The Senate's confirmation of Gina McCarthy as head of the Environmental Protection Agency is a welcome development and a signal that Congress and the President are willing to get serious about the Agency's role in protecting the health of all Americans and the affects of climate change on the environment. It won't be easy. Lawmakers seem divided on nearly every issue in this debate. In the past EPA's efforts to protect the environment and public health and safety have sometimes been delayed by the White House's own Office of Information and Regulatory Affairs (OIRA). Cutting through such bureaucracy should be on the short list of the new administrator's priorities. Climate change knows no political ideology and it follows its own timeline. Administrator McCarthy is well equipped to meet the challenges we face. We are lucky to have her fighting for us all.
