Mankind Is the Main Cause of Global Warming

I. Find the Gases that Causes the Planet to Warm My opponent here is just presenting the different gases. This is an observation, not an argument. We will differ when anthropogenic arguments are presented. II. Ensure that those Gases Enter and Remain in the Atmosphere in Greater (or Lesser) Quantities than BeforeII. i. Methane Human contribution to methane concentrations is actually rather small: [1]And even if human causation was the main factor of methane concentrations, the amount of methane increase has actually been decreasing, and is now decreasing: [2]Notice that during the infamous "hockey stick" (I will get to that later) times, methane increases were actually decreasing. So, not only are humans relatively small causes of methane concentrations, but methane amounts are actaully decreasing at this point. II. ii. CFCs Even though CFCs are mostly man-made in origin, there concentrations have been decreasing also: [3]Again, just like methane amounts, during the main warming times, CFCs concentration increases were decreasing, and are now negative. II. iii. Nitrous Oxide As with methane, human contributions to nitrous oxide are very small: [1]In fact, ocean amoeba are a major cause of nitrous oxide: "Dr Trimmer looked at nitrous oxide production in the Arabian Sea, which accounts for up to 18 % of global ocean emissions. He found that the gas is primarily produced by bacteria trying to make nitrogen gas. "[4] And that is just the Arabian Sea. And even if cows did cause a lot of warming: ". .. a new study found that cattle grazed on the grasslands of China actually reduce another greenhouse gas, nitrous oxide. "[5] So, humans are positive in this aspect. II. iv. Carbon DioxideThis will be my main point. First, by the greenhouse effect, global warming should be starting from the lower atmosphere and moving to the surface, but this is not happening: ". .. satellite and high-altitude balloon data confirm that the lower atmosphere is not trapping lots of additional heat due to higher CO2 concentrations. It is hard to know how fast the Earth's highly variable surface is warming, but it is warming faster than the lower atmosphere where the CO2 is accumulating. This is strong evidence that CO2 is not the primary climate factor. "[6]Here is a graph relating to the point, showing the decrease in upper troposphere temperature anomalies, disproving the greenhouse theory here: [7]Second, CO2 levels do not correlate with temperature very well: "In the last decade, there has been no clear warming trend (as the UK Met Office and IPCC’s own figures demonstrate). In the last century, much of the warming occurred prior to 1940, when human emissions of CO2 were relatively small compared to today. During the post-war economic boom (when one would have expected the temperature to rise) the world cooled, from the 1940s till the mid-70s (again, this is evident from accepted data used by the IPCC). "[8]Here is a graph showing the fallacy of the CO2-temperature correlation: [9]As shown, CO2 does not correlate with temperature. This next graph compares solar activity and CO2 to temperature. It is easy to see which one correlates with temperature more: [10] Third, global warming is not starting at the poles like it should be, by the greenhouse theory. In fact, there has been general, relative cooling: "If the greenhouse thoery were valid, temperatures in the Arctic and the Antarctic would have risen several degrees Celsius since 1940 due to the huge emissions of man-made CO2. .. Recently, a team led by the University of Chicago's Peter Doran published a paper in Nature saying, 'Although previous reports suggest recent continental warming, our spatial analysis of Antarctic meteorological data demonstrates a net cooling on the Antarctic continent between 1966 and 2000'. The data from 21 Antarctic surface stations show an average continental decline of 0.008 degrees C from 1978 to 1998, and the infrared data from satellites operating since 1979 show a decline of 0.42 degrees C per decade. David W. J. Thompson of Colorado State University and Susan Soloman of the National Oceanographic and Atmospheric Administration also report a cooling trend in the Antarctic interior. . .. report that satellite imaging shows increases in Souther Ocean sea ice parameters from 1978 to 1996 and an increase in the length of the sea-ice season in the 1990s"[6]"Greenland has also been growing colder over the last half-century. .. "". .. examined the temperatures for the entire Arctic for 1951 to 1990, he [Rajmund Przybylak, Polish climatologist] reported, 'no tangible manifestations of the greenhouse effect [could] be identified"[6] This graph shows the arctic temperatures. The blue line is the melt point. Clearly, it spends little time there: [11]This graph shows that Antarctic sea ice extent is rising: [12] Fourth and finally, CO2 is a lagging indicator: ". .. the CO2 changes have lagged about 800 years behind the temperuatre changes. Global warming has produced more CO2, rather than more CO2 producing global warming. "[6] So, the theory is reversed. CO2 does not cause global warming, but vice versa. II. v. Water Vapor Believe it or not, the four gases mentioned above actually make up about 5% of all greenhouse gases. The other 95% is natural made water vapor: [1]So all of the other gases' contribution to global warming is almost negligible compared to water vapor. II. vi. Conclusion "Just how much of the "Greenhouse Effect" is caused by human activity? It is about 0.28%, if water vapor is taken into account-- about 5.53%, if not. "III. Watch as the Planet Warms or Cools Six Degrees, the Difference between Now and the Last Ice Age "During the last 150 years there has been another fairly sustained period of global warming amounting to an increase of about 0.7 degree Celsius. In spite of rhetoric to the contrary, the majority of this warming took place naturally before 1940. This warming trend was interrupted by a 35-year cooling period from 1940 to 1975. This caused many climatologists to actually predict that we were entering another ice age. At that time the public was obsessed with “global cooling. ” Today, our obsession is “global warming. "[13] Still, today's global warming is nothing new, in fact, it is not even that big: [14]Sources:[1]: . http://geocraft.com...[2]: . http://www.skepticalscience.com...[3]: . http://www.esrl.noaa.gov...[4]: . http://www.sciencedaily.com...[5]: . http://www.telegraph.co.uk...[6]: Singer, S.
