WASHINGTON (AP) — Nearly 4 out of 5 Americans now think temperatures are rising and that global warming will be a serious problem for the United States if nothing is done about it, a new Associated Press-GfK poll finds.

Belief and worry about climate change are inching up among Americans in general, but concern is growing faster among people who don’t often trust scientists on the environment. In follow-up interviews, some of those doubters said they believe their own eyes as they’ve watched thermometers rise, New York City subway tunnels flood, polar ice melt and Midwestern farm fields dry up.

Overall, 78 percent of those surveyed said they thought temperatures were rising and 80 percent called it a serious problem. That’s up slightly from 2009, when 75 percent thought global warming was occurring and just 73 percent thought it was a serious problem. In general, U.S. belief in global warming, according to AP-GfK and other polls, has fluctuated over the years but has stayed between about 70 and 85 percent.

The biggest change in the polling is among people who trust scientists only a little or not at all. About 1 in 3 of the people surveyed fell into that category.

Within that highly skeptical group, 61 percent now say temperatures have been rising over the past 100 years. That’s a substantial increase from 2009, when the AP-GfK poll found that only 47 percent of those with little or no trust in scientists believed the world was getting warmer.

This is an important development because, often in the past, opinion about climate change doesn’t move much in core groups — like those who deny it exists and those who firmly believe it’s an alarming problem, said Jon Krosnick, a Stanford University social psychologist and pollster. Krosnick, who consulted with The Associated Press on the poll questions, said the changes the poll shows aren’t in the hard-core “anti-warming” deniers, but in the next group, who had serious doubts.

“They don’t believe what the scientists say, they believe what the thermometers say,” Krosnick said. “Events are helping these people see what scientists thought they had been seeing all along.”

Phil Adams, a retired freelance photographer from Washington, North Carolina, said he was “fairly cynical” about scientists and their theories. But he believes very much in climate change because of what he’s seen with his own eyes.

“Having lived for 67 years, we consistently see more and more changes based upon the fact that the weather is warmer,” he said. “The seasons are more severe. The climate is definitely getting warmer.”

“Storms seem to be more severe,” he added. Nearly half, 49 percent, of those surveyed called global warming not just serious but “very serious,” up from 42 percent in 2009. More than half, 57 percent, of those surveyed thought the U.S. government should do a great deal or quite a bit about global warming, up from 52 percent three years earlier.

But only 45 percent of those surveyed think President Barack Obama will take major action to fight climate change in his second term, slightly more than the 41 percent who don’t think he will act.

Overall, the 78 percent who think temperatures are rising is not the highest percentage of Americans who have believed in climate change, according to AP polling. In 2006, less than a year after Hurricane Katrina devastated New Orleans, 85 percent thought temperatures were rising. The lowest point in the past 15 years for belief in warming was in December 2009, after some snowy winters and in the middle of an uproar about climate scientists’ emails that later independent investigations found showed no manipulation of data.

Broken down by political party, 83 percent of Democrats and 70 percent of Republicans say the world is getting warmer. And 77 percent of independents say temperatures are rising. Among scientists who write about the issue in peer-reviewed literature, the belief in global warming is about 97 percent, according to a 2010 scientific study.

The AP-GfK poll was conducted Nov. 29-Dec. 3 by GfK Roper Public Affairs and Corporate Communications. It involved landline and cellphone interviews with 1,002 adults nationwide. Results for the full sample have a margin of error of plus or minus 3.9 percentage points; the margin of error is larger for subgroups.

How the AP-GfK Poll was conducted

The Associated Press-GfK poll on climate change was conducted by GfK Roper Public Affairs & Corporate Communications from Nov. 29 to Dec. 3. It is based on landline telephone and cellphone interviews with a nationally representative random sample of 1,002 adults. Digits in the phone numbers dialed were generated randomly to reach households with unlisted and listed landline and cellphone numbers.

 

Interviews were conducted in both English and Spanish.

 

As is done routinely in surveys, results were weighted, or adjusted, to ensure that responses accurately reflect the population’s makeup by factors such as age, sex, education and race. In addition, the weighting took into account patterns of phone use — landline only, cellphone only and both types — by region.

 

No more than 1 time in 20 should chance variations in the sample cause the results to vary by more than plus or minus 3.9 percentage points from the answers that would be obtained if all adults in the U.S. were polled.

 

There are other sources of potential error in polls, including the wording and order of questions.

AP-GfK Poll: Election indicators suggest GOP edge

By, JENNIFER AGIESTA, Associated Press

(AP) – The latest Associated Press-GfK poll holds bad news for President Barack Obama, but as the November elections draw closer, there are ominous signs for congressional Democrats as well.

A look at the key findings from the March poll on this year’s election and the burgeoning 2016 presidential field.

GOP GAINING GROUND

Preferences for control of Congress are tight, but Republicans have gained on Democrats since January. Thirty-six percent in last month’s poll said they would rather see the Democrats in charge of Congress and 37 percent chose Republicans.

Democrats held a narrow advantage on that question in January, when 39 percent favored the Democrats and 32 percent the Republicans.

Democrats are in the majority in the Senate while Republicans run the House.

The shift stems largely from a change among those most interested in politics.

In the new poll, registered voters who are most strongly interested in politics favored the Republicans by 14 percentage points, 51 percent to 37 percent. In January, this group was about evenly split, with 42 percent preferring Democrats and 45 percent the Republicans.

That’s not the only positive sign in the poll for the Republicans.

Favorable views of the GOP have improved, with 38 percent overall now saying they hold a favorable impression of the Party. Republicans’ positive view of their own party has increased from 57 percent in January to 72 percent now.

Even impressions of the tea party movement have shifted more positive in recent months. GOP favorability still lags behind that of the Democrats, however, with 43 percent holding a favorable view of the Democratic Party.

CONGRESSIONAL APPROVAL STAGNANT

Congressional approval is stagnant and negative, with just 16 percent saying they approve while 82 percent disapprove. Among those who have “a great deal” or “quite a bit” of interest in politics, 90 percent disapprove, including 61 percent who strongly disapprove.

Nearly 4 in 10 (39 percent) would like to see their own member of Congress re-elected, an improvement since January. Among registered voters who say they pay a great deal of attention to politics, 44 percent say they would like to see their current member re-elected, compared with 33 percent in January.

Here, there’s a glimmer of hope for Democrats. Those who consider themselves Democrats are now more likely than Republicans to say their own member of Congress ought to be re-elected. Not all Democrats live in districts represented by Democrats, of course, but it represents a shift in opinion since January.

WHO’S IN CHARGE

With control of Congress divided between the parties, most Americans say Obama has a lot or quite a bit of control over what the federal government does, outpacing the share who say the Democrats or Republicans in Congress are in control.

Partisans tend to see the opposition as the controlling force, with Republicans more apt than Democrats to see Obama in charge, and Democrats more likely to say the Republicans have the upper hand.

Six in 10 (62 percent) of those with a great deal or quite a bit of interest in politics say Obama has a lot or quite a bit of control of what the federal government does. Just half (51 percent) of those closely attuned to politics say Democrats in Congress exert a similar influence over what the federal government does and 40 percent say the same about Republicans in Congress.

There’s little change since December in which party Americans trust more to handle major issues.

Democrats’ strong points are on handling social issues, including same-sex marriage (31 percent prefer Democrats, 17 percent the Republicans) and abortion (30 percent prefer Democrats, 22 percent Republicans). Republicans have the edge on protecting the country, 34 percent to 16 percent, a slightly wider margin than they held on the question in December.

LOOKING TO 2016? NOT SO MUCH

The poll measured impressions of 19 potential 2016 presidential candidates, and found that a majority of those surveyed offered an opinion about just seven of them. The other 12 have quite a lot of introducing themselves to do if they are to make a run for the White House.

Most people said either they hadn’t heard of them or skipped the question.

Hillary Rodham Clinton generated the most positive response of the bunch, with 46 percent viewing the former secretary of state and first lady favorably and 39 percent unfavorably.

Among potential GOP contenders, none generated a net positive reaction from the public, with 2012 vice presidential nominee Paul Ryan faring best – 27 percent viewed him favorably, 29 percent unfavorably.

Among Republicans, majorities have favorable impressions of Ryan and former Arkansas Gov. Mike Huckabee. But in a sign that the past isn’t always prologue, nearly half of Republicans say they don’t know enough to have an opinion about former Sen. Rick Santorum of Pennsylvania, a large factor in the 2012 nomination fight.

The AP-GfK Poll was conducted March 20-24, 2014 using KnowledgePanel, GfK’s probability-based online panel designed to be representative of the U.S. population. It involved online interviews with 1,012 adults, and has a margin of sampling error of plus or minus 3.4 percentage points for all respondents.

Respondents were first selected randomly using phone or mail survey methods, and were later interviewed online. People selected for KnowledgePanel who didn’t otherwise have access to the Internet were provided with the ability to access the Internet at no cost to them.
