..."Greenhouse Effect" ?
We seem to be having a fairly decent debate here. I like that about YA. It is more difficult to silence the opposition here than it would be say in an interview with Olbermann.
 
Water vapor is the green house effect. Co2 is cheap natural plant food and has such a marginal effect on the greenhouse effect most real scientists do not even include it.

The real problem is that those who promote the AGW agenda know very little about science and how things really work. The sun is the source of 98% of the energy that warms the earth.

One of the reasons they do not understand the lags between climate shifts after the sun increases or decreases its output is they flat do not comprehend thermal inertia.

Lots of water vapor answers here. Water vapor takes up a much larger percentage of the atmosphere than carbon dioxide does. For that reason, water vapor has more of an impact.
However, nitrous oxide in the atmosphere has almost 300 times the effect than carbon dioxide does. Growing rapeseed gives off nitrous oxide. Larger areas of rapeseed were planted last year to make more biodiesel.

Of the three gases I just mentioned, water vapor makes up 0-4% of the atmosphere, carbon dioxide 0.036%, and nitrous oxide 0.00003%. Human activity makes up a very small percentage of that 0.036% and 0.00003%, yet the government and environmentalists continue to tell the world these emissions must be reduced.

WeatherRusty says solar variations are small. Scientists who claim solar activity has no impact on Earth's weather do not mention that Mars' polar caps shrunk the same time the Earth's temperature was higher. Neptune also was warmer from 1980-2004. (By the way, there are numerous articles in Astronomy magazine throughout the 1980's that mention the growing and shrinkage of Both of Mars' polar caps.)
 
Rohit co2 is a trace gas, 380 ppm that's parts per million that means if you have a stack of 1,000,000 $1.00 bills, 380 would represent the co2. the other 999,620 would be the rest of the atmosphere of which water vapor isn't included because it isn't a gas, but it is 95% of the greenhouse of earth.
 
Water vapor. The alarmists' pet CO2 makes up 0.036% of greenhouse gasses, and about 0.00003% is man-made. If you were to say to an alarmist that whatever plans they may come up with will increase unemployment by 30%, then they'll say that it's a small, insignificant amount; but apparently 0.00003% is a massive, apocalyptic percentage.
 
Water vapor is the principle greenhouse gas responsible for the greenhouse effect. The mixing ratio or concentration of water vapor varies greatly from place to place and thus does the strength of the greenhouse effect. Warm tropical rain forests remain warm at night, while dry deserts heat up greatly during the day and cool a great deal at night. The difference is due to the moisture content of the air.

Your question does not address the issue of global warming however. The water vapor content of the air is dependent on the source of the air mass, whether it has passed over a long stretch of water or dry land. It is also dependent on altitude, moisture decreases rapidly with increasing altitude. Most importantly, the saturation vapor pressure for water vapor increases exponentially with increasing temperature. A little warming allows for much more water vapor to reside in the air so anything that warms the air will have the effect of increasing the water vapor content and thus the greenhouse effect.

Variations in the Sun's output will warm and cool the Earth and thus modulate the impact of the greenhouse effect. Variations in the Sun's output are very small however, measured to be about 1.3 Watt/meter^2 over the range of the 11 year sunspot cycle.
A doubling of CO2 will produce 3.7W/meter^2 sustained and 1.2C of warming by itself before considering water vapor feedback.

But we know there will be a positive water vapor feedback as mentioned above which will approximately double the forcing given by CO2 alone giving about 8W/meter^2. Oceans warm, glaciers melt, ice caps shrink, albedo decreases, sea levels rise....you know the rest of the story!
 
Water Vapor-----------Even Al Gore was forced to admit during a recent speech in Australia that his CO2 estimates were wrong and "possibly" over stated. AL is now blaming "carbon soot" as the culprit .
