While I agree that actions to address climate change are urgently needed, the worst action that a voter can take is to cast a vote that makes it more likely that a climate change denier or his down-ticket, like-minded candidates are elected. I find disturbing that you imply that atmospheric scientist Michael Mann endorses Jill Stein by giving the advice, “Vote climate from the top of the ticket all the way down. ” Professor Mann surely realizes that there is no time left to waste votes. Hillary Clinton's Florida speech on climate change was articulate and forceful. She is the right candidate in this presidential election.
