When it comes to climate, we can all make a big difference.

If youre a young person looking at the future of this planet and looking at what is being done right now, and not done, I believe we have reached the stage where it is time for civil disobedience to prevent the construction of new coal plants that do not have carbon capture and sequestration.

Our world faces a true planetary emergency. I know the phrase sounds shrill, and I know it's a challenge to the moral imagination.

Is there some magic wand they can wave on it and presto! - physics is overturned and carbon dioxide doesn't trap heat anymore? And when we see all these things happening on the Earth itself, what in the hell do they think is causing it? The scientists have long held that the evidence in their considered word is "unequivocal," which has been endorsed by every national academy of science in every major country in the entire world.

There is the natural tendency that all of us are vulnerable to, to deny unpleasant realities and to look for any excuse to push them away and resolve to think about them another day long in the future.

Our planet has a rising fever. If the crib catches fire you don't say: 'Hmmm, how fast is that crib going to burn? Has it ever burned before? Is my baby flame retardant?'

As I have said for many years throughout this land, we're borrowing money from China to buy oil from the Persian Gulf to burn it in ways that destroy the future of human civilization. Every bit of that has to change.
