We currently have tags global-warming (6 questions) and climate-change (6 questions). I don't think we need both of these tags, so the question becomes which tag do we keep? I definitely feel one of these should be synonymized to the other and currently favor climate-change as the master tag.
Do you agree that we only need one of these tags? If so, which one should be the master tag?
I've made the answers CW, so feel free to add commentary to your choice if you desire.
