Maybe you’re reading this in a downpour. Perhaps you’re reading it because you have questions about the upcoming hurricane season. Or maybe you’re reading it because you’re one of the 150 million Americans enduring record-breaking temperatures in this week’s heat dome.
Whatever the reason, you have a question: Is this climate change?
There’s an old maxim — that, like many things, is often dubiously attributed to Mark Twain — that goes something like, “Climate is what you expect and weather is what you get.” Weather refers to the event itself, while climate refers to the trends (averaged over 30 years or more, usually) that might make such an event more or less likely.
Climate change is almost always an exacerbating factor in the case of something like a heat wave or a heat dome. In other situations, the picture is far more complicated and uncertain. It can take years to understand if and how climate change made an extreme weather event more likely, and while organizations like World Weather Attribution work hard to provide quick and accurate estimations, getting the science wrong can fuel climate skepticism and bolster deniers’ arguments. While it might be tempting to pin all extreme weather on climate change, the truth is, not all of it is.
Still, we do know a lot about how climate change influences the weather — and we’re always learning more. While this guide is far from the be-all and end-all of attribution and should be referred to with caveats, here is what we know about how climate change is shaping the extreme weather we see today.
“When you’re looking at heat extremes, there is almost always a climate change signal,” Clair Barnes, a research associate with World Weather Attribution, told me. “I don’t think there’s ever not been a climate change signal since I’ve been doing it in the last couple of years.”
As the planet warms, local temperatures respond everywhere. There are not as many complicating variables in this relationship as there are with something like drought. “With heat waves, it’s the same answer every time: It got hotter because it’s got hotter,” Barnes said.
The Intergovernmental Panel on Climate Change has found that the kind of heat waves that would have occurred once in a decade before the Industrial Revolution now occur almost three times more frequently and are 1.2 degrees Celsius (or 2.2 degrees Fahrenheit) warmer. The most extreme examples — like the 2021 heat dome over the Pacific Northwest — appear to have been possible only because of warming caused by greenhouse gas emissions. Additionally, about 37% of global heat-related deaths, which amount to tens of thousands of deaths per year, are attributable to climate change.
There have, of course, always been heat waves. But it is with high confidence that scientists say they are hotter and last longer now than they would otherwise because of climate change.
Did climate change do it? It is “virtually certain” that heat waves are more frequent and hotter than they otherwise would be because of climate change.
WWA doesn’t specifically study wildfires since they aren’t technically “weather” (though once they form, they can make their own). Instead, the organization studies the conditions that make a fire more likely. In the American West, this deadly combo usually involves high pressure, extremely dry air, and some wind.
Globally, burned areas decreased between 1998 and 2015, but that isn’t because fire-weather conditions are improving — rather, regional leaders have gotten better at things like land use and fire management. Fire weather, meanwhile, is increasing and lasting longer due to climate change. In particular, hotter temperatures — especially hotter overnight temperatures — make it more difficult to combat the fires that do ignite. (Most fires in the U.S. start due to human negligence or arson, rather than by natural causes such as lightning strikes.)
This is especially the case in California, where 10 of the state’s largest fires have occurred in the past two decades, with five in 2020 alone; a 2023 National Integrated Drought Information System-funded study further found a 320% increase in burned areas in the state between 1996 and 2021 due to contributions of human-caused climate change, with that number expected to grow in the coming decades.
On average, wildfire weather season lengthened by two weeks around the globe from 1979 to 2019. The IPCC has medium confidence in the claim that fire weather has become more probable in the U.S., Europe, Australia, and parts of Europe over the past century, and high confidence that fire weather will increase regionally due to global warming in the coming years.
Did climate change do it? Climate change has almost certainly exacerbated the heat, humidity, and drought conditions necessary for wildfires to start. The actual ignition of the fire is frequently human-caused, however, and complicating variables such as local vegetation, forest management, and land use can also muddle the picture.
Tropical cyclones are large and complicated storm systems. Ocean temperatures, the El Niño-Southern Oscillation, wind shear, barometric pressure, atmospheric moisture, the shape of the continental shelf, emergency preparedness measures, and pure luck all affect how destructive a given storm might be — when or if it makes landfall. Climate change can put a thumb on the scale, but it is far from a lone actor.
Hurricanes — the strongest manifestation of a tropical cyclone — essentially work by transferring heat from the ocean into wind energy. Because the ocean absorbs excess heat from the warming atmosphere, scientists expect to see more “major” hurricanes of Category 3 or above in the coming years.
The storms aren’t just getting more powerful, though. Because of the interaction between ocean heat and energy in a hurricane, the storms also intensify more rapidly and are “more than twice as likely to strengthen from a weak Category 1 hurricane to a major Category 3 or stronger hurricane in a 24-hour period than they were between 1970 and 1990,” according to new research published last year.
WWA says it cannot attribute the intensification of any individual storm to climate change due to relatively limited modeling so far, so the organization instead looks at how climate change may have amplified associated rainfall and storm surges. Rainfall and flooding are, in fact, more deadly than high wind speeds in hurricanes, and both are understood to be increasing because of climate change. Put simply, a warmer atmosphere can hold more water, which means worse deluges. Researchers linked extreme rainfall during Hurricanes Katrina, Maria, and Irma to climate change; Hurricane Harvey, which flooded up to 50% of the properties in Harris County, Texas, when it made landfall in 2017, had a rainfall total 15% to 38% greater than it would have been in a pre-industrial world, researchers found. Additionally, rising sea levels caused by climate change will worsen coastal flooding during such events.
However, “trends indicate no significant change in the frequency of tropical cyclones globally,” according to the IPCC. That is, there aren’t more hurricanes; the ones that form are just more likely to become major hurricanes. Scientists understand far less about what climate change means for the smaller Category 1 or 2 storms, or if it will impact the diameter of the storms that do form.
Did climate change do it? The greenhouse effect is making the atmosphere warmer, and in a warmer climate, we’d expect to see more major hurricanes of Category 3 and above. Evidence also points to hurricanes intensifying much more rapidly in today’s climate than in the past. Climate does not seem to play a role in the overall number of storms, though, and other critical factors like the path of a storm and the emergency preparedness of a given community have a significant impact on the potential loss of life but aren’t linked to a warmer atmosphere. Hurricanes are complicated events and there is still much more research to be done in understanding how exactly they’re impacted by climate change.
In the winter, your skin might feel dry, and your lips might chap; in the summer, many parts of the country feel sticky and swampy. This is simple, observable physics: Cold air holds less moisture, and warm air holds more. The “Clausius-Clapeyron” relation, as it is known, tells us that in 1 degree C warmer air, there is 7% more moisture. All that moisture has to go somewhere, so quite literally, when it rains, it pours. (That is, when and where it rains: WWA notes that “an attribution study in northern Europe found that human influence has so far had little effect on the atmospheric circulation that caused a severe rainfall event.”)
Like heat, the relationship between warm air and rainfall is well understood, which is why the IPCC is highly confident in the attributable influence of climate change on extreme rain. While it may seem confusing that both droughts and intense rainfall are symptoms of climate change, the warming atmosphere seems to increase precipitation variability, making events on the extreme margins more likely and more frequent.
Increased precipitation can have counterintuitive results, though. Rain occurring over fewer overall days due to bursts of extreme rainfall, for example, can actually worsen droughts. And while it might seem like more water in the atmosphere would mean snowier winters, that’s only true in certain places. Because it’s also warmer, snowfall is declining globally while winters are getting wetter — and as a result, probably more miserable.
But what does “more rain” really mean? Rain on its own isn’t necessarily bad, but when it overwhelms urban infrastructure or threatens roads and houses, it can quickly become deadly. Flooding, of course, is often the result of extreme rain, but “the signal in the rainfall is not necessarily correlated to the magnitude of the floods because there are other factors that turn rain into a flood,” Barnes, the research associate with WWA, told me, citing variables such as land use, water management, urban drainage, and other physical elements of a landscape.
Landslides, likewise, are caused by everything from volcanic eruptions to human construction, but rain is often a factor (climate-linked phenomena like wildfires and thawing permafrost also contribute to landslides). The IPCC writes with “high confidence” that landslides, along with floods and water availability, “have the potential to lead to severe consequences for people, infrastructure, and the economy in most mountain regions.”
Did climate change do it? More extreme rainfall is consistent with our understanding of climate change’s effects. Many other local, physical factors can compound or mitigate disasters like floods and mudslides, however.
When I spoke with Barnes, of WWA, she told me, “It’s really easy to define a heat wave. You just go, ‘It was hot.’” Droughts, not so much. For one thing, you have to define the time span you’re looking at. There are also different kinds of drought: meteorological, when there hasn’t been enough rain; hydrological, when rivers are low possibly because something else is diverting water from the natural cycle; and agricultural, when there is not enough water specifically for crops. Like flooding, many different infrastructural and physical factors go into exacerbating or even creating various kinds of droughts.
Drought as we mean it here, though, is a question of soil moisture, Barnes told me. “That’s really hard to get data on,” she said, “and we don’t necessarily understand the feedback mechanisms affecting that as well as we understand heat waves.” As recently as 2013, the IPCC had only low confidence that trends in drought could be attributed to climate change.
We have a better understanding of how drought and climate change interact now, including how higher temperatures drive evaporation and cut into snowpack, leading to less meltwater in rivers. The IPCC’s most recent report concluded that “even relatively small incremental increases in global warming (+0.5C) cause a worsening of droughts in some regions.” The IPCC also has high confidence that “more regions are affected by increases in agricultural and ecological droughts with increasing global warming.”
WWA’s attribution studies have, however, found examples of droughts that have no connection to climate change. The organization flags that it has the highest confidence in the climate affecting droughts in the Mediterranean, southern Africa, central and eastern Asia, southern Australia, and western North America and lower confidence in central and west Africa, western and central Europe, northeast South America, and New Zealand.
Did climate change do it? Maybe. Some droughts have a strong climate signal — California’s, for example. Still, researchers remain cautious about attribution for these complicated events due in part to their significant regional variability.
Tornadoes are extremely difficult to study. Compared to droughts, which can last years, tornadoes occupy a teeny tiny area and last for just a blip in time. They “wouldn’t even register” on the models WWA uses for its attribution studies, Barnes said. “It would probably look like a slightly raised average wind speed.” The IPCC, for its part, has only “low confidence” in a connection between climate change and “severe convective storms” like tornadoes, in part due to the “short length of high-quality data records.”
But we are learning more every day. This spring, researchers posited that Tornado Alley is moving east and “away from the warm season, especially the summer, and toward the cold season.” Though it’s not entirely clear why this is happening, one theory is that it relates to how climate change is affecting regional seasonality: winters and nights are becoming warmer in certain areas, and thus more conducive to tornado formation, while others are becoming too hot for storms to form during the normal season.
Did climate change do it? Researchers aren’t entirely sure but there doesn’t appear to be a correlation between tornado formation and climate change. Still, warmer temperatures potentially make certain areas more or less prone to tornadoes than they were in the past.
We say “it was a dark and stormy night” because “it was a severe convective storm” doesn’t have the same ring. But an SCS — which forms when warm, moist air rises into colder air — is the most common and most damaging weather phenomenon in the United States. You probably just call it a thunderstorm.
Severe convective storms cause many localized events that we think of as “weather,” including heavy rainfall, high winds, tornadoes, hail, thunder, and lightning. Because heat and moisture are necessary ingredients for these kinds of storms, and because the atmosphere is getting both warmer and wetter, climate models “consistently” and confidently predict an “increase in the frequency of severe thunderstorms,” the IPCC notes — but, “there is low confidence in the details of the projected increase.” Trends remain poorly studied and highly regionally dependent; in the United States, for example, there is still no evidence of a “significant increase in convective storms, and hail and severe thunderstorms.” Still, other research suggests that for every 1.8 degree F of warming, the conditions favorable to severe convective storms will increase in frequency by up to 20%.
Hail forms during severe convective storms when the hot, moist air rises to a region of the atmosphere where it is cold enough to freeze. Like thunderstorms more generally, data is fairly limited on hail, making it difficult to study long-term trends (most climate models also do not look directly at hail, studying convective storms more broadly instead). However, it’s been hypothesized that climate change could create larger and more destructive hail in the future; if thunderstorm updrafts grow stronger, as projected, then they could hold hail at freezing high altitudes for longer, allowing individual hailstones to grow larger before falling back to Earth. One study even suggested that with continued warming, there could be a 145% increase in “significant severe hail” measuring at least 2 inches in diameter — that is, a little smaller than a tennis ball.
Did climate change do it? Everything we know about thunderstorms suggests that a warmer, wetter atmosphere will mean severe convection storms become both more frequent and more intense. But there is still very little available data to track the long-term trends, so attributing any one storm to climate change would be nearly impossible.
Just as virtually all heat waves worldwide are worsened by climate change, “nearly every instance of extreme cold across the world has decreased in likelihood,” according to the WWA. While the organization has run attribution studies on “a few” heavy snowfall events, it has either found no link to climate change or has been unable to state a conclusion confidently. On the other hand, the loss of snow cover, permafrost, Arctic sea ice, and glaciers has a high-confidence link to human-caused climate change in the IPCC report.
Just because climate change makes extreme cold and snowstorms less likely does not mean they won’t happen. Research published in Nature earlier this year suggests climate change could bring more snow to certain places, as extremely cold parts of the world warm to snow-friendly temperatures, and increased precipitation from a warmer atmosphere results in more flurries. Parts of Siberia and the northern Great Plains are even experiencing a deepening snowpack.
Did climate change do it? Probably not — though there are notable exceptions.
An earthquake is usually caused by the release of energy when two tectonic plates suddenly slip past each other (though they can also be caused by fossil fuel extraction). But before you dismiss earthquakes as having no connection to climate change, there is one place where there could be a link: water.
As Emily Pontecorvo wrote for Heatmap this spring, “Changes in surface water, whether because of heavy rain, snow, or drought, could either increase or relieve stress on geologic faults, causing them to shift.” Admittedly, even if there is a relationship between climate change, water, and earthquakes, it appears to be small — so small that humans probably can’t feel any resulting quakes.
Did climate change do it? It’s highly unlikely.
Earlier this year, extreme turbulence on a Singapore-bound flight from London killed one person and injured at least 20 others. While such events remain rare — the U.S. National Transportation Safety Board recorded just 101 serious injuries caused by turbulence on millions of flights between 2013 and 2022 — extreme turbulence appears to be increasing, potentially because of climate change.
According to one study, severe turbulence is up 55% between 1979 and 2020, seemingly due to an increase in wind shear at high altitudes caused by the temperature contrast between the equator and the North Pole. (This relationship is a little bit complicated, but essentially, at higher altitudes, the temperature over the pole has been declining due to rapid Arctic temperature changes even as it’s increased at the equator; lower in the troposphere, the opposite is happening). Other studies have similarly shown that doubling the concentration of carbon dioxide in the atmosphere could increase moderate-to-severe turbulence by as much as 127%.
Data, however, is limited and fairly subjective, leading to some skepticism in the scientific community and inaccurate dismissals by climate-change deniers. As with many complex weather phenomena, our understanding of how climate change interacts with turbulence will likely grow in the coming years as the field of research develops.
Did climate change do it? Potentially in some cases, but there is still much to learn about the connection between the two.
Desertification differs from drought in that it describes a decline in soil fertility, water, and plant life to the point of total “land degradation.” (In contrast, land can become productive again after a drought.) Like other compound disasters, desertification results from natural processes, climatic conditions, and land management practices such as grazing and deforestation.
According to the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services, land degradation is “almost always” the result of these “multiple interacting causes,” and the warming climate certainly isn’t helping. Heat stress can kill off vegetation, making landscapes more prone to desertification, as well as drive aridification.
In the resulting drylands — which comprise about 46% of global land area — you can expect dust storms (also known as haboobs), and sand storms resulting from the wind kicking up loose soils. While there have always been sand storms, one study suggests that climate change is one of the critical drivers of global annual dust emissions increasing by 25% between the late 19th century and today.
However, “climate change impacts on dust and sand storm activity remain a critical gap,” writes the IPCC, and more research is desperately needed to address this. By the UN’s estimate, dust storms were associated with the deaths of 402,000 people in 2005. As many as 951 million people, mainly in South Asia, Central Asia, West Africa, and East Asia, could be vulnerable to the impacts of desertification if climate change continues.
Did climate change do it? It was potentially a factor, but we have lots more to learn.
Are locust swarms technically “weather”? Not really. But so long as we’re on the topic of weather events of Biblical proportions, locust swarms might as well be addressed, too.
And the answer may surprise you: Climate appears to be a driver of locust swarms, which threaten food security and exacerbate famines throughout Africa, the Middle East, and South Asia. Locusts prefer “arid areas punched by extreme rainfall,” according to one study that looked at the connection between swarms and climate change, and while much of that pattern is fixed in the natural El Niño–Southern Oscillation cycle, a warming climate will also “lead to widespread increases in locust outbreaks with emerging hotspots in west central Asia.” In particular, the research found that in a low-emissions scenario, locust habitat could increase by 5%, while in a high-emissions scenario, it could increase by 13% to 25% between 2065 and 2100.
Did climate change do it? It’d likely be tricky to attribute any one locust swarm to climate change, but as with many other natural phenomena, climate likely plays a compounding factor.

On China’s rare earths, Bill Gates’ nuclear dream, and Texas renewables
Current conditions: Hurricane Melissa exploded in intensity over the warm Caribbean waters and has now strengthened into a major storm, potentially slamming into Cuba, the Dominican Republic, Haiti, and Jamaica as a Category 5 in the coming days • The Northeast is bracing for a potential nor’easter, which will be followed by a plunge in temperatures of as much as 15 degrees Fahrenheit lower than average • The northern Australian town of Julia Creek saw temperatures soar as high as 106 degrees.
Exxon Mobil filed a lawsuit against California late Friday on the grounds that two landmark new climate laws violate the oil giant’s free speech rights, The New York Times reported. The two laws would require thousands of large companies doing business in the state to calculate and report the greenhouse gas pollution created by the use of their products, so-called Scope 3 emissions. “The statutes compel Exxon Mobil to trumpet California’s preferred message even though Exxon Mobil believes the speech is misleading and misguided,” Exxon complained through its lawyers. California Governor Gavin Newsom’s office said the statutes “have already been upheld in court and we continue to have confidence in them.” He condemned the lawsuit, calling it “truly shocking that one of the biggest polluters on the planet would be opposed to transparency.”
China will delay introducing export controls on rare earths, an unnamed U.S. official told the Financial Times following two days of talks in Malaysia. For years, Beijing has been ratcheting up trade restrictions on the global supply of metals its industry dominates. But this month, China slapped the harshest controls yet on rare earths. In response, stocks in rare earth mining and refining companies soared. Despite what Heatmap’s Matthew Zeitlin called the “paradox of Trump’s critical mineral crusade” to mine even as he reduced demand from electric vehicle factories, “everybody wants to invest in critical minerals startups,” Heatmap’s Katie Brigham wrote. That — as frequent readers of this newsletter will recall — includes the federal government, which under the Trump administration has been taking equity stakes in major projects as part of deals for federal funding.
The Nuclear Regulatory Commission rewarded Bill Gates’ next-generation reactor company, TerraPower, with its final environment impact statement last week. The next step in the construction permit process is a final safety evaluation that the company expects to receive by the end of this year. If everything goes according to plan, TerraPower could end up winning the race to build the nation’s first commercial reactor to use a coolant other than water, and do so at a former coal-fired plant in the country’s top coal-producing state. “The Natrium plant in Wyoming, Kemmerer Unit 1, is now the first advanced reactor technology to successfully complete an environmental impact statement for the NRC, bringing us another step closer to delivering America’s next nuclear power plant,” said TerraPower president and CEO Chris Levesque.
A judge gave New York Governor Kathy Hochul’s administration until February 6 to issue rules for its long-delayed cap-and-invest program, the Albany Times-Union reported. The government was supposed to issue the guidelines that would launch the program as early as 2024, but continuously pushed back the release. “Early outlines of New York’s cap and invest program indicate that regulators were considering a relatively low price ceiling on pollution, making it easier for companies to buy their way out of compliance with the cap,” Heatmap’s Emily Pontecorvo wrote in January.

The Texas data center boom is being powered primarily with new wind, solar, and batteries, according to new analysis by the Energy Information Administration. Since 2021, electricity demand on the independent statewide grid operated by the Electric Reliability Council of Texas has soared. Over the past year, wind, solar, and batteries have been supplying that rising demand. Utility-scale solar generated 45 terawatt-hours of electricity in the first nine months of 2025. That’s 50% more than the same period in 2024 and nearly four times more than the same period in 2021. Wind generation, meanwhile, totaled 87 terawatt-hours for the first nine months of this year, up 4% from last year and 36% since 2021. “Together,” the analysis stated, “wind and solar generation met 36% of ERCOT’s electricity demand in the first nine months of 2025.”
The question isn’t whether the flames will come — it’s when, and what it will take to recover.
In the two decades following the turn of the millennium, wildfires came within three miles of an estimated 21.8 million Americans’ homes. That number — which has no doubt grown substantially in the five years since — represents about 6% of the nation’s population, including the survivors of some of the deadliest and most destructive fires in the country’s history. But it also includes millions of stories that never made headlines.
For every Paradise, California, and Lahaina, Hawaii, there were also dozens of uneventful evacuations, in which regular people attempted to navigate the confusing jargon of government notices and warnings. Others lost their homes in fires that were too insignificant to meet the thresholds for federal aid. And there are countless others who have decided, after too many close calls, to move somewhere else.
By any metric, costly, catastrophic, and increasingly urban wildfires are on the rise. Nearly a third of the U.S. population, however, lives in a county with a high or very high risk of wildfire, including over 60% of the counties in the West. But the shape of the recovery from those disasters in the weeks and months that follow is often that of a maze, featuring heart-rending decisions and forced hands. Understanding wildfire recovery is critical, though, for when the next disaster follows — which is why we’ve set out to explore the topic in depth.
The most immediate concerns for many in the weeks following a wildfire are financial. Homeowners are still required to pay the mortgage on homes that are nothing more than piles of ash — one study by the Federal Reserve Bank of Philadelphia found that 90-day delinquencies rose 4% and prepayments rose 16% on properties that were damaged by wildfires. Because properties destroyed in fires often receive insurance settlements that are lower than the cost to fully replace their home, “households face strong incentives to apply insurance funds toward the mortgage balance instead of rebuilding, and the observed increase in prepayment represents a symptom of broader frictions in insurance markets that leave households with large financial losses in the aftermath of a natural disaster,” the researchers explain.
Indeed, many people who believed they had adequate insurance only discover after a fire that their coverage limits are lower than 75% of their home’s actual replacement costs, putting them in the category of the underinsured. Homeowners still grappling with the loss of their residence and possessions are also left to navigate reams of required paperwork to get their money, a project one fire victim likened to having a “part-time job.” It’s not uncommon for fire survivors to wait months or even years for payouts, or to find that necessary steps to rebuilding, such as asbestos testing and dead tree removals, aren’t covered. Just last week, California Governor Gavin Newsom signed a new law requiring insurers to pay at least 60% of a homeowner’s personal property coverage on a total loss without a detailed inventory, up to $350,000. The original proposal called for a 100% payout, but faced intense insurance industry blowback .
Even if your home doesn’t burn to the ground, you might be affected by the aftermath of a nearby fire. In California, a fifth of homes in the highest-risk wildfire areas have lost insurance coverage since 2019, while premiums in those same regions have increased by 42%. Insurers’ jitters have overflowedspilled over into other Western states like Washington, where there are fewer at-risk properties than in California — 16% compared to 41% — but premiums have similarly doubled in some cases due to the perceived hazardrisks.
Some experts argue that people should be priced out of the wildland-urban interface and that managed retreat will help prevent future tragedies. But as I report in my story on fire victims who’ve decided not to rebuild, that’s easier said than done. There are only three states where insured homeowners have the legal right to replace a wildfire-destroyed home by buying a new property instead of rebuilding, meaning many survivors end up shackled to a property that is likely to burn again.
The financial maze, of course, is only one aspect of recovery — the physical and mental health repercussions can also reverberate for years. A study that followed survivors of Australia’s Black Saturday bush fires in 2009, which killed over 170 people, found that five years after the disaster, a fifth of survivors still suffered from “serious mental health challenges” like post-traumatic stress disorder. In Lahaina, two years after the fire, nearly half of the children aged 10 to 17 who survived are suspected of coping with PTSD.
Federal firefighting practices continue to focus on containing fires as quickly as possible, to the detriment of less showy but possibly more effective solutions such as prescribed burns and limits on development in fire-prone areas. Some of this is due to the long history of fire suppression in the West, but it persists due to ongoing political and public pressure. Still, you can find small and promising steps forward for forest management in places like Paradise, where the recreation and park district director has scraped together funds to begin to build a buffer between an ecosystem that is meant to burn and survivors of one of the worst fires in California’s history.
In the four pieces that follow, I’ve attempted to explore the challenges of wildfire recovery in the weeks and months after the disaster itself. In doing so, I’ve spoken to firefighters, victims, researchers, and many others to learn more about what can be done to make future recoveries easier and more effective.
The bottom line, though, is that there is no way to fully prevent wildfires. We have to learn to live alongside them, and that means recovering smarter, too. It’s not the kind of glamorous work that attracts TV cameras and headlines; often, the real work of recovery occurs in the many months after the fire is extinguished. But it also might just make the difference.
Wildfire evacuation notices are notoriously confusing, and the stakes are life or death. But how to make them better is far from obvious.
How many different ways are there to say “go”? In the emergency management world, it can seem at times like there are dozens.
Does a “level 2” alert during a wildfire, for example, mean it’s time to get out? How about a “level II” alert? Most people understand that an “evacuation order” means “you better leave now,” but how is an “evacuation warning” any different? And does a text warning that “these zones should EVACUATE NOW: SIS-5111, SIS-5108, SIS-5117…” even apply to you?
As someone who covers wildfires, I’ve been baffled not only by how difficult evacuation notices can be to parse, but also by the extent to which they vary in form and content across the United States. There is no centralized place to look up evacuation information, and even trying to follow how a single fire develops can require hopping among jargon-filled fire management websites, regional Facebook pages, and emergency department X accounts — with some anxious looking-out-the-window-at-the-approaching-pillar-of-smoke mixed in.
Google and Apple Maps don’t incorporate evacuation zone data. Third-party emergency alert programs have low subscriber rates, and official government-issued Wireless Emergency Alerts, or WEAs — messages that trigger a loud tone and vibration to all enabled phones in a specific geographic region — are often delayed, faulty, or contain bad information, none of which is ideal in a scenario where people are making life-or-death decisions. The difficulty in accessing reliable information during fast-moving disasters like wildfires is especially aggravating when you consider that nearly everyone in America owns a smartphone, i.e. a portal to all the information in the world.
So why is it still so hard to learn when and where specific evacuation notices are in place, or if they even apply to you? The answer comes down to the decentralized nature of emergency management in the United States.
A downed power line sparks a fire on a day with a Red Flag Warning. A family driving nearby notices the column of smoke and calls to report it to 911. The first responders on the scene realize that the winds are fanning the flames toward a neighborhood, and the sheriff decides to issue a wildfire warning, communicating to the residents that they should be ready to leave at a moment’s notice. She radios her office — which is now fielding multiple calls asking for information about the smoke column — and asks for the one person in the office that day with training on the alert system to compose the message.
Scenarios like these are all too common. “The people who are put in the position of issuing the messages are doing 20 other things at the same time,” Jeannette Sutton, a researcher at the University at Albany’s Emergency and Risk Communication Message Testing Lab, told me. “They might have limited training and may not have had the opportunity to think about what the messages might contain — and then they’re told by an incident commander, Send this, and they’re like, Oh my God, what do I do?”
The primary way of issuing wildfire alerts is through WEAs, with 78,000 messages sent since 2012. Although partnerships between local emergency management officials, the Federal Emergency Management Agency, the Federal Communications Commission, and cellular and internet providers facilitate the technology, it’s local departments that determine the actual content of the message. Messaging limits force some departments to condense the details of complicated and evolving fire events into 90 characters or fewer. Typos, confusing wording, and jargon inevitably abound.
Emergency management teams often prefer to err on the side of sending too few messages rather than too many for fear of inducing information overload. “We’re so attached to our devices, whether it’s Instagram or Facebook or text messages, that it’s hard to separate the wheat from the chaff, so to speak — to make sure that we are getting the right information out there,” John Rabin, the vice president of disaster management at the consulting firm ICF International and a former assistant administrator at the Federal Emergency Management Agency, told me. “One of the challenges for local and state governments is how to bring [pertinent information] up and out, so that when they send those really important notifications for evacuations, they really resonate.”
But while writing an emergency alert is a bit of an art, active prose alone doesn’t ensure an effective evacuation message.
California’s Cal Fire has found success with the “Ready, Set, Go” program, designed by the International Association of Fire Chiefs, which uses an intuitive traffic light framework — “ready” is the prep work of putting together a go-bag and waiting for more news if a fire is in the vicinity, escalating to the “go” of the actual evacuation order. Parts of Washington and Oregon use similar three-tiered systems of evacuation “levels” ranging from 1 to 3. Other places, like Montana, rely on two-step “evacuation warnings” and “evacuation orders.”
Watch Duty, a website and app that surged in popularity during the Los Angeles fires earlier this year, doesn’t worry about oversharing. Most information on Watch Duty comes from volunteers, who monitor radio scanners, check wildfire cameras, and review official law enforcement announcements, then funnel the information to the organization’s small staff, who vet it before posting. Though WatchDuty volunteers and staff — many of whom are former emergency managers or fire personnel themselves — actively review and curate the information on the app, the organization still publishes far more frequent and iterative updates than most people are used to seeing and interpreting. As a result, some users and emergency managers have criticized Watch Duty for having too much information available, as a result.
The fact that Watch Duty was downloaded more than 2 million times during the L.A. fires, though, would seem to testify to the fact that people really are hungry for information in one easy-to-locate place. The app is now available in 22 states, with more than 250 volunteers working around the clock to keep wildfire information on the app up to date. John Clarke Mills, the app’s CEO and co-founder, has said he created the app out of “spite” over the fact that the government doesn’t have a better system in place for keeping people informed on wildfires.
“I’ve not known too many situations where not having information makes it better,” Katlyn Cummings, the community manager at Watch Duty, told me. But while the app’s philosophy is “rooted in transparency and trust with our users,” Cummings stressed to me that the app’s volunteers only use official and public sources of information for their updates and never include hearsay, separating it from other crowd-sourced community apps that have proved to be less than reliable.
Still, it takes an army of a dozen full-time staff and over 200 part-time volunteers, plus an obsessively orchestrated Slack channel to centralize the wildfire and evacuation updates — which might suggest why a more official version doesn’t exist yet, either from the government or a major tech company. Google Maps currently uses AI to visualize the boundaries of wildfires, but stops short of showing users the borders of local evacuation zones (though it will route you around known road closures). A spokesperson for Google also pointed me toward a feature in Maps that shares news articles, information from local authorities, and emergency numbers when users are in “the immediate vicinity” of an actively unfolding natural disaster — a kind of do-it-yourself Watch Duty. The company declined to comment on the record about why Maps specifically excludes evacuation zones. Apple did not respond to a request for comment.
There is, of course, a major caveat to the usefulness of Watch Duty.
Users of the app tend to be a self-selecting group of hyper-plugged-in digital natives who are savvy enough to download it or otherwise know to visit the website during an unfolding emergency. As Rabin, the former FEMA official, pointed out, Watch Duty users aren’t the population that first responders are most concerned about — they’re like “Boy Scouts,” he said, because they’re “always prepared.” They’re the ones who already know what’s going on. “It’s reaching the folks that aren’t paying attention that is the big challenge,” he told me.
The older adult population is the most vulnerable in cases of wildfire. Death tolls often skew disproportionately toward the elderly; of the 30 people who died in the Los Angeles fires in January, for example, all but two were over 60 or disabled, with the average age of the deceased 77, the San Francisco Chronicle reported. Part of that is because adults 65 and older are more likely to have physical impairments that make quick or unplanned evacuations challenging. Social and technological isolation are also factors — yes, almost everyone in America has a smartphone, but that includes just 80% of those 65 and older, and only 26% of the older adult population feels “very confident” using computers or smartphones. According to an extensive 2024 report on how extreme weather impacts older adults by CNA, an independent, nonprofit research organization, “Evacuation information, including orders, is not uniformly communicated in ways and via media that are accessible to older adults or those with access and functional needs.”
Sutton, the emergency warning researcher, also cautioned that more information isn’t always better. Similar to the way scary medical test results might appear in a health portal before a doctor has a chance to review them with you (and calm you down), wildfire information shared without context or interpretation from emergency management officials means the public is “making assumptions based upon what they see on Watch Duty without actually having those official messages coming from the public officials who are responsible for issuing those messages,” she said. One role of emergency managers is to translate the raw, on-the-ground information into actionable guidance. Absent that filter, panic is probable, which could lead to uncontrollable evacuation traffic or exacerbate alert fatigue. Alternatively, people might choose to opt out of future alerts or stop checking for updates.
Sutton, though she’s a strong advocate of creating standardized language for emergency alerts — “It would be wonderful if we had consistent language that was agreed upon” between departments, she told me — was ultimately skeptical of centralizing the emergency alert system under a large agency like FEMA. “The movement of wildfires is so fast, and it requires knowledge of the local communities and the local terrain as well as meteorological knowledge,” she said. “Alerts and warnings really should be local.”
The greater emphasis, Sutton stressed, should be on providing emergency managers with the training they need to communicate quickly, concisely, and effectively with the tools they already have.
The high wire act of emergency communications, though, is that while clear and regionally informed messages are critical during life-or-death situations, it also falls on residents in fire-risk areas to be ready to receive them. California first adopted the “Ready, Set, Go” framework in 2009, and it has spent an undisclosed amount of money over the years on a sustained messaging blitz to the public. (Cal Fire’s “land use planning and public education budget is estimated at $16 million, and funds things like the updated ad spots it released as recently as this August.) Still, there is evidence that even that has not been enough — and Cal Fire is the best-resourced firefighting agency in the country, setting the gold standard for an evacuation messaging campaign.
Drills and test messages are one way to bring residents up to speed, but participation is typically very low. Many communities and residents living in wildfire-risk areas continue to treat the threat with low urgency — something to get around to one day. But whether they’re coming from your local emergency management department or the White House itself, emergency notices are only as effective as the public is willing and able to heed them.
