Deadly Asian floods are no fluke. They’re a climate warning, scientists say

HANOI, Vietnam (AP) — Southeast Asia is being pummeled by unusually severe floods this year, as late-arriving storms and relentless rains wreak havoc that has caught many places off guard.

Deaths have topped 1,400 across Indonesia, Sri Lanka, and Thailand, with more than 1,000 still missing in floods and landslides. In Indonesia, entire villages remain cut off after bridges and roads were swept away. Thousands in Sri Lanka lack clean water, while Thailand’s prime minister acknowledged shortcomings in his government's response.

Malaysia is still reeling from one its worst floods, which killed three and displaced thousands. Meanwhile, Vietnam and the Philippines have faced a year of punishing storms and floods that have left hundreds dead.

What feels unprecedented is exactly what climate scientists expect: A new normal of punishing storms, floods and devastation.

“Southeast Asia should brace for a likely continuation and potential worsening of extreme weather in 2026 and for many years immediately following that," said Jemilah Mahmood, who leads the think tank Sunway Centre for Planetary Health in Kuala Lumpur, Malaysia.

Climate patterns last year helped set the stage for 2025's extreme weather.

Atmospheric levels of heat-trapping carbon dioxide jumped by the most on record in 2024. That “turbocharged” the climate, the United Nation's World Meteorological Organization says, resulting in more extreme weather.

Asia is bearing the brunt of such changes, warming nearly twice as fast as the global average. Scientists agree that the intensity and frequency of extreme weather events are increasing.

Warmer ocean temperatures provide more energy for storms, making them stronger and wetter, while rising sea levels amplify storm surges, said Benjamin Horton, a professor of earth science at the City University of Hong Kong.

Storms are arriving later in the year, one after another as climate change affects air and ocean currents, including systems like El Nino, which keeps ocean waters warmer for longer and extends the typhoon season. With more moisture in the air and changes in wind patterns, storms can form quickly.

“While the total number of storms may not dramatically increase, their severity and unpredictability will," Horton said.

The unpredictability, intensity, and frequency of recent extreme weather events are overwhelming Southeast Asian governments, said Aslam Perwaiz of the Bangkok-based intergovernmental Asian Disaster Preparedness Center. He attributes that to a tendency to focus on responding to disasters rather than preparing for them.

“Future disasters will give us even less lead time to prepare," Perwaiz warned.

In Sri Lanka’s hardest-hit provinces, little has changed since 2004 Indian Ocean tsunami, said Sarala Emmanuel, a human-rights researcher in Batticaloa. It killed 230,000 people.

"When a disaster like this happens, the poor and marginalized communities are the worst affected,” Emmanuel said. That includes poor tea plantation workers living in areas prone to landslides.

Unregulated development that damages local ecosystems has worsened flood damage, said Sandun Thudugala of the Colombo-based non-profit Law and Society Trust. Sri Lanka needs to rethink how it builds and plans, he said, taking into account a future where extreme weather is the norm.

Videos of logs swept downstream in Indonesia suggested deforestation may have made the floods worse. Since 2000, the flood-inundated Indonesian provinces of Aceh, North Sumatra and West Sumatra have lost 19,600 square kilometers (7,569 square miles) of forest, an area larger than the state of New Jersey, according to Global Forest Watch.

Officials rejected claims of illegal logging, saying the timber looked old and probably came from landholders.

Countries are losing billions of dollars a year because of climate change.

Vietnam estimates that it lost over $3 billion in the first 11 months of this year because of floods, landslides and storms.

Thailand's government data is fragmented, but its agriculture ministry estimates about $47 million in agricultural losses since August. The Kasikorn Research Center estimates the November floods in southern Thailand alone caused about $781 million in losses, potentially shaving off 0.1% of GDP.

Indonesia doesn't have data for losses for this year but its annual average losses from natural disasters are $1.37 billion, its finance ministry says.

Costs from disasters are an added burden for Sri Lanka, which contributes a tiny fraction of global carbon emissions but is at the frontline of climate impacts, while it spends most of its wealth to repay foreign loans, said Thudugala.

"There is also an urgent need for vulnerable countries like ours to get compensated for loss and damages we suffer because of global warming,” Thudugala said.

“My request ... is support to recover some of the losses we have suffered,” said Rohan Wickramarachchi, owner of a commercial building in the central Sri Lankan town of Peradeniya that was flooded to its second floor. He and dozens of other families he knows must now start over.

Responding to increasingly desperate calls for help, at the COP30 global climate conference last month in Brazil, countries pledged to triple funding for climate adaptation and make $1.3 trillion in annual climate financing available by 2035. That’s still woefully short of what developing nations requested, and it's unclear if those funds will actually materialize.

Southeast Asia is at a crossroads for climate action, said Thomas Houlie of the science and policy institute, Climate Analytics. The region is expanding use of renewable energy but still reliant on fossil fuels.

“What we’re seeing in the region is dramatic and it’s unfortunately a stark reminder of the consequences of the climate crisis," Houlie said.

DETROIT (AP) — U.S. Rep. Haley Stevens and Abdul El-Sayed spent the final hours of Michigan's fiercely contested Democratic Senate primary making their closing pitches in settings that reflected the starkly different campaigns they have run for more than a year.

In Detroit, El-Sayed posed for photos and participated in interviews with content creators at a backyard pool party before a final rally with supporters. He projected confidence about Tuesday’s result, already looking ahead to a general election against Republican Mike Rogers.

“We have an opportunity to continue to build this movement. We got 13 weeks left to work,” El-Sayed said at his final event of the primary campaign in Detroit.

On the state’s west side, Stevens was barnstorming in the final hours with events in Muskegon Heights and Grand Rapids alongside Michigan Democratic officials. She continued to frame herself as the only candidate who could defeat Rogers.

It was a fitting final contrast in a race that has become one of the clearest tests yet of where Democratic voters want their party to go. El-Sayed, a progressive backed by Sen. Bernie Sanders and other leaders on the party’s left, has run against much of the Democratic establishment. Stevens, a four-term congresswoman backed by Senate Democratic leader Chuck Schumer and many of Michigan’s top Democrats, has made electability and experience central to her case.

Tens of millions of dollars have poured into the race, much of it from outside groups supporting Stevens. But the contest now comes down to which candidate can assemble enough of Michigan’s Democratic coalition to win Tuesday.

El-Sayed opted to focus in his campaign’s final days on Detroit, which he called a “spiritual home” and a place where he wanted to “demonstrate what this movement is and what it could mean.”

Stevens, meanwhile, spent time in Detroit before heading to the state's west side. She called the final push the “last word phenomenon."

“Everyone’s trying to get in their last points," she said.

Both candidates have spent parts of the campaign’s final days in Detroit, where Black voters have long been crucial to winning Democratic primaries.

El-Sayed began Sunday by sitting alongside his wife and Black political leaders in a packed Detroit church, clapping as the congregation sang and the pastor preached. Then he stood before the room and asked for their votes.

“I believe in the kind of America where no matter where you grow up, the color of your skin, how you pray, you deserve equal rights in this country,” El-Sayed told the congregation at Kingdom Covenant Church.

“You deserve to go to a good school, you deserve to get healthcare, you deserve to graduate and get a good job,” he added.

El-Sayed was joined by Democratic Reps. Summer Lee of Pennsylvania and Ayanna Pressley of Massachusetts, as well as Yusef Jackson, the son of the late Rev. Jesse Jackson who is president of the Rainbow PUSH Coalition.

Pastor David A. Johnson II said welcoming a political candidate was not something he typically did, but “this particular season, it’s time for us to do something different.”

For Robin Robertson, a 59-year-old Detroit resident, El-Sayed’s visit came just in time. Robertson said she had gone back and forth over whom to support, waiting until the campaign’s final days to decide.

She ultimately settled on El-Sayed, saying Stevens “had a good run.”

“His agenda seems to match more for me the things that we need right now,” Robertson said. “And then, he’s here in my little church. That was confirmation that I’m going to vote for him.”

Stevens, meanwhile, emphasized her longstanding connections to Detroit-area churches.

At a church in Pontiac on Sunday afternoon, Stevens stayed after the service to speak individually with congregants, greeting many like familiar faces.

“I come here year-round. This isn’t just a campaign thing,” Stevens said. “Our churches are places of community refuge, community connection.”

Stevens and her allies have also made a direct appeal to Black voters through advertisements highlighting her ties to former President Barack Obama and her work as chief of staff for his administration’s auto rescue effort from 2009 to 2011.

Her campaign acknowledges that a strong showing among Detroit voters will likely be necessary for her to win Tuesday.

Reggie Williams, a longtime constituent who was supporting Stevens at an Oakland County event Sunday evening in a union hall, said he continues to back her because she “has always been there for the people.”

“She is out and about in the community, always has boots on the ground,” Williams said.

After spending much of Sunday pursuing some of the same Democratic constituencies, El-Sayed and Stevens took different paths across Michigan for the final full day of the primary.

For El-Sayed, that meant leaning into a volunteer operation his campaign says has grown to 12,000 people statewide. Stevens is relying on the broader institutional support she has accumulated across the state, including endorsements from many of Michigan’s most prominent Democratic officials, such as Sen. Gary Peters and Gov. Gretchen Whitmer.

El-Sayed remained in Detroit, trying to turn enthusiasm in the state’s largest city into votes. Monday evening he closed his campaign with a voter mobilization event in Detroit, alongside other candidates running for Congress and state office.

Stevens' Monday included a stop at a soul food restaurant and bakery in Muskegon Heights, where she addressed just over 20 people and positioned herself as the only candidate who can win against Republican Mike Rogers in November.

Sharri J. Lane, who owns a jewelry business and grew up in Muskegon Heights, was in attendance and had already voted for Stevens.

“I hope that she will keep her word and will do things that will benefit so many communities like ours,” Lane, 54, said while standing next to a rack of her earrings for sale. “Sometimes we’re forgotten about, you know, after the voting ends.”

The primary has been bruising and expensive. And after Tuesday, Michigan Democrats will have to figure out how quickly they can put it behind them.

The winner will immediately face the task of bringing together supporters of two candidates who have offered different visions for the party and whose campaigns have grown increasingly contentious in the closing weeks.

El-Sayed and his allies have sharpened their attacks on Stevens. He told Semafor in July that a pro-Israel group backing her needed to “teach her how to string together two coherent sentences.” Stevens escalated her own criticism in the campaign's final days, responding to a clip of El-Sayed on July 31 by saying, “Everyone in America understands you want to blame all of your problems on Jewish Americans.”

Michigan Democrats are hoping to begin the process of coalescing almost immediately. The party plans to bring its nominees from across the state together in the days after the primary for a general election kickoff aimed at presenting a united front heading into November.
