Global warming is s shibboleth of the modern day. Here in Oregon, a few years ago the governor punished the chief climatologist of Oregon State University with excommunication (its equivalent) for insisting in the face of the dictates of current faith, the equivalent of the earth moving around the sun.
Without citing references the partisans claim that the earth has warmed two degrees Fahrenheit in the last 100 years and seven degrees Fahrenheit since the last ice age. I say equally without supporting references that Greenland ice cores show that during the last ice age, global temperatures varied through twenty degrees centigrade in the space of one year except I can provide references and will at a later date.
These same partisans attribute global warming to human activity as evidenced by the conversion of forest to farmland, but from the end of the last ice age, until the Holocene period, far more forest land in Europe was converted into savanna by naturally occurring global warming.
The consequences of global warming are climate change. Patterns of erosion on the Egyptian sphinx indicating water flow and extinct tropical coral reefs off the coast of Norway, coal deposits in Antarctica and mammoths frozen solid in ice in Siberia so that their meat was fresh and edible as was the vegetable material in their teeth and stomachs show that the earth has undergone far greater warmings and coolings and far quicker than a few paltry degrees per century. Again I can provide references and will at my convenience, I just want to illustrate how the partisans for global warming throw out supposed data just as some religious leaders throw out historical data without any backing. Just how much we are talking about articles of faith here is exactly my point.
Forty years ago ecologists made dire predictions, but better forest and farmland management resulting in greater productivity prevented a catastrophic explosion of the population bomb. It was not that Thomas Malthus was wrong, it was just that man helped nature to set a bigger table. Still it moves!
Global warming 55million years before the present, is evidenced by a sediment layer whose carbon is unusually rich in the carbon-12 isotope (light carbon) indicates a massive release of methane from oceanic methane hydrate.
Temperature variation is normal, because an ice age is really the earth’s answer to global warming to wit large massive sheets of ice do not form as a result of colder temperatures. Ice draws moisture out of the air. Frost is the result of cold temperatures. Large massive sheets of ice are the result of snow pack. Snow piled upon snow piled upon snow piled upon snow. For a glacier to form, there must first be tremendous amounts of precipitation. A prerequisite of precipitation is evaporation, A prerequisite of evaporation is increased molecular motion of water molecules. Motion will not increase without an influx of energy. Ergo, an ice age evidenced by massive glaciation without a prior enormous heat wave will not occur. Such a heat wave could occur as a result of an asteroid strike with a resultant shock wave traveling through the earth’s crust, disrupting tectonic plates, initiating global volcanic activity. Whether large increases in atmospheric water vapor without volcanic smoke would lead to increased snowfall or more greenhouse effect remains to be seen. But the decrease of global temperature as a result of the K-T event (evidenced by a deposition layer of iridium ash) has as its mirror image the Permian extinction whose deposition layer of light carbon indicates global temperature from a massive methane release either from a cometary strike or a release into the atmosphere of seafloor methane hydrate.
