Tracking methane from space to slow the warming of Earth
Podcast: Marketplace TechPublished On: Fri Aug 25 2023
Description: This year could become the hottest one ever recorded. In reporting on the climate crisis, carbon dioxide gets most of the headlines. But molecule for molecule, methane is a far more potent greenhouse gas. It’s odorless and colorless, making it difficult to detect. While CO2 can linger in the atmosphere for centuries, methane lasts more like seven to 12 years. And because methane is so potent, the ability to quickly detect and fix leaks could have an immediate climate benefit. The nonprofit Carbon Mapper tracks greenhouse gas emissions by flying planes with imaging spectrometers over oil and natural gas hubs and other spots where leaks can cluster. But to scale things up, it’s working with NASA’s Jet Propulsion Laboratory on an instrument that can detect methane releases from space. Marketplace’s Lily Jamali recently spoke about the mission and its mechanics with JPL senior research scientist Rob Green at the lab’s campus in Pasadena, California, outside the “clean room” where the instrument has been developed.
