The Environmental Protection Agency says global warming is one of the most significant public health threats of our time. That's according to EPA Administrator Gina McCarthy. McCarthy is defending a plan to curb carbon pollution in a speech this morning. She says global warming is not just about melting glaciers. The proposal is the first significant step in President Barack Obama's climate plan, but the plan only deals with future power plants. Judith Enck is the EPA Regional Administrator.
