudes (Petit et al., 1999; Shackleton, 2000; Pépin et al., 2001).
Remember that there was about 10 times the amount of ice on the Northern hemisphere
during the multimeter
sea level rise intervals of the
deglaciation, so there was a larger reservoir to work with.
# 39 Remember that there was about 10 times the amount of ice on the Northern hemisphere

Since the volume of ice at risk under BAU is within a factor of two of the volume of ice at risk
during a
deglaciation under orbital forcing, while the forcing is much more rapidly applied under BAU, looking at
sea level rise rates in the paleo - record might actually be considered a search for lower limits on what to expect if reticence did not run so strongly in our approach.
Ultimately, we would probably hit 20 inches a decade, the rate at which
sea levels rose
during the last
deglaciation.
During deglaciation between 19,000 and 8,000 years ago,
sea level rose at extremely high rates (Cronin, 2012).
Here, we review terrestrial evidence for changes in ice geometry that occurred in the Ross
Sea sector of Antarctica at the Last Glacial Maximum (LGM) and
during subsequent
deglaciation.
A simulation of the Siberian continental margin after glacial
sea level drop and exposure to the cold atmosphere, snapshot as
sea level rises
during the
deglaciation.
«
During the penultimate
deglaciation, there was much more rapid and sustained increase in
sea level compared to the last
deglaciation.
The final 80 m of
sea level rise took only ~ 2 ka
during the penultimate
deglaciation...»
During an interval when
sea level is forced upward from a major low stand by a Milankovitch response acting either alone or in combination with an internally driven, higher - frequency process, ice sheets grounded on continental shelves become unstable, mass wasting accelerates, and the resulting
deglaciation sets the phase of one wave in the train of 100,000 - year oscillations.
