Mankind Is the Main Cause of Global Warming

Observations Ob1: Under “Full Resolution”, it clearly says the existence of GW is assumed, and Con must show that it is not man-made. This is violated by Con, but I shall rebut it nonetheless. Ob2: Once more, Con’s entire case is C/P’d from his source (albeit the source is presented this time), thus there are no original arguments presented by Con. Ob3: Con violates the debate structure by dropping ALL my arguments. I extend all my arguments to this round. Rebuttals R1) Global Warming Exists According to NASA’s GISS surface temperature analysis, the global mean land-sea temperature rose from 1980 to 2014 by 0.8 degrees Celsius, and the corresponding graph shows a constant increase in temperature throughout the years from 1980 to 2014 [1]. The alleged 17-year pause is incorrect, as there has been a 0.8 degrees C increase in temperature. The global land-sea average temperature in December 2014 was the highest monthly land-sea average in 135 years [2]. There have been major temperature anomalies throughout December 2014 itself [3]. R2) Scientific Consensus A study published in Science reviewed the ISI web of science in order to take a survey of relevant climate literature as to what the causes of climate change are. The study failed to find a single paper which was in opposition to the consensus position, that the main driver of climate change is anthropogenic. 75% of the papers supported the consensus position, whereas 25% had no position (they were focused on things other than forgings, like impacts or paleoclimate) [4]. “[T]he National Academy of Sciences report, Climate Change Science: An Analysis of Some Key Questions, begins: “Greenhouse gases are accumulating in Earth's atmosphere as a result of human activities, causing surface air temperatures and subsurface ocean temperatures to rise.” [4-5] A 196 page report representing 13 governmental agencies, and written by 28 authors from scientific institutions, has stated “[t]he global warming of the past 50 years is due primarily to human-induced increases in heat-trapping gases …” [6] According to NASA, “[n]inety-seven percent of climate scientists agree that climate-warming trends over the past century are very likely due to human activities.” [7] Above is a graph presented by 4 major institutes that have taken a study on the temperature anomaly, and the results from NASA, MOHC/CRU, NOAA Climatic Data Center, and the Japanese Meteorological Agency have almost identical results [7]. R3) Arctic Ice Con concedes that this is irrelevant to the issue, and this is merely a prediction made by some supporters of global warming, thus I need not address this. Nonetheless, I wish to point out that “[t]he European Space Agency’s CryoSat mission has returned its latest map of Arctic sea ice volumes, recording a slight decrease in thickness over previous measurements.” [8] R4) Climate Models While climate models may have been wrong, they were only predictions of the increase. A certain level of increase happened nonetheless, and that is relevant to the resolution, while this is completely irrelevant to the resolution. R5) Predictions This is a repeat of “Climate Models” and “Arctic Ice”. The current data is not faulty unless proven otherwise, thus this argument is useless and irrelevant. I sincerely request Con to frame his own argument for the next round instead of C/Ping it. Arguments ALL my arguments are dropped. I extend all my arguments.
