Very Few Doubt Global Warming

A new Associated Press-GfK poll finds that 78% of Americans now think temperatures are rising and 80% say global warming will be a serious problem for the United States if nothing is done about it.

Key finding: The biggest change in the polling is among people who trust scientists only a little or not at all. Within that highly skeptical group, 61% now say temperatures have been rising over the past 100 years. That’s a substantial increase from 2009, when the poll found that only 47% of those with little or no trust in scientists believed the world was getting warmer.
