The EF-5 tornados in Oklahoma last month were a stark reminder of how dangerous nature can be. The massive twisters sported winds in excess of 200 mph and were responsible for taking the lives of over 30 people. Sadly, it didn’t take long for some to decry the dangers of climate change. But was this the result of man-made global warming (MMGW)?
Temperatures have always fluctuated higher and lower; but since they have stalled for the last 16 years climate change alarmists have resorted to cries of “extreme weather” such as tornados as proof of MMGW. But this claim does not fit the data.
According to the U.S. National Climatic Data Center, the number of severe tornados categorized as EF-3 to -5 has been decreasing since 1950 that some have labeled as a tornado “drought”. Furthermore, NOAA estimated between May 2012 and April 2013 the U.S. experienced the fewest tornados ever recorded. All of this during a time when hydrocarbon use such as oil and coal has increased dramatically, and CO2 levels are at modern-day highs.
However, this is not the only evidence against MMGW. In fact, I don’t have enough room to address all the evidence, so I’ll concentrate on historical CO2 and temperature trends in this article.
CO2 is a trace gas making up about 0.04% of the Earth’s atmosphere. This means there are about 400 molecules of CO2 for every million molecules that make up our atmosphere; or 400 parts per million (PPM). Man has been contributing to the production of this trace gas since the industrial revolution 200 years ago; but more significantly since the buildup of the military industrial complex in the 1940s. Overall, man-made CO2 (MMCO2) has helped increase the global concentration of CO2 from about 280 to our current 400 PPM. So, how has this affected temperature?
Since 1998: Although our rate of production of MMCO2 has leveled off since the 1990s, today we are experiencing the highest levels of CO2 concentration in the last 200 years. Despite this increase, NASA recently admitted we have been experiencing “flat-lining temperatures” for the last 16 years. Ironically, climatologist’s computer models were predicting an increase of almost five degrees Fahrenheit over this same period.
Since 1940: We have experienced a dramatic increase in MMCO2 due to a six-fold increase in the use of hydrocarbons. But instead of temperatures increasing, they actually decreased through the 1970s. Because of this, climate change alarmists were frantically claiming we were headed for another ice-age through “global cooling”.
Since 1850: According to the Oregon Institute of Science and Medicine, four independent temperature records (Northern Hemisphere, Arctic, global, and U.S.) have qualitatively confirmed each other by exhibiting three intermediate trends – warmer, cooler, and then back to warmer. Contradictory to MMGW theory, the cooling trend covered a period of time when hydrocarbon use exploded by 330%. But the most amazing coincidence related to these four independent temperature records is that they correspond perfectly with solar activity over the same period. In other words, temperature changes were not driven by CO2 levels but by the sun.
A.D. 900 to 1200: Long before the production of MMCO2 we experienced a period of time referred to as the ‘Medieval Warming Period’ where temperatures were approximately two degrees Celsius higher than they are today. According to climate change alarmists this period of increased temperature should have wrought chaos and devastation. Instead, not only do polar bears still exist, evidence indicates we experienced much more vegetation and prosperity during this time. For example, excavations of Greenland show that it was much greener than it is today; which in turn enabled the Norse to establish settlements there in the late A.D. 900s.
Warmer weather increases atmospheric concentrations of CO2, extends growing seasons, and therefore improves the habitability of colder regions. Why? Because CO2 is not a pollutant but a fertilizer. Plants use CO2 through photosynthesis to grow and produce oxygen. Thus, higher temperatures equal more CO2, which means more vegetation, more life, more food, more habitable regions, and more prosperity.
Lastly, during the Paleozoic and Mesozoic periods CO2 levels were much greater than they are today; at one point almost 20 times greater (geocraft.com). If MMGW theory is correct there should have been runaway greenhouse induced global warming during these periods. Instead, overall temperatures were no warmer than they are today; but more interesting is the fact that these periods experienced two glaciations. Even more interesting is the fact that atmospheric CO2 concentrations were sharply decreasing as the two glaciation periods were ending.
Future articles will address more of the evidence against anthropogenic global warming. However, due to the erroneous belief that man is the cause of climate change we find ourselves almost paralyzed to drill for new domestic sources of energy despite the fact that we are finding enough hydrocarbons to sustain us for generations to come. As a result we have become energy-dependent and send hundreds of billions of dollars to countries that hate us. This is not only unsustainable, but costs us millions of jobs here at home. It’s time to stop this nonsense.
