President Obama pledged to push for action on climate change in his inaugural address, but a poll released Tuesday shows the country remains split over the occurrence and causes of global warming.
According to the CNN-ORC poll, 49 percent said global warming has been scientifically proven to be the result of man-made emissions. That's a strong plurality, but down from 56 percent in 2007.
In addition, 25 percent deny that global warming exists at all, and 24 percent say the climate is changing but not because of man-made emissions.
The responses largely split along partisan lines, with 66 percent of Democrats saying global warming is man-made, 48 percent of independent voters saying the same, and 28 percent of Republicans agreeing.
