Substantial extension of the lifetime of the terrestrial biosphere

R. J. Graham, Itay Halevy, Dorian Abbot

Approximately one billion years (Gyr) in the future, as the Sun brightens, Earth's carbonate-silicate cycle is expected to drive CO $_{2}$ below the minimum level required by vascular…

Resilience of Snowball Earth to Stochastic Events

Guillaume Chaverot, Andrea Zorzi, Xuesong Ding +6

Earth went through at least two periods of global glaciation (i.e., ``Snowball Earth'' states) during the Neoproterozoic, the shortest of which (the Marinoan) may not have lasted s…

Carbon cycle instability for high- $C O_{2}$ exoplanets: Implications for habitability

R. J. Graham, R. T. Pierrehumbert

Implicit in the definition of the classical circumstellar habitable zone (HZ) is the hypothesis that the carbonate-silicate cycle can maintain clement climates on exoplanets with l…
