Politically, environmentalism has had a few good months in the United States. Hurricane Sandy put the words “climate change” back in the national vocabulary. Republican attempts to attack Democrats for waging a “war on coal” failed to win many votes in states like Virginia and Ohio on Election Day. In his second inaugural address, President Barack Obama made climate action a priority. A climate rally in Washington is being planned for later this month, and the president has committed to conducting a “national conversation” on the subject.
