greenhouse effect
Energy radiated by the sun converts to heat when it reaches the earth. Some heat is reflected back through the atmosphere, while some is absorbed by atmospheric gases and radiated back to the earth.

greenhouse effect

n.
A phenomenon in which the atmosphere of a planet traps radiation emitted by its sun, caused by gases such as carbon dioxide, water vapor, and methane that allow incoming sunlight to pass through but retain heat radiated back from the planet's surface.

greenhouse effect

n
1. (General Physics) an effect occurring in greenhouses, etc, in which radiant heat from the sun passes through the glass warming the contents, the radiant heat from inside being trapped by the glass
2. (Physical Geography) the application of this effect to a planet's atmosphere; carbon dioxide and some other gases in the planet's atmosphere can absorb the infrared radiation emitted by the planet's surface as a result of exposure to solar radiation, thus increasing the mean temperature of the planet

green′house effect`


n.
heating of the atmosphere resulting from the absorption by certain gases of solar energy that has been captured and reradiated by the earth's surface.

green·house effect

(grēn′hous′)
The trapping of the sun's radiation in the Earth's atmosphere due to the presence of greenhouse gases.

greenhouse effect

1. The term given to the heating of the Earth’s surface caused by infrared radiation trapped in the atmosphere.
2. Alleged human-made atmospheric warming by accumulating gases trapping solar heat below them rather like a greenhouse roof. See greenhouse gases.

However, all of them occupy what scientists call the Venus zone, a range of stellar distances where a planet with an initial Earth-like atmosphere could experience a runaway greenhouse effect that transforms it into a Venus-like atmosphere.
Once collisions stopped, CO2 again built up from volcanic eruptions and a runaway greenhouse effect warmed the planet.
This is true about climate: If we can grasp the mechanism and timing of the runaway greenhouse that destroyed Venus's surface oceans, we'll know better what lies ahead for our world when the Sun inevitably warms it to the point that Earth can no longer hold its water (S&T: Oct.
"Climate scientists" often throw around terms such as C[O.sub.2] forcing, sensitivity, positive feedback loop, tipping point, and runaway greenhouse when attempting to explain the supposedly disastrous effects of C[O.sub.2] on our planet.
The second planet from the sun, Venus, was once actually a lot like Earth (https://www.nasa.gov/feature/goddard/2016/nasa-climate-modeling-suggests-venus-may-have-been-habitable) until a runaway greenhouse effect dried up all the oceans and left the planet hot and dry.
On Venus, for example, a positive feedback is thought to have evolved into a runaway greenhouse effect.
In the late 60s, sending aprobe to Venus was accomplished by the common, tried-and-test method of: combination of high surface temperatures, large atmospheric pressures, harsh chemical compositions - a result of the runaway greenhouse effect on Venus - as well as showers of sulphuric acid rain.
Will Earth be like Venus which has a runaway greenhouse CO2 and temperature all around at 470 Celsius?
The finding suggests how Earth might once have rapidly reversed a runaway greenhouse effect.

He asks, " [Could a runaway greenhouse effect] that once happened on Venus also happen here on Earth?
