Early-warning systems . The nature of Earth-system dynamics—the nonlinearities, tipping elements, thresholds/abrupt changes—strongly suggests that humanity needs a system to warn us when we are approaching such potentially catastrophic points. Indeed, the planetary boundaries approach is based directly on this feature of the Earth system. An early-warning system is a prerequisite for being able to recognize and steer away from such thresholds. Dealing with uncertainties . Each of the planetary boundaries is placed within a zone of uncertainty, some much larger than others. Although further scientific research will reduce these uncertainties in many cases, they will never be completely eliminated. In a poisonous political environment, uncertainties can be exploited as reasons for inaction, but scientists must be able to address uncertainty without being attacked. A global g...
