The Real Cause of Global Warming
There are many scientists who say that humans are the cause of global warming. With all the talk about green house gases going up and the amount of emissions that humans are putting into the atmosphere, not very many people talk about the other side of the story. By proving that humans are not the Cause of Global warming people will better understand what really is causing global warming. There are three very important points that one needs to look at when discussing the issue of global warming. One is CO2 concentrations are not very high at all. The second is that solar cycles cause heating on not only earth but other planets. The last would be that global warming of the earth is a natural cycle that the earth goes through and has been going through for many years.

It is very easy to get caught up in the global warming talk. One of the biggest issues is that of carbon dioxide. People claim that carbon dioxide is the main cause of global warming, but carbon dioxide concentrations are not all that high. People have studied that historically there has been much more carbon dioxide in our atmosphere than there is today for example: During the Jurassic Period, 200 million years ago, average CO2 concentrations were about 1800 ppm or about 4.7 times higher than today. The highest concentrations of CO2 during all of the Paleozoic Era occurred during the Cambrian Period, nearly 7000 ppm -- about 18 times higher than today (Global Warming- Introduction). The Carboniferous Period and the Ordovician Period were the only geological periods during the Paleozoic Era when global temperatures were as low as they are today (Global Warming- Introduction). To the concern of global warming proponents, the Late Ordovician Period was also an Ice Age while at the same time CO2 concentrations then were nearly 12 times higher than today-- 4400 ppm. According to greenhouse theory, Earth should have been exceedingly hot. Instead, global temperatures were no warmer than today. With these facts there has to be other factors besides atmospheric carbon influencing earth’s temperatures and global warming. Plus Carbon dioxide is such a small component of Earth's atmosphere that it is only about 0.04% of all gasses in the atmosphere. In the last 600 million years of Earth's history only the Carboniferous Period and our present age, the Quaternary Period, have witnessed CO2 levels less than 400 ppm (Global Warming- Introduction). Scientists fight back saying that the increase in fossil fuels burning are causing the increase in temperature. Human’s use of fossil fuels is just a small portion of the carbon dioxide that makes up our atmosphere. Carbon Dioxide from all coal burning worldwide comprises only 0.013% of the greenhouse gases in Earth's atmosphere (Global Warming- Introduction). This is a very small portion of the Carbon Dioxide that humans contribute to the atmosphere, but what is the percentage of Carbon dioxide contributed by humans to the atmosphere? According to carbon dioxide by human activity is just a minuscule .117% of the entire atmosphere. There are far too many facts stating that carbon dioxide makes up just a little portion of the atmosphere. With humans only contributing only .117% carbon dioxide in the entire atmosphere, humans cannot possibly be the cause of global warming.

Solar Cycles show proof that humans are not the cause of global warming. Scientists have been observing warming on other planets not just earth. Planetary warming was observed on Mars, Jupiter, Pluto, and Neptune’s largest moon Triton during decades following the peak of the Solar “Grand Maximum” (Solar & Climate). These same observations are being made on Earth. Having this information how can scientists say that humans are causing global warming when other planets are experiencing the same warming, and humans are not there? According to Nick Fiorenza on Pluto is...
