The American people need to know whether Congress is listening to the overwhelming majority of scientists when it comes to climate change.

On this issue, the scientists have been virtually unanimous in saying that climate change is real, it is caused by human activity, that it is already causing devastating problems in the United States and around the world and that it is imperative that we  transform our energy system away from fossil fuel.

Do members of Congress believe the scientists or not?
