Natural Factors That Control the Earth's Climate - Myth 5
By Jay Lehr and Tom Harris
The Climate of the Earth has been constantly changing during its entire 4.6 billion year history. Variations in our planet’s average temperature due to natural causes have ranged over a span of 60 degrees Fahrenheit. Most of the periodic temperature increases and decreases observed in human history are consistent with variations in the output of energy from our Sun. The mild heating and cooling periods seen since 1900 (each less than 2 degrees Fahrenheit) reflect changes in solar activity rather than runaway global warming. It is thus a myth that the temperature of the Earth was essentially constant until humans started burning fossil fuels to trigger runaway Global Warming.
Continental positions determine the distribution and circulation of heat on Earth and have a major impact on our planet’s long term Climate. As little as 70 years ago if a child or adult made note of the fact that our current continents could be fitted together like a jig saw puzzle, they were laughed at but in the 1950s scientists proved that in fact our continents had historically resided in different places on the globe. Sometimes the continents were near the equator, sometimes near the poles, sometimes they merged into a single land mass.
Current continental positions are promoting a relatively cold era of recurring Ice Ages. The largest Climate changes take place over time periods of 20 to 100 million years. These changes, both gradual and catastrophic are associated with continental motions due to plate tectonics or continental drift.
Periodic changes in the Earth’s orbit also influence how energy that the Earth receives from the sun is distributed, resulting in our current era of recurring Ice Ages. The Earth is currently experiencing the high temperature end of the latest Ice Age cycle. Both deep-sea sediment and ice core samples show that ice ages take place every 22,000 years. The Earth’s axis wobbles around a tilt angle of zero degrees in a cycle that requires 22,000 years to complete. At one end of the cycle the North Pole faces the Sun in the winter, while at the other end, the North Pole faces the Sun in the summer. The tilt angle relative to the sun also varies over a 41,000 year cycle.The annual orbit of the Earth around the Sun cycles between circular and elliptical every 100,000 years. These are called Milankovich cycles for the Serbian scientist who discovered them a century ago. The reader can easily understand how the temperature of the earth varies widely creating an understanding that man’s presence on the planet and all of it’s activities are insignificant.
Most of the warming and cooling trends observed during human history are related to a third periodic factor influencing our climate. This factor operates on time scales of a ten to a thousand years and resulted in temperature shifts spanning a total range of around 7 degrees Fahrenheit . These shifts arise from the fact that the output of energy and radiation from our Sun is not constant, but changes according to both long-term and short-term cycles of solar activity. These solar cycles, and their connection with the Earth’s climate, have been documented using the recorded history of sunspot cycles, aurora observations, radio-carbon dating techniques, and changes in solar radiance.
Connections between sunspots and solar activity are apparent in changes in the stream of electrons, protons, and alpha particles emitted by the Sun called the solar wind. Increases in the intensity of the solar wind have always been observable in the form of auroras and more recently in the disruption of radio communications and electromagnetic devices. But ancient and modern observations show that there is a direct correlation between the number and intensity of Aurora’s and the sunspot cycle. Solar activity as indicated by the solar wind is the highest when sunspot activity is also highest.
Changes in average global temperature since 1900 are much more consistent with oscillations in solar activity and the average amount of energy that we receive from the sun than they are with the exponential increase in fossil fuel emissions. The Earth’s temperature increased from 1880 to 1935 as the Little Ice Age ended. It decreased from 1935 to 1980 and increased from 1980 to 1990 and has since leveled off. The temperature did not continuously and dramatically increase to mirror the increasing CO2 emissions.
Global warming advocates would like you to believe that the use of fossil fuels is an environmental disaster equivalent to the asteroid that ended the rule of dinosaurs on our planet. Fortunately for humans, the only real disaster is the extent to which the media, our schools, and climate change scientists have ignored, modified, and falsified climate data to promote a purely political agenda. The Vikings and other ancient human populations would be surprised to learn that they never lived through the Medieval Warm Period or the Little Ice Age. The cooling period that lead Time Magazine in 1977 to warn of an impending Ice Age, absolutely positively never happened. Instead, everyone is supposed to believe that the Earth’s temperature was always constant but is now increasing by up to several degrees per year due to fossil fuel emissions. It just isn’t true. The extensive rewriting of climate history represents the most pervasive and damaging example of scientific fraud in the history of mankind.
