How has the greenhouse effect altered Venus?
It's made Venus a lot hotter, of course.
How might the fact that Venus has very high levels of carbon dioxide influence the greenhouse effect on that planet?
A runaway greenhouse effect has not been clearly defined. There was a runaway greenhouse effect on Venus, where positive feedback increased its greenhouse effect till the oceans boiled dry. A runaway greenhouse effect like that would mean the end of all life on the planet. The InterGovernmental Panel on Climate Change (IPCC) hardly mentions it. One of the few times it does, it says, in Session 31, "a runaway greenhouse effect" - analogous to Venus…
The atmosphere of Venus has a very high level of carbon dioxide How might this affect the greenhouse effect on Venus?
Which planet's poisonous atmosphere has been described as the product of a runaway greenhouse effect?
Venus, the second planet from the sun, is covered in clouds and has a very high surface temperature due to its greenhouse effect. Due to an excess amount of carbon dioxide (CO2), its temperature is 460 degrees Celsius or 850 Fahrenheit or 735 Kelvin. It is the hottest planet. It has a very thick atmosphere of Carbon dioxide that is considered a runaway greenhouse effect. Its average surface pressure due to the thick atmosphere is…
