Mankind Is the Main Cause of Global Warming

I would first like to apologize for not posting any graphs; my computer's internet is down and I am writing this from my 4G iPad. I will point out the graphs with their respective sources at the appropriate times. Now on to my arguments: I. Various Universal Causes I. i. Cosmic Rays I. i. a. Position Every approximately 135 million years, Earth enters a more populated area of the Milky Way, and as a result, more cosmic rays hit the Earth, which causes cooling. Currently, we are in a less populated area of the Milky Way, which means that less of these cosmic rays will be hitting the Earth, which means less cloud formation, and of course, warming. [1] for the source on this hypothesis. I. i. b The Sun The sun can also cause it: "The implications, if true, had potentially enormous implications for the debate about natural causes of warming. When the sun is very active, it can be thought of as pushing away cosmic rays from the Earth, reducing their incidence. When the sun is less active, we see more cosmic rays. This is fairly well understood. But if Svensmark was correct, it would mean that periods of high solar output should coincide with reduced cloud formation (due to reduced cosmic race incidence), which in turn would have a warming effect on the Earth, since less sunlight would be reflected back into space before hitting the Earth. Here was a theory, then, that would increase the theoretical impact on climate of an active sun, and better explain why solar irradiance changes might be underestimating the effect of solar output changes on climate and temperatures. "[2] "Since he first suggested his hypothesis over a decade and a half ago, Svensmark and other researchers have slowly been putting together research to test it. " The results were: "Scientists found that when shielding was removed and natural cosmic rays allowed to hit the chamber, cloud seeding increased dramatically, and it increased substantially again when additional artificial cosmic rays were added. Svensmark appears to have gotten it right. "[3] Proof here is in the next sub-sub point. I. i. c. The Sun: part II The sun's cycles have a lot to do with temperatures also. "In this chamber, 63 CERN scientists from 17 European and American institutes have done what global warming doomsayers said could never be done — demonstrate that cosmic rays promote the formation of molecules that in Earth's atmosphere can grow and seed clouds, the cloudier and thus cooler it will be. Because the sun's magnetic field controls how many cosmic rays reach Earth's atmosphere (the stronger the sun's magnetic field, the more it shields Earth from incoming cosmic rays from space), the sun determines the temperature on Earth. "[4] "Svensmark matched the data on cosmic rays from the neutron monitor in Climax, Colorado, with the satellite measurements of solar irradiance from 1970 to 1990. Over the period between 1975 and 1989, he found cosmic rays decreased by 1.2 percent annually, amplifying the sun's change in irradiance about four-fold"[5] So, as the sun's activity increases, so does the temperature. Graph 1: View the Correlation between Solar Activity and Temperature in Source 6. This graph clearly shows that temperature goes up and down with solar activity, because an increase in solar activity directly correlates with an increase in average temperature 1-2 years later. I. ii. Rest of the Solar System The Sun clearly is in a warmer phase, because all of the other planets have increasing temperatures as well. "In 2005 data from NASA's Mars 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. Habibullo 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. "[7] "'Global warming on Neptune's moon Triton as well as Jupiter and Pluto, and now Mars has some [scientists] scratching their heads over what could possibly be in common with the warming of all these planets … Could there be something in common with all the planets in our solar system that might cause them all to warm at the same time? '"[8] Two things can be drawn from this. One, that if other planets are warming, that it is only natural for the Earth to be warming as well. And second, that even if all these planets did have natural causes, then that is a sign of Earth's natural climatic change, instead of man-made. II. Earthly Causes II. i. Ocean Currents Ocean temperature anomalies seem to be rising-along with the temperature. ". .. one can model past temperatures as a linear trend (that started well before CO2 was added in any substantial quantity) and periodic bumps. .. . .. temperatures over the last 100+ years look a lot like a linear trend plus ocean cycle-driven bumps"[2] What is causing all the bumps? : Graph 2: Omitted: The Pacific Decadal Oscillation Has an Enormous Effect on Tempetature in Source 2 II. ii. The 1500-Year Cycle This has to do with a cycle of the climate that can explain the warming. "Through at least the last million years, a moderate 1500-year warm-cold cycle has been superimposed over the longer, stronger Ice Ages and warm interglacials. "[5] Graph 3: 1500-Year Cycle in Source 11 There are two things we can conclude from this graph. First, that up-and-down cycles are normal for the long-term climate. This century's global warming is nothing new. The second thing we can conclude, is that today's global warming is not as bad as the Medieval Warm Period's peak yet, and the Medieval Warm Period was less than the Holocene Maximum Period. "Even more important, the earth is not "the warmest it has ever been. " In fact, the earth was much warmer during the Medieval Warm Period when human agriculture flourished! "[9] "The scientists found evidence that on average, every 1,470 years, plus or minus 500 years, cold, ice-bearing waters, which today circulate around southern Greenland, pushed as far south as Great Britain. "[10] There seems to be a full cycle of up-down-up temperatures of the climate every 1470 years. And this goes as far back as at least 1 million years ago. Currently, we are in an upswing of temperatures, just coming off of the Little Ice Age, the peak to be in a few hundred years, making the peak-to-peak difference between today's global warming and the Medieval Warm Period a little less than 1500 years. So today's Global Warming is a natural, cyclical occurence. Conclusion: And as a final side note, I would like to present this graph that helps disprove the anthropogenic cause theory, regarding again, ocean temperature anomalies: Graph 4: Two 51-Year Periods: Which Is Man and Which Is Mother Nature?
