A runaway greenhouse effect occurs when greenhouse gases accumulate in the atmosphere through a positive feedback cycle to such an extent that they substantially block radiated heat from escaping into space, thus greatly increasing the temperature of the planet.
Eventually, Venus became a runaway greenhouse with all the water dumped into the atmosphere trapping as much heat as possible, with the surface temperatures continuing to skyrocket.
The runaway greenhouse effect occurs if this feedback continues unchecked until all the water has left the surface and enters the atmosphere. For Mars and the Earth the runaway greenhouse was halted when water vapor became saturated with respect to ice or liquid water respectively.
Scientists investigate whether continued warming on Earth could cause a super greenhouse effect in tropical regions to “run away” as it might have on Venus.
Researchers have for the first time simulated all stages of a runaway greenhouse effect, finding that it could turn our green planet into uninhabitable "hell" in coming centuries, they said on Monday.
All that water vapor, itself a potent greenhouse gas, will raise temperatures higher still to cook another greenhouse gas, carbon dioxide, out of Earth’s rocks. The end result will be a “...
Planetary geologists think there is good evidence that Venus was the victim of a runaway greenhouse effect which turned the planet into the boiling hell we see today. A similar catastrophe is...
Our model is specifically developed to quantify the climate response of Earth-like planets to increased insolation in hot and extremely moist atmospheres. In contrast with previous studies, we find...
Researchers recently completed the first full simulation of a runaway greenhouse effect. When a planet like Earth heats up, the atmosphere collects more and more water vapor until the planet can...
Avoiding a runaway greenhouse on Earth requires that the atmosphere is subsaturated with water, and that the albedo effect of clouds exceeds their greenhouse effect. A runaway...
