[QUOTE="taykair, post: 169913, member: 9418"] It is generally believed that Venus' current state is due to a runaway greenhouse effect. Because of Venus' nearness to the Sun (compared with Earth), carbon dioxide never got absorbed due to the higher temperature. Carbon dioxide is a greenhouse gas and traps heat, so this would lead to even higher temperatures, which would lead to even more carbon dioxide released from the surface rocks, and so on and so on. Venus' atmosphere is now about 97% carbon dioxide. Most scientists believe that, at one point, there were oceans of liquid carbon dioxide on its surface, which would account for its present, thick carbon dioxide atmosphere. However, I have a different theory: The remaining 3% of the Venusian atmosphere is mostly nitrogen. I believe that, long ago, this percentage was much higher. I think that, instead of carbon dioxide oceans, there was instead an abundance of vegetation (requiring higher levels of nitrogen) which absorbed oxygen and released carbon dioxide. Whether there were more advanced life forms, I have no idea. By the way, I am not a scientist, so all of the above may be total BS. [/QUOTE]
