    I been doing some serious research, and have come to the conclusion that methane, not
    CO2, is the Earths real green house accelerating gas.

    Scientists have concluded, that methane, trapped under the Earths oceans, and frozen in Artic, and Antartic ice, is what has heated the Earth in the past, and will reheat the Earth
    in the Future.

    Garbage land fills are also another big producer of methane. So, while many people focus on CO2, methane is three times more effective at raising the Earths overall global temperature, than CO2 is.

    Maybe Monsignor Al Gore from the Church of the Hot and Gooey Death and Discount House of Carbon Credits will come along and make excuses....ah..I mean explain it.

    Cap & Tax for nothing.

    First, the CO2 is the primary GHG. Second, while methane, in the form of clathrate outgassing can provide the kick that puts us into a major climate change, it is CO2, with is formed as the CH4 oxidizes, that creates a long term heat effect.

    The whole effect is covered here;

    So you are capable of third grade humor. What else is new?

    I thought you knew I don't pay any attention to people who start a conversation with the phrases "CO2, Global Warming, or Fossil Fuels".

    Water vapor traps even more heat.

    Are over educated under-common-sensed globalist/socialist authoritarians going to try and regulate cumulus clouds now??

    O3 retains the most heat, maybe we need more aerosol cans to get rid of it!

    What the science says...
    Water vapour is indeed the most dominant greenhouse gas. Water vapour is also the dominant positive feedback in our climate system and amplifies any warming caused by changes in atmospheric CO2.


    Water vapour is indeed the most dominant greenhouse gas. The radiative forcing for water is around 75 W/m2 while carbon dioxide contributes 32 W/m2 (Kiehl 1997). Water vapour is also the dominant positive feedback in our climate system and a major reason why temperature is so sensitive to changes in CO2.

    Unlike external forcings such as CO2 which can be added to the atmosphere, the level of water vapour in the atmosphere is a function of temperature. Water vapour is brought into the atmosphere via evaporation - the rate depends on the ocean and air temperature and is governed by the Clausius-Clapeyron relation.

    If extra water is added to the atmosphere, it condenses and falls as rain or snow within a week or two. Similarly, if somehow moisture was sucked out of the atmosphere, evaporation would restore water vapour levels to 'normal levels' in short time.

    Water Vapour as a positive feedback
    As water vapour is directly related to temperature, it's also a positive feedback - in fact, the largest positive feedback in the climate system (Soden 2005). As temperature rises, evaporation increases and more water vapour accumulates in the atmosphere. As a greenhouse gas, the water absorbs more heat, further warming the air and causing more evaporation.

    How does water vapour fit in with CO2 emissions? When CO2 is added to the atmosphere, as a greenhouse gas it has a warming effect. This causes more water to evaporate and warm the air more to a higher (more or less) stabilized level. So CO2 warming has an amplified effect, beyond a purely CO2 effect.

    How much does water vapour amplify CO2 warming? Without any feedbacks, a doubling of CO2 would warm the globe around 1°C. Taken on its own, water vapour feedback roughly doubles the amount of CO2 warming. When other feedbacks are included (eg - loss of albedo due to melting ice), the total warming from a doubling of CO2 is around 3°C (Held 2000).

    Water vapor is the most powerful greenhouse gas

    Dude, you are just as willfully ignorant as ever.
