Actually there is a certain logic to it. If you're an academic "researcher," and want glory and grant money, you put the tag line, climate change, onto your study. For example, Climate change raises foot fungus disease, sells a lot better than "Hot smelly feet have athletes feet." Plus you get swooned over by colleagues and feeble minded college administrator, foundation hustlers, and do-gooder groups on campus. Do otherwise, and you get trampled by the screaming mob.
