    Notes: Abstract It has been established from geological studies that change in the atmospheric content of carbon dioxide gas commenced about one hundred million years ago. The likely origin of this change is advanced as being the onset of the Brewer circulation caused by the rise in terrain induced by tectonic plate movement. It is demonstrated that tectonic plate movement can be affected by impacts from external bodies which penetrate the crust of the Earth. The consequences of the change in atmospheric concentration of carbon dioxide are proposed as first, extinctions and reductions in animal numbers, including primates, as a result of changes in body chemistry of these animals and second, a change in the rate of weathering of rocks giving rise to changes in the availability of chemicals such as calcium and potassium which are essential for plant and animal life. This latter change contributing to the extinctions and reductions in animal numbers. It is shown that the change in weathering can account for the rise to dominance of angiosperm plants. It is concluded that there were several simultaneous evolutionary environments on Earth which were a function of altitude which gave rise to a vertical variation in atmospheric content of carbon dioxide. This variation disappeared with rise of terrain and the onset of the Brewer circulation. Such changes are advanced and being much more important than any changes in temperature caused by greenhouse effects since the disappearance of atmospheric variations in carbon dioxide allowed animal migration. It is demonstrated that the conditions of extinction could be reintroduced by human activities.

    Keywords: Carbon dioxide ; climate change ; radiant energy production

    Notes: Abstract The present mechanism of radiant energy production in the atmosphere is considered and it is shown that it is not compatible with accepted principles of physics. An alternative mechanism whereby the temperature of the atmosphere and surface of the Earth is regulated by a chemical reaction in the stratosphere is described. It is shown that this mechanism can account for the changes in climate which occurred during the past ten thousand years. The effect on this mechanism of changes in the composition of atmospheric gases, including changes resulting from human activities, is described and the consequences of the changes recorded.
