Climate change’s rising seas may threaten tens of millions more people than scientists and government planners originally thought because of mistaken research assumptions on how high coastal waters already are, a new study said.

Researchers studied hundreds of scientific studies and hazard assessments, calculating that about 90% of them underestimated baseline coastal water heights by an average of 1 foot (30 centimeters), according to Wednesday’s study in the journal Nature. It’s a far more frequent problem in the Global South, the Pacific and Southeast Asia, and less so in Europe and along Atlantic coasts.

The cause is a mismatch between the way sea and land altitudes are measured, said study co-author Philip Minderhoud, a hydrogeology professor at Wageningen University & Research in the Netherlands. And he attributed that to a “methodological blind spot” between the different ways those two things are measured.

Each way measures their own areas properly, he said. But where sea meets land, there’s a lot of factors that often don’t get accounted for when satellites and land-based models are used. Studies that calculate sea level rise impact usually “do not look at the actual measured sea level so they used this zero-meter” figure as a starting point, said lead author Katharina Seeger of the University of Padua in Italy. In some places in the Indo-Pacific, it’s close to 3 feet (1 meter), Minderhoud said.

One simple way to understand that is that many studies assume sea levels without waves or currents, when the reality at the water’s edge is of oceans constantly roiled by wind, tides, currents, changing temperatures and things like El Niño, said Minderhoud and Seeger.

Adjusting to a more accurate coastal height baseline means that if seas rise by a little more than 3 feet (1 meter) — as some studies suggest will happen by the end of the century — waters could inundate up to 37% more land and threaten 77 million to 132 million more people, the study said.

That would trigger problems in planning and paying for the impacts of a warming world.

People at risk

“You have a lot of people here for whom the risk of extreme flooding is much higher than people thought,’’ said Anders Levermann, a climate scientist at the Potsdam Institute for Climate Impacts Research in Germany, who wasn’t part of the study. And Southeast Asia, where the study finds the biggest discrepancy, has the most people already threatened by sea level rise, he said.

Minderhoud pointed to island nations in that region as an area where the reality of discrepancy hits home.

For 17-year-old climate activist Vepaiamele Trief, the projections aren’t abstract. On her island home in the South Pacific archipelago of Vanuatu, the shoreline has visibly retreated within her short lifetime, with beaches eroded, coastal trees uprooted and some homes now barely 3 feet (about 1 meter) from the sea at high tide. On her grandmother’s island of Ambae, a coastal road from the airport to her village has been rerouted inland because of encroaching water. Graves have been submerged and entire ways of life feel under threat.

“These studies, they aren’t just words on a paper. They aren’t just numbers. They’re people’s actual livelihoods,” she said. “Put yourself in the shoes of our coastal communities — their lives are going to be completely overturned because of sea level rise and climate change.”

Paying attention to the starting point

This new study is pretty much about what is the truth on the ground.

Calculations that may be correct for the seas overall or for the land aren’t quite right at that key intersection point of water and land, Seeger and Minderhoud said. It’s especially true in the Pacific.

“To understand how much higher a piece of land is than the water, you need to know the land elevation and the water elevation. And what this paper says the vast majority of studies have done is to just assume that zero in your land elevation dataset is the level of the water. When in fact, it’s not,” said sea level rise expert Ben Strauss, CEO of Climate Central. His 2019 study was one of the few the new paper said got it right.

“It’s just the baseline that you start from that people are getting wrong,” said Strauss, who wasn’t part of the research.

Maybe not so bad, some scientists say

Other outside scientists said that Minderhoud and Seeger may be making too much of the problem.

“I think they’re exaggerating the implications for impact studies a bit — the problem is actually well understood, albeit addressed in a way that could probably be improved,” said Gonéri Le Cozannet, a scientist at the French geological survey. Most local planners know their coastal issues and plan accordingly, Rutgers University sea level expert Robert Kopp said.

That’s true in Vietnam in the high-impact area, Minderhoud said. They have an accurate sense of elevation, he said.

The findings come as a new UNESCO report warns of major gaps in understanding how much carbon the ocean absorbs. That report said that models differ by 10% to 20% in estimating the size of that carbon sink, raising questions about the accuracy of global climate projections that rely on them.

Together, the studies suggest governments may be planning for coastal and climate risks with an incomplete picture of how the ocean is changing.

“When the ocean comes closer, it takes away more than just the land we used to enjoy,” said Thompson Natuoivi, a climate advocate for Save the Children Vanuatu.

“Sea level rise is not just changing our coastline, it’s changing our lives. We are not talking about the future — we’re talking about the right now.”

The Israeli military’s latest wave of airstrikes in Iran dealt a serious blow to the country’s brutal internal security apparatus, opening the door for a potential uprising.

During the strikes, Israel “dropped dozens of munitions on the Basij and internal security command centers that are subject to the Iranian terror regime,” the Israel Defense Forces (IDF) said in a statement on Wednesday. “The targeted command centers were used by the Iranian regime to maintain control throughout Iran and maintain the regime’s situational assessments.”

Since the start of Operation Epic Fury, the U.S. has hit nearly 2,000 targets as it carries out a sweeping military campaign aimed at dismantling the regime’s security apparatus and neutralizing threats. Adm. Brad Cooper of U.S. Central Command confirmed the number of targets hit in a video message.

The Islamic Revolutionary Guard Corps (IRGC) and the Basij militia, Iran’s volunteer paramilitary force, were behind the violent crackdown on protesters in January. The bloody crackdown saw regime actors firing on crowds and conducting mass arrests of Iranian protesters. Some had seen the protests as a sign that regime change in Iran was getting nearer, though it did not occur.

Israeli and U.S. officials have hinted at the possibility of regime change in Iran as both countries take aim at Tehran’s military and security sites.

Israeli Prime Minister Benjamin Netanyahu said in a video message announcing the launch of Operation Epic Fury, which Israel calls Operation Rising Lion, that it was time for Iranians “to rid themselves of the yoke of tyranny.” Similarly, President Donald Trump said in a message to the Iranian people on Feb. 28 that “the hour of your freedom is at hand.”

“When we are finished, take over your government. It will be yours to take. This will be, probably, your only chance for generations,” Trump said.

“America is backing you with overwhelming strength and devastating force. Now is the time to seize control of your destiny, and to unleash the prosperous and glorious future that is close within your reach. This is the moment for action. Do not let it pass,” the president added.

Ali Vaez, director of the Iran project at the International Crisis Group, told The Wall Street Journal that the path to regime change through foreign airstrikes and popular uprising on the ground has “a bet that rests on no clear historical model.” Vaez also warned that the idea “ignores the resilience of entrenched authoritarian systems like the Islamic Republic.”

The IDF said on Monday that Israel had hit headquarters, bases and regional command centers that belonged to the regime’s internal security apparatus.

“These bodies were responsible for, among other things, suppressing protests against the regime through violent measures and civilian arrests,” the IDF said.

It is unclear who will lead Iran after Supreme Leader Ayatollah Ali Khamenei was killed on the first day of the operation. Since then, Israel and the U.S. have made it clear that regime leaders chosen to replace him would be targets. Israeli Defense Minister Israel Katz warned on Wednesday that anyone chosen to replace Khamenei would be considered “a target for elimination” if they continued to threaten Israel, the U.S. and regional allies.

The killing of key leaders might not be enough to cause an uprising, as the regime has a monopoly on weapons in most of Iran, the WSJ reported, adding that Basij militants are still patrolling the streets.

Global energy markets remain in a state of high alert after several Gulf states suspended oil and gas production following escalating tensions in the region.

Since Saturday’s attacks by the United States and Israel, Tehran has targeted various sites in Israel and across several Gulf countries.

Initially, these Iranian attacks focused primarily on US military assets, but Gulf states have reported that Iran has since broadened its scope to target civilian infrastructure, including hotels, airports and energy facilities. Iranian officials have publicly denied targeting Gulf energy facilities, however.

The Middle East remains the world’s dominant source of hydrocarbon reserves and a major driver of crude oil and natural gas output.

How much oil and gas does the Middle East have?

Nearly half of the world’s oil reserves and exports come from the Middle East, which contains five of the seven largest oil reserves in the world.

Once refined, crude oil is used to make various products, including petrol, diesel, jet fuel and a wide range of household items such as cleaning products, plastics and even lotions.

After Venezuela, which has 303 billion barrels, Saudi Arabia holds the world’s second-largest proven crude oil reserves, estimated at 267 billion barrels.

The Middle East’s largest oil reserves:

• Saudi Arabia: 267 billion barrels
• Iran: 209 billion barrels
• Iraq: 145 billion barrels
• UAE: 113 billion barrels
• Kuwait: 102 billion barrels

Saudi Arabia is also the world’s top oil exporter with an estimated $187bn of crude in 2024, according to data from the Observatory of Economic Complexity (OEC).

The Middle East’s top oil exporters:

• Saudi Arabia: $187bn
• UAE: $114bn
• Iraq: $98bn
• Iran: $47bn – largely sold at a discount due to US sanctions
• Kuwait: 29bn

Other Middle Eastern countries with sizeable oil exports include: Oman ($28.9bn), Kuwait ($28.8bn) and Qatar ($21bn).

In addition to crude oil, the Middle East is a global powerhouse for natural gas, accounting for nearly 18 percent of global production and approximately 40 percent of the world’s proven reserves.

Natural gas is primarily used for electricity generation, industrial heating, and in chemicals and fertilisers.

The heart of Middle Eastern gas is a single, massive underwater reservoir called the South Pars/North Dome field. It is the largest gasfield in the world, and it is shared directly between Qatar and Iran.

Gas is transported either through pipelines or by tankers. When using pipelines, the gas is pressurised and moved through steel networks. When pipelines are not feasible, such as across oceans, Liquefied Natural Gas (LNG) is used.

To create LNG, the gas is cooled to approximately -162C (-260F), shrinking its volume and allowing it to be safely loaded onto specialised tanker ships for global transport.

To transport oil and gas, tankers from various Gulf states must navigate the narrow waterway known as the Strait of Hormuz. Approximately one-fifth of global oil and gas passes through this strait, primarily heading to major markets in Asia, including China, Japan, South Korea and India, as well as to Europe.

Which energy facilities have been attacked?

Here are the facilities which have recorded damage as of Wednesday:

Saudi Arabia – Ras Tanura oil refinery

On Monday, one of the world’s largest oil refining complexes, the Ras Tanura oil refinery owned by Saudi Aramco, was forced to halt operations after debris from intercepted Iranian drones caused a small fire.

Saudi Aramco is one of the world’s largest companies, with a market capitalisation exceeding $1.7 trillion and revenue of $480bn. Headquartered in Dhahran, in eastern Saudi Arabia, Aramco controls 12 percent of global oil production, with a capacity of more than 12 million barrels per day (bpd).

On Wednesday, Saudi defence officials reported a second drone attempt on the facility but this was successfully intercepted with no damage or disruption to operations reported.

Qatar – Ras Laffan Industrial City LNG facilities

On Monday, Qatar’s Ministry of Defence reported that Iranian drones had targeted an energy facility in Ras Laffan belonging to QatarEnergy, the world’s largest LNG producer.

While no casualties were reported, QatarEnergy suspended the production of LNG and other products at the impacted sites.

QatarEnergy’s 81 million metric tonnes of LNG exports are mostly bound for Asian markets, including China, Japan, India, South Korea, Pakistan and other countries in the region. The halt in production hiked global gas prices to a three-year high this week.

Qatar – Mesaieed Industrial City

Qatar’s Defence Ministry said the country was attacked by a second drone launched from Iran on Monday, targeting a water tank belonging to a power plant in Mesaieed, without reporting any casualties.

On Tuesday, QatarEnergy also stopped production of some downstream products like urea, polymers, methanol, aluminium and others.

UAE – Fujairah and Mussafah oil terminals

On Monday, a fire broke out at Mussafah Fuel Terminal in southwest Abu Dhabi after it was struck by a drone.

On Tuesday, falling debris from a drone interception caused a fire at the Fujairah Oil Terminal along the eastern coast of the United Arab Emirates. No injuries were reported.

Oman – ports of Duqm and Salalah

On Tuesday, multiple Iranian drones struck fuel tanks and a tanker at the port of Duqm, with at least one direct hit on a fuel storage tank, causing an explosion.

On the same day, a drone strike was recorded at the Port of Salalah, which handles fuel and industrial minerals.

Athe Nova – oil tanker

On Monday, the Athe Nova, a Honduran-flagged tanker positioned off the coast of Khor Fakkan, UAE, was struck by Iranian drones as it was transiting the Strait of Hormuz, setting it ablaze. Despite the fire, the vessel managed to exit the chokepoint into the Gulf of Oman, and no casualties were reported.

Iran’s Islamic Revolutionary Guard Corps (IRGC) claimed responsibility for the strike, identifying the Athe Nova as an “ally of the United States”.

On the same day as the attack, Iran declared the Strait of Hormuz closed, warning that any ship attempting to pass would be “set ablaze”.

Since then, several other tankers have been hit.

Other regional energy disruptions

Although not directly targeted, the following energy sites suspended operations in response to Iranian retaliatory attacks:

Israeli offshore gasfields – Major gas production fields such as Leviathan and Tamar were shut down as a precaution following regional drone and missile launches linked to Iran.

Oil fields in semiautonomous Iraqi Kurdistan – Producers including DNO, Gulf Keystone and Dana Gas halted output as a safety measure amid the escalation.

Rumaila oilfield – Operations at Iraq’s largest oilfield – operated by BP – in southern Iraq were halted on Tuesday as a security precaution due to its proximity to the escalation zone.
