Environmental Protection Agency (EPA)The EPA describes its mission as protecting “human health and the environment.” To that end, it develops and enforces regulations (“When Congress writes an environmental law, we implement it by writing regulations”), gives grants “to state environmental programs, non-profits, educational institutions, and others,” studies environmental issues, sponsors partnerships, teaches people about the environment, and publishes information related to its mission. This link points directly to an EPA page about climate change which includes information both about causes of and the future of climate change, scientific evidence of climate change, and information about steps that could mitigate the consequences of climate change.
