While politicians often assume that people in "red" and "blue" states have very different ideologies regarding climate change, an analysis of surveys measuring Americans' opinions tells a different story.
Jon Krosnick, a senior fellow with the Stanford Woods Institute for the Environment, presented the findings today in Washington to the congressional Bicameral Task Force on Climate Change.
Majorities of residents in every state surveyed said the government should limit greenhouse gas emissions by businesses and, in particular, by power plants, Krosnick said. Majorities also favored a cap-and-trade system to limit emissions; tax breaks to encourage the production of energy from the sun, wind and water; carbon sequestration; and government regulations or tax breaks to require or encourage improvements in the energy efficiency of automobiles, appliances and buildings. No state had a majority of residents opposed to any of those policies.
"The consistency of findings across states was surprising to me," said Krosnick, a professor of communication and political science, who worked with Woods Institute visiting scholar Bo MacInnis on the project. "I have often heard legislators in Washington express the belief that there is considerable variation in opinions about global warming across parts of the country, and that most of the people living in their state or district are skeptical about global warming."
"When I ask about the polling they have done that led them to this belief, I have routinely been told that they had not done polling and, instead, base their impressions on phone calls, emails and conversations with and from constituents on the issue," Krosnick continued. "Our findings suggest that the balance of those direct communications from constituents to elected representatives may have created a misimpression of the public's opinions on the issue."
Krosnick reached these conclusions by conducting what social scientists call a "secondary analysis" of existing data from national surveys that measured public opinion in nearly every state on various issues related to global warming. He added data collected in surveys of representative samples of residents in a collection of states. The 21 surveys analyzed (mostly by Stanford) were primarily conducted between 2006 and 2013. Data from 19,751 respondents were analyzed. Four states had insufficient data: Alaska, Hawaii, North Dakota and Wyoming.
Findings from Krosnick's analysis include:
- In the states examined, majorities consistently said the U.S. should take action to limit its emissions regardless of what other nations do.
- Majorities in nearly all states endorsed having the federal government do more than it is doing now to deal with global warming. Exceptions were Idaho (45 percent endorsed doing more), Montana (48 percent), Nevada (47 percent) and Utah (46 percent).
- In no state did even a near-majority endorse increasing consumption taxes levied on gasoline or electricity use.
- In only one state did a clear majority endorse giving government tax breaks to encourage building of more nuclear plants: South Carolina, where 64 percent favored that action. Bare majorities endorsed tax breaks to encourage construction of nuclear plants in Connecticut (52 percent), Minnesota (53 percent) and Louisiana (50 percent).
- Support for government efforts to encourage building of all-electric cars was notably lower than other policy approaches. The largest endorsement came from the states of Washington, New Jersey, Iowa and Kansas, which all favored the proposal by 68 percent.
- Engagement with global warming issues was consistent across states. In most states, between 50 and 70 percent of those surveyed said they were highly knowledgeable about the issue. The lowest self-reported knowledge levels were observed in Alabama (38 percent) and West Virginia (29 percent).
The statistical modeling procedure estimated differences in opinions between states while taking into account the effects of each survey mode (e.g., telephone interviewing vs. self-completion of Internet questionnaires) on expressed opinions, differences between results obtained by different data collection firms and sponsored by different organizations, the effects of the season when the survey took place, and other factors. The results of the statistical modeling were measurements of opinions in each state in 2012-13 gauged via random-digit-dialed telephone surveys sponsored by Stanford.

High up in the mountains of Montana's Glacier National Park, there are two species of insect that only a fly fishermen or entomologist would probably recognize. Known as stoneflies, these aquatic bugs are similar to dragonflies and mayflies in that they spend part of their lives underwater before emerging onto the land, where they transform into winged adults less than a half inch long. However, unlike those other species, stoneflies do their thing only where cold, clean waters flow.

The year is less than four weeks old, but scientists already know that carbon dioxide emissions will continue to head upwards — as they have every year since measurements began — leading to a continuation of the Earth's rising heat.
