Public Perceptions of the Health Consequences of Global Warming

Public Perceptions of the Health Consequences of Global Warming

A new report, Public Perceptions of the Health Consequences of Global Warming, analyzing results from our national survey conducted in October 2014, finds that Americans are generally unaware of the potential health consequences of global warming. When asked what global warming-related health problems, if any, Americans are experiencing, only about one in four respondents (27%) named at least one health problem known to be related to global warming.

Americans Support CO2 Limits on Existing Coal-Fired Power Plants

Despite the debate in Congress over proposed EPA regulations, a solid majority of Americans (67%) support setting strict carbon dioxide emission limits on existing coal-fired power plants to reduce global warming and improve public health, according to our October 2014 survey.

Global Warming’s Human Health Impacts Poorly Understood by Americans

Global Warming’s Human Health Impacts Poorly Understood by Americans

In our spring 2014 national survey, we asked Americans to give us their best estimates of the impacts of global warming on human health worldwide – currently and 50 years from now. The largest proportion of respondents (38% to 42%) simply said, “I don’t know.” The next largest proportion (27% to 39%) said either “no one” or “hundreds” of people worldwide will die, be made ill or injured by global warming each year, either now or 50 years from now.

Only 18% to 32% of Americans said, correctly, that each year either “thousands” or “millions” of people worldwide will die, be made ill or injured by global warming, either now or 50 years from now.

What’s In A Name? Global Warming vs Climate Change

What’s In A Name? Global Warming vs Climate Change

A nationally representative survey finds that the terms “global warming” and “climate change” often mean different things to Americans—and activate different sets of beliefs, feelings, and behaviors, as well as different degrees of urgency about the need to respond.

How Stable is Earth’s Climate?

Americans have very different mental models of the stability of the climate system. In a nationally representative study, we examined Americans’ understanding of how the climate system works. Survey respondents were presented with the following question:

“People disagree about how the climate system works. The five pictures below illustrate five different perspectives. Each picture depicts the Earth’s climate system as a ball balanced on a line, yet each one has a different ability to withstand human-caused global warming. Which one of the five pictures best represents your understanding of how the climate system works?”

Fragile: Earth's climate is delicately balanced. Small amounts of global warming will have abrupt and catastrophic effects.

Threshold: Earth's climate is stable within certain limits. If global warming is small, climate will return to a stable balance; if it is large, there will be dangerous effects.

Gradual: Earth's climate is gradual to change. Global warming will gradually lead to dangerous effects.

Random: Earth's climate is random and unpredictable. We do not know what will happen.

Stable: Earth's climate system is very stable. Global warming will have little or no effects.

Most respondents chose the Threshold model (34%), followed by the Gradual (24%), Random (21%), Fragile (11%) and Stable (10%) models. Scientifically, at different temporal or spatial scales the climate system can exhibit each of these behaviors, but the best overall answer is the threshold model.

Extreme Weather and Climate Change in the American Mind in November 2013

Extreme Weather and Climate Change in the American Mind in November 2013

Highlights:

  • Compared to the record-setting extreme weather disaster years of 2011 and 2012, the year 2013 in the United States was relatively calm, with no land-falling hurricanes, fewer tornadoes, and drought relief in the Great Plains. In turn, fewer Americans say they experienced an extreme weather event last year. People in the Northeast, Midwest, and South, however, were more likely to report experiencing extreme cold or a snowstorm in 2013 than they did in 2012.
  • Over half of Americans (56%) say “global warming is affecting weather in the United States.”
  • A large majority of Americans say their state and local government should make it a priority to protect public water supplies (78%), transportation/roads/bridges (73%), people’s health (72%), the electricity system (71%), agriculture (70%), and public sewer systems (69%) from extreme weather over the next 10 years.
