When deadly floods swept through Texas during the July 4th weekend of 2025, families searched for help and answers. But instead of facts, many found dangerous lies online — like claims that the government had used “weather weapons” to cause the disaster.

It sounds far-fetched, but these ideas aren’t just fringe conspiracy theories anymore. They’re reaching millions of people, right when those people need trustworthy information the most. In moments when accurate updates can save lives, false claims on social media can confuse, scare, and even cause harm — and that’s exactly what’s happening on platforms like X, YouTube, and Facebook.

What’s Happening?

A new report from the Center for Countering Digital Hate (CCDH) found that false claims about disasters like floods, wildfires, and hurricanes are spreading quickly across social media. The researchers reviewed 300 of the most-liked misleading posts from April 2023 to April 2025.

Here’s what they discovered:

  • These posts gained over 221 million views.

  • Nearly all went unlabeled and unchallenged — no fact-checks, no warnings, no corrections.

  • Some of the most extreme lies — like the idea that natural disasters were caused by “weather weapons” — were given huge platforms, even after real tragedies.

One of the most troubling examples came from conspiracy theorist Alex Jones, who claimed the Texas floods were caused by government interference. His posts weren’t hidden or flagged. They were amplified.

Who’s Behind It?

It turns out that many of these misleading posts came from verified users. On Twitter, that blue checkmark, once meant to help people spot reliable voices, is now, on X, being sold and used by those spreading misinformation.

  • 88% of the false posts on X came from verified users.
  • 73% on YouTube, and 64% on Meta (Facebook and Instagram).

One of the most high-profile figures in the study is Alex Jones, a far-right media personality and conspiracy theorist best known for his website InfoWars. Jones has promoted numerous false claims over the years — including that the 2012 Sandy Hook school shooting was a hoax. For these and other violations of platform policies on hate speech, harassment, and misinformation, he was banned from Facebook, Instagram, YouTube, and Twitter between 2018 and 2020.

However, Jones returned to X (formerly Twitter) after the platform reinstated several previously banned accounts in 2023. During the LA wildfires in 2025, Jones used his X account to spread false claims that FEMA was confiscating food and that the fires were part of a “globalist plot.” His wildfire-related posts received over 408 million views — more than FEMA and 10 major news outlets combined during that period.

Even when banned users like Jones couldn’t post directly on some platforms, their false messages lived on. Others reposted their claims or created content that echoed their talking points. On YouTube, for example, 1 in 3 misleading videos led to more misleading videos through the “Up Next” panel.

Why It’s Dangerous

It’s easy to think, “People won’t believe that stuff.” But the truth is, misinformation can cause real harm — especially during emergencies.

  • Some victims avoid seeking aid, believing false claims that disaster relief is only given to certain groups.

  • First responders have been threatened after lies spread about their efforts.

  • A man in Oklahoma vandalized a weather radar system, thinking it was part of a weather-control conspiracy.

And the consequences don’t stop there. A cloud seeding company received over 100 death threats due to false claims linking it to the floods.

How Big Is the Problem?

The reach of misinformation is staggering.

  • Alex Jones’ posts about the LA wildfires alone received 408 million views on X. That’s more than FEMA and 10 major news outlets combined during the same period.

  • In the week following the Texas floods, false posts blaming cloud seeding or climate hoaxes racked up 8.4 million views — without a single fact-check.

These lies are spreading faster than the truth. That’s a big problem.

What Needs to Change

We need to expect more from social media platforms. Here’s what the CCDH report found:

  • Less than 2% of false posts were labeled or fact-checked.

  • Platforms are still profiting — through ads, subscriptions, and increased engagement — even when the content is dangerous.

That means the current system rewards outrage and falsehoods, not truth. And when disaster strikes, that business model puts people at risk.

What You Can Do

We don’t need to wait for platforms to act. Each of us has a role to play in slowing the spread of dangerous misinformation.

Here are a few simple actions we can take:

  • Follow trusted sources like FEMA, your local emergency services, and reliable news outlets.

  • Think before sharing: If something sounds too wild to be true, double-check it first.

  • Report harmful posts that spread misinformation during emergencies.

Collectively, taking these small steps helps us help our communities stay informed and safe.

Summing Up

The next hurricane, wildfire, or flood isn’t a matter of if — it’s when. And in those crucial hours, the difference between truth and lies could mean life or death.

That’s why it’s so important to demand better from platforms — and do our part to protect each other. Let’s make sure the next time disaster strikes, facts come first.

A Disaster Unfolds

Imagine waking up in the middle of the night to a roaring wall of water crashing through your town. That’s what happened in Sikkim, India, on October 3, 2023. A glacial lake high in the Himalayas burst suddenly, sending a flood of 50 million cubic meters of water rushing downstream. Villages were washed away, bridges collapsed, and a massive hydropower dam was completely destroyed.

The flood traveled 385 kilometers, even reaching parts of Bangladesh. This was no ordinary flood—it was a Glacial Lake Outburst Flood (GLOF), a type of disaster that’s becoming more frequent as the planet warms.

What Caused the Flood?

At the heart of this disaster was South Lhonak Lake, one of the fastest-growing glacial lakes in the Himalayas. Scientists have been watching it for years, warning that its natural dam—made of ice and rock—was getting weaker.

Then, the worst happened:

  • A 14.7-million cubic meter chunk of frozen land collapsed into the lake.
  • This triggered a 20-meter-high wave—as tall as a six-story building.
  • The wave smashed through the natural dam, sending a torrent of water and debris barreling down the valley.

Think of it like a bathtub overflowing, except instead of a few gallons of water, it was millions of tons rushing out all at once.

The Impact: Lives, Land, and Infrastructure Lost

The destruction was swift and brutal:

  • 55 people lost their lives, and 74 are still missing.
  • More than 7,000 people were displaced, their homes and villages washed away.
  • 31 bridges, 25,900 buildings, and 276 square kilometers of farmland were destroyed.
  • The flood carried away 270 million cubic meters of sediment—enough to fill 100,000 Olympic-sized swimming pools.

Entire communities were left without power, food, or clean water, and the road to recovery is long.

The Role of Climate Change

So, why did this happen? The simple answer: climate change.

  • The South Lhonak Glacier has been melting faster than ever, losing 0.58 meters of ice every year.
  • The lake it feeds has grown dramatically in the past few decades.
  • Warming permafrost (frozen soil) is making mountain slopes unstable, increasing the risk of landslides and dam failures.

This isn’t just a Sikkim problem—glaciers around the world are melting at record speeds, putting millions of people at risk.

Could This Happen Again?

Unfortunately, yes. Scientists warn that South Lhonak Lake is still unstable.

  • The natural dam is eroding, making another flood likely.
  • Riverbanks weakened by the last flood could collapse, leading to more destruction.
  • Extreme rainfall—which is increasing due to climate change—could trigger another disaster.

And it’s not just Sikkim—other glacier-fed lakes in the Himalayas, the Andes, and even North America are showing similar warning signs.

Why This Matters

If you think this is just a distant problem, think again. The same climate forces that caused the Sikkim flood are also affecting other mountainous regions worldwide.

Melting Glaciers Are a Global Issue

Glaciers are retreating in Alaska, the Rocky Mountains, and the Pacific Northwest. As ice melts at a faster rate, more glacial lakes are forming, increasing the chances of floods like the one in Sikkim. If we don’t prepare, communities in mountainous regions of the U.S. could face similar disasters.

U.S. Disasters Are Increasing

The 2022 Yellowstone flood destroyed roads, bridges, and homes, forcing many residents to evacuate. In California, record-breaking storms and floods are becoming more frequent, causing billions in damage. Extreme weather events—whether floods, hurricanes, or wildfires—are getting stronger, deadlier, and harder to predict.

Our Infrastructure Is at Risk

Just like the Teesta-III dam in Sikkim collapsed, many worldwide dams, roads, and power plants are vulnerable to extreme weather. Many of these structures were built decades ago and weren’t designed to handle the kinds of disasters we’re seeing today.

We Can Learn

By taking action now, the U.S. can prevent similar disasters:

  • Invest in early warning systems—monitor unstable lakes and glaciers.
  • Upgrade infrastructure—build flood-resistant bridges and roads.
  • Plan for extreme weather—ensure communities are prepared for disasters.

Preventing Another Tragedy

While we can’t stop glaciers from melting overnight, we can take steps to reduce the damage.

Early Warning Systems (EWS)

Science and technology give us powerful tools to predict disasters before they happen. Governments and scientists must monitor unstable lakes and glaciers using satellites, sensors, and AI-driven models. These systems can detect early signs of danger, giving communities valuable time to evacuate before disaster strikes. Investing in real-time alerts and community education could save thousands of lives.

Building Stronger Infrastructure

We need to rethink how we design bridges, roads, and power plants. Structures built decades ago were not designed to handle the kinds of extreme weather we’re facing today. Engineers and policymakers must ensure that new infrastructure is flood-resistant and that existing structures are reinforced to withstand future disasters. This kind of investment is expensive, but the cost of doing nothing is far greater.

Preparing for Disasters

Education and preparation can mean the difference between life and death. Governments and communities must train people on emergency evacuation plans and improve international cooperation to respond to climate disasters. Since floods and other extreme weather events are increasing, being prepared is no longer optional—it’s essential.

Addressing Climate Change at Its Root

At the core of these disasters is a warming planet. To slow down glacial melting, we need to cut greenhouse gas emissions. Governments, businesses, and individuals can all play a role by switching to clean energy sources, reducing waste, and advocating for policies that combat climate change. These actions will protect glaciers, and help stabilize global weather patterns.

A Wake-Up Call

The Sikkim flood wasn’t just a freak event—it was a preview of what’s to come if we don’t act now. The good news? We still have time to prepare. By investing in early warning systems, better infrastructure, and climate solutions, we can reduce the risk of future disasters—both in the Himalayas and here at home.

In an era where climate change is increasingly influencing financial stability, a new study sheds light on how extreme weather events like heavy rains and tropical cyclones affect mortgage defaults and prepayments. This topic, first brought into focus by Mark Carney, former Governor of the Bank of England, has been a growing concern among financial regulators worldwide.

Weather Extremes and Mortgage Risks

The study, conducted in Florida, involved analyzing a massive dataset of 69,046 loans, amounting to over 3.7 million loan-month observations. Florida, known for its vulnerability to hurricanes and floods, serves as an ideal case for this study. The researchers used an innovative Cox proportional hazard model, incorporating spatiotemporal characteristics and weather variables, to examine the influence of weather extremes on mortgage risks.

Key Findings

  • Impact of Tropical Cyclones: The study reveals a significant, non-linear relationship between the intensity of tropical cyclones and mortgage defaults. The risk of default escalates notably with the increase in hurricane categories, especially moving from category two to three.
  • Heavy Rains and Flood Risks: Heavy rainfall in flood-prone areas also shows a substantial impact on default risks. Interestingly, such conditions discourage prepayment of mortgages, as borrowers may prefer to retain the option to default if insurance fails to cover disaster damages.
  • Climate Change Projections: By employing the First Street flood model projections for 2050, the study anticipates a systematic increase in mortgage risks due to climate change. This increase varies based on different scenarios of extreme weather events.

The findings of this study underscore the importance of integrating climate-related risks into mortgage risk assessment. As the world grapples with the impacts of climate change, this research provides valuable insights for risk managers and financial institutions to better prepare for and mitigate these emerging risks. The study not only confirms previous beliefs about the impact of weather extremes on mortgages but also offers precise quantification of these effects, emphasizing the need for climate-adjusted credit risk assessment in the face of changing environmental conditions.
