Why does the Earth stay habitable?

From UCL, London, UK
The Earth has been inhabited by life for over 3.5 billion years. This requires that the climate has stayed within certain temperatures for this time - effectively meaning that the climate has been incredibly stable for most of Earth’s existence. This cannot be a coincidence, and there must be processes that stabilise the climate. While there are several theories, until very recently, none have been demonstrated as actually operating, and, if they do, how rapidly they can affect climate. This talk will examine evidence for climate stabilisation mechanisms from the geological record.
