Anthropogenic global climate change.

Round two argumentsOutline.I. Scientific consensus.II. Co2 is the main driver.III. The Co2 is from humans in lieu of natural.IV. Other supporting evidenceV. SourcesI. Scientific consensus.Claim: A scientific consensus exists for anthropogenic climate change existence. Warrant:"Multiple studies published in peer-reviewed scientific journals1 show that 97 percent or more of actively publishing climate scientists agree: Climate-warming trends over the past century are extremely likely due to human activities. In addition, most of the leading scientific organizations worldwide have issued public statements endorsing this position. The following is a partial list of these organizations, along with links to their published statements and a selection of related resources." [0]Impact: A scientific consensus is an agreement upon experts in the field. Think of one hundred heart surgeons agreeing upon a heart surgery technique. Heart surgeons would have more credibility than brain surgeons, dentists, and dermatologist. Even though all four are doctors, only the heart surgeons are most qualified on the subject of heart surgery. The same is true for climate scientists. A geologist, a physicist, and a biologist are all scientists. Yet, only climate scientists are the top notch for qualifications. These are the experts of experts in the field of climate science. There is nobody more qualified then this group of people. The fact that they came to a consensus based upon multiple lines of empirical evidence, used social calibration to determine what qualified as evidence, and social diversity, from many different parts of the world gives an enormous impact. The reason why social diversity is important is to avoid groupthink which can taint the consensus. "What Is Groupthink?Groupthink occurs when a group values harmony and coherance over accurate analysis and critical evaluation. It causes individual members of the group to unquestioningly follow the word of the leader and it strongly discourages any disagreement with the concensus. " [1]Here is the peer reviewed sources that confirm the scientific consensus. "J. Cook, et al, "Quantifying the consensus on anthropogenic global warming in the scientific literature," Environmental Research Letters Vol. 8 No. 2, (15 May 2013); DOI:10.1088/1748-9326/8/2/024024Quotation from page 3: "Among abstracts that expressed a position on AGW, 97.1% endorsed the scientific consensus. Among scientists who expressed a position on AGW in their abstract, 98.4% endorsed the consensus.”W. R. L. Anderegg, “Expert Credibility in Climate Change,” Proceedings of the National Academy of Sciences Vol. 107 No. 27, 12107-12109 (21 June 2010); DOI: 10.1073/pnas.1003187107.P. T. Doran & M. K. Zimmerman, "Examining the Scientific Consensus on Climate Change," Eos Transactions American Geophysical Union Vol. 90 Issue 3 (2009), 22; DOI: 10.1029/2009EO030002.N. Oreskes, “Beyond the Ivory Tower: The Scientific Consensus on Climate Change,” Science Vol. 306 no. 5702, p. 1686 (3 December 2004); DOI: 10.1126/science.1103618." [0]II. Co2 is the main driver.Claim: Co2 matter because the gas absorbs infrared radiation. Warrant:"Molecules of carbon dioxide (CO2) can absorb energy from infrared (IR) radiation. This animation shows a molecule of CO2 absorbing an incoming infrared photon (yellow arrows). The energy from the photon causes the CO2 molecule to vibrate. Shortly thereafter, the molecule gives up this extra energy by emitting another infrared photon. Once the extra energy has been removed by the emitted photon, the carbon dioxide stops vibrating." [2]Impact: Co2 absorbing infrared radiation plays a crucial part in the greenhouse gas rising of Earth's temperature. Claim: Co2 makes up 81% of the greenhouse gases.Warrant: [3] Pie graph should display here. Impact: This shows that Co2 is the main driver of climate change. III. The Co2 is from humans in lieu of natural. Claim: We know the Co2 is from humans due to human finger prints. Warrant: [4] Impact: These show that the Co2 is human caused as opposed to natural. IV. Other supporting evidenceThere is other supporting evidence, the over 400 ppm of Co2, sea level rise, global temperature rise which is now at 1.7 degree Fahrenheit, warming oceans, shrinking ice sheets, and many more. These all reinforce that anthropogenic climate change is happening. [5]V.
