From: The future lifespan of Earth’s oxygenated atmosphere

Extended Data Fig. 1

a, The temperature dependence of terrestrial primary production (VT)48. b, The CO2 dependence of terrestrial primary production (VCO2). c, The UV irradiance dependence of terrestrial primary production (in terms of atmospheric O2) for different assumed values of cUV between 10−2.5 and 10−1.5 (fUV). d, The temperature dependence of marine primary producers (fTocn)24. The grey area represents the ranges for these factors that are explored by the stochastic approach.
