    It seems that some places in North america have had record snow falls .

    Water vapor's effects derive from CO2's warming.

    Short of truly major disaster - the Venus heat trap - water vapor will not maintain itself in the atmosphere, or even self-accelerate its own accumulation. Left to itself It will precipitate out faster than it evaporates itself in, and take its greenhouse effects with it. Snowball earth was a consequence of global temperatures depending on water vapor, given a shortage of CO2.

    Methane is probably closer to self-accelerating feedback than water vapor = the methane bomb is a real, however improbable, risk.

    Greater volatility in precipitation has become a standard, well-established prediction of AGW researchers and analysts.

    First what is , AGW ?

    Its not the precipitation , its the cold .

    Anthropogenic Global Warming.

    It's the precipitation. If water vapor did not precipitate, it could maintain the warmth and even accelerate global warming via feedback - as apparently happened to Venus, almost all of whose surface water exists as atmospheric gas. Since it does, in times of CO2 shortage it cannot even maintain a high enough air temperature to avoid freezing on the planet's surface.

    Cold , snow instead of rain means cold air .

    Actually extreme events are a prediction of global warming of any and all types...cold, hot, floods, droughts etc etc

    Climate change you mean pad .

    The Earth has been through thousands , if not hundreds , of climate changes .

    Climate change and global warming are synonymous
    global warming is a symptom of the more enveloping problem of human induced climate change.

    The Earth has never "been through" what the human boosting of CO2 is doing.
    It's much faster than the "natural" changes of the past, for starters.
    So what did you disagree with?

    This:
    is simply true. The AGW researchers have been predicting more frequently extreme snowfall events, for example. That's because there's more water in the air under AGW.

    Where is the air temp. here ? No where .

    It's the temperature of the air. It's "in" the air.
    What are you trying to say?

    That's a difficult question for river!

    Inotherwords , why is the air cold ?

    What explained the cold , so that snow developed ?

    Jeez!

    Snow is not caused by cold. It is caused by water vapor in the atmosphere moving to an area with a sufficiently low temperature. Warming puts more vapor into the atmosphere so other areas could get more RAIN or SNOW.

    Zero emissions would not reverse the problem. It would take 10 years or more for the planet to reach equilibrium with zero emissions. Reversing the problem would require extracting CO2 from the atmosphere. I do not know how economically feasible that is.

    Winter came, again. It gets cold in the winter, where I live. Lots of other places have winter, also - like Antarctica, or in the middle of large continents. Another place it gets cold is high up on mountains. This is explained in school, or on many yourtube videos, and the like, if you are curious.
