On Renewable Energy and Climate, Trump Voters Stand Apart

In this brief, author Larry Hamilton discusses the results of pre- and post-election Polar, Environment, and Science surveys carried out by Carsey School researchers in August and November–December 2016, asking people about their general views on climate change and renewable energy. Almost three-fourths of Americans surveyed said that renewable energy should be a higher national priority than more drilling for oil. About two-thirds agree with the scientific consensus that humans are changing Earth’s climate. Priority for renewable energy development and recognition of human-caused climate change are majority opinions within every voter group except Trump supporters. On renewable energy, the reality of climate change, and doing something about it, Trump voters stand apart not only from Clinton voters but also from voters for third-party candidates and from nonvoters

Trump and Sanders Supporters Differ Sharply on Key Scientific Fact

In this fact sheet, author Lawrence C. Hamilton reports the results of a recent WMUR/CNN poll by the UNH Survey Center asking more than 700 New Hampshire residents whether they would vote for Donald Trump or Bernie Sanders if the 2016 presidential election was being held on that day, and how candidate preferences matched up with people\u27s beliefs about a basic scientific fact -- the rising con­centration of CO2 or carbon dioxide in the Earth’s atmosphere

Public awareness of the scientific consensus on climate

Questions about climate change elicit some of the widest political divisions of any items on recent U.S. surveys. Severe polarization affects even basic questions about the reality of anthropogenic climate change (ACC), or whether most scientists agree that humans are changing the Earth’s climate. Statements about scientific consensus have been contentious among social scientists, with some arguing for consensus awareness as a “gateway cognition” that leads to greater public acceptance of ACC, but others characterizing consensus messaging (deliberate communication about the level of scientific agreement) as a counterproductive tactic that exacerbates polarization. A series of statewide surveys, with nationwide benchmarks, repeated questions about the reality of ACC and scientific consensus many times over 2010 to 2016. These data permit tests for change in beliefs and polarization. ACC and consensus beliefs have similar trends and individual background predictors. Both rose gradually by about 10 points over 2010 to 2016, showing no abrupt shifts that might correspond to events such as scientific reports, leadership statements, or weather. Growing awareness of the scientific consensus, whether from deliberate messaging or the cumulative impact of many studies and publicly engaged scientists, provides the most plausible explanation for this rise in both series. In state-level data, the gap between liberal and conservative views on the reality of ACC did not widen over this period, whereas the liberal–conservative gap regarding existence of a scientific consensus narrowed

Do You Trust Scientists About the Environment?

In this brief, author Lawrence Hamilton examines the results of a Granite State Poll conducted by the University of New Hampshire Survey Center in late January–early February 2014. The poll asked about public trust in scientists, along with other questions on science, political, and social issues that help to place the science-trust results in perspective. Almost two-thirds of New Hampshire residents surveyed say that they trust scientists to provide accurate information about environmental issues. Only 12 percent do not trust scientists to provide this information. Wide disparities occur along party lines, however, regarding this and other questions about science. The 53 percent gap between Democrats and Republicans on climate change is one of the largest for any issue. Trust in scientists shows a somewhat narrower Democrat–Republican gap (37 percent), which is larger than those for historically divisive social issues such as abortion or the death penalty. Answers to these survey questions also relate to respondents’ news media sources, even after statistical adjustments for political party, age, gender and education. People who often listen to New Hampshire Public Radio are more likely to say they trust scientists, and respond differently from other New Hampshire residents on several other science-related questions. People who often watch local television news or read newspapers, on the other hand, respond differently on questions about the death penalty or gun control

Do scientists agree about climate change? public perceptions from a New Hampshire survey

This report, a collaboration of the Carsey Institute, the UNH Survey Center, and the UNH Office of Sustainability, is the first of a new initiative that will track public perceptions about climate change as they change over time. Questions related to climate change were asked as part of New Hampshire\u27s Granite State Poll, which surveyed 512 New Hampshire residents in April 2010
