The European climate movement is faltering. State repression has escalated. Authoritarianism is on the rise. And even though most people around the world support climate action, they consistently underestimate how much others care — giving people the sense their concern is not shared. Groups like Just Stop Oil and Climate Defiance deserve credit for keeping climate in the headlines. But any movement whose only visible face is civil disobedience will struggle to expand beyond its core.

So what could create renewed momentum?

Every day, extreme weather events are creating a new wave of climate activists, many of whom have never attended a protest or signed a petition. These are people whose homes have flooded or whose communities have been destroyed by storms or wildfires. For them, climate change isn’t abstract. Their houses are literally on fire. These communities are facing immediate crisis, and they’re in the headlines with increasing regularity. From these tragedies, there’s a window of possibility for political change.

Between 2000 and 2019, floods alone affected over 1.65 billion people globally, killing more than 100,000. Rising temperatures made last year’s Valencia floods twice as likely and 12 percent more intense. Super Typhoon Odette in the Philippines caused $800 million in damages. Vermont’s 2023 flooding resulted in $1 billion in damage claims.

For climate organizers, these events do something that years of advocacy often can’t: They make the connection between fossil fuels and real harms immediate and visceral. Recent research published in Nature found that while exposure to extreme weather alone doesn’t automatically increase support for climate policy, “subjective attribution” does. When people understand that a specific disaster was worsened by climate change and can connect it to specific corporate actors, their opinions shift.

Climate attribution science has become sophisticated enough to quantify how much a company’s emissions contributed to making a specific storm deadlier. Shell, for instance, is historically responsible for 41 billion tons of CO2 — more than 2 percent of global fossil fuel emissions. This isn’t abstract anymore. It’s evidence that can be used in courtrooms, legislative hearings and public campaigns.

This also creates a powerful economic pressure point. Climate disasters already cost insurers roughly $600 billion in losses from 2002 to 2022, yet many continue underwriting new fossil fuel projects. When disasters strike, this contradiction becomes politically untenable.

We’ve looked at three places where communities organized around extreme weather and won concrete victories — not just raising awareness or getting media traction, but tangible policy change and corporate accountability.

Vermont: Bipartisan coalition after consecutive floods

When Vermont experienced catastrophic flooding in July 2023, causing over $1 billion in damage, it came 12 years after Tropical Storm Irene, which had also caused devastation. Two such major floods galvanized an unusual coalition, which deliberately crossed party lines. The coalition’s strategy was pragmatic and studiedly nonpartisan. Environmental groups like Vermont Natural Resources Council and the Sierra Club joined forces with farmers whose fields had been destroyed and small business owners whose livelihoods were underwater. State Sen. Dick Sears framed the Climate Superfund Act around a principle everyone could understand: “The polluter pays” — those responsible for damage should pay for it.

Being bipartisan in these times is noteworthy in itself. Extreme weather events might be that rare thing that can overcome the paralyzing power of polarization and change the political arithmetic. The bill passed the Vermont Senate 21-5 and became law in May 2024 — the first of its kind in the U.S. It requires fossil fuel companies that have produced more than 1 billion metric tons of CO2 to pay their share of Vermont’s climate damages.

What made this work? Organizers centered affected communities, used climate attribution science to make connections concrete, framed the campaign around a morally-uniting principle — “polluters pay” — rather than partisan climate politics, and moved quickly while memories of flooded homes were still fresh in everyone’s minds.

When Super Typhoon Haiyan hit in 2013, killing over 6,000 people, survivors didn’t just mourn, they organized. The disaster exposed deep failures: aid arrived slowly, reconstruction stalled amid corruption, and billions in promised assistance never materialized. Protests erupted demanding accountability.

In 2015, Haiyan survivors partnered with Greenpeace Philippines to petition the Commission on Human Rights to investigate 47 fossil fuel companies for human rights violations related to climate change. This launched the world’s first investigation into corporate responsibility for climate impacts. In 2022, the commission found that fossil fuel companies could be held morally and legally responsible.

A few years later, following severe flooding in Manila, Greenpeace highlighted government failures and pointed to up to $19 billion lost to corruption since 2023. Public anger intensified, culminating in powerful protests that forced corruption and climate accountability to the top of the agenda. This surge of public pressure gave the CLIMA Bill — establishing frameworks for climate loss and damage, corporate accountability and reparations — the momentum it needed.

The decade of activism and organizing is now entering a new phase. In October 2025, 67 survivors of Super Typhoon Odette filed the first civil lawsuit directly linking a fossil fuel company to deaths in the Global South. The survivors are suing Shell in U.K. courts using attribution science showing climate change more than doubled the likelihood of the extreme event.

Survivors and NGOs need public momentum to give them the political power for legal strategies to have teeth. Crucially, over decades organizers had built the infrastructure to act when the next disaster hit.

Spain: From floods to a National Climate Emergency Pact

The Valencia floods of October 2024 killed 237 people and displaced thousands. Images of cars floating down European streets better known for their cafes shocked people worldwide. The local reaction was mass mobilization: More than 130,000 marched in Valencia, demanding accountability from officials who had delayed emergency warnings.

Organizers didn’t stop at demanding resignations; they wanted systemic change. In August 2025, following the floods and devastating summer wildfires, Prime Minister Pedro Sánchez announced a Climate Emergency Pact, which includes concrete measures such as a new State Agency for Civil Protection and Emergencies, year-round firefighting staff, and mandatory corporate carbon reporting. Billions in funding for climate adaptation infrastructure, probably the key element of any future resilience, are still “potential” and will require more grassroots pressure. 

As with Vermont, organizers used the disaster to build a coalition transcending political divisions, bringing together administrations, civil society, science, business and trade unions.

What organizers can learn

1. Act fast. When extreme weather strikes, both the media and climate skeptics move swiftly to influence the narrative. It’s crucial to be prepared. Offer direct assistance and help local community campaigns broadcast their demands.

2. Center affected communities. The most powerful voices in these stories were those of farmers who lost crops, business owners whose storefronts flooded, parents who lost children — not climate activists. These voices cut across political lines. Climate activists must step back to let authentic local voices lead.

3. Use attribution science strategically. Climate attribution research has become sophisticated enough to quantify corporate responsibility and it’s getting better and faster every year. Vermont used it to calculate damages. The Philippines case relies on it to prove Shell’s contribution. This transforms abstract climate change into concrete accountability. 

4. Use real stories as well as facts. Stories of real people, particularly first responders, cut through most effectively. When firefighters say extreme weather events are growing more frequent, people believe them.

5. Build unusual coalitions. Vermont united environmentalists with Republican farmers. Spain brought together unions and businesses. The Philippines connected survivors across multiple disasters. Diverse partnerships are stronger.

6. Make concrete demands. These campaigns identified specific villains — fossil fuel companies — and specific responses: climate superfund laws, corporate liability, emergency infrastructure. People rally around clear targets.

The path forward

Extreme weather events will keep happening, affecting more people and causing more damage and heartbreak. They’re moments of crisis and clarity when the world’s ears are more open. But they’re not without risk — in Valencia, the far-right Vox party was first on the scene, attempting to deflect the narrative away from climate. The climate movement must step in to seize the narrative.
