With NASA reporting that 2015 is on track to be the hottest year on record for Earth and as parts of the Western United States are gripped by extreme drought, Americans are less likely than at any time since 2008 to say there is not solid evidence of global warming.

This is down from 33% just 18 months ago. CONT.
