Abstract:
The Earth has been inhabited by life for up to 85% of its existence. For that life to survive, something must have prevented the climate from becoming too extreme or even going runaway in either direction. For several decades, the community has generally assumed that the weathering thermostat is the mechanism that stabilises the climate. However, there is very scant evidence from the geological record that the thermostat really exists, or indeed the rates and timescales over which it might operate. This talk presents new data from several climate change events.
