Watch: Democrats at convention more worried about ‘climate change’ then ISIS
Delegates vote 'climate change' as bigger threat than ISIS.
Woman: "The threat of climate change is a certainty. ISIS isn't coming through the Philadelphia streets, but it has been a squelchingly hot week here."
Man: "Climate change isn't just now. It's not like ISIS is just now. We can deal with them. If we don't deal with climate change the future is at threat too."
