High school and middle school teachers might not know the best way to teach their students about global warming, according to the National Center for Scientific Education.

Class discussion: What do the vast majority of climate scientists agree is the likely cause of the change? What effects of climate change are already observable? How much has the world's average temperature risen since the beginning of the industrial revolution? How much is the global temperature expected to rise this century? What do your teachers tell you about the issue?
