Take air. Suck out CO2. Make fuel. A lab advance hints at a future for artificial photosynthesis

Researchers believe that artificial photosynthesis that sucks excess CO2 out of the air could one day help fight climate change. But capturing the gas is only half the challenge. The other half is what to do with it once you've got it. Lauren Sommer reports on a potentially breakthrough technology that uses artificial photsynthesis to turn CO2 from the air into industrial chemicals and natural gas.

The Green New Deal doesn't include carbon pricing. Some say that's a big mistake.

The Green New Deal resolution recently introduced by Democrats in Congress calls for the US to quickly decarbonize its economy, but does not mention carbon pricing, a strategy supported by many economists. In a recent editorial, The Washington Post laid out its case for putting a high price on carbon to encourage decarbonization rather than imposing government mandates.
