My question Evidence indicating that CO2 is responsible for Global warming was closed as being too broad.
There are many research papers on the topic, however it is a very specific question. If you are willing to suggest edits to re-open this question, I would be willing to listen, but I don't understand why it must be closed. Have I violated a policy?
I hate the fact I have to talk about policy now. But if this question is closed even questions such as "What evidence do we have that GR(insert any theory) is correct?" must also be closed. It is outrageous to me, but it's your site.
