As a result of widespread reliance on the precautionary principle, doomsday scenarios have come to dominate discussion of climate change. It is easy to imagine disasters so severe that drastic action to prevent them would be reasonable, and advocates of drastic action can easily scare the public with imagined disasters.
由于人们对“预防性原则”的普遍依赖，世界末日的假想情节已经占据了气候变化议题的所有内容。人们可以轻易地想象出气候灾难是如此严酷，因此采取激进行动来阻止它们也是合情合理的，而激进行动的鼓吹者仅靠假象的灾难就能够轻易地对公众加以恐吓。因为没有人对引起气候变化的原因有足够了解，并进一步证明假想中的灾难根本不可能发生。
