<div class='quotetop'>QUOTE (Denny Crane @ Jun 24 2008, 05:17 PM) <{POST_SNAPBACK}></div><div class='quotemain'>Another interesting tidbit:
http://en.wikipedia.org/wiki/Mars
The atmosphere on Mars consists of 95% carbon dioxide, 3% nitrogen, 1.6% argon, and contains traces of oxygen and water.
(Yet it's a lot colder than Earth, Mercury, or Venus)</div>
Distance from the Sun (where Earths distance from the Sun is 1 AU)
Mercury 0.39 AU
Venus 0.72 AU
Earth 1 AU
Mars 1.52 AU
One thing to note is that Mars does not have a strong atmosphere, so the C02 does have a greenhouse effect, but not nearly as much as a planet that has a denser atmosphere composed primarily of C02 like Venus does.
Mars Pressure at surface 0.8 KPa.
Earth Pressure at surface 101.3 KPa (100 times more than Mars)
Venus Pressure at surface 9.1 MPa (100 times more than Earths)
Anyway, Mars doesn`t get nearly as cold as Mercury does despite being roughly 4 times further away from the Sun. Mercury reaches -180 degrees celcius, while Mars reaches -80 degrees celcius. The C02 traps some of the heat in as a greenhouse gas. Otherwise Mars would reach colder temperatures than Mercury would at such a great distance.

Oh and regarding the volcanoes on Venus. Why would you even bring this up?

The temperature of Venus despite being further away from the Sun than Mercury and staying warmer is due to the C02 not extinct Volcanoes that have no impact on the temperature today. Anyway a Volcano would not explain the difference that we see in temperature between Mercury and Venus even if they were active everyday.

I feel strongly about limiting how much we damage the environment, but the man is f'n right. No matter how hard people try to spin it as a selfless act, this environmental awareness and concern is motivated purely out of self-interest. None of us want to be stuck in a polluted environment or have to deal with the Earth's reaction to us.</div>
Agreed
Or for some people it's about making a name for themselves like Al Gore. But yea, for sure people are selfish when they are thinking about this stuff. I had a professor who said that he worked for Esso and Esso was drilling for Oil in I think Peru and Esso said this will be expensive because we have to remove the waste and clean the stuff, because it would affect the drinking water and the environment, but the Peruvians didnt care about it, because the river flows into Equador. (another country who they dislike lol)
