Global warming is one of the world′s most argued topics. The majority of people agree that the global warming is real, but the most controversial aspect is whether it is caused by humans or simply part of a cyclical process of nature.

The argument can aid students understanding of the tension between public policy and rigorous scientific inquiry when decisions could lead to environmental and human harm.
