Peter Ward says that the most important word is methane…and how it will change the world. He suggests a few ways diversity on Earth will come to an end: Accidentally: comet/asteroid, supernova, mass extinction (e.g., greenhouse), human-caused (runaway non, nuclear war).

It’s an amusing, huge-focus presentation on the arc of life. We are, he says, on our way back to becoming Planet Yogurt: bacterial life will continue until the Sun pulses and explodes.

Shorter term, he thinks we’re heading for an ice age.

He says the next presidential election is the most important in history because we’re facing climate changes that we can forestall and that would be cataclysmic.
