Paleoclimate Reconstruction
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
vice versa. The common answer is that there is an
(unspecified) feedback mechanism.
