Don’t Overthink a Climate-Change Debate

Governor Jay Inslee of Washington, whose presidential campaign is focused on climate change, started the fight a few weeks ago, when he demanded that Democrats devote one of their dozen scheduled primary debates to climate change—both to what it will mean domestically and internationally and to what candidates presume to do about it. Last week, the Democratic National Committee responded by telling Inslee that it wouldn’t hold a climate debate—and that if he appeared in one, it would block him from all future officially sanctioned debates.
