Atmospheric Composition and the Inner Edge of the Habitable Zone: Coupling 3D Climate Modeling with E. coli Experiments

To the point

Asena Kuzucan, Emeline Bolmont, Guillaume Chaverot, Jaqueline Quirino Ferreira, Bastiaan Willem Ibelings, Siddharth Bhatnagar, and Daniel Frank McGinnis from Geneva institutions show that coupling 3D climate modeling for H2- or CO2-dominated atmospheres with E. coli K-12 experiments reveals how atmospheric composition, not just distance from a star, shapes surface water and bacterial survival at the inner edge of the habitable zone, so habitability assessments must consider a variety of atmospheric environments.
