Sucking CO2 out of the air using synthetic leaves

What about all the carbon we've already poured into the atmosphere? If only there were a device that could take some of it back out.

Researchers at Arizona State University’s Center for Negative Carbon Emissions are working on one. They discovered a commercially available resin that can grab carbon dioxide at low concentrations when the material is dry and release it when the material is moist. The CO2 it collects could be stored underground, used in greenhouses, or fed to algae for biofuel production.

"Right now, we are taking carbon out of the ground. We then convert the energy into something useful. Then there’s a third step that we ignore—namely, to clean up after ourselves," said Klaus Lackner, the center’s director.
