|a Current global warming necessitates a detailed understanding of
the relationships between climate and global ice volume. Highly
resolved and continuous sea-level records are essential for quantifying
ice-volumechanges.However, an unbiased study of the timing of
past ice-volume changes, relative to polar climate change, has so far
been impossible because available sea-level records either were dated
by using orbital tuning or ice-core timescales, or were discontinuous
in time. Here we present an independent dating of a continuous,
high-resolution sea-level record1,2 in millennial-scale detail throughout
the past 150,000 years. We find that the timing of ice-volume
fluctuations agrees well with that of variations in Antarctic climate
and especially Greenland climate.Amplitudes of ice-volumefluctuations
more closely match Antarctic (rather than Greenland) climate
changes. Polar climate and ice-volume changes, and their rates of
change, are found to covary within centennial response times.
Finally, rates of sea-level rise reached at least 1.2mper century during
all major episodes of ice-volume reduction. |
