The greenhouse effect on Earth is defined as: "The infrared radiative effect of all infrared absorbing constituents in the atmosphere.Greenhouse gases (GHGs), clouds, and some aerosols absorb terrestrial radiation emitted by the Earth’s surface and elsewhere in the atmosphere."
Though water plays a major role in the process, the runaway greenhouse effect is not a result of water vapor feedback. [4] The runaway greenhouse effect can be seen as a limit on a planet's outgoing longwave radiation that, when surpassed, results in a state where water cannot exist in its liquid form (hence, the oceans have all "boiled away").

This is an accepted version of this page This is the latest accepted revision, reviewed on 10 January 2025. Gas in an atmosphere with certain absorption characteristics This article is about the physical properties of greenhouse gases. For how human activities are adding to greenhouse gases, see Greenhouse gas emissions. Greenhouse gases trap some of the heat that results when sunlight heats ...
Earth constantly absorbs energy from sunlight and emits thermal radiation as infrared light. In the long run, Earth radiates the same amount of energy per second as it absorbs, because the amount of thermal radiation emitted depends upon temperature: If Earth absorbs more energy per second than it radiates, Earth heats up and the thermal radiation will increase, until balance is restored; if ...

Greenhouse gas (GHG) emissions from human activities intensify the greenhouse effect. This contributes to climate change . Carbon dioxide (CO 2 ), from burning fossil fuels such as coal , oil , and natural gas , is the main cause of climate change.
An increase in water vapor results in positive ΔE W due to further enhancement of the greenhouse effect. A slower positive feedback is the ice-albedo feedback . For example, the loss of Arctic ice due to rising temperatures makes the region less reflective, leading to greater absorption of energy and even faster ice melt rates, thus positive ...
A runaway greenhouse effect is a tipping point so extreme that oceans evaporate [182] and the water vapour escapes to space, an irreversible climate state that happened on Venus. [183] A runaway greenhouse effect has virtually no chance of being caused by people.
