And according to that theory, it's already too late to avoid a disaster, because if it's true that our best option at the moment is to prevent CO2 emissions with something like the Kyoto Protocol, with its constraints on economic activity and its enormous cost of hundreds of billions of dollars, or whatever it is, then that is already a disaster by any reasonable measure.
已经太晚了，灾难在所难免。 因为，如果我们目前最好的选择是阻止二氧化碳排放的话， 例如通过东京议定书之类的，限制经济活动， 以及花费千亿美元等巨大的代价， 那么不管如何衡量，这就已经是一个灾难了。
