Conceptual figure of the response of terrestrial biota to alterations to climate over time. Biotic individual species and populations respond differently from year to year and with some large events such as a decadal warming event, but rebound to their previous stable, ecosystem state. When a tipping point occurs (see text), communities may reorganize, causing changes in ecosystem properties and rates, and move to a new ecosystem state with unknown effects within a region or globally.
