The virtual seminar will be held from 3:00 to 4:30 p.m. (E.T.)

Most treatments of nuclear ethics or strategy have not considered the implications of long term, large scale, or even regional, catastrophic climatic effects known as “nuclear winter” triggered by some level of nuclear weapons use. This presentation will explore if and how the potential for nuclear winter changes the legality and ethics of the threat to use nuclear weapons. It will focus on asking whether nuclear war ever could be discriminate and proportionate if it risks causing nuclear winter.  At a policy level, how should nuclear weapons states regard their arsenals if there is a significant or even a small risk that nuclear weapons use would cause such climatic disruption effects?
