Thresholds, tipping points and multiple equilibria in the Earth system

This activity will synthesize the latest insights into the existence (or lack thereof) of multiple equilibria in components of the Earth system (such as ocean circulation, ice sheets, or marine and terrestrial ecosystems).

Using paleo-evidence, as well as (transient) climate modeling, the PAGES community will develop strategies to detect and diagnose state changes and to assess the risk of them happening in the future.
