So the more important question for us is, what do 'expert' climate scientists think? When compared with pres levels, do you think that mean global temperatures have generally risen, fallen, or remained relatively constant?

Do you think human activity is a significant contributing factor in changing mean global temperatures? Source: Pew Research Center. Changing scientific opinion In the Gallup organization conducted a telephone survey on global climate change among scientists drawn from membership lists of the American Meteorological Association and the American Geophysical Union. We repeated several of their questions verbatim, in order to measure changes in scientific opinion over time.

On a variety of questions, opinion has consistently shifted toward increased belief in and concern about global warming. Among the changes:. Source: George Mason University. There is a hoax going on, but it's not what some claim. Learn now to separate fact from fiction and reason from rhetoric to learn who is really 'tricking' you.

A minority of Americans perceive that the best available scientific evidence is driving climate research findings most of the time. And a roughly equal share says other, more negative, factors influence climate research.

It then details the divides in these views among political groups and among those who are more or less concerned about climate issues. Americans who care more about the issue of climate change, regardless of political orientation, are more trusting of climate scientists, more likely to expect negative effects to occur because of climate change, and more likely to believe that both individual efforts and policy actions can be effective in addressing climate change. At least three-quarters of Americans say that harm to animal habitats and plant life is very or fairly likely to occur.

A similar share expects storms to become more severe and damage to shorelines or more frequent droughts to occur. There are a number of different proposals to address climate change. The Obama administration announced stricter limits on power plant emissions in This year, more than countries , including the U.

Public assessments of other policy proposals are similar. A majority of Americans say that climate scientists should have a role in policy decisions about climate issues.

By comparison, fewer Americans believe elected officials should have a major role in climate policy decisions. Public views about the role of elected officials in policy decisions on climate issues may tie with deep public cynicism about the federal government , generally. Or, as shown later in this chapter, those beliefs could tie to distrust that elected officials provide full and accurate information about the causes of climate change.

Scientists first noted the possibility that the burning of greenhouse gases, such as fossil fuels, could increase temperatures back in the s. A report from National Academy of Sciences in warned that the burning of fossil fuels could result in average temperatures increases of 6 degrees Celsius by the year Among those who say climate change is due to human activity, many more say scientists are in agreement on the main cause of climate change.

Americans hold relatively positive views about climate scientists, compared with other groups, as credible sources of information.

Far more Americans say they trust information from climate scientists on the causes of climate change than say they trust either energy industry leaders, the news media or elected officials.

But in absolute terms, public trust in information from climate scientists is limited. Public trust in information from the news media, energy industry leaders and elected officials is significantly lower, however. A majority of Americans report having not too much or no trust in information from these groups about the causes of climate change. But majorities say these less germane motivations influence results at least some of the time.

Throughout this report, Republicans and Democrats include independents and other non-partisans who lean toward the parties.

Partisan leaners tend to have attitudes and opinions very similar to those of partisans. On questions about climate change and trust of climate scientists, there are wide differences between those who lean to the Democratic Party and those who lean to the Republican Party.

And leaners and partisans of their party have roughly the same positions on these questions. Political divides are dominant in public views about climate matters.

Consistent with past Pew Research Center surveys , most liberal Democrats espouse human-caused climate change, while most conservative Republicans reject it. People on the ideological ends of either party, that is liberal Democrats and conservative Republicans, see the world through vastly different lenses across all of these judgments.

As with previous Pew Research Center surveys , there are wide differences among political party and ideology groups on whether or not human activity is responsible for warming temperatures. Pew Research Center surveys have found these kinds of wide political gaps in previous years. About six-in-ten or more of liberal Democrats say it is very likely that climate change will bring droughts, storms that are more severe, harm to animal and plant life, and damage to shorelines from rising sea levels.

There is wide gulf between liberal Democrats and conservative Republicans when it comes to beliefs about how to effectively address climate change. And, at least half of liberal Democrats say that both personal efforts to reduce the carbon footprint of everyday activities and more people driving hybrid and electric vehicles can make a big difference in addressing global warming.
