Increased insolation threshold for runaway greenhouse processes on Earth like planets

open access: yes, 2013
Because the solar luminosity increases over geological timescales, Earth climate is expected to warm, increasing water evaporation which, in turn, enhances the atmospheric greenhouse effect.
