Climate Change is man caused
Thank you for clarifying on that. I think you were hoping to win the debate just on that title, which in itself speaks indefinitely. I have to clarify some things, because I don"t think we have a debate here. First, the title is plain wrong. Climate change happens regardless of human activity. It "can be explained by natural causes, such as changes in solar energy, volcanic eruptions, and natural changes in greenhouse gas (GHG) concentrations." (the same EPA source as my opponent). The last time CO2 levels were as high as today, it was around 15 million years ago. During that time, species still thrived. Second, burning fossil fuels is the most cost-effective, and the least damaging. Yes, I said least damaging. I won"t get into how because that is not the subject of our debate. Here are just a few: [2] http://news.nationalgeographic.com... [3] http://www.newscientist.com... Long gone is the time when most scientists scratched their heads about ice caps melting. Yes, 2014 is the hottest year. Yes, I have to clarify some things, because I don"t think we have a debate here. First, the title is plain wrong. Climate change happens regardless of human activity.

Yes, 2014 is the hottest year. Yes, climate change is happening. But at the same time, we are putting planks for a global cooling, in a sense. As of right now, I can safely say we are utilizing more renewable energy than at any other time in our existence. As for my opponents sources, I don"t see any of them mentioning that. I"m sorry, but the subject of your sources (yubanet, epa, time, scientific american) either state what global warming is, or are in redundant in stating "2014 is the hottest year". None of them are the subject of human activity causing global warming. If you still insist of debating the topic, I would be glad to, although as I"ve mentioned, there really is no debate.
