TIL what Americans think about climate change

Hello and welcome back to Today I Learned Climate, the show where you learn about climate change from real scientists and experts. I'm your host, Laura Hesse-Fisher from the MIT Environmental Solutions Initiative. This is our first episode of 2021 with a new president here in the United States, President Joe Biden, who has already made climate change one of the top issues of his presidency.

But to make some of the really big changes that our country needs to reduce emissions, we need action from both Republicans and Democrats, in Congress and around the country. So in this episode, we're going to be opening up what Americans think about climate change and what influences their opinion. We'll also look at how this does or doesn't get translated into policy and what's needed to get more action on climate change happening across the country.

For this episode, we spoke with an alum who got her PhD in political science and urban and regional planning here at MIT, and who studies this stuff. My name is Parrish Berquist. I am an assistant professor of public policy at the McCourt School of Public Policy at Georgetown University. Most of my recent work is on public opinion about environmental issues. And the big question that I'm interested in is... how to effectively address climate change within the American political system.

Professor Burquist was part of a program at Yale that, with George Mason University, has been surveying Americans' opinions about climate change for over a decade. We take a bunch of different questions about people's beliefs and attitudes about global warming and use them to categorize people into six different groups based on how concerned they are and how much people know about this problem.

So here's what they found. Let's say you have 10 random Americans in a room. On average, roughly five or maybe six of them will be worried about climate change. The other five are split. Two get that it's happening, but are not worried. Two question or outright deny the science, and one just doesn't care. That's over half the country that thinks that this is an important issue and understands the science behind it. That proportion is pretty high, and it's higher right now than it's ever been.

Yeah, in fact, of the more than 50% of Americans who are worried about climate change, about half of them are really worried. And that number has more than doubled in the past five years.

So how did that happen? Well part of it is that the public is hearing different messages in the media than we were before. The media plays a super important role. And the reason is people, most people do not read scientific reports. They really rely on the media to take these.

scientific reports and translate them into everyday language and sort of summarize them. So for a long time, the overwhelming majority of scientists have understood that the human causes of climate change are the main drivers of the climate.

change that we're experiencing now but through the 90s and early 2000s there was a reluctance on the part of the media to frame the scientific consensus about climate change as an overwhelming scientific consensus, and instead the media would sort of give equal credence to both sides of this issue. Yeah, for decades there has been an overwhelming consensus from scientists that climate change is real and driven by us, by people.

Starting in maybe the mid-2000s, the media started to portray this more realistically. Okay, so... Now Americans know more about climate change. They're seeing it for themselves, and they're more worried about it than ever before. Okay, so great. Sounds like everything is in place for some policy change on climate, right?

Well, this is where the story of public opinion gets more complicated. Because, it turns out, just because something's popular doesn't mean that policymakers are going to sit up and take notice. We can kind of think of two dimensions of public opinion about a particular policy. One is how popular the policy is. The other is how salient it is, which is how much people care about it. accountable and we will make the world the best act. We know that climate action is

popular. There are high numbers of people who support this, but showing politicians that look how many people really care about this issue a lot, you would be rewarded for acting on it. It makes it an easier ask if you can show that it's salient with large numbers of the public. So think about it. What are the top issues on your mind when you cast a ballot? Candidates respond to those issues because they want your vote.

If an issue isn't enough of a priority for you to change your vote, then that pressure's not there. In fact, if you don't have a strong opinion about something... then research has shown that you'll likely adopt the opinion of your political party.

Climate change is a really, it's a complex topic. And that's exactly the kind of issue where people are especially likely to follow the cues of their partisan leaders. They're really likely to sort of adopt the positions that their party officials take. These messages from political figures are also called elite cues.

So when I'm talking about elite cues, we're really talking about like national level. There are people who shape the national level conversation. So the president, national political leaders. One thing that we've seen is that. the words of elites have a major influence in the way that national public opinion moves. So voters tend to sort of adopt the issue position of their favored candidate rather than choosing a candidate that holds their preferred issue position.

This is some wild stuff. You know, we like to believe that if we hear the facts about an issue, we'll form our opinion and then vote for candidates who share those opinions. But that's only for the few issues that we really care about. For complicated, low-priority issues, which for many Americans includes climate change, we're likely to outsource our opinions to the political leaders that we already trust. And depending on who you trust...

you could be getting some very different cues. Climate change is an existential threat to humanity. We have a moral obligation to deal with it. All of this with the global warming and a lot of it's a hoax. It's a hoax. I mean, it's a money-making industry, OK? It's a hoax. A lot of it. And this has, in part, led to where we are today.

Climate change is one of the issues with the strongest partisan divides in the country. So a huge number of Democrats believe that climate change is a huge problem and far fewer Republicans believe that. Remember when we said that more than half of Americans are concerned about climate change? Well, when you break that down by political party, you get a very different story.

In their April 2020 survey, Yale and George Mason found that over 90% of Democrats were worried about climate change, but less than 40% of Republicans were. If you look at the top 10 issues for Republicans in the 2020 election, climate change didn't make the list. There's been a strong effort by the fossil fuel industry and utility companies to support.

particularly Republican elected officials and candidates for office who are dismissive of climate science and who oppose regulatory action that would reduce the clout of the fossil fuel industry. the American economy and in American politics. What that means is that

for congressional districts that elect Democrats versus Republicans, they're sending people to Congress with dramatically different views on this issue. The way our institutions are shaped means that you don't need to... simply mobilize Democrats you have to convince some Republicans as well and that is the much more difficult task I think because of the low salience of the issue on the political right.

But here's the kicker. Surveys show that Republican voters, even if they aren't as worried about climate change, actually like a lot of climate policies. clean energy policies that do earn stronger Republican support. Those are things like government support of renewable energy research, tax incentives for clean vehicles, and things like that. And I think people in general tend to support things that are going to have either a low cost or they're going to actually provide benefits to them.

Across the board, the public tends to be more supportive of regulatory approaches for the same reason. They don't see the cost directly. After the 2020 election, Yale and George Mason surveyed voters about their opinions on different climate policies. And they found that over 50% of Republicans... support regulating carbon dioxide as a pollutant, building solar and wind farms on public lands, and funding more research into renewable energy. And Democrats support these policies too.

I think you have to work with the political realities that we have and push policies that are more popular now. Tying climate action to economic benefits has been shown to build public support for climate action in the U.S. So there are policies that get both Republican and Democrat support. But as we've learned in this episode, public support isn't enough.

You need support and the issue to be a priority to get real change to happen. There's been a lot of work by the environmental movement to raise the salience of climate change, and I think you've seen that in... a shift towards Democrats seeing this issue as much more important. And that just has not happened on the political right. There haven't been grassroots organizations.

trying to raise the salience of this issue and having as much success as they have on the political left. There are groups trying to sort of mobilize conservatives around climate change, but they haven't gotten off the ground to the same extent. And they're working against a really strong effort to undermine the salience of climate change within the Republican Party by the same sort of fossil fuel interests that we've talked about already.

What communication experts know is that people listen to other people that they trust. And there are a bunch of conservative groups out there that are trying to push climate action. There's Republic EN, there's the American Conservation Coalition, Conservation Hawks, Deploy US, the Conservative Caucus of the Citizens' Climate Lobby, and the list goes on.

In our show notes, we'll provide our list of politically conservative individuals and groups advocating for action on climate change. Because the science of climate change isn't a political issue. But how to deal with it is. And the MIT Environmental Solutions Initiative is walking the talk here. We have a project called Here in Real that leads cross-partisan conversation about climate change.

And we've made these episodes short and nonpartisan so that they're easy to share with people in your life, no matter what side of the aisle that they sit on. So please do. And we've got a whole bunch of new episodes that we'll be releasing over the next few months. So hit subscribe to get notified when they come out. And hey, we won an AVA Digital Platinum Award. Woo!
