Poll: US belief in warming rises with thermometer

WASHINGTON (AP) — Americans’ belief in global warming is on the rise, along with temperatures and surprising weather changes, according to a new university poll.

The survey by the University of Michigan and Muhlenberg College says 62 percent of those asked last December think the Earth is getting warmer. That’s up from 55 percent in the spring of that year and 58 percent in December 2010. It’s the highest proportion in two years.

Nearly half the people who say they believe in global warming base that on personal observations of the weather. Climate researchers say that’s reaching the correct conclusion for reasons that aren’t quite right.

When asked an open-ended question about why they thought the Earth was warming, one-quarter of those surveyed pointed to temperatures they experience and another quarter cited other weather changes. One in 7 mentioned melting glaciers and polar sea ice, and 1 in 8 noted media coverage. Only 8 percent mentioned scientific research.

“It seems to be driven by an increased connection that the public is making between what they see in terms of weather conditions and climate change,” said Chris Borick, the director Muhlenberg College Institute of Public Opinion.

The poll was conducted from Dec. 4 to Dec. 21, after the U.S. experienced a record 14 billion-dollar weather disasters in 2011, including killer tornadoes, an unusual northeastern hurricane, a devastating southwestern drought and floods along major rivers.

At the same time, this poll was done before the official start of winter, so people were not yet affected by what has been a mild season for many regions.

Borick said that after the previous two winters, which were quite snowy, belief in global warming dropped dramatically. So he says the findings from a fresh poll to be done in upcoming weeks may again reflect views based on the latest weather trend.

Climate scientists say daily local weather isn’t evidence of climate change. But they also say long-term climate change is so dramatic that people recognize and experience it.
