WASHINGTON — An overwhelming majority of the American public, including nearly half of Republicans, support government action to curb global warming, according to a poll conducted by The New York Times, Stanford University and the nonpartisan environmental research group Resources for the Future.
In a finding that could have implications for the 2016 presidential campaign, the poll also found that two-thirds of Americans say they are more likely to vote for political candidates who campaign on fighting climate change. They are less likely to vote for candidates who question or deny the science of human-caused global warming.
Among Republicans, 48 percent said they are more likely to vote for a candidate who supports fighting climate change, a result that Jon A. Krosnick, a professor of political science at Stanford University and an author of the survey, called “the most powerful finding” in the poll.
Many Republican candidates either question the science of climate change or do not publicly address the issue.
Never miss a local story.
Nonetheless, 47 percent of Republicans still said they believe that policies designed to curb global warming will hurt the economy.
Although the poll found that climate change was not a top issue in determining a person’s vote, a candidate’s position on climate change influences how a person will vote. For example, 67 percent of respondents, including 48 percent of Republicans and 72 percent of independents, said they were less likely to vote for a candidate who said that human-caused climate change is a hoax.
The results come as climate change is emerging as a source of debate in the coming presidential campaign.
The poll found that 83 percent of Americans, including 61 percent of Republicans and 86 percent of independents, say that if nothing is done to reduce emissions, global warming will be a very or somewhat serious problem in the future.
The nationwide telephone poll was conducted Jan. 7-22 with 1,006 adults and has a margin of sampling error of plus or minus 4 percentage points.
Overall, the number of Americans who believe that climate change is caused by human activity is growing. In a 2011 Stanford University poll, 72 percent of people thought climate change was caused at least in part by human activities. That grew to 81 percent in the latest poll. By party, 88 percent of Democrats, 83 percent of independents and 71 percent of Republicans said that climate change was caused at least in part by human activities.
