Extreme weather is creating
a perfect storm of misinformation
Rumors and conspiracies are spreading too fast for emergency managers to keep up. This information chaos is slowing disaster relief and putting lives at risk.
This story is part of Distorted, a Grist series exploring the spread of misinformation in the wake of extreme weather. It is published with support from the CO2 Foundation.
You likely remember the 2023 Maui wildfires, a tragedy that killed more than 100 people and destroyed nearly 2,000 homes, all but erasing a historic island community. You may also remember that the fires began when a broken power pole owned by the local electric utility sparked against dry vegetation on a windy day.
But do you really know that? Were you there? How can you prove it?
In the aftermath of the Maui fires, thousands of people across all the major social media platforms shared posts and videos alleging that the fires had a more sinister origin. They posited that the government had used a “direct energy weapon,” or a form of laser, to ignite the area. Depending on the post you saw, this was part of a plot to reclaim the area for a high-speed rail line, or a high-tech “smart city.” A number of right-wing activists and social media personalities amplified these claims, including the late Charlie Kirk. At the same time, the Federal Emergency Management Agency saw accounts linked to China circulating rumors that a “weather weapon” had caused the fires. Other accounts alleged that the agency was going to seize the homes of people in Maui who applied for emergency aid, a claim that raised traumatic memories of colonization in a community with significant Indigenous historical and cultural ties.
Extreme weather events are always chaotic, and it’s always been easy for rumors to spread during moments of calamity, but the problem has never been as bad as it is now. The escalating pace of climate change has produced a series of supercharged wildfires, rapidly intensifying hurricanes, devastating drought, and sudden floods, all of which plunge communities into confusion and disarray. At the same time, the information landscape has never been more fragmented — major social media companies have given up on any pretense of fact-checking and content moderation; politicians often distort or politicize disasters; government agencies are short-staffed following DOGE cuts; and generative AI models have created an entirely new and little-understood way to source information. It’s not just your weird uncle seeing these rumors on Facebook: A recent report from the News Literacy Project found that a vast majority of teens encounter social media conspiracies, and a vast majority of teens who encounter those theories are inclined to believe them.
“Disasters are, by their nature, very urgent and have a lot of uncertainty surrounding them,” said Amber Silver, a professor of emergency management at the University at Albany and an expert in disaster communications. Victims of extreme weather events have an urgent need for facts, she said, but almost no way to get reliable data about their situation. “So now we have essentially all of the perfect conditions for the spread of misinformation.”

This confluence of factors does more than sow confusion. A void of good information after a disaster can lead to lost lives, traumatic displacement, or a slow recovery. It also strains the relationship between public authorities and their citizens. A growing body of research from around the world shows the consequences of this strain: A Department of Homeland Security study found that an inaccurate map tweeted out during a 2017 California flood caused an unnecessary mass evacuation, while another study, from the Inter-American Development Bank, found that an earthquake in Mexico led to an 11 percent drop in people’s trust in government. The federal government in the United States now often creates fact-checking and myth-busting websites in an attempt to dispel rumors after disasters.
A review of recent research found that this kind of bad information has often “led to resource misallocation, overwhelmed emergency services, and diverted attention away from genuine needs.”
At Grist, we have been hearing for years from emergency managers and disaster victims in the U.S. about this growing chaos. In our new series, Distorted, we’re exploring this fragmented information landscape: Who do people actually trust when disaster strikes, and why do so many people believe conspiracies that are clearly false? Is there anything the authorities can do to fight social media rumors and post-disaster hysteria What would it actually take to establish a shared sense of truth as a hurricane or a wildfire is bearing down?
The concepts of “misinformation” (unintentional deception) and “disinformation” (intentional deception) have been the subject of innumerable academic papers and policy initiatives, and the Biden administration even appointed a “disinformation governance board” at the Department of Homeland Security in 2022. In truth, the concepts are a little hard to pin down — the question of whether a certain piece of information is “dis” depends on the beliefs and attitudes of the person who’s reading or hearing that claim. Even so, it’s clear that many people believe things about disasters that simply aren’t true, and they often mistrust the people whose job it is to keep them safe.
When disaster strikes, this lack of trust can be the difference between life and death.
How a series of unrelated photos morphed into a climate conspiracy theory. SpaceX posts an Instagram photo of their Falcon 9 rocket launch from Vandenberg Space Force Base in California. A windstorm in Santiago, Chile, causes an electrical transformer to explode. A resident captures the event on video, which includes a lens flare from the bright explosion, and posts the video on TikTok. A brush fire in Maui, Hawai‘i, spreads out of control, destroying the town of Lahaina. The fires caused over $5.5 billion in damages and killed more than 100 people. Soon after the fires ignite, social media posts on Instagram, TikTok, and X start to resurface these old photos of the refinery flare, the electrical explosion, and the rocket launch, attributing them as evidence of some kind of energy weapon used to ignite the Maui fire. These posts were viewed and reshared millions of times, and often would take on a life of their own. Hawai‘i-based Instagram user @for_our_rights_kauai, for example, posted the old photo of the refinery flare and suggested the Maui fires were the result of an “attack.” A few days later, she acknowledged that the photo was unrelated to the fires. “I want to apologize for contributing to spreading that photo that I was told came from Maui on the day of this event. It turns out it was not true,” she said in a follow-up video. “It is very important for us to vet our information.” But it was too late. The instagram account @cultivateelevate, run by an influential MAHA-adjacent health food entrepreneur, had already published a video containing a screenshot of @for_our_rights_kauai’s later-deleted post. “My friend in Hawai‘i,” the host said, pointing to the screenshot, “showed a laser beam coming out of the sky, directly targeting the city.” @cultivateelevate’s video received 432,000 views, over 40 times more views than the video apologizing for the mistake. Other accounts, like Instagram user @mama_speaks_truth, also contributed to the spread, posting screenshots of screenshots of screenshots, each getting further and further from the original photo of a refinery, taken five years earlier and 4,500 miles away. This is just one example of the twisty way that misinformation can spread in the wake of a disaster. Images and facts can blend together with old fears and suspicions, morphing into a conspiracy with a new meaning and a life of its own.

It all starts with an innocuous photo taken on January 16, 2018. The Marathon Petroleum Refinery in Canton, Ohio, conducts a flare in response to a mechanical issue. A local resident captures a blurry picture of the flare, which includes a lens flare pointing upward, and posts it on Facebook. May 2018: Santa Barbara County, California
May 2023: Santiago, Chile
August 2023: Maui, Hawai‘i
Old photos become a conspiracy
The conspiracy can't be stopped
The conspiracy spreads

Experts have identified a few main vectors where communication can collapse in the lead-up and aftermath of a disaster:
Mistrust in government
The most important source of information around extreme weather is the government itself. Federal, state, and local agencies and officials are responsible for predicting the weather, sending out warnings about disasters, coordinating mandatory evacuations, and leading disaster response. If people don’t trust them, or if they can’t get their messages out effectively, lives are at stake. The background trends are already bad: Less than 20 percent of Americans say they believe the government does the right thing most of the time, the lowest level on record.
The most visible avatar of the government in a disaster is the Federal Emergency Management Agency, so it’s no coincidence that FEMA is also the most frequent subject of conspiracies and disinformation. Even though the agency is supposed to act as a backstop for state and local authorities, disaster-affected communities often swirl with allegations that federal relief is absent, that the government is restricting freedom of movement, or, as in the case of Maui, that officials are going to seize land and disenfranchise victims.
“FEMA has been the source of misinformation since its inception,” said Deanne Criswell, who led the agency under the Biden administration. She pointed to the famous allegations that the agency plans to imprison disaster victims in government-run “FEMA camps”; these allegations have circulated almost since FEMA was founded. “It’s this [idea] of the black arm of government. It makes it harder for us to actually get the assistance to the people who really need it, because they don’t know who to trust and who to believe.” There’s no knowing how many victims never show up to apply for FEMA aid because of these rumors and fears.
During Hurricane Helene in 2024, this misinformation became dangerous: A rumor about a man who had come to North Carolina to shoot FEMA disaster response officials forced Criswell to shut down field operations for several hours during the immediate aftermath of the storm. At the same time, both Criswell and her deputy chief of staff had their homes “swatted,” meaning anonymous trolls called police with false accusations that resulted in the deployment of SWAT teams. These disruptions further stressed an aid system that was already strained, which likely meant more victims in North Carolina had to wait longer to receive aid and shelter.
Hurricane Helene also hit just a few weeks before a consequential presidential election, which likely helped fuel the spread of mis- and disinformation. Right-wing accounts with names like End Wokeness accused Biden of starving North Carolina of aid, racking up millions of views despite a complete lack of evidence for their claims. Elon Musk claimed on his own platform, X, that FEMA was barring him from flying in to deliver aid, only to walk back those claims later. His retraction got 1 million views, but his initial accusation got almost 30 million, and it’s likely that many people in North Carolina and elsewhere still believe that Biden tried to restrict aid.
In other cases, mistrust in government can look very different. It doesn’t have to be about political animus — it can also be about blithe confidence, or even fear. Some people who’ve experienced storms that didn’t live up to early projections may dismiss evacuation warnings later, while others may be afraid to evacuate because they’re undocumented and fear retribution. The end result is the same — more people putting their lives at risk, and more people unwilling to get the help they need after a disaster.
“It could just be a person who says, ‘I’m a conspiracy theorist, I don’t trust the government,’ but there are also people who can’t or won’t trust that government for very different reasons,” said Silver, pointing to the example of undocumented migrants or communities that have traumatic experiences with law enforcement. “There is some skepticism and doubt, and that is hard to overcome.”
Pervasive social media
Based on the pervasiveness of social media in Americans’ lives, it may not come as a total surprise that these platforms act as the incubator for almost all major disaster conspiracy theories in the modern age. Rumors have swirled around extreme weather events since the dawn of disaster — from allegations that a group of wealthy industrialists caused the 1889 Johnstown flood, which killed more than 2,000 people in Pennsylvania, to claims that FEMA put disaster survivors in concentration camps after Hurricane Katrina. But platforms like Facebook, Instagram, and X have allowed for these rumors to achieve global circulation in minutes. The networks also make it near impossible to trace the origin or the trajectory of a given rumor, unless you’re a university or nonprofit lab doing “network analysis” of many millions of tweets.
There is little good data about how these rumors spread, but it’s clear enough that they do spread. One study on a 2023 earthquake in Turkey found that around a quarter of polled residents believed at least some version of a conspiracy theory that the U.S. had caused the earthquake with a seismic weapon or a bomb. Those who believed these theories were more likely to be supportive of the incumbent government ahead of an election that year. A comprehensive study by the Center for Countering Digital Hate found that most conspiracy posts were from verified accounts. Even benign fakes, like a famous doctored image of a shark on a flooded highway, have duped media outlets and at least one U.S. senator.
If you’ve spent any time on social media, you already know how pervasive this kind of misinformation can be. One meta study last year found that “misleading messages … often outpaced official communications, resulting in reduced trust and exacerbating anxiety, stress, and fear.” This mistrust can have real-world consequences: A study on a 2018 Japanese earthquake found that communities with low trust in government tended to evacuate even when they didn’t need to, which risked clogging up the roads for people who actually did need to flee. After the Maui fires, Criswell worried that the fear of a colonial land grab caused families who needed help to reject it.
Even though many people blame bots and malign actors for the spread of rumors, some studies have found that most people who spread false rumors believe what they are sharing. While accounts in Russia and China may have stoked outrage about the fires in Maui, it seems clear that many people who shared such misinformation believed it to be true. One prominent source of conspiracies belonged to an account called Cultivate Elevate, with over half a million followers. It’s run by a MAHA-adjacent health food entrepreneur who posted a number of videos alleging that the fires had been set on purpose through some kind of government scheme. (The owner of the account did not respond to a request for comment.)
The rise of AI
The proliferation of large language models like Gemini and ChatGPT is the latest wrinkle. About a quarter of U.S. adults now use AI chatbots daily, and searching for information is the most common usage. These models are more likely to draw on news articles and official sources than social media rumors when they answer user queries, which can cut against misinformation — if I type in “Maui directed energy weapon” into ChatGPT, it hectors me that “there is no credible evidence supporting” that theory, and even offers to debunk the actual origins of alleged images that show lasers starting the fire — but that doesn’t mean these models would always be trustworthy in an emergency.
What if a model were to scrape a news article from last week, for example, that said there’s no evacuation from a storm, but the weather had since progressed or a new event had since formed? Can I really trust the bot to give me an accurate summary of my eligibility for FEMA benefits?
Generative AI is developing so rapidly that most researchers have yet to conduct peer-reviewed studies of how it operates in the disaster space, but it’s clear that the intersection is growing. In addition to dozens of startups that purport to map flood risk or storm damage, the Red Cross has developed a chatbot named Clara that can help navigate disaster situations, and MIT has created a similar technology called Crisischat. The Trump administration’s own chatbot, America.gov, offers information on how to get FEMA assistance. When it comes to analyzing how people trust these tools and standard chatbots like Gemini, however, we are still flying blind.
“You need to learn if the information’s accurate, but then you also need to know, Do people trust it, regardless of the objective veracity?” said Anita Atwell Seate, a professor of communication and a crisis expert at the University of Maryland. “If people trust it, they’re going to act on it whether it’s accurate or not.” Seate is working with other researchers to develop a longitudinal study about how people in disaster areas use AI tools.
It’s hard to know what it would even mean to “solve” the problem of mis- and disinformation in a landscape as fragmented as the 21st century United States. There’s no way to measure the number of people who believe a false rumor, and efforts to debunk inaccurate information will always be of necessity slower and less viral than that information itself. It’s not great for politics if someone in Iowa believes that a laser started the Maui fires, but the more urgent question is how to ensure people in disaster areas have accurate information before, during, and after extreme weather events. That could make the difference between a slow recovery and a fast one, or even between life and death.
Experts in the field tend to say that the only way to fight disinformation is to establish strong communication channels beforehand, and for emergency managers to partner with people who have organic trust in their communities. Toward the end of the Biden administration, FEMA started to experiment with such efforts. The agency partnered with a Native Hawaiian FEMA employee in Maui who reassured his broader network that the government wasn’t planning to take anyone’s home. While there are still people out there in the U.S. who believe Biden set the fire with a laser, eventually most people in the vicinity of the fire did come to the agency for aid. FEMA also partnered with the Rosalynn Carter Institute for Caregivers to distribute disaster info to home health aides and caregivers, putting information in the hands of trusted messengers who would have credibility when the disaster arrives.
“From a government perspective, they’re just like, ‘They don’t know us,’” said Seate, describing the communication difficulties that she’s observed at the National Weather Service. “But they don’t have to know us, they know Jim down at the fire station and Jim, you know, rings the alarm and posted on Facebook for us.”
The tough part is this only tends to work if you lay the foundations before a disaster. Even then, it isn’t always successful — there are people out there who will choose to believe a social media hoax over a trusted weatherman, whether because it confirms their prior beliefs or just because that’s how their brain works. Fighting misinformation isn’t like swordplay, where one side wins and another side loses. It’s more like trench warfare, where emergency managers and recovery leaders have to slog to increase their share of the information environment.
“It’s at a level that we’ve never really seen before, because the systems and the silos of information have gotten so siloed and quick,” said Justin Knighten, a risk communication consultant who led FEMA’s external affairs team under President Biden during several major disasters. “When trust is low, you have a lot of work to not only build up that trust, but to also get ahead of those upcoming threats, so you’re really working at a deficit.”
