*Looks up definition of "Anthropogenic"*
1. I think it's likely we've at least contributed to it. So, yes.
2. I read a New Scientist article about it. They seem like a reliable source (they do have the scientist in their name). Other than that, not much. I'm hoping some people post some more information in this topic.
3. I hadn't heard of it before reading this topic. After a quick wikipedia search, I think Anthropogenic Global Warming is an important issue and requires some big name looking into. It says they don't do their own research though, so it seems more like a group of people just sharing their opinions.
4. I think a lot of people who believe in Anthropogenic Global Warming, like me, don't know that much about the issue, and are basing their opinions on big headlines they saw and not on research and facts. Obviously not all supporters are in this catagory, but I think most (or at least many) are.
5. The New Scientist article I read.
