Venus is like 1000 degrees ( too lazy to look up the real temp :p) solely because of the amount of CO2 in the atmosphere. Your right we already get to pay the price. But how bad it gets is still up to us.
The first problem is that the surface of Venus receives no direct sunshine. The Venusian atmosphere is full of dense, high clouds “30–40 km thick with bases at 30–35 km altitude.” The way a greenhouse effect works is by shortwave radiation warming the ground, and greenhouse gases impeding the return of long wave radiation to space. Since there is very little sunshine reaching below 30km on Venus, it does not warm the surface much. This is further evidenced by the fact that there is almost no difference in temperature on Venus between day and night. It is just as hot during their very long (1400 hours) nights, so the 485C temperatures can not be due to solar heating and a resultant greenhouse effect. The days on Venus are dim and the nights are pitch black.
The next problem is that the albedo of Venus is very high, due to the 100% cloud cover. At least 65% of the sunshine received by Venus is immediately reflected back into space. Even the upper atmosphere doesn’t receive a lot of sunshine. The top of Venus’ atmosphere receives 1.9 times as much solar radiation as earth, but the albedo is more than double earth’s – so the net effect is that Venus’ upper atmosphere receives a lower TSI than earth.
The third problem is that Venus has almost no water vapor in the atmosphere. The concentration of water vapor is about one thousand times greater on earth.

The volcanic activity could account for the lack of ground sunlight. The co2 could be trapping the volcanic heat the same way earth traps the suns heat.

Hehehe this from the guy saying 90% of the worlds actual real scientists are either wrong or in a big conspiracy to confuse him.
You really are cute. :p

But 90% of them agree with the evidence and validity of there colleagues.

Well since they all can't see the bigger picture because of the compartmentalization but you can. Thank god your so insightful compared to the people actually working in that field.

I gotta disagree..... Do you know how ridiculous the thought that all of science is in on a conspiracy? That would require every science major coming out of college to turn down money and fame just to keep the hoax going.
