Global Warming Could be Caused by the Earth’s Natural Temperature Cycles
Posted on: Thursday, August 29, 2013 Comments
According to the prediction of an Ohio State University researcher, global warming is a natural geological process that could begin to reverse itself soon. According to this prediction, within the next ten to twenty years, the earth may reach its peak in the current temperature profile cycle and then begin to cool toward a new ice age.
An Ohio State researcher conceded that atmospheric carbon dioxide, often thought of as a key "greenhouse gas" is definitely not the cause of global warming. In fact, according to Robert Essenhigh, E.G. Bailey Professor of Energy Conservation in Ohio State's Department of Mechanical Engineering, it’s the rising global temperatures that are naturally increasing the levels of carbon dioxide and not the other way around.
Although many people blame global warming on carbon dioxide sent into the atmosphere from burning fossil fuels in man-made devices, Essenhigh’s conviction clearly states that these people fail to account for the much greater amount of carbon dioxide that enters as well as leaves the atmosphere, as part of the natural cycle of water exchange from the sea and vegetation.
To prove his hypothesis, Essenhigh has examined data from various sources, including measurements of ocean evaporation rates, man-made sources of carbon dioxide, and global temperature prediction data for the last one million years.
Essenhigh’s research demonstrated how the global temperature system works. He explained that as temperatures rise, the carbon dioxide equilibrium in the earth’s water changes,
and this releases more carbon dioxide into the atmosphere. Therefore, according to this scenario, atmospheric carbon dioxide is then an indicator of rising temperatures, not the
driving force behind it.
Essenhigh attributes what he calls the current reported rise in global temperatures to a natural cycle of warming and cooling.
Also, admitting that the earth is not really warming much, Cambridge University geologists Nicholas Shackleton and Neil Opdyke agree that the average global temperatures have risen less than one degree in the last million years. Essenhigh explained that "Today, we are simply near a peak in the current cycle that started about 25,000 years ago," Essenhigh explains that the Arctic Ocean acts as a giant temperature regulator, an idea known as the "Arctic Ocean Model." This model first appeared over thirty years ago and is well presented in the 1974 book, ‘Weather Machine: How our weather works and why it is changing’, by Nigel Calder, a former editor of New Scientist magazine.
According to this model, when the Arctic Ocean is frozen over, as it is today, Essenhigh says that it prevents evaporation of water that would otherwise escape to the atmosphere and then return as snow. So, when there is less snow to replenish the Arctic ice cap, the cap may start to shrink; and that could be the cause behind the retreat of the Arctic ice cap that scientists are documenting today, states Essenhigh.
As the ice cap melts, the earth warms, until the Arctic Ocean opens again. Once enough water is available by evaporation from the ocean into the atmosphere, snows can begin to replenish the ice cap. At that point, the Arctic ice begins to expand, the global temperature can then start to reverse, and the earth can start re-entry to a new ice age.
