Tuesday the National Center for Science Education, a nonpartisan group of scientists that works to promote the instruction of evolution in American public schools, announced a new initiative aimed at teaching climate science. The NCSE claims global warming and climate change have become increasingly charged topics in classrooms around the country. The initiative is a way for teachers to be supported in states like Texas, Louisiana, Tennessee, and Oklahoma where regulations are being considered that would require educators to justify the denial of global warming as a valid scientific position. Susan Buhr is director of the Education Outreach Group at the Cooperative Institution for Research in Environmental Sciences at the University of Colorado at Boulder.
