WASHINGTON — Americans seem to be cooling toward global warming.

Majority support emissions standards

Despite misgivings about the science, half the respondents still say they support limits on greenhouse gases, even if they could lead to higher energy prices. And a majority — 56 percent — feel the United States should join other countries in setting standards to address global climate change.

But many of the supporters of reducing pollution have heard little to nothing about cap-and-trade, the main mechanism for reducing greenhouse gases favored by the White House and central to legislation passed by the House and a bill the Senate will take up next week.

Under cap-and-trade, a price is put on each ton of pollution, and businesses can buy and sell permits to meet emissions limits.

"Perhaps the most interesting finding in this poll … is that the more Americans learn about cap-and-trade, the more they oppose cap-and-trade,” said Sen. James Inhofe, R-Tulsa, who opposes the Senate bill and has questioned global warming science.

Just 57 percent think there is solid evidence the world is getting warmer, down 20 points in just three years, a new poll says. And the share of people who believe pollution caused by humans is causing temperatures to rise has also taken a dip, even as the U.S. and world forums gear up for possible action against climate change.

In a poll of 1,500 adults by the Pew Research Center for the People & the Press, released Thursday, the number of people saying there is strong scientific evidence that the Earth has gotten warmer over the past few decades is down from 71 percent in April of last year and from 77 percent when Pew started asking the question in 2006.

The steepest drop has occurred during the past year, as Congress and the Obama administration have taken steps to control heat-trapping emissions for the first time and international negotiations for a new treaty to slow global warming have been under way. At the same time, there has been mounting scientific evidence of climate change — from melting ice caps to the world’s oceans hitting the highest monthly recorded temperatures this summer.

The poll was released a day after 18 scientific organizations wrote Congress to reaffirm the consensus behind global warming. A federal government report Thursday found that global warming is upsetting the Arctic’s thermostat.

"The priority that people give to pollution and environmental concerns and a whole host of other issues is down because of the economy and because of the focus on other things,” suggested Andrew Kohut, the director of the research center.

Since 1997, the percentage of Americans that believe the Earth is heating up has remained constant — at around 80 percent — in polling done by Jon Krosnick of Stanford University. Krosnick, who has been conducting surveys on attitudes about global warming since 1993, described the decline in the results as "implausible.”
