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.

In a free society, there comes a time when the truth - however hard it may be to hear, however impolitic it may seem to say - must be told.

The center of the earth is about a million degrees.

If we walk down the sidewalk of any street in America a significant number of the people we pass by, if we dug into what they're going through in their lives, they're carrying burdens that they don't talk about but they're extremely heavy and painful. And so, one of the secrets of the human condition is that suffering binds people together. And when you go through something agonizing, others who know what you're feeling because they've been through it will so often reach out to you and connect with you, and give you strength and lift you up.

The truth about the climate crisis is still inconvenient to the large carbon polluters. And so they want to bob and weave and dodge the truth, and pretend like it's still a big controversy, and it's not. They want to pretend that this is up for debate. Like, whether or not the world is round is up for debate, or whether the moon landing really took place.

When you have the facts on your side, argue the facts. When you have the law on your side, argue the law. When you have neither, holler.
