EARTH'S CLIMATE and CO2
March 20, 2008 (original release date)
The Global Warming phenomenon currently being splashed across the world stage, and it’s introduction being blamed solely on anthropogenic activities (to include the CO2 and methane our bodies emit), is more than just a theory, it is a fantasy with no ties whatsoever to reality or proven empirical science.
While it can be argued that the Earth is warming slightly, the data supporting this summation is based on the study of, essentially, very small ripples on the much larger wave representing the cyclic rise and fall of global temperatures. Temperatures that are just about due to rise again, a theory based on the known history of Earth's climate changes.
There is no data to prove that green house gases are warming the planet, only some percieved relations and theories as to relevance. This planet is actually very near the lowest recorded average global temperature, which fluctuates a full ten degrees centigrade (C) at relatively regular intervals over more than 550 million years spanning some of the Earth's known history. The average global temperature consistently rises from approximately 12 degrees C, to around 22 degrees C during a relatively short period (5 to 10 million years average but up to 30 million), and then remains there for between 75 and 150 million years before it begins the decline over a nearly identical timeline as the previous rise. The temperature only remains at the low average for about 2 to 6 million years (with a few exceptions) before once again rising to the average high. All this while the CO2 in the atmosphere is constantly dropping.
It is a non-disputed fact (albeit largely ignored) that the Earth has been in a cooling stage for the last 40 million years (with no relation to atmospheric CO2 levels) and is likely at, or near, the end of it; how long it will remain there is presently not known. The small flutcuations encompassing mere thousands of years, that we are noticing now, are negligible. A rise in global temperature and CO2 could likely occur over the next five to ten million years, in line with the historically proven cyclic activities of this planet, and there will be nothing mankind can do about it but adapt. Moreover, core samples from Antarctic ice sheets show that atmospheric CO2 levels rise following a warming trend, not preceding one, indicating that CO2 levels are, most likely, directly affected by geothermal variances, rather than vice versa.
In the history of our planet the CO2 levels have been falling for over 500 million years, with a relatively moderate rise occurring and then falling again during the Mesozoic era (a period of around 200 million years). CO2 levels in the atmosphere peaked just over 540 million years ago during the Cambrian period at approximately 7000 ppm (parts per million), a level nearly twenty times the approximately 350 ppm present in the atmosphere today. These levels began dropping sharply and continued over the next fifty million years into the Ordovician period where they stabilized slightly at around 4000 ppm, all while the mean global temperature remained unchanged at approximately 22 degrees centigrade (C).
At midpoint in the Ordovician period there is a slight increase in CO2 levels (300 ppm) to around 4300 ppm over a period of about twenty five million years, which is sharply contrasted by a simultaneous drop in global temperature of more than 10 degrees, to around 12 degrees C.
What is also quite notable is the fact that there is apparently no evidence throughout this planet’s history to suggest that these changes had any significant negative effect on animal or plant life.
During the Silurian period, over the next twenty million years, CO2 levels show another marked decline from 4300 ppm to around 2800 ppm, and are once again converse to a simultaneous increase in average global temperature from 12 degrees C to 22.3 degrees C.
Increasing by over 1500 ppm during the next twenty million years of the Devonian period (about 385 million years ago), CO2 levels, again reaching over 4300 pmm, prove to have virtually no effect on the average global temperature, as it remains largely unchanged at around 22 degrees C.
Throughout the latter half of the Devonian period and throughout the Carboniferous period to midpoint in the Permian period, a span of approximately 120 million years, atmospheric CO2 levels (4300 ppm) declined markedly, bottoming out at around 300 ppm (below the levels we see today), while temperature levels first stabilized at approximately 20 degrees C before also plunging, midpoint in the Carboniferous period, to 12 degrees C (and below) over a five million year period, remaining there for about 30 million years.
During the next 15 million years both CO2 and temperature levels increase sharply with average global temperatures hitting their historic peak of over 23.1 degrees C, while CO2 levels fall off the pace, topping out at a relatively moderate 1900 ppm.
Throughout the Triassic and most of the Jurassic and Cretaceous period’s (approximately 200 million years) the atmospheric CO2 and temperature levels do a contrasting dance, with CO2 levels fluctuating between 1200 and 2600 ppm, and eventually falling to 700 ppm where they continued their decline over our present Tertiary period of the last 70 million years to current fluctuating levels of approximately 350 ppm. In unison with the CO2 level reduction over the last 70 million years, mean geothermal levels have also declined, returning to their overall lows of around 12 degrees C.
Throughout the entire Paleozoic, Mesozoic and Cenozoic era’s there is not one shred of evidence to support the theory that CO2 levels have any affect on global temperature, and certainly not on climatic weather patterns, however, there is some data to suggest that global temperature may have some relative effect on Carbon Dioxide levels in the atmosphere.
Rather than acting as paid shill's for the corporate elite's secret agenda's, scientists should be focusing their attention on researching just how humanity may need to adapt to recurring, long term, climate change.
