    A climate scientists view.

    Climate Change: The Next Generation: Andrew Glikson: Planetary Boundaries (CO2 equivalent of 460 ppm has been surpassed

    In my view an upper limit of 450 ppm CO2, proposed by a range of reports by government organizations, including the Garnaut Review [5] and the Australian Government White Paper [6], can not be sustained, for the following reasons:

    A. The atmosphere has already transcended the CO2-equivalent (including the forcing of methane) level of 460 ppm.

    B. A level of 450 ppm CO2 is a mere ~40 ppm below the upper boundary of ~500 ppm, which is the upper limit of stability of the Antarctic ice sheet, formed about 34 million years ago. In the Pliocene, 3 million years ago, a CO2 level of 400 ppm led to temperature rise of about 23 oC and sea level rise of 25+/-12 meters.

    C. There is no evidence that the climate can be stabilized at such high level of greenhouse-induced forcing. Due to carbon cycle feedback loops and feedbacks related to ice melt/water interaction, CO2 level of 450 ppm may lead to yet higher greenhouse levels, high temperature levels and possible tipping points.

    D. Not taken into account in many projections are looming emissions of methane, which are already taking place under atmospheric CO2 levels of 388 ppm, or CO2-e levels of 460 ppm.

    old crock your a lousy cock sucking brain damaged asshole. why wont you post the report in your other thread, 100% alternative energy,

    you call others dumb for not buying a magazine to see the article you cant even post despite your using the article as your source.

    Every link I follow of OLD CROCK's is either a press report or proves old crock wrong,

    Old Crock your own sources state you are wrong

    how much you drink tonight you old crocked drunkard

    CO2 does not store heat, CO2 does not emit heat, CO2 stores cold energy, yea thats right. CO2 stores coldness.

    Dry ice is pure CO2, go buy some and conduct an experment.

    CO2 is dry ice

    Dry ice is CO2

    watch the debate change after a cold winter or two

    Spamming all the same crap from the same crap site over and over again does not science make, and convinces no one of anything other than your obvious mission of flooding and just general crappery.

    Hell ... there's still less CO2 in the atmosphere than mold.

    letting go of a debunked theory is hard. Globull Warming was a religion. A dead one. R.I.P.
