[On the security risks of climate change] The classic definition [of state security] has been around conflict—threats to human life from armed aggression—which includes intrastate components such as dissident groups and civil war, and then, of course, when states go to war with each other.... [But climate change may induce conflict] to happen in places that are already living on the edge.
[On climate change leadership] Every proposal we make in cutting emissions needs to be evaluated through the lens of followership. Are things that we do near home or in collaboration with other countries … likely to lead other emitters around the world to reduce their emissions?

[On Washington governor and U.S. presidential candidate Jay Inslee's recently released climate plan] It is not clear to me that supply chains could meet the need for all new light- and medium-duty vehicles and buses, along with all new buildings, to be zero-emission by 2030. [Yet], no other candidate is devoting this much attention to the climate issue.
