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.
Only Venus and Earth have a greenhouse effect because they have a substantial atmosphere. Venus actually has a runaway greenhouse effect causing its surface temperatures to rise to 450 Celsius.
Venus. The atmosphere of Venus consists of about 96.5% carbon dioxide (CO2), a powerful greenhouse gas.
NO.
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.
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.
Venus. Similar to Earth in many ways, a runaway greenhouse effect is thought responsible for its 900°F (480°C) surface temperature.
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.
