State of the Union 2013 Live: Believe in Science

Climate change is always a hot topic and the president makes it clear that we need to pay attention to the signs that nature is giving us and listen to what science telling us and act now to preserve our planet.

If Congress won't act, the president will instruct his cabinet to "come up with executive actions we can take, now and in the future, to reduce pollution, prepare our communities for the consequences of climate change, and speed the transition to more sustainable sources of energy."
