TV, and the culture it anchors, masks and drowns out the subtle and vital information contact with the real world once provided. There are lessons, enormous lessons, lessons that may be crucial to the planet's persistence as a green and diverse place and also to the happiness of it's inhabitants-that nature teaches and TV can't.

That's when the vast consensus of the world's climatologists, brought together by the UN and The Intergovernmental Panel on Climate Change, really announced that this was going on, and since then the accumulation of data and wickedly hot years has served to only congeal that consensus much more firmly.

The fight around climate change, which I've spent my life on, is somewhat more difficult than gay marriages because no one makes trillions of dollars a year being a bigot, and that's how much the fossil-fuel industry pulls in pumping carbon into the air. But the principle is the same, I think.

There hadn't really been a climate movement, per se. I think everyone spent twenty years thinking that if we just keep pointing out that the world is on the edge of the greatest crisis by far it's ever come to, then our leaders will do something about it. And it turned out that was wrong. They weren't going to do anything about it.

Certainly, packets of sea ice, in say the Arctic, which have failed to fully reform in the last couple of years.

Alone among businesses, the fossil-fuel industry is allowed to dump its main waste, carbon dioxide, for free.

Where people aren't as deeply reliant on fossil fuel as in the United States, it's far easier for them to imagine change on this scale. When you go to Europe, they're much more ready. They use half the amount of energy per capita that we use. They can imagine using less than that. They see the benefits. They're ready to go.
