The Brief

In 1995, a leading group of scientists convened by the United Nations declared that they had detected a “human influence” on global temperatures with “effectively irreversible” consequences. In the coming decades, 99.9 percent of scientists would come to agree that burning fossil fuels had disrupted the Earth’s climate.

Yet almost 30 years after that warning, during the hottest year on Earth in 125,000 years, people are still arguing that the science is unreliable, or that the threat is real but we shouldn’t do anything about climate change. Conspiracies are thriving online, according to a report by the coalition Climate Action Against Disinformation released last month, in time for the U.N. climate conference in Dubai. Over the past year, posts with the hashtag #climatescam have gotten more likes and retweets on the platform known as X than ones with #climatecrisis or #climateemergency.

By now, anyone looking out the window can see flowers blooming earlier and lakes freezing later. Why, after all this time, do 15 percent of Americans fall for the lie that global warming isn’t happening? And is there anything that can be done to bring them around to reality? New research suggests that understanding why fake news is compelling to people can tell us something about how to defend ourselves against it.

People buy into bad information for different reasons, said Andy Norman, an author and philosopher who co-founded the Mental Immunity Project, which aims to protect people from manipulative information. Due to quirks of psychology, people can end up overlooking inconvenient facts when confronted with arguments that support their beliefs. “The more you rely on useful beliefs at the expense of true beliefs, the more unhinged your thinking becomes,” Norman said. Another reason people are drawn to conspiracies is that they feel like they’re in on a big, world-transforming secret: Flat Earthers think they’re seeing past the illusions the vast majority don’t.

The annual U.N. climate summits often coincide with a surge in misleading information on social media. As COP28 ramped up in late November, conspiracy theories circulated claiming that governments were trying to cause food shortages by seizing land from farmers, supposedly using climate change as an excuse. Spreading lies about global warming like these can further social divisions and undermine public and political support for action to reduce emissions, according to the Climate Action Against Disinformation report. It can also lead to harassment: Some 73 percent of climate scientists who regularly appear in the media have experienced online abuse.

Part of the problem is the genuine appeal of fake news. A recent study in Nature Human Behavior found that climate change disinformation was more persuasive than scientific facts. Researchers at the University of Geneva in Switzerland had originally intended to see if they could help people fend off disinformation, testing different strategies on nearly 7,000 people from 12 countries, including the United States, India, and Nigeria. Participants read a paragraph intended to strengthen their mental defenses — reminders of the scientific consensus around climate change, the trustworthiness of scientists, or the moral responsibility to act, for example. Then they were subjected to a barrage of 20 real tweets that blamed warming on the sun and the “wavy” jet stream, spouted conspiracies about “the climate hoax devised by the U.N.,” and warned that the elites “want us to eat bugs.”

The interventions didn’t work as hoped, said Tobia Spampatti, an author of the study and a neuroscience researcher at the University of Geneva. The flood of fake news — meant to simulate what people encounter in social media echo chambers — had a big effect. Reading the tweets about bogus conspiracies lowered people’s belief that climate change was happening, their support for action to reduce emissions, and their willingness to do something about it personally. The disinformation was simply more compelling than scientific facts, partly because it plays with people’s emotions, Spampatti said (eliciting anger toward elites who want you to eat bugs, for example). The only paragraph that helped people recognize falsehoods was one that prompted them to evaluate the accuracy of the information they were seeing, a nudge that brought some people back to reality.

The study attempted to use “pre-bunking,” a tactic to vaccinate people against fake news. While the effort flopped, Norman said that doesn’t mean it shows “inoculation” is ineffective. Spampatti and other researchers’ effort to fortify people’s mental defenses used a new, broader approach to pre-bunking, trying to protect against a bunch of lines of disinformation at once, that didn’t work as well as tried-and-true inoculation techniques, according to Norman.

Norman says it’s crucial that any intervention to stop the spread of disinformation comes with a “weakened dose” of it, like a vaccine, to help people understand why someone might benefit from lying. For example, when the Biden administration learned of Russia’s President Vladimir Putin’s plans to invade Ukraine in late 2021, the White House began warning the world that Russia would push a false narrative to justify the invasion, including staging a fake, graphic video of a Ukrainian attack on Russian territory. When the video came out, it was quickly dismissed as fake news. “It was a wildly successful attempt to inoculate much of the world against Putin’s preferred narrative about Ukraine,” Norman said.

For climate change, that approach might not succeed — decades of oil-funded disinformation campaigns have already infected the public. “It’s really hard to think about someone who hasn’t been exposed to climate skepticism or disinformation from fossil fuel industries,” said Emma Frances Bloomfield, a communication professor at the University of Nevada, Los Vegas. “It’s just so pervasive. They have talking heads who go on news programs, they flood media publications and the internet, they pay lobbyists.”

Bloomfield argues that disinformation sticks for a reason, and that simply telling the people who fall for it that there’s a scientific consensus isn’t enough. “They’re doubting climate change because they doubt scientific authorities,” Bloomfield said. “They’re making decisions about the environment, not based on the facts or the science, but based on their values or other things that are important to them.”

While political identity can explain some resistance to climate change, there are other reasons people dismiss the evidence, as Bloomfield outlines in her upcoming book Science v. Story: Narrative Strategies for Science Communicators. “In the climate change story, we’re the villains, or at least partially blameworthy for what’s happening to the environment, and it requires us to make a lot of sacrifices,” Bloomfield said. “That’s a hard story to adopt because of the role we’re playing within it.” Accepting climate change, to some degree, means accepting inner conflict. You always know you could do more to lower your carbon footprint, whether that’s ditching meat, refusing to fly, or wearing your old clothes until they’re threadbare and ratty.

By contrast, embracing climate denial allows people to identify as heroes, Bloomfield said. They don’t have to do anything differently, and might even see driving around in a gas-guzzling truck as part of God’s plan. It’s a comforting narrative, and certainly easier than wrestling with ethical dilemmas or existential dread.

Those seeking to amplify tensions around climate change or spread doubt, such as fossil fuel companies, social media trolls, and countries like Russia and China, get a lot of bang for their buck. “It’s a lot easier and cheaper to push doubt than to push certainty,” Bloomfield said. Oil companies including Shell, ExxonMobil, and BP spent about $4 million to $5 million on Facebook ads related to social issues and politics this year, according to the Climate Action Against Disinformation report. To sow doubt, you only need to arouse some suspicion. Creating a bullet-proof case for something is much harder — it might take thousands of scientific studies (or debunking hundreds of counterarguments one by one, as Grist did in 2006).

The most straightforward way to fight disinformation would be to stop it from happening in the first place, Spampatti said. But even if regulators were able to get social media companies to try to stop the spread of conspiracy theories and falsehoods, dislodging them is a different story. One promising approach, “deep canvassing,” seeks to persuade people through nonjudgmental, one-on-one conversations. The outreach method, invented by LGBTQ+ advocates, involves hearing people’s concerns and helping them work through their conflicted feelings. (Remember how accepting climate change means accepting you might be a tiny part of the problem?)

Research has shown that deep canvassing isn’t just successful at reducing transphobia, but also that its effects can last for months, a long time compared to other interventions. The strategy can work for other polarizing problems, too, based on one experiment in a rural metal-smelting town in British Columbia. After convincing several local governments across the West Kootenay region to shift to 100 percent renewable energy, volunteers with the nonprofit Neighbors United kept running into difficulties in the town of Trail, where they encountered distrust of environmentalists. They spoke to hundreds of residents, listening to their worries about losing jobs, finding common ground, and telling personal stories about climate change like friends would, instead of debating the facts like antagonists. A stunning 40 percent of residents shifted their beliefs, and Trail’s city council voted in 2022 to shift to 100 percent renewable energy by 2050.

Both facts and stories have a place, Bloomfield said. For conservative audiences, she suggests that climate advocates move away from talking about global systems and scientists with the Intergovernmental Panel on Climate Change — a “nameless, faceless, nebulous group of people” — and toward local matters and people they actually know. Getting information from friends, family, and other trusted individuals can really help.

“They’re not necessarily as authoritative as the IPCC,” Bloomfield said. “But it helps you connect with that information, and you trust that person, so you trust that information that they’re resharing.”

The California Science Center unveiled Tuesday the first of many launch vehicles, engines and other artifacts set to be installed in the museum’s 200,000-square-foot expansion coming to Exposition Park.

Once complete, the new Samuel Oschin Air and Space Center will include multi-level galleries built around a towering centerpiece — the space shuttle Endeavour — displayed in its 20-story vertical launch position.

It’ll be the only place in the world where visitors can see an authentic space shuttle in its “Go for Stack” position, which is what museum officials called the process of moving each of the space shuttle components into place.

Museum admission will be free.

Jeff Rudolph, president and CEO of the California Science Center, said the $450 million expansion is California’s biggest “endeavor” yet to inspire the next generation of scientists, engineers and explorers.

“The enthusiasm that people have when they come in and see this stuff and get excited about it will hopefully lead to many more people, young and old, but particularly young people wanting to pursue more education in science,” Rudolph told LAist.

Museum officials expect to announce next year an opening date, according to Rudolph.

A look inside the center

The Samuel Oschin Air and Space Center will feature three main galleries: the Samuel Oschin Shuttle Gallery, the Korean Air Aviation Gallery and the Kent Kresa Space Gallery.

Guests will be guided through hundreds of exhibits and authentic artifacts focused on the exploration of the universe — including rocket ships that carried humans into space and telescopes used to view stars and galaxies beyond our reach.

The first artifacts in the expanded museum were placed in the Kenta Kresa Space Gallery, including a three-story-tall Electron launch vehicle from Rocket Lab in Long Beach.

Adam Spice, chief financial officer of Rocket Lab, told LAist the Electron helped lower the cost of getting to space by sending satellites in smaller, cheaper rockets. The new center is an opportunity to get up close and personal with an Electron for the first time outside of a factory.

Spice said he hopes it’ll show visitors their dreams can become a reality.

“They can be part of something much bigger than probably they ever thought they could,” he said.

The first artifacts installed in the Samuel Oschin Air and Space Center include a solid rocket booster segment. Kenneth Phillips, aerospace curator, shows the scale of the piece, which has flown into space several times.

A segment of a solid rocket booster that flew into space several times is laid on its side on the second floor of the gallery.

Kenneth Phillips, the California Science Center’s aerospace curator, told LAist it’ll be turned into an interactive exhibit with audio, video and educational graphics.

“It's 12 feet in diameter, so people can actually walk through it and learn about the function of it from the inside out literally,” Phillips said.

A detailed model of a space shuttle main engine is set up next to the solid rocket booster. Three of those main engines helped boost space shuttles into orbit by providing about 20% of their power, Phillips said.

What's next

Construction of the Samuel Oschin Air and Space Center started more than three years ago and is on track to be completed in the coming weeks, according to museum officials.

With construction of the Samuel Oschin Air and Space Center weeks away from completion, crews have started to put in landscaping around the outside of the expansion.

The remaining exhibits and artifacts will then be installed over "many months," Rudolph said. Officials expect to announce next year an opening date for the expansion.

The California Science Center also is looking to raise about $70 million more for the $450 million project before it opens. You can learn more about its “EndeavourLA” fundraising campaign here.
