Description:
The hottest topic for those interested in the earth's carbon cycles is the change
in atmospheric CO2 content between glacial and interglacial time. What caused it? What is its
role in glacial cycles? We evaluate here the hypotheses that have been put forward to explain
the CO2 change with evidence from deep sea sediments. We conclude that all the hypotheses
have serious drawbacks and that much effort will have to be expended in gathering more data
from ice cores and ocean sediments before we will be pointed toward the correct scenario.
Also, thoughtful modeling aimed at depicting the ties between pC02, 02, 13C/12C, 14C/12C, and nutrient constituents in the sea for various modes of circulation will have to be done before
the evidence from ocean cores can be properly interpreted.
