The runaway greenhouse effect on Venus occurred when carbon dioxide (CO2) levels got so high that it caused an extreme temperature rise. Venus used to have oceans, but these have all boiled dry.
VENUS
EarthVenusMarsThe greenhouse effect occurs on every planet with an atmosphere (including Earth). On Venus, there is a runaway greenhouse effect causing temperatures high enough to melt lead.Mars has a greenhouse effect that is weak because of its thin atmosphere.
Venus. The atmosphere of Venus consists of about 96.5% carbon dioxide (CO2), a powerful greenhouse gas.
Yes.(Another contributor writes:)It has a very thick atmosphere of Carbon dioxide that is thought to be a runaway greenhouse effect. Its average surface pressure due to the thick atmosphere is 93 bar, or 93 times that of Earth's. It is also the hottest planet, with surface temperatures averaging around 460°C (860°F).Yes it does, so hot that it has boiled its oceans dry.
NO.
Venus has the most pronounced greenhouse effect in our solar system. Its thick atmosphere is composed mostly of carbon dioxide, which traps heat and creates a runaway greenhouse effect, resulting in extreme temperatures of up to 900°F (475°C) on the surface.
The answer that you are looking for is "Venus". That planet has a dense atmosphere of CO2, which has produced a runaway greenhouse effect. When the Earth ocean evaporate, as in this scenario, all of the dissolved CO2 will be liberated and end up in the atmosphere as well, giving us a Venus like greenhouse.
The greenhouse effect is happening on any planet with greenhouse gas. Mars, as an example has greenhouse gases in it's atmosphere and has seen warming over the past hundred years similar to our warming trend. Venus, with an atmosphere of 96.5% carbon dioxide, has a runaway greenhouse effect which has caused the oceans to boil dry.
Two other planets besides Earth.Venus has a runaway greenhouse effect, with most of its atmosphere carbon dioxide, and a temperature of 460° Celsius.Mars has a very faint greenhouse effect, with a little carbon dioxide, but hardly any atmosphere at all.Saturn's largest moon, Titan, has a greenhouse effect, with large concentrations of methane.
A runaway greenhouse effect caused by Venus's thick atmosphere composed mainly of carbon dioxide and other greenhouse gasses.
Venus has a runaway greenhouse effect that has boiled its oceans dry.
Venus has the hottest greenhouse effect, a runaway effect, with an average surface temperature of 735 K (462 °C; 863 °F), Venus' atmosphere is 96.5% carbon dioxide.
