Bintanja, R., R.S.W. van de Wal, and J. Oerlemans. 2005.
Modelled atmospheric temperatures and global sea levels
over the past million years.
Nature, Vol. 437, pp. 125-128, 1 September 2005.
doi:10.1038/nature03975
Marine records of sediment oxygen isotope compositions show
that the Earth's climate has gone through a succession of
glacialand interglacial periods during the past million years.
But the interpretation of the oxygen isotope records is
complicated because both isotope storage in ice sheets
and deep-water temperature affect the recorded isotopic
composition. Separating these two effects would require
long records of either sea level or deep-ocean temperature,
which are currently not available. Here we use a coupled model
of the Northern Hemisphere ice sheets and ocean temperatures,
forced to match an oxygen isotope record for the past million
years compiled from 57 globally distributed sediment cores,
to quantify both contributions simultaneously. We find that
the ice-sheet contribution to the variability in oxygen isotope
composition varied from ten per cent in the beginning of glacial
periods to sixty per cent at glacial maxima, suggesting that
strong ocean cooling preceded slow ice-sheet build-up.
The model yields mutually consistent time series of continental
mean surface temperatures between 40 and 808 N, ice volume
and global sea level. We find that during extreme glacial stages,
air temperatures were 17 +/- 1.8C lower than present, with a
120 +/- 10m sea level equivalent of continental ice present.
STUDY NOTES: Modelled reconstructions of surface air temperature, ice volume,
and sea level derived from marine benthic oxygen isotopes (LR04 stack)
for the past one million years.
The reconstructed atmospheric surface air temperatures apply to
all subarctic to arctic land masses (including continental shelves)
north of about ~45N.
