It may be just in time: Only 1 in 5 students says they understand climate change from what they've learned in school, according to an interview on NPR with Mark McCaffrey of the National Center for Science Education. Sometimes this is a result of students--or their school's curriculum--skipping Earth science in favor of biology, chemistry and physics. And sometimes this is the result of confusing lessons that try to teach both sides of the controversy. The problem is that there are not two sides. The scientific evidence is crystal clear. Climate change is real, it's happening now, and since kids in school today will eventually be adults who have to deal with it, they ought to learn about it.
