Global Warming is man-made

Hello again and welcome back. I thank my opponent for his quick response. I’m sorry for the lousy opening argument. I did it fairly quick on my iPad and hopefully will have better refutations than last time. I wish my opponent the best of luck as we advance further in the debate. I will start by rebutting his rebuttals and work my way backwards. It appears he combined both rebuttals into 1. My opponent states that glaciers melting is proof that global warming exists. But, have glaciers not melted in the past? The melting of glaciers has been present throughout history, due to the natural heating and cooling of the Earth. And, also on that graph, you can see that (excluding the area between about 300,000 and 150,000 years ago, where the tempature stayed fairly similar) the Earth's heating seems to get more intense every time. And, it is likely that we are experiencing a similar pattern. First of all, it should be “Glaciers melting are” and “Temperature.” Just want to help you out there. My opponent contends that it does not prove anything and it just has been a “cycle.” I challenge my opponent to this. Why? He has provided no evidence whatsoever and thus his points are invalid. Even IF that were the case, I shall point out that there is no reason that, in the last decade, the sea level DOUBLED in height from last century. (1) Furthermore, I shall point out that the rate that glaciers are retreating is astounding. The “cycle” theory does not explain why glaciers seem to be retreating everywhere—not just one place. Rebutting my opponent’s points 2) Phil Jones. My opponent has taken his interview out of context. I challenge my opponent to see what he really did say. (2) Phil Jones recently examined the up-to-date data, and has now stated "If you add the value of 0.52 in for 2010 and look at 1995 to 2010 then the warming is statistically significant at the 95% level."(3) My opponent also contends that it was Phil Jones that supplied the data. That is wrong. The hockey stick graph was published by Michael Mann. 3) Consensus Opponent dropped this point. I shall point out that I will never use this argument to support global warming. 1) Hockey stick graph My opponent contends that the hockey stick graph is the major tool to show Global Warming. In fact, it is not even included in the most recent IPCC report, the one issued 4 years ago. If my opponent wishes to argue against the state of science prior to the year ’00, then I am not interested. Even 10 years ago, the graph was NEVER used as proof, but merely as background. The graph my opponent led me to was not the hockey stick graph that is used. The one that is mostly used is found in source 4 My opponent has not given a shed of sources to back up his claims. Lastly, my opponent claims that global warming accounts for abnormally hot winters and summers, but not cold winters. Again, my opponent is wrong and hasn’t even brought sources to prove that. To help him out, I have. In source 5, there is information about how global warming effects cold winters. I eagerly await my opponent’s response and challenge him to bring up sources. If I missed anything, I would request my opponent brings that up so I can touch on it.
