Closing the Carbon Cycle

One way to get to negative CO2 emissions is to capture CO2 from the ambient air. Peter Eisenberger and colleagues are developing ways to mimic nature by using CO2 to make synthetic liquid fuels that are carbon neutral.

Waves Lapping at Your Door

To understand how the ice sheets will respond to global warming and how sea level could rise, we need to know what happened to sea level the last time CO2 levels were this high.
