Paleoclimate and the cyclical CO2 trend over 400,000 years

NOAA’s Geophysical Fluid Dynamics Laboratory has an interesting report

about Antarctic temperature and atmospheric CO2 in the Vostok ice core

showing the 100,000-year cycle of CO2 over the past 400,000 years.  A

quick view of the chart can be seen here:

The PDF report (17 pages, 2.8MB) as published in PALEOCEANOGRAPHY,

Vol. 23, PA2211, can be downloaded/viewed here:

A related report, "Ocean circulation in a warming climate" and

subtitled "Climate models predict that the ocean’s circulation will

weaken in response to global warming, but the warming at the end of

the last ice age suggests a different outcome", published in NATURE,

has its PDF (3 pages, 210kB) available here:
