    By now, we all know that CO2 is a deadly poisonous, toxic gas; even a de minimus increase in this trace element can wipe out all life on Earth, except of course for Al Gore and a few cockroaches.

    This gas is so deadly the Obama Administration is thinking of banning exhaling in order to combat ManMade Climate Change Global WarmerCoolering Global CoolerWarmering the Great Climactic Googly Moogly!!

    But we also learned that H2O is a more powerful Greenhouse Gas than CO2 yet we never ever never ever never ever hear how much H2O was in the atmosphere 50 or 100 years ago.

    This can only mean, as usual, Libruls are totally full of methane.

    Amiright?

    A complete demonstration of one braindead fool.

    Water vapor is indeed a powerful greenhouse gas, but there is plenty of room for CO2 to play a role | How to Talk to a Climate Skeptic: Responses to the most common skeptical arguments on global warming | Grist

    (Part of the How to Talk to a Global Warming Skeptic guide)

    Objection: H2O accounts for 95% of the greenhouse effect; CO2 is insignificant.

    Answer: According to the scientific literature and climate experts, CO2 contributes anywhere from 9% to 30% to the overall greenhouse effect. The 95% number does not appear to come from any scientific source, though it gets tossed around a lot.

    Please see this paper (PDF), the textbook referenced here, and this article at RealClimate.

    There is a very important distinction to be made, as you will read if you follow the link to Real Climate, between water vapour's role in the Earth's Greenhouse effect and it's role in climate change. If you were to read through the table of climate forcings in the IPCC report or at NASA's page about forcings in its GCM, you won't find water vapour there at all. This is not because climate scientists are trying to hide the role of water vapour, rather it is because H2O in the troposphere is a feedback effect, it is not a forcing agent. Simply put, any artificial perturbation in water vapour concentrations is too short lived to change the climate. Too much in the air will quickly rain out, not enough and the abundant ocean surface will provide the difference via evaporation. But once the air is warmed by other means, H2O concentrations will rise and stay high, thus providing the feedback.

    See what happens when you ask a simple question about the Great Climatic Googly Moogly?

    You get "Don't look behind the curtain!"

    Basically, the response is, "H2O is a more powerful greenhouse gas, but we're ignoring it because you can control the economy via CO2 emissions but we can't destroy Western Civilization by asking people to stop taking hot showers."

    Oh, and douchebag Old Rock neg repped me even daring to ask the question.

    You see the height of douchebaggery one has to contend with on the topic of ManMade GlobalWarmerCoolering?

    Oh, there's an article from "Real Climate" that's comforting. I mean Climatology is a settled science unlike that hit or miss science called physics.

    Frank, you are an ignorant ass for sure. Here is a site from the American Institute of Physics.

    The Carbon Dioxide Greenhouse Effect

    By the way, if you wish this continued exchange of ridicuous insults, I can do that. If you wish to debate the subject with real information, like adults, I can do that also.

    Debating Climatology is like debating shapes in clouds; there's no real science behind it especially when it comes to de minimus changes in the atmosphere trace element CO2.

    "CO2 contributes anywhere from 9% to 30% to the overall greenhouse effect."

    How are you supposed to take this seriously? HOW?

    "Great googly moogly," made popular by Frank Zappa in the song "Nanook Rubs It" from Apostrophe in 1974.

    Or...
