Dr. Archer has worked on the ongoing mystery
of the low atmospheric CO2 concentration during glacial time 20,000 years ago, and on the
fate of fossil fuel CO2 on geologic time scales in the future, and its impact on future ice age cycles, ocean
methane hydrate decomposition, and coral reefs.
Another approach is to «grow» the sediment column through geologic time to obtain an initial condition for a climate change perturbation scenario (Archer et al., 2012), but uncertainties in various model parameters, such as the
methane production rate and the
fate of bubbles in the sediment column, prevent a well - constrained model forecast
of the
methane hydrate response to climate warming.
