潜在的气候临界点对社会构成越来越大的风险,政策要求改善对它们的预测。卫星遥感可在查明和预测各种规模的倾翻现象方面发挥独特的作用。在卫星记录太短而无法对临界点进行时间预警的情况下,补充性空间指标可以利用遥感数据特殊的时空覆盖范围来探测脆弱系统不断变化的复原力。将地球观测与地球系统模型相结合,可以改善对临界点、其相互作用和潜在的临界级联的基于过程的理解。这种高分辨率传感可以支持跨尺度的气候临界点风险管理。气候变化可能使地球系统的关键部分超过临界点,造成大规模、突然和/或不可逆转的变化,危害社会。在这里,作者认为,卫星遥感可以在帮助管理这些深刻的风险方面发挥独特的作用,通过提供更好的跨尺度临界点预警。
Potential climate tipping points pose a growing risk for societies, and policy is calling for improved anticipation of them. Satellite remote sensing can play a unique role in identifying and anticipating tipping phenomena across scales. Where satellite records are too short for temporal early warning of tipping points, complementary spatial indicators can leverage the exceptional spatial-temporal coverage of remotely sensed data to detect changing resilience of vulnerable systems. Combining Earth observation with Earth system models can improve process-based understanding of tipping points, their interactions, and potential tipping cascades. Such fine-resolution sensing can support climate tipping point risk management across scales. Climate change could drive critical parts of the Earth system past tipping points, causing large-scale, abrupt and/or irreversible changes that harm societies. Here, the authors suggest that satellite remote sensing can play a unique role in helping manage these profound risks, by providing improved early warning of tipping points across scales.
