Yale has a nice website where you can view interactive maps on responses to a variety of questions related to the acceptance of climate change. Interestingly, while a majority, including Southerners, seem to accept climate change is real many do not believe it caused by humans or we should support alternative energies.
Public opinion about global warming is an important influence on decision making about policies to reduce global warming or prepare for the impacts, but American opinions vary widely depending on where people live. So why would we rely on just one national number to understand public responses to climate change at the state and local levels?
