References to climate change are going to become something like an index fossil for papers written in the current decade. A paper might seem to have no connection to climate science at all, but if the authors can grasp for some tenuous link that lets them put "climate change" in their abstract, they will. Say you're a researcher fifty years in the future who is doing a literature review. When a paper about anti-hydrogen trapping works in a reference to climate change, you won't even need to look at the date of the paper to know, roughly, when it was written.
