Resolved: That Global Warming is a manmade problem.

I also ask that the voters vote based on who made the better arguments despite your personal opinion. With that said, these are my reasons why global warming IS a manmade problem. Contention 1: CO2. Over the last 100 years, we have used more fossil fuels that at any point in the history of the earth. These fuels include coal, oil, and natural gas. Scientists say this has a major effect on the earth's temperature because of CO2 emissions from burning said fuels. This graph shows the relation between fossil fuels and CO2 emissions. (. http://zfacts.com...) We can also look to how CO2 affects the climate. If you look at these: (. http://www.seed.slb.com...) and (. http://www.solcomhouse.com...), you can see how global temperature is right in-line with CO2 levels. This is because the greenhouse effect traps CO2 in the atmosphere. Carbon Dioxide levels have increased 34% from the pre-industrial era. Thus, we can see that the rise in CO2 levels and the rise in global temperature is no coincidence. Lastly, if you look at this graph (. http://upload.wikimedia.org...), you can see that CO2 emissions don't look like they are going to go down anytime soon. Thus, we can expect a drastic CO2 spike in coming years. This graph also disproves the ‘natural cycle' argument. Contention 2: Temperatures. There is empirical evidence of global warming. If you look here (. http://en.wikipedia.org...), you can see that every one of the last 14 years (1994-2007) is one of the warmest 20 on record. Also, the ten hottest years on record all occurred within the last 14 years. According to NASA scientists here: (. http://climateprogress.org...), 2007 was the second warmest year EVER. There is expected to be record warmths by 2010. We can clearly see this is no coincidence of man's record use of fossil fuels and the record of hottest temperatures. Third and finally, ocean temperatures show a correlation between man and global warming. From this source, (. http://www.commondreams.org...), scientists found that this could be nothing but man-made. They said this: "Dr Barnett said: "Over the past 40 years there has been considerable warming of the planetary system and approximately 90 per cent of that warming has gone directly into the oceans. " "He told the American Association for the Advancement of Science in Washington: "We defined a 'fingerprint' of ocean warming. Each of the oceans warmed differently at different depths and constitutes a fingerprint which you can look for. We had several computer simulations, for instance one for natural variability: could the climate system just do this on its own? The answer was no. " All in all, temperatures show that global climate change is indeed man-made. Contention 3: Scientific opinion. Most scientists agree that global warming is a man-made problem. I may add that my opponent is not a scientist. Therefore, he does not spend his entire day researching global temperatures like scientists do. We must trust them more than CON. Here is a study: (. http://www.sciencemag.org...) It stated: "A 2004 survey by Naomi Oreskes of 928 peer-reviewed scientific articles on global climate change published between 1993 and 2003. The survey, published as an editorial in the journal Science, found that every article either supported the human-caused global warming consensus or did not comment on it. " 175 countries have ratified the Kyoto Protocol, which strives to reduce greenhouse gas emissions. The U. S. has not. Just look at all of these statements by scientific groups. EVERY ONE admits global warming is man-made. I now await my opponent's round 2 rebuttal.
