Mankind Is the Main Cause of Global Warming

I apologize, my computer's internet is still down, so I cannot post graphs, I will just have to post the links. And also, Graph 3 from my Round 2 is in Source 9, not the non-existant source 11. Sorry for the confusion. Defending My Arguments I. i. I am going to leave the sun refutation to I. ii. , but my original argument here has not been responded to. I. ii. First, higher sun activity causes fewer cosmic rays to hit the earth, not the other way around. This can be seen in the graph below: Graph 1: Cosmic Rays - The Evidence. Source 1. The graph also shows thst cosmic rays do have an effect on cloud formation. "With the new results just published in the recognised journal Geophysical Research Letters, scientists have succeeded for the first time in directly observing that the electrically charged particles coming from space and hitting the atmosphere at high speed contribute to creating the aerosols that are the prerequisites for cloud formation. "[2] So yes, there is direct proof. Finally, here is a picture showing the process: Graph 2: Cosmic Rays's Affect on Cloud Formation. Source 2. Also, I said last round, " 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. " So yes, I have shown that it is something that is happening at the very moment. My opponent has claimed that I haven't provided any evidence, but in this and the last round, I have. I. i. c. I have proved, in my previous round points and in the point above this, that cosmic rays one, correlate inversely with solar radiation and correlate directly with cloud formation. ". .. natural cosmic rays allowed to hit the chamber, cloud seeding increased dramatically. .. "[3] I have given substantial evidence. I. ii. ". .. it was noted the planet [Mars] was experiencing rapid warming, similar to what the Earth is currently undergoing. .. . The Martian icecaps are melting at a perilous pace. .. . . .. and that both [warmings on Earth and Mars] can be explained by changes in solar irradiance. "[4] "Global warming was detected on Jupiter last year, and the warming is apparently behind the formation of a second red spot. Global warming on Neptune's moon Triton has also been noted, with severe atmospheric changes as a result. And even tiny Pluto has experienced moderate warming in recent years, with temperatures rising a full 3.5 degrees. The common denominator in all these cases, the Earth included, is of course the Sun, which is in the middle of an extremely active period at present. "[4] "It looks as though the atmosphere has not changed from 2002, which is pretty surprising because we expected the atmosphere would freeze out as the planet moved further away from the Sun," he said. "But so far, if anything, the atmosphere has gotten even denser. "[5] So yes, all of these bodies are indeed warming, and it can all be attributed to increases in solar irradiance. II. i. My opponent drops my argument here. I will cover his original contentions later. II. ii. Graph 3: 1500-Year Cycle in Blue. Source 6. So indeed, the Medieval Warm Period and the Holocene Climate Maximum were higher than today. And, there is ample evidence that the Medieval Warm Period and Holocene Climate Maximum were hotter than today: "Chinese temperatures were 2 to 3 degrees C higher than present during China's climate optimum based on pollen data and the souther limits of permafrost. " "The Mediterranean region, including the coast of North Africa, got more rainfall during the Medieval Warming period than it does in our time. " ". .. during the Medieval Warming. .. . Temperatures may have been as much as 2.5 degrees C warmer [than today] due to a southward shift of the climate belts. " ". .. the central Argentinean area had more precipitation during the Medieval Warming than today. Temperatures may have been as much as 2.5 degrees C warmer due to a southward shift of the tropical rainbelts. " "The largest anomaly was a rapid warming-4 degrees C-between 350 B. C and A. D 450, reflectinga warmer climate in equatorial East Africa. Was this the Roman Warming? The Weizmann researchers noted warming during the same period in the Swedish part of Lapland and in the northeastern St. Elias Mountains of Alaska and the Canadian Yukon. " "On Signy Island, halfway between Antarctica and the southern tip of South America, oxygen isotopes preserved in lake sediments provided a 7,000-year climate record. They clearly show the Roman Warming. .. , the Dark Ages [cooling]. .. , the Medieval Warming, the Little Ice Age, and the 20th century warming-which is cooler to date than the Medieval Warming. "[7] Graph 4: South Africa: Makapansgst Valley proxy Temperature reconstruction. Source 7. I will keep coming with more. The Roman Warming, The Medieval Warm Period and the Holocene Climate Maximum were clearly higher in all areas of the world, not just Europe. "Indirect evidence suggests that the average temperature was as much as 1.5 degrees Celsius warmer [during the Medieval Warm Period] than today. "[8] Attacking My Opponent's Arguments I will not refute individual points, but his argument in general. If I skip anything, it will be because I already covered it above. First, 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). "[9] Second, 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. "[9] So, the theory is reversed. CO2 does not cause global warming, but vice versa. And finally, the sun correlates better. Graph 5: The Sun Is more Likely the Dominant Driver of the Recorded Arctic Temperature Variations. Source 10. Also, Graph 6: Global Lower Troposphere Temperatures and CO2. Source 11. Conclusion "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.
