Alternative Earths Ph.D student Marcus Bray and Co-Investigator Jennifer Glass (Georgia Tech) co-authored a new paper in 'Geobiology'. The research team examined methane production by microbes in the absence of marine 'iron-curtains'. Methane that escaped to the atmosphere may have played a prominent role in early-Earth greenhouse warming, despite a younger sun at the time.
