Though there are still hurdles to leap, states basically know how to eliminate emissions from the electrical grid, said Mike O’Boyle, head of electricity policy at the think tank Energy Innovation in San Francisco.

For people feeling that they have fallen from grace, who yearn to return to a time without fossil fuels, the idea of regenerative agriculture could hold real power.

In a grand experiment, California switched on a fleet of high-tech greenhouse gas removal machines last month. Funded by the state’s cap-and-trade program, they’re designed to reverse climate change by sucking carbon dioxide out of the atmosphere. These wonderfully complex machines are more high-tech than anything humans have designed. They’re called plants.

This appears to be the core of the oil companies’ strategy. First, believe everything the IPCC says. Second, the IPCC says the real problem is prosperity, economic growth! Therefore, blame the ones burning the oil — all we did was dig the stuff up.

The city of Pueblo wants to go all-in on renewables. Low-income residents want affordable rates. Can they work together? The first things you see driving down from the Rocky Mountains into Pueblo, Colorado, are smoke stacks. Three big ones sprout from the Comanche coal plant at the edge of town, and then a stubble of shorter towers rises from the steel mill, which once provided good paying jobs to anyone who wanted one.

For years, environmental justice advocates have been saying that it’s time to shift the focus of the environmental movement from beautiful landscapes and big animals to the people choking on black carbon or poisoned by lead in their water. Now, some of those people who grew up in dumping grounds have come into power and are shaping politics on the world stage. And when California sent a delegation to the U.N. climate conference in Bonn a few weeks ago, it was packed with members of the movement, including state Senator Ricardo Lara.
