  1. Jørgen Peder Steffensen is a professor of ice, climate and geophysics at the Niels Bohr Institute and one of the researchers behind the discovery.

    “The gradual cooling appears to be caused by continental drift: Antarctica become isolated at the South Pole, the Himalayas were formed and the Isthmus of Panama appeared out of the sea (2 million years ago). With the current configuration of the continents the earth is apparently susceptible to climate effects through variations in the earth’s orbit around the sun (the so called Milankowich theory). Over the last 40 million years the CO2 level in the atmosphere has fallen from 1000-2000 ppmv to a minimum of 180 ppmv 20.000 years ago.
    Not since the Perm period circa 250 million years ago has the CO2 level been so low.
    One can conclude that man had nothing to do with the end of the ice age. CO2 and climate continued to change at the same rate until industrialisation. I could be worried that our CO2 emissions could very well go and have serious consequences; but one should not believe that nature will just remain at rest if we let it be: Ice ages and climate ripples are good examples that nature is neither environmentally neutral or politically correct.

    Whenever I post this You Tube for the anthropogenic climate change alarmist to view they seem to take exception to what Jørgen Peder Steffensen is maintaining about the Earth being 2.5⁰C 4,000 years ago than what it is now. These are the same ones that have no problem with Michael Mann eliminating the well documented MWP with his hockey stick graph.
