The most blatant examples are increased power and frequency in hurricanes and the increased depth and frequency of heat waves.

When you go to China and the developing world, people understand more clearly the dangers that are coming at them because they're living closer to the margin. They don't have any of the false sense of invulnerability that Americans have. People from developing countries also feel that it's their right, if you're talking in terms of justice, to use fossil fuels like we did for a hundred years to get rich. It's hard for them to give up that vision.

I can't tell how moving it is to open my email and see a picture of 1,500 Buddhist monks and nuns in the Himalayan kingdom of Ladakh forming a human 350 against the backdrop of the melting glaciers. This is not their fault, and yet they're stepping up to be part of the solution.

We can either save the planet from catastrophic warming, or protect fossil fuel CEOs. Not both. Do the math(s)

Other thing we need to understand is that the financial power of the fossil fuel industry has so far prevented even any minor progress. They have a sweetheart deal unlike any other business on Earth: they're allowed to dispose of their waste for free, to use the atmosphere as an open sewer. And they will do all they can to defend that special privilege.

Sometimes, I, anyway, get tired of playing defence, and like to play offence.

what you do every day is what forms your mind and precious few of us can or would spend most days outdoors.
