The runaway greenhouse effect is often formulated in terms of how the surface temperature of a planet changes with differing amounts of received starlight. If the planet is assumed to be in radiative equilibrium, then the runaway greenhouse state is calculated as the equilibrium state at which water cannot exist in … Visa mer A runaway greenhouse effect occurs when a planet's atmosphere contains greenhouse gas in an amount sufficient to block thermal radiation from leaving the planet, preventing the planet from cooling and from having … Visa mer The concept of a habitable zone has been used by planetary scientists and astrobiologists to define an orbital region around a star in … Visa mer • Climate change portal • Atmosphere of Venus, an example of a runaway greenhouse effect • Greenhouse and icehouse Earth • TRAPPIST-1b Visa mer While the term was coined by Caltech scientist Andrew Ingersoll in a paper that described a model of the atmosphere of Venus, the initial idea of a limit on terrestrial outgoing infrared radiation was published by George Simpson in 1927.

When stellar illumination equivalent to that received by Earth from the Sun is added, then the runaway greenhouse holds for about 500 Myr. root of context
