The multi-millennial sea-level commitment of global warming of
Levermann et al.(PNAS 2013)
Sea-level contribution from (a) ocean warming, (b) mountain glaciers, (c) Greenland, (d) Antarctica and
(e) the total sea-level commitment after 2000 years (Levermann et al. (2013).
The multi-millennial sea-level
commitment of global warming of Levermann
et al.(PNAS 2013) Future sea-level commitment: For each
degree of warming above pre-industrial, sea-level will rise
by about 2.3m within a period of 2000 years (Levermann et
al. (2013). For projections of the 21st century we propose
a linear response function
R(t) = Γ⋅tα with positive
α for Antarctic ice discharge from surface warming &
negative α for other contributions (Winkelmann & Levermann,
2012).
