Episode 18: Searching for Methane, the Other Greenhouse Gas - with Robert Green of NASA’s Jet Propulsion Laboratory - a podcast by Miles OBrien: Science, Technology & Aerospace Journalist

Robert Green is a world-renowned expert in spectroscopy, which is a great way to find methane on distant planets, but also ours, as I learned in this interview.
