Could we cure climate change? Geoengineering researcher Tim Kruger wants to try. He shares one promising possibility: using natural gas to generate electricity in a way that takes carbon dioxide out of the air. Learn more -- both the potential and the risks -- about this controversial field that seeks creative, deliberate and large-scale intervention to stop the already catastrophic consequences of our warming planet.

Can we stop climate change by removing CO2 from the air?

Solving climate change requires more than slashing emissions; it demands removing trillions of tons of carbon dioxide from the atmosphere. One innovative approach uses natural gas to generate electricity while actually drawing CO2 out of the air, achieving a carbon-negative result of minus 600 grams per kilowatt-hour. Scaling these solutions will take defense-level spending, careful risk assessment, and global cooperation. This challenge is massive, but essential if future generations are to inherit a stable, healthy planet.
