This is an invitation, an invitation to come to New York City. An invitation to anyone who’d like to prove to themselves, and to their children, that they give a damn about the biggest crisis our civilization has ever faced.
My guess is people will come by the tens of thousands, and it will be the largest demonstration yet of human resolve in the face of climate change. Sure, some of it will be exciting – who doesn’t like the chance to march and sing and carry a clever sign through the canyons of Manhattan? But this is dead-serious business, a signal moment in the gathering fight of human beings to do something about global warming before it’s too late to do anything but watch. You’ll tell your grandchildren, assuming we win. So circle September 20th and 21st on your calendar, and then I’ll explain.
