If Bill's instructions are a success at vastly reducing manmade greenhouse gases (note that if it's something bad, it's still called manmade rather than humanmade), I look forward to his step-by-step analysis on avoiding an ice age.
See, that was the whole point of manmade greenhouse gases, as far as Svante Arrhenius was concerned -- Arrhenius being the first scientist to "use principles of physical chemistry to estimate the extent to which increases in atmospheric carbon dioxide are responsible for the Earth's increasing surface temperature" according to Wikipedia. But he undertook his study in a quest to understand how ice ages happened.
After getting his point across in German and at least one other language, in 1908 he went to the English-speaking public. In his book, "Worlds in the Making" he wrote:
"We often hear lamentations that the coal stored up in the earth is wasted by the present generation without any thought of the future, and we are terrified by the awful destruction of life and property which has followed the volcanic eruptions of our days. We may find a kind of consolation in the consideration that here, as in every other case, there is good mixed with the evil. By the influence of the increasing percentage of carbonic acid in the atmosphere, we may hope to enjoy ages with more equable and better climates, especially as regards the colder regions of the earth, ages when the earth will bring forth much more abundant crops than at present, for the benefit of rapidly propagating mankind." (p. 63)
Past Climate Cycles: Ice Age Speculations:
[...]The calculations were backed up in 2004 by data from a heroic new drilling effort in Antarctica that brought up ice spanning the past eight glacial cycles. Among these was an unusually long previous cycle where the orbital elements had been similar to those in our own cycle. On the other hand, in 2012 a team using a different ancient cycle as an analogy to the present claimed that the world should indeed be descending into an ice age within the next few thousand years.(53*)The scientists who published these calculations always added a caveat. In the Antarctic record, atmospheric CO2 levels over the past 750,000 years had cycled between about 180 and 280 parts per million. The level by 2012 had climbed almost to 400 and kept climbing. (The other main greenhouse gas, methane, was soaring even farther above any level seen in the long ice record.) Greenhouse warming and other human influences seemed strong enough to overwhelm any natural trend.
One scientist, paleoclimatologist William Ruddiman, even argued that the rise of human agriculture had already produced enough greenhouse gases to counteract the gradual cooling that should have come during the past several thousand years; every previous cycle had begun a steady cooling soon after its peak, rather than leveling off as ours had done.(53a) As emissions climbed exponentially, we might not only cancel the next ice age but launch our planet into an altogether new climate regime.[...]
