Wrong monkey brains.
Water vapor is by far the dominant greenhouse gas. And, thank God becasuse with out it we would still be Snowball Earth.
Here's another inconvenient truth for you monkey brains. Man hasn't released that much CO2. Some day you really need to get a clue and quit posting all your bull shit.
Although water vapor has a greater greenhouse effect, CO2 is the more important greenhouse gas for long term climate changes and global warming. Water vapor is self limiting and does not accumulate like CO2 .
"So why aren't climate scientists a lot more worried about water vapour than about CO2? The answer has to do with how long greenhouse gases persist in the atmosphere. For water, the average is just a few days.
This rapid turnover means that even if human activity was directly adding or removing significant amounts of water vapour (it isn't), there would be no slow build-up of water vapour as is happening with CO2 (see Climate myths: Human CO2 emissions are tiny compared with natural sources).
The level of water vapour in the atmosphere is determined mainly by temperature, and any excess is rapidly lost. The level of CO2 is determined by the balance between sources and sinks, and it would take hundreds of years for it to return to pre-industrials levels even if all emissions ceased tomorrow. Put another way, there is no limit to how much rain can fall, but there is a limit to how much extra CO2 the oceans and other sinks can soak up."

Regardless, the fact that CO2 is responsible for twenty percent of immediate greenhouse effect means that when it goes up 35% from man as has been proven the GE is going to go up around 7%. But that is amplified by higher temps causing more vapor and clouds.
Why is this simple common sense thing so difficult for Republicans?
