How to talk about climate change

The United Nations' Intergovernmental Panel on Climate Change released a report last fall warning of a catastrophic effect on the world's people, environment and economy if temperatures rise by more than 1.5 degrees Celsius, which could happen as soon as 2040. But meaningful action to stop climate change is not possible without political will, and despite overwhelming scientific evidence of global warming, there are still many who don't believe in it or consider it a matter of grave concern.

Risa Palm, professor of geosciences and the university's provost for the past 10 years, is studying how attitudes toward are formed, and how they might change depending on the way the issue is framed.

"Most people do accept that the is changing as a result of human activity," says Palm. "But there is a skeptical and powerful minority who either do not believe that climate change is a serious problem or that our actions are making it worse."

In 2017, she and her colleagues in the Andrew Young School of Policy Studies analyzed data from a panel of 9,500 respondents who were asked the same question about climate change in 2010 and 2014. They found that direct experience with , drought and weather-related natural disasters had a very small impact on the respondents' acceptance of climate change. What did matter was whether they identified as a Democrat or a Republican. Between 2010 and 2014, Americans' opinions about climate change became more polarized by , increasingly aligning with those of others in the same .

"Once attitudes are politicized, they are difficult to change," says Palm. "Once a position has been taken, such as loyalty to a team, people reject new information as tainted or propaganda."

Political attitudes toward climate change may not be completely intractable, though. In the 1970s, after all, the United States took bipartisan action to limit aerosols and reduce air pollution, and founded the Environmental Protection Agency.

So what could convince climate change skeptics to change their minds? Palm believes that focusing on the economics of climate change—such as its effect on housing markets in areas of sea level rise, flooding and wildfires—could be key.

"In places like South Florida, we may see higher interest rates on home loans or additional mortgage insurance requirements," Palm says. "There is already research showing that coastal properties are being affected by lower prices, and lenders and insurers are being advised to take such factors into account."

The challenge, she says, is how to navigate the country's highly-partisan environment so that those in the skeptical minority can join with others to tackle the problem. In this way, the U.S. differs from nearly all other countries, where party identification matters less when it comes to attitudes about climate change. In 2018, Palm contributed to a study showing that globally, the biggest predictor of climate change concern is not party affiliation, but belief in democratic values.

"Climate change is a global problem that requires a global solution," says Palm. "By gaining a clearer understanding of who is most likely to oppose climate change actions and how to reach them, we can identify an effective way to overcome bias to get people to agree to take action. There is a lot more to do here."
