Battle over climate science now spreads to US schoolrooms

摘要

Schools in three US states -Louisiana, Texas and South Dakota -have been told to teach alternatives to the scientific consensus on global warming. The moves appearto be allied to efforts to teach creationism in public schools. Such efforts have in the past been thwarted when courts ruled them unconstitutional, but those advocating the teaching of sound science may find it harder to fight misrepresentations concerning climate change.
