We must quickly mobilize our civilization with the urgency and resolve that has previously been seen only when nations mobilized for war. These prior struggles for survival were won when leaders found words at the 11th hour that released a mighty surge of courage, hope and readiness to sacrifice for a protracted and mortal challenge.

I would distinguish between Donald Trump and the United States of America. Although he is president, he does not speak for the country on the climate change, and that was vividly illustrated in the aftermath of his speech pulling the US out of the Paris Agreement. Almost immediately, not only did the rest of the world double down on its commitments, but also here in this country, governors, mayors, business leaders, they said, we're still in the Paris Agreement, and they're doubling down. A lot of cities have now made a decision to go 100% renewable energy.

We can't negotiate the facts. We can't negotiate the truth about the situation. And for those who are too fearful to finish, it can be done and must be done. Make sure we succeed, . . . It is wrong for this generation to destroy the habitability of our planet and ruin the prospects of every future generation.

The truth is that we're at a critical juncture in the history of our species and if we don't act soon, we could inhabit a world we don't recognize anymore.

I would kiss Tipper much longer.

It's not unusual to find big political shifts that take place beneath the surface before they're visible above the surface.

I am Al Gore, and I used to be the next president of the United States of America.
