¥5. Similar questions exist about ice cores
and how representative such data might be.
What are the effects of gas diffusion in
the ice core layers?
¥6. In the
ice core (Vostok) data that Al Gore illustrates in the Inconvenient Truth, the temperature time series leads, not lags, the CO2 time series by 800 to 1000 years. What
is the causal mechanism? It would seem that
temperature increases cause CO2 release, not

an (unspecified) feedback mechanism.
