Personal Thoughts On Global Warming
What is global warming? Is it possibly the greatest threat to all of Earth’s population, nonhuman and human? Or, is it the greatest hoodwink that has ever been conducted? Many scientists have been wondering if the data is supported enough to jump onto the bandwagon or not. There are many people writing about this topic. It seems that this is either a real life threat or just a way for certain individuals to get money and power for themselves. There really is no argument if the Earth is actually warming, it is, but the argument is if this warming is caused by us humans, or is it caused by normal orbital rotations around the sun? The point that needs to be made is this; if there is actual evidence showing that this is such a huge problem then let it be put forth, and let it not be twisted to fit a certain way. If actual evidence is being twisted to fit a certain view then that is not evidence at all, but it is just putting forth lies that is masquerading as evidence.
In the article Toward a Critical Anthropology on the Impact of Global Warming on Health and Human Societies, Baer talks about certain things that need to be changed. “ It is obvious that human societies will have to adapt to the reality of global warming in a variety of ways, including technological fixes, reliance on renewable energy sources, less reliance on cars and airplanes for transportation, improvement of mass transit systems, more efficient forms of heating and cooling, the development of buildings and dwelling units that are more energy efficient, the redesign of cities, simpler patterns of consumption, and health facilities to deal with diseases of global warming.” (Baer, Pg. 3) This quote does not have that much “meat” backing it up. This quote may be true if Global Warming was actually as serious as this article is making it out to be. After Baer said this, there was no evidence saying how much pollution from our vehicles is actually contributing to the Global Warming problem. These words might carry more leverage with that evidence but without it, all it is just an opinion or point of view of an individual.
In the article Global Warming and Earth’s Design, Wayne Spencer shares some insightful information. “Recently there has been a growing scientific voice against the warnings of the global warming community. Recent scandals, such as “climategate” and questionable practices of the Climate Research Unit at East Anglia University, have raised new doubts about the conclusions of climate scientists.” (Spencer, Pg. 1) Spencer makes an interesting point here. There have been many “causes” and “companies” started that claim to work towards finding a solution to the Global warming problem, but in reality they are just taking people’s hard earned money and keeping it for themselves, or using it for other scrupulous activities. Some of the information that Wayne Spencer also gives in his article has to do with greenhouse gases and it is worth repeating here.
“There has indeed been a warming of earth’s climate, though the amount of warming is still debated. But the key questions are (1) could mankind be to blame? (2) could any actions taken by mankind really make a difference? and (3) will the climate change resolve itself without mankind’s help? First of all, advocates of global warming being a serious problem treat carbon dioxide as if it were a pollutant, but it really isn’t. Carbon dioxide is a natural constituent of earth’s atmosphere (about 0.04% of all atmospheric gases; methane and CFCs are much less), although it is true that it is one of a number of “greenhouse gases.” A greenhouse gas is a substance that allows light to transmit through the atmosphere to the surface, but which absorbs radiant energy escaping back out through the atmosphere. The overall process tends to convert mostly visible light from the sun to infrared, which heats the atmosphere. Light is able to pass through the atmosphere to earth’s surface, but the surface reradiates the energy at longer wavelengths in the infrared that get absorbed by the greenhouse gases in the atmosphere. When the infrared is absorbed on its way out of the atmosphere, this heats the atmosphere and affects our climate. However, carbon dioxide is not the most important “greenhouse gas” in earth’s atmosphere. The great majority of the greenhouse effect in earth’s atmosphere is from water vapor. Water vapor often changes state from gas to liquid or to solid. Its form and concentration also vary with humidity and cloud cover, thus its effect on climate and weather is extremely complex. It is very difficult for scientists to predict how water vapor might affect the temperature of earth’s atmosphere as a whole. Predicting global climate from climate computer simulations, especially over long periods of time, may be beyond what our methods are capable of at this time. There are many types of effects that scientists do not know how to model accurately in computer simulations, such as effects of different types of clouds, the presence of snow and ice, ocean surface effects, etc.” (Spencer, pg. 2)
The above quoted material presents a good contrast to the carbon dioxide gas compared to the water vapor. It correlates very well with actual evidence found, and it makes more sense when you realize how much more water vapor is present compared to the carbon dioxide gas. Like the article mentions, it is very hard to predict how much damage that the large amount of water vapor is having on our atmosphere due to the relatively short amount of time that we have recorded and been studying this problem.
Wayne Spencer also gives another aspect to how this warming is being contributed to Earth through the Sun’s rays. “The sun has very complex magnetic fields that affect our weather. Sunspots are formed in magnetic eruptions on the sun. The more sunspots, the stronger the sun’s magnetic field is and the more it deflects galactic cosmic rays. Galactic cosmic rays are charged particles that come from outside our solar system. These consist of a variety of charged subatomic particles. There are also charged particles that come from our sun. The charged particles from the galaxy and from the sun constantly flow through our solar system and affect earth’s upper atmosphere and thus our weather. Cosmic rays seem to be related to how much low-level cloud cover there is through a complex series of particle effects in earth’s atmosphere. When there are more frequent sunspots, the cosmic rays reaching earth are fewer. Fewer cosmic rays mean less low-cloud formation, and this allows the ocean and lower atmosphere to be warmed slightly. Thus, if the reverse occurs, the sun’s magnetic field being weaker (fewer sunspots) leads to more intense cosmic rays penetrating earth’s atmosphere, generating more low-cloud cover over the oceans and this cools the lower atmosphere. This is all relevant to the global warming issue, because the sun has recently been in a period of intense magnetic activity known as a grand maxima. This grand maxima has lasted from approximately 1940 to 2000. This maxima is likely to have caused some slow warming of earth’s atmosphere.” (Spencer, pg. 3) This is a very intriguing idea, because when you think about it, if this grand maxima is true to reality, then that would mean that humans are not completely responsible for the warming of our atmosphere, and if that is true then global warming information that is being put out with us, human beings, as the main problem would result in an unprecise conclusion.
The research for this problem is ever ongoing, and one has to wonder if scientists will ever agree upon a solution that they see eye to eye with each other. In an article by Shaun Mckinnon titled, Skeptics Raise Doubts on Global Warming, he has this to say. "The public often sees theory as synonymous with opinion or a best-guess hypothesis," he said. "That's unfortunate. It takes away from how much we know. Scientists are comfortable with a certain amount of uncertainty. Uncertainty with scientists is a creative force. It makes you ask more and more questions." (McKinnon, Pg. 2) It is unfortunate that people believe things that are not fully researched yet. That is why certain individuals heavily involved in Global Warming are pocketing millions of dollars for evidence that I believe is faulty. It is strange that it has been years since we have begun “researching” Global Warming, but we still have no “proper” way to take care of it.
I do not believe in Global Warming being only the human populations fault, but I do believe we have contributed to it in part. Some of the carbon dioxide that we have released into the atmosphere may be increasing the thickness of the water vapor which would result in some higher temperatures on Earth, but it is not completely our fault. Also, with the possibility of Grand Maxima it seems to make sense that through this process Earth has also warmed by a small fraction. At the moment, it seems that we are still at an impasse as to what is the proper solution to take to combat this problem. But, as scientists, one must realize that you cannot make evidence fit your view, it must be presented with as little bias as possible. I stand with Wayne Spencer on his views of Climate Change, because it makes the most sense to me and seems to correlate the best with current research.
