This document evaluates and compares two websites on climate change - one run by the Environmental Protection Agency (EPA) and one run by the activist group Greenpeace. The EPA site is found to be more authoritative and accurate as it is run by a government agency and focuses on factual research. Meanwhile, the Greenpeace site shows some bias as it aims to encourage environmental protection in line with the group's views. Overall, the EPA site is deemed more trustworthy for students due to its reliance on facts over advocacy.
