While reiterating that he is a "firm believer" that climate change is real and affected by human behavior, President Obama made clear today that he won't be proposing major new efforts to control U.S. carbon emissions anytime soon. In his first news conference since winning re-election, Obama acknowledged that "we haven't done as much as we need to" to fight global warming, but he also offered few details on how he intended to proceed on the issue beyond what he was able to do in his first term.
