| | Re: Is Human Activity Responsible For Increased Global Warming? [Science Coursework]?
Well, it is very likely that humans are causing or contributing to the current global warming. The research exists on both sides, although those against are grossly outnumbered, and often-very unscientific. There are litterally thousands of places you could go for references, try NASA's website for some links and further reading, and I'm not sure where you'd find legitimate against positions, but there must be some.
