Research Papers / Help Starting a Global Warming - Argumentative Research Paper; focus on human responsibility [9]

Ok, so I have to write an argumentative research paper on global warming...My professor suggested I focus on human responsibility. This is because I believe humans are a fairly large factor with green house gasses. It has to be 10 pages long double spaced and argumentative as I said before. I would like to talk a lot about what we can do as humans to help prolong life on Earth...recycling, petroleum free vehicles, avoiding burning fossil fuels...etc...I suppose my main issue at the moment, is coming up with a decent thesis, which can give me a good amount of subtopics to discuss. I've been doing some research on global warming as a whole, and I'm finding that there is just so much information I don't know what to do with it all. Any thesis ideas along what I'm reaching for...and maybe some good topics that might have the right amount of information to be useful?

Thank you for your time,
S
