U.S.A. –-(Ammoland.com)- In the early 1900s humans started producing greenhouse gasses.
The question is does the .28% to 5.53% of extra greenhouse gases that human produce really change the earth?
Many people argue that human made global warming is a fact. People claim human caused global warming cannot be debated, but before the debate can be over we must look to climate change in the past and look at other theories. Through the introductions of these theories and a look back at history we can show that the debate is far from over.
In 1975, Newsweek reported a damning article on climate change.
“There are ominous signs that the Earth’s weather patterns have begun to change dramatically and that these changes may portend a drastic decline in food production – with serious political implications for just about every nation on Earth. The drop in food output could begin quite soon, perhaps only 10 years from now.” Newsweek continues “The evidence in support of these predictions has now begun to accumulate so massively that meteorologists are hard-pressed to keep up with it.” [Newsweek, April 28, 1975]
If this article appeared today most people were assume it was about global warming, but the article was about global cooling. Just like today with global warming, in the seventies many claim the debate on human made global cooling was over.
Climate change has happened throughout the history of the earth. In 800-1300 AD temperatures began to rise. This period of time was known as the “Medieval Warming Period”. Humans produced very little greenhouse gases at this time yet the temperature increased around the world.
This was not the only time temperatures have changed drastically. Starting in the 1400s and lasting to the 1700s the earth was in the “Little Ice Age”. Temperatures dropped across the planet. The canals in Holland froze over crippling the Dutch economy. In the Alps glaciers advanced. These changes prove that climate change is not exclusive to the post industrial revolution earth.
NASA has run computer models to determine the cause on the drop in temperature that caused the “Little Ice Age”. The most likely cause of these drastic changes was solar activity. During the “Little Ice Age” solar activity was at a low point. NASA studies show when solar activity slows down the temperatures on Earth drops. NASA studies also show when solar activity speeds up the temperatures on Earth rise. Currently solar activity is at the higher level than any time in the last 8000 years. If we know an increase in solar activity causes the Earth to warm, and solar activity is at an 8000 year high, it could be that the major factor in global warming is solar activity.
Solar activity in the past has warmed the Earth, and we now must take into consideration the role of the sun in global warming today.
To see if the solar activity theory holds up scientist need to look at other planets. The Mars Global Surveyor and Odyssey missions have shown that the temperature on Mars has also increased. This shows that two planets are warming with solar activity being the only common link. While the Earth could be affected by humans, but Mars is not. The theory is strengthened by the fact both Mars and earth have seen ice ages. The scientists who believe in the solar activity theory view this as a “smoking gun”.
Carbon dioxide is seen by human produced global warming theory as the gas that is the cornerstone of global warming. We do know that carbon dioxide is a greenhouse gas, but there is another more powerful greenhouse gas that accounts for global warming. Richard Lindzen, of the Massachusetts Institute of Technology, testified in front of congress on May first 2001 against the Kyoto Treaty that carbon dioxide is not the important gas in global warming. He argued that water vapor is the cause of global warming.
Professors Lindzen points out that even if carbon dioxide levels doubled the mean temperature of the earth will only increase by two degrees Fahrenheit. His research also brings to light that this warming would be most likely present in the winter and at night. If Lindzen is right this would have a beneficial effect.
Professor Lindzen also brings up a point that human caused global warming advocates have a hard time defending. The computers that are used to model global warming trends cannot simulate climate changes in the past correctly. The computer models are getting changes in the past wrong; however we are supposed to trust these same models to predict future climate changes. The computer models should not be trusted until they can predict changes in the past successfully.
In 2006 Al Gore produced the flagship of global warming media. He produced a documentary called “An Inconvenient Truth”. This documentary claimed to show how global warming is caused by humans. It uses large amounts of facts and statistics to “prove” the documentaries point, but once one peels back the layers of the documentary we find that data that was used was misrepresented.
In the “An Inconvenient Truth” it is claimed that the Medieval Warming Period was small compared to modern warming. The documentary uses ice cores taken by Glaciologist Lonnie Thompson. The documentary used data that was based on two ice cores. There were multiple ice cores samples taken, and all but the two used showed that the Medieval Warming Period was warmer than the modern period. The two ice cores that were used were most likely contaminated. Al Gore’s production company was notified by Lonnie Thompson of the error, but they choose to use the samples any way.
According to “An Inconvenient Truth”, the rate of global warming is accelerating. The facts do not support this. The rate of warming has been constant over the past 100 years. The documentary does not give a source for their data, but their numbers are not the widely accepted figures.
Al Gore is the driving force behind “An Inconvenient Truth”. The documentary pushes a “cap and trade” system. This is where caps would be set on emissions. If a company goes over the cap the company would have to buy “carbon credits” from other companies that pollute less. Al Gore is also the co-founder of Generation Investment Management. This company is set up to sell carbon credits. If the system Al Gore is proposing is implemented, Al Gore stands to make billions.
The debate on global warming is far from over. As science advances we will be able to learn more about climate change and be able to make more informed decisions. As for now, the science is not there to be able to close the debate on global warming.
