Global Warming Is Not Caused by Humans

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 Geocraft.com 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 lunnarplanner.com Pluto is moving further from the sun in its orbit, thus it should be cooling, but instead it is warming. This is one sign that shows that the climate change on Earth is caused by solar cycles. According to Fiorenza the sun is now changing from its solar Grand Maximum to its solar Grand Minimum. The Earth Heats up after every Grand Maximum lagging a bit after the peak (Solar&Climate). Latest science reveals sharp increases in global warming precede sharp increases in carbon dioxide, not the other way around. Global warming causes more carbon dioxide to be released from the oceans (Solar&Climate). Current research shows Earth’s oceans are now beginning to cool (Solar&Climate). Fiorenza says it is also now clear that temperatures over the last century correlate far better with cycles in oceans than they do with carbon dioxide; and the temperature cycles in the oceans are caused by cycles of the sun (Solar&Climate). In 2005 data from NASA’s Mars Global Surveyor and Odyssey Missions revealed Global Surveyor and Odyssey missions revealed that the carbon dioxide “ice Caps” near Mars’s South pole had been diminishing for three summers in a row (National Geographic). Habiullo Abdussamatov head of space research at St. Petersburg’s Pulkovo Astronomical Observatory in Russia, says the Mars data is evidence that the current global warming on Earth is being caused by changes in the sun. “The long-term increase in solar irradiance is heating both Earth and Mars,” he said (National Geographic). Abdussamatov believes that changes in the sun’s heat output can account for almost all the climate changes scientists have seen on both planets. Mars and Earth for instance, have experienced periodic ice ages throughout their histories (National Geographic). Abdussmatov says that man-made greenhouse warming has made a small contribution to the warming seen on Early in recent years, but it cannot compete with the increase in solar irradiance (National Geographic). Abdussmatovs research proves that humans are not the cause of global warming.
Science Daily shows A study in the July 2002 issue of Journal of Geophysical Research-Space Physics, published by the American Geophysical Union, proposes for the first time that interstellar cosmic rays could be the missing link between the discordant temperatures observed during the last two decades (since recorded satellite records began in 1979). The report, by Fangqun Yu of the State University of New York-Albany, proposes that the rays, tiny charged particles that bombard all planets with varying frequency depending on solar wind intensity, may have height-dependent effects on our planet 's cloudiness (Science Daily). "A systematic change in global cloud cover will change the atmospheric heating profile," Yu said. "In other words, the cosmic ray-induced global cloud changes could be the long-sought mechanism connecting solar and climate variability” (Science Daily). With this discovery scientists are closer to proving that humans are not the cause of global warming.
Global warming is a cycle the earth has been going through for many years. There are natural cycles, over which we have no control, that dictate how warm the planet is (BBCnews). According to research conducted by professor Don Easterbrook from Western Washington University last November, the oceans and global temperatures are correlated. The Oceans have a cycle in which they warm and cool cyclically (BBCnews). One of the cycles scientists have named the Pacific Decadal Oscillation (PDO). In April 2008, scientists at NASA’s Jet Propulsion Laboratory announced that while the La Niña was weakening, the Pacific Decadal Oscillation—a larger-scale, slower-cycling ocean pattern—had shifted to its cool phase (NASA: PDO). The picture to the right shows both the La Nina anomaly and the PDO anomaly on a thermal map. For much of the 1980s and 1990s it was a positive cycle which means warmer than average. Observations have revealed that global temperatures were warm too (BBCnews). Scientists say that the oceans control a big part of the temperature and climate of every place in the world. So this shows that humans are not the cause of global warming and that it is a cycle that the oceans go through periodically through time. Professor Easter brook says that the PDO cool mode has replaced the warm mode in the Pacific Ocean, virtually assuring us thirty years of global cooling (BBCnews). The shift in the PDO can have significant implications for global climate, affecting Pacific and Atlantic hurricane activity, droughts and flooding around the Pacific basin, the productivity of marine ecosystems, and global land temperature patterns (NASA: PDO).
Scientists have shown that carbon dioxide levels are not very high at all compared to the past, they have shown that solar cycles are causing changes on other planets, and they have shown that global warming is a natural cycle the earth is going through by showing the ocean cycles. This is clear evidence that humans are not the cause of global warming.
