We investigate whether reported PETM paleotemperature and paleo-CO (sub 2) proxies are consistent with this hypothesis by considering the impact of large increases in CH (sub 4) emissions to the atmosphere. Significant effects on atmospheric chemistry and CH (sub 4) lifetime are seen for a range of plausible emission rates.
