Global warming is likely (and mostly) anthropogenic

As per the rules, I will wait until my next round to refute Pro’s arguments. Some of my arguments may overlap, but they were written before Pro posted his arguments. 1.) Correlation =/= Causation Proponents of anthropogenic global warming often point to the correlation between CO2 and the rise in global temperatures. According to the Center for the Study of Carbon Dioxide and Global Change, in order to prove a causational relationship, one must prove that the supposed cause preceded the effect. The pseudoscientists who propose CO2 as a cause for global warming fail to address what came first; the rise in CO2 or the rise in temperatures. The Center for the Study of Carbon Dioxide and Global Change has suggested that the rise in temperature precedes the rise in CO2, and therefore the temperature is the cause of the rise in CO2. http://www.co2science.org... 2.) Ocean Temperatures and CO2 Studies have shown that a rise in ocean temperatures lead to a rise in CO2 in the atmosphere. Warmer waters release CO2 while colder waters absorb CO2. As global temperature rises, water temperatures increase, thereby releasing CO2 into the Earth’s atmosphere. According to a study conducted by Lon Hocker; the atmosphere contains 720 billion tons of CO2, while the Earth’s Oceans contain 36 trillion tons. The study found that the oceans are responsible for 0.275 ppm of CO2 for every temperature increase of 1°C. Hocker concludes that the oceanic release of CO2 is responsible for the observed 0.22 ppm increase in CO2 per 1°C temperature increase. http://wattsupwiththat.com... Another recent study conducted by Dr. Jeffrey A. Glassman examined the CO2 -temperature relationship of the last 420 millennia. The study concluded atmospheric CO2 concentrations are an effect of changes in the earth’s temperature, not the cause. The study found that the atmospheric CO2 trends were caused by changes in ocean temperatures, and that, while a greenhouse gas, CO2 has “neither caused nor amplified global temperature increases”. http://www.rocketscientistsjournal.com... 3.) Historical trends Climate has been occurring all throughout Earth’s history; it has been occurring long before the evolution of man, and it will continue long after we are gone. The assumption that man is the reason for climate change is more of a religion than science; only instead of god punishing us, it is assumed that the earth is punishing us. Because weather satellites only existed since the 1960’s and weather balloons only existed since the 1890’s, mapping historical data depends heavily on ice cores, and tree rings. Atmospheric temperature research began near the end of the little ice age; it is assumed that temperatures would increase after a mini ice age. According to ice core research, most of the last 10,000 years were warmer than it is today. The current temperature is considered very low by comparison. Most advocates of manmade global warming only look at the data dating back to the little ice age. This is because the global temperature has increased since the little ice age. If you want to see cooling or warming, it depends on where you start your timeline. http://www.skepticalscience.com... A study of Tree rings was conducted by the Department of Quaternary Paleogeography and Paleoecology at the University of Silesia and the Institute of Geography and Regional Development at the University of Wroclaw. The study mapped over 7,500 years of finish tree ring data, which coincides with the ice core samples. Using the tree ring data, they were able to forecast future trends. They predicted that within the next 40 years there will be a cooling trend, followed by another warming period. Just because the climate is changing, does not make it our fault. The climate has been changing since the earth’s conception. 4.) The real cause of global warming The real cause of global warming is not man, but rather the sun. Increases and decrease in the frequency of sun spots have an impact on global temperatures and of course the climate. The frequency of volcanic activity also has an impact on the climate. Volcanoes shoot ash and CO2 into the air, blotting out the sun, thereby creating a cooling effect. http://blogs.telegraph.co.uk... http://www.youtube.com... http://www.youtube.com... Conclusion Global Warming is not man-made, it is a natural phenomenon. Climate change has been occurring throughout earth’s history.
