However, there is an increasing body of literature that has found continued, longer-term responses of ecosystems to climate change, so-called 'committed changes', that arise from lags that exist in many systems. Many processes in ecosystems take more than a few decades to quasi-equilibrate to environmental changes. Therefore, the trends of changing vegetation cover identified in simulations of transient warming continue to show up in simulations that hold climate change at low levels of warming  . Such changes, which could tip ecosystems into an alternative state, could also be triggered by a 'warming overshoot' if global warming were to exceed a certain threshold, even if mean temperatures afterwards decline again .
