Runaway greenhouse planet
 List and explain the three major factors that control the...)
A runaway version of the greenhouse effect can be defined by a limit on a planet's outgoing longwave radiation which is asymptotically reached due to higher surface temperatures evaporating a condensable species (often water vapor) into the atmosphere, increasing its optical depth. [2] 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 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 … Visa mer 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 … Visa mer Venus A runaway greenhouse effect involving carbon dioxide and water vapor may have occurred on Visa mer • Steffen, Will; Rockström, Johan; Richardson, Katherine; Lenton, Timothy M.; Folke, Carl; Liverman, Diana; Summerhayes, Colin … Visa mer Webb14 dec. 2013 · Thus, our home planet may be subject to a moist greenhouse climate in a mere ~170 million years [Gough, 1981].
