    His rejection of global warming is based on failure of the Great Depression to cause a fall in terran CO2 levels.


    Now imagine two lines on a piece of graph paper. The first rises to a crest, then slopes sharply down, then levels off and rises slowly once more. The other has no undulations. It rises in a smooth, slowly increasing arc. The first, wavy line is the worldwide CO2 tonnage produced by humans burning coal, oil and natural gas. On this graph it starts in 1928, at 1.1 gigatons (i.e. 1.1 billion metric tons). It peaks in 1929 at 1.17 gigatons. The world, led by its mightiest power, the USA, plummets into the Great Depression, and by 1932 human CO2 production has fallen to 0.88 gigatons a year, a 30 per cent drop. Hard times drove a tougher bargain than all the counsels of Al Gore or the jeremiads of the IPCC (Inter-Governmental Panel on Climate Change). Then, in 1933 it began to climb slowly again, up to 0.9 gigatons.

    And the other line, the one ascending so evenly? That's the concentration of CO2 in the atmosphere, parts per million (ppm) by volume, moving in 1928 from just under 306, hitting 306 in 1929, to 307 in 1932 and on up. Boom and bust, the line heads up steadily. These days it's at 380. There are, to be sure, seasonal variations in CO2, as measured since 1958 by the instruments on Mauna Loa, Hawai'i. (Pre-1958 measurements are of air bubbles trapped in glacial ice.) Summer and winter vary steadily by about 5 ppm, reflecting photosynthesis cycles. The two lines on that graph proclaim that a whopping 30 per cent cut in man-made CO2 emissions didn't even cause a 1 ppm drop in the atmosphere's CO2. Thus it is impossible to assert that the increase in atmospheric CO2 stems from human burning of fossil fuels.

    No-no-no.  

    More cars were on the roads, trains continued to roll, more people were born, and on and on. The industrial uses of fossil fuel are important, but that's not the whole of what happens.

    The figure given, here, for CO2 emissions is a proxy for total CO2 emissions. It is not a measurement.

    BTW: Cockburn is pronounced "coe burn."

    Despite the obvious.....
