The term “dismal theorem” refers to the idea that:选项：
A.potentially catastrophic outcomes should be valued to negative infinity. B.moral considerations related to future climate change warrant low discount rates. C.the probability of total civilizational collapse causes the discount rate to increase dramatically.解释：
A is correct. The dismal theorem suggests that standard cost–benefit analysis is inadequate to deal with the potential downside losses from climate change. However small the probability, as long as we cannot completely rule out scenarios of climate-induced civilizational collapse, their expected value must be thought of as being equal to negative infinity. Economist Nicholas Stern argued that moral considerations warrant using a low discount rate when assessing future climate damages to place adequate value on the lives and welfare of future generations.The term “dismal theorem” refers to the idea that:
