Our other key finding is that a sudden transition from the regular cold state to the hot metastable state can be triggered by realistic climate patterns alone, including summer heat waves and global warming scenarios..

If the atmospheric temperature increases by the same amount but at a slower rate, bioactive peat soil remains in the regular cold state and never transitions to the hot metastable state...

This is concerning, as it could kick off a vicious cycle: The gigatons of carbon released from ancient peat soils into the atmosphere are likely to make the climatic changes even worse, which means more fires, so more extreme weather, and so on...

Indeed, zombie fires are an example of a rate-induced tipping point, where a system fails to adapt to too-fast changes in external conditions and transitions from its regular state to a different, often undesired state..

It is possible that the contemporary climate is approachingor has already exceededdangerous rates of change for certain natural system, such as bioactive peat soils, which could explain the recent increase in zombie fires...
