    fc you keep point to the oceans warming

    1. you models said man made co2 warmed the air... not the oceans.

    2. there is no science showing man made co2 is have an influence on oceans warming.

    3. Oceans release co2 when the warm.

    4. Scientists are just not wondering if underwater volcanoes are doin the warming.


    What we do know is that man made co2 is just of sliver of co2.
    Co2 is just a percent or so of greenhouse gases and that water vapor has far greater influence of warming and cooling.


    So you have no science right now because your models failed.

  3. CO2 from man, far from being a sliver, is about 40% of the current atmospheric concentrations.

    CO2 from man is being absorbed by the oceans.

    Yes the models are for the atmosphere. So what. They have not failed. Current trends would have to continue for many more years before that can be said. Are they inadequate? Yes. Again. So what? The essential point is the earth as a whole has not stopped or even slowed warming.

    They know the extra CO2 is from man via simple math and isotope analysis. It's not from volcanoes. You're grasping at straws.

    A single recent volcanic eruption wiped out/offset the entire European carbon reductions.

    1. please explain... with a link what you mean... with this 40% midirection.

    man mad co2 is just a tiny sliver of greenhouse gases in the atmosphere... so if there is even a hint of truth in your statement... it must be some sort leftist/clintonian misdirection.

    2. the earth may or may not of stopped warming... but the point is you have no science showing the ocean warming is not part of natural variability. Which is the whole point of this discussion.

    a. the earth may be warming... (it may be cooling too... when you are inside the all time high or low... trends are just definitions of recent data.

    b. what we do not want is a govt take over of production via carbon exchanges, cap and trade and tax schemes designed to bring more power to leftist big govt types.

  6. See, the problem with you is that you are right wing fanatical whack job first above all else. You ignore and fabricate the science to suit.

    It's simple. 40% of the atmospheric CO2 is from man. All of the warming over the last fifty is from this extra CO2.

    first of all even the agw nutter websites say man made co2 is only 7% of current co2 in the atmosphere.

    next... even if your unsupported quote were correct, it was a mis direction because man made co2 it is still only a tiny sliver of greenhouse gases. It was not 40% of atmospheric concentrations.

  8. While CO2 absorption and release is always happening as a result of natural processes, the recent rise in CO2 levels in the atmosphere is known to be mainly due to human activity.[24] Researchers know this both by calculating the amount released based on various national statistics, and by examining the ratio of various carbon isotopes in the atmosphere,[24] as the burning of long-buried fossil fuels releases CO2 containing carbon of different isotopic ratios to those of living plants, enabling them to distinguish between natural and human-caused contributions to CO2 concentration.


    This addition, about 3% of annual natural emissions, as of 1997, is sufficient to exceed the balancing effect of sinks.[30] As a result, carbon dioxide has gradually accumulated in the atmosphere, and as of 2013, its concentration is almost 43% above pre-industrial levels.

    43% percent greater than pre industrial levels... is not 40 percent of atmospheric concentrations.


    you either just lied your ass off or you goofed most basic understandings. Something which should have been a pre requisite to putting up all these posts and calling names.

  10. Somewhere around 40% of the atmospheric concentrations of CO2 can be attributed to man, since without man they would be 40% less. Is that clearer to you?
