CO2 emissions are directly responsible for climate change.

Before I make my points, I would like to address the mistaken Negative. I do know that the topic is "CO2 is the largest factor in global warming", and that is what I am arguing. I'm sorry if that wasn't made clear in my evidence, but if you look back you will find that I certainly did argue that point. Your evidence was arguing against CO2 being the largest factor, and as your opponent that is what I must counter. Now that it's out of the way, let's begin. Negative thinks I only believe CO2 is speeding up the process of climate change. It most definitely is, and they are not mistaken in that. But not only is it speeding up and forcing climate change to continue, it is the main factor in this. No matter what my opponent may think, my evidence clearly showed CO2 is the largest threat. Greenhouse gases are proven to be the largest contributor to global warming, and CO2 is the largest greenhouse gas. And according to the World Meteorological Organization, the US Environmental Protection Agency, NASA, the European Commission and thousands of scientists, CO2 is the largest factor. Negative may say that fluctuations in the earths orbit are the largest cause. To say that fluctuations in earths orbit are the largest cause is a bold statement. I think that by orbit fluctuations, he means that it causes Suns rays to hit the earth more. But according to NASA, solar maxima is only .1 percent higher than solar minima on average. To further my counter argument, if there had been an increase in solar output, both the stratosphere and troposphere would have warmed up. But instead, patterns show that the stratosphere has actually cooled. Meanwhile, land and the troposphere have been warming, which is no doubt due to greenhouse gases (particularly CO2). This shows that fluctuations in earths orbit, although drastically climate changing when they occur, are not occurring right now. However, the effects of the Suns rays on earth are increasing. Not because of orbit fluctuation, but because of greenhouse gases that trap the Suns heat. CO2 is directly responsible for global warming today. In the earlier graph, I showed how carbon emissions have increased drastically since the industrial revolution. I then linked a graph that showed temperature increase over the same time period. The fact is, since the industrial revolution, temperatures have drastically increased at a rate that would never have occurred without coal burning and that whole era. So CO2 emission IS directly responsible for global warming. The negative, in their conclusion, called my points invalid. I say the exact opposite. I stand by my points, and the facts that went with it. I most surely do not agree that their case is correct. I have just shown why their case is completely wrong. CO2 was the initial cause of global warming, and this is shown in hundreds of studies and tests since that show the before and after the industrial revolution. The fact is, today CO2 is the largest factor and the cause, and I have all the sources to support it. Sources: http://earthobservatory.nasa.gov... And sources I cited earlier.
