"President Obama plans to announce three cabinet-level nominations Monday, including a new administrator for the Environmental Protection Agency, who could be on the hotseat in the looming battle over global warming."

"Gina McCarthy, currently an assistant administrator in the wing of the EPA that regulates air pollution, is the president's pick to head the EPA.

Obama will also tap the director of MIT's Energy Initiative, Ernest Moniz, as his new energy secretary, and the president of the Walmart Foundation, Sylvia Matthews Burwell, to head the Office of Management and Budget.

The nominations will be announced at the White House Monday morning. All three require Senate confirmation."
