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: Trump supporters unfazed by reversal on self-funding

By JULIE BYKOWICZ and EMILY SWANSON

WESTFIELD, Ind. (AP) — Donald Trump’s voters adored him for mostly paying his own way in the first half of the presidential campaign. Yet those same people are shrugging their shoulders now that he’s raising money just like the rivals he once disparaged as the “puppets” of big donors.

A new Associated Press-GfK poll found that 63 percent of Trump supporters say they’re at least somewhat more likely to back a self-funded candidate, just as he once was. However, just 13 percent consider it a problem that Trump changed his mind — and nearly all those think it’s only a minor one.

How can people care so strongly about a candidate’s original stance and then not care at all when he changes his mind?

At a Trump rally this week near Indianapolis, some of his most ardent supporters explained their thinking. Many said it wouldn’t be fair for Trump, a billionaire businessman, to have to spend his own money against Hillary Clinton. The presumptive Democratic nominee and her allies aim to raise $1 billion for the general election.

“It was inspiring to see someone spend their own money rather than relying on lobbyists,” said 18-year-old Maxwell Nugent, who will be casting his first presidential vote for Trump this November. “It makes it more profound for him to be asking all the people who supported him to be giving money to the campaign now.”

Nugent, who wore a black T-shirt that reads: “Hillary’s Lies Matter,” said he likes that Trump “started from the bottom, with no donors.”

So far, Trump has put about $50 million of his own money into his campaign, mostly through personal loans which he says he will not seek to recoup. But he assembled a fundraising operation two months ago and has raised more than $51 million for his campaign and Republican Party allies.

Others who attended the Indiana rally said they have some concerns about Trump raising money — but also have faith that he won’t bend his policies to appease donors.

“A big thing with me is that since he is a billionaire, he doesn’t need to be bought,” said Diane Martinez, who lives in Westfield, Indiana, and leads a group called Save Our Veterans that supports Trump.

Trump has lamented the influence that super-donors such as Charles and David Koch and Sheldon Adelson hold over Republican politicians, naming those three specifically.

Yet he’s now developing a relationship with Adelson, a billionaire Las Vegas gaming executive, that could unleash streams of money to help him win the election. The Koch brothers have no plans to back Trump.

Americans have a negative view of the amount of money in politics. An AP-NORC poll conducted in November of 2015 found that 8 in 10 Americans, Republicans and Democrats alike, think campaign contributions influence the decisions that elected officials make.

Trump supporters are among those who see an issue with the way campaign funding works. In the AP-GfK poll, 51 percent of Trump supporters call the way presidential candidates raise money for their campaigns very or extremely important to them, similar to the 46 percent of all Americans who say that.

“We need absolute reform,” said Victor Wakley, another Save Our Veterans member at the Indiana rally for Trump. “I loved that he was paying his own way, and I do have some concerns now that he’s not.”

Democrat Bernie Sanders, who solicited only small donations online and held no traditional fundraisers, made campaign finance reform a pillar of his presidential campaign. Clinton also has promised to press for an end to unlimited money that flows into campaigns through super political action committees, although she is making full use of those groups in her 2016 bid.

Trump has called super PACs “corrupt” but offered no policy proposals about campaign finance. He’s also stopped talking about the corrosive effect of donor money since he began raising it.

In an AP interview this spring, Trump said he is raising money only to help the Republican Party, and he has repeatedly said it would be easier for him to just write a big check to his own campaign. He also stresses that his campaign fundraising is coming from small donors, the way Sanders’ fundraising was.

None of those statements is entirely true.

Trump’s fundraising deal with the party includes a provision that the first $2,700 of any donation go to his campaign. The rest of it — up to about $500,000 per donor — is divided among the national party and some state Republican groups.

Online solicitations accounted for less than half of the money Trump raised in late May and June, and it’s not clear how much of it was from small donors. Fundraising reports to federal regulators are due Wednesday night.

On Trump’s self-funding reversal, 16 percent of all Americans polled by AP-GfK considered it a major problem and 21 percent a minor problem.

Among Clinton supporters, 26 percent say they’re at least somewhat more likely to support a candidate who’s funding his or her own campaign, but more than half say they consider Trump’s reversal to be a problem, including 27 percent who say they think it’s a major problem.

The Trump supporters say it’s no surprise Democrats are trying to emphasize Trump’s switch from self-funding to traditional funding.

“There are a couple of ways to look at it,” said Jerry Loza, a Trump supporter at the Indiana rally. “You could say it’s hypocrisy. You could also say it’s a different game now.”

The AP-GfK Poll of 1,009 adults was conducted online July 7-11, using a sample drawn from GfK’s probability-based KnowledgePanel, which is designed to be representative of the U.S. population. The margin of sampling error for all respondents is plus or minus 3.3 percentage points.

Respondents were first selected randomly using telephone or mail survey methods and later interviewed online. People selected for KnowledgePanel who didn’t have access to the Internet were provided access for free.

AP-GfK Poll: Voters split over how to secure US from illegal immigration
By EMILY SWANSON and VIVIAN SALAMA

WASHINGTON (AP) — Most Americans reject Donald Trump’s proposal to build a wall along the U.S. border with Mexico and his support for deporting those in the country illegally. But they’re divided on the presumptive Republican nominee’s proposed temporary ban on the entry of Muslims from other countries, a new survey finds.

The poll shows Trump’s shifting rhetoric on that ban might win some Americans over.

When it comes to Trump’s proposal to build a wall along the Mexican border, about 6 in 10 Americans oppose the idea while 4 in 10 are for it, the new Associated Press-GfK poll indicated.

Similarly, 6 in 10 Americans favor providing a way for immigrants who are in the country illegally to become U.S. citizens, while about 4 in 10 are opposed.
Seventy-six percent of Democrats, along with 44 percent of Republicans, favor a path to citizenship for immigrants in the country illegally. Among Trump’s supporters, just 38 percent are in favor of a path to citizenship. Sixty-seven percent of Republicans and just 21 percent of Democrats favor a border wall. Three-quarters of Trump’s supporters favor that proposal.

Trump’s likely rival, Democrat Hillary Clinton, has cast his calls for the border wall and temporary foreign Muslims ban as dangerous.

Trump supporter Marile Womack, 79, of Debary, Florida, adamantly favors the border wall. No one else “had the guts to do it,” she said. But the daughter of Austrian immigrants isn’t opposed to immigration from any country so long as it’s done legally.

“I don’t favor banning immigrants, but I am for investigating them before they come,” she said.

In contrast, Mark Wecker, a car salesman from Redding, California, called a border wall stupid, because “it’s a lot of money and it’s not going to keep them out if they want to get in.”

Three-quarters of Latinos, two-thirds of African-Americans and more than half of whites favor providing a path to citizenship. Forty-eight percent of whites, 26 percent of blacks and just 16 percent of Latinos favor a border wall.

Daniella Gil, a stay-at-home-mom from Cornelius, Oregon, who is the daughter of Mexican immigrants, said, “We should be focusing on the violence coming from Syria as opposed to Hispanics jumping the border.”

She said she supports immigration from any country so long as it’s done legally.

Americans are slightly more likely to oppose than favor a temporary ban on Muslims who are not U.S. citizens from entering the United States, by a 52 percent to 45 percent margin that has been strikingly consistent in AP-GfK polls conducted this year.

Sixty-nine percent of Republicans say they favor the temporary ban on Muslim immigration, while 68 percent of Democrats are opposed. Half of whites and just a third of non-whites say they favor the ban. Seventy-six percent of Trump supporters are in favor.

On a trip to Scotland last month, Trump shifted his rhetoric, saying he would instead “want terrorists out” of the U.S., and to do so, he would limit people’s entry from “specific terrorist countries and we know who those terrorist countries are.”

The poll indicates that rhetorical shift could win support. Among those asked more broadly about a temporary ban on immigrants from areas of the world where there is a history of terrorism against the U.S. or its allies, 63 percent are in favor and 34 percent opposed. Ninety-four percent of Trump supporters say they favor this proposal, as do 45 percent of Clinton supporters.

“That’s a necessity for creating stability,” said Ryan Williams, 40, a health care provider from Jacksonville, North Carolina.

Most Americans — 53 percent — think the United States is currently letting in too many refugees from Syria, engulfed in civil war since 2011 and the Islamic State militant group’s de facto center. President Barack Obama has pledged to admit some 10,000 Syrian refugees this year.

Another 33 percent think the current level is about right, while just 11 percent want to let in more. About 4 in 10 think there’s a very or somewhat high risk of refugees committing acts of religious or political violence in the United States, 34 percent think the risk moderate, and 24 percent consider it very or somewhat low.

Seventy-six percent of Republicans think the U.S. should allow fewer refugees. Among Democrats, 43 percent think the current level is about right, 38 percent think the U.S. should allow fewer, and 18 percent want to allow more.

Said Gil, the stay-at-home mom from Oregon, “Some of those people are innocent kids.”
