Happy Earth Day! In honor of today, we're looking at climate change from two perspectives.

First, going carbon neutral. According to a recent Pew survey, Americans largely favor taking steps towards becoming carbon neutral. Other polls show a majority of Americans -- in some cases majorities of Democrats and Republicans -- are willing to make sacrifices to address global warming, but a majority also think it may not be enough.

Then, Katherine Hayhoe, Chief Scientist at the Nature Conservancy, as well as Professor of Political Science at Texas Tech, joins us to talk about faith and climate science. As a Christian and a scientist, she has a fascinating perspective on the interconnected nature of faith and climate change. You can find out more about her work here, by following her on Twitter @KHayhoe, or by getting her book “Saving Us: A Climate Scientist’s Case for Hope and Healing in a Divided World.” 

Finally, our fun fact is about another changing climate -- fast food! Why are polls misaligned with sales?
