... the constant flow of images undercuts the sense that there's actually something wrong with the world. How can there really be a shortage of whooping cranes when you've seen a thousand images of them - seen ten times more images than there are actually whooping cranes left in the wild?

Winning slowly is another way of losing. Americans are screwing up our health care system again right now. That's going to cause grave trouble for people over the next five, 10 years. There are going to be lots of people who die, lots of people who are sick. It's going to be horrible. But 10 years from now it will not be harder to solve the problem because you ignored it for those 10 years. With climate change, that's not true. As each year passes, we move past certain physical tipping points that make it impossible to recover large parts of the world that we have known.

A price on carbon sufficient to keep 80% of current reserves underground, rebated directly to citizens.

I also think we need unconventional political action, and I increasingly think that there is a need for people of faith to be able to do the kind of things that people of faith did 40 years ago in the heat of the civil rights revolution. This is a moral issue of every bit as much importance requiring every bit as much sacrifice, courage, and energy as that crisis did.

The models that have been constructed agree that when, as has been predicted, the level of carbon dioxide or its equivalent in other greenhouse gases doubles from pre-Industrial Revolution concentrations, the global average temperature will increase, and that the increase will be 1.5 to 4.5 degrees Celsius or 3 to 8 degrees Fahrenheit... In Dallas, for instance, a doubled level of carbon dioxide and other gases like methane, would increase the number of days a year with temperatures above 100 degrees from 19 to 78 each year.

Everybody was cratered after Copenhagen. If the movie had worked the way that it should have, if it had been scripted by Holywood, the world would have come together and addressed the biggest problem it ever had faced and delegates would have embraced each other, and it all would have been a good happy scene instead of the complete farce and debacle that it turned into - maybe in certain ways, an absolute low point for human diplomacy.

Policies that engage us again in the international fight for real climate protection.
