Tropical cyclones that rapidly intensify when passing over marine heatwaves can become “supercharged”, increasing the likelihood of high economic losses, a new study finds.
Such storms also have higher rates of rainfall and higher maximum windspeeds, according to the research.
The study, published in Science Advances, looks at the economic damages caused by nearly 800 tropical cyclones that occurred around the world between 1981 and 2023.
It finds that rapidly intensifying tropical cyclones that pass near abnormally warm parts of the ocean produce nearly double – 93% – the economic damages as storms that do not, even when levels of coastal development are taken into account.
One researcher, who was not involved in the study, tells Carbon Brief that the new analysis is a “step forward in understanding how we can better refine our predictions of what might happen in the future” in an increasingly warm world.
As marine heatwaves are projected to become more frequent under future climate change, the authors say that the interactions between storms and these heatwaves “should be given greater consideration in future strategies for climate adaptation and climate preparedness”.
‘Rapid intensification’
Tropical cyclones are rapidly rotating storm systems that form over warm ocean waters, characterised by low pressure at their cores and sustained winds that can reach more than 120 kilometres per hour.
The term “tropical cyclones” encompasses hurricanes, cyclones and typhoons, which are named as such depending on which ocean basin they occur in.
When they make landfall, these storms can cause major damage. They accounted for six of the top 10 disasters between 1900 and 2024 in terms of economic loss, according to the insurance company Aon’s 2025 climate catastrophe insight report.
These economic losses are largely caused by high wind speeds, large amounts of rainfall and damaging storm surges.
Storms can become particularly dangerous through a process called “rapid intensification”.
Rapid intensification is when a storm strengthens considerably in a short period of time. It is defined as an increase in sustained wind speed of at least 30 knots (around 55 kilometres per hour) in a 24-hour period.
There are several factors that can lead to rapid intensification, including warm ocean temperatures, high humidity and low vertical “wind shear” – meaning that the wind speeds higher up in the atmosphere are very similar to the wind speeds near the surface.
Rapid intensification has become more common since the 1980s and is projected to become even more frequent in the future with continued warming. (Although there is uncertainty as to how climate change will impact the frequency of tropical cyclones, the increase in strength and intensification is more clear.)
Marine heatwaves are another type of extreme event that are becoming more frequent due to recent warming. Like their atmospheric counterparts, marine heatwaves are periods of abnormally high ocean temperatures.
Previous research has shown that these marine heatwaves can contribute to a cyclone undergoing rapid intensification. This is because the warm ocean water acts as a “fuel” for a storm, says Dr Hamed Moftakhari, an associate professor of civil engineering at the University of Alabama who was one of the authors of the new study. He explains:
“The entire strength of the tropical cyclone [depends on] how hot the [ocean] surface is. Marine heatwave means we have an abundance of hot water that is like a gas [petrol] station. As you move over that, it’s going to supercharge you.”
However, the authors say, there is no global assessment of how rapid intensification and marine heatwaves interact – or how they contribute to economic damages.
Using the International Best Track Archive for Climate Stewardship (IBTrACS) – a database of tropical cyclone paths and intensities – the researchers identify 1,600 storms that made landfall during the 1981-2023 period, out of a total of 3,464 events.
Of these 1,600 storms, they were able to match 789 individual, land-falling cyclones with economic loss data from the Emergency Events Database (EM-DAT) and other official sources.
Then, using the IBTrACS storm data and ocean-temperature data from the European Centre for Medium-Range Weather Forecasts, the researchers classify each cyclone by whether or not it underwent rapid intensification and if it passed near a recent marine heatwave event before making landfall.
The researchers find that there is a “modest” rise in the number of marine heatwave-influenced tropical cyclones globally since 1981, but with significant regional variations. In particular, they say, there are “clear” upward trends in the north Atlantic Ocean, the north Indian Ocean and the northern hemisphere basin of the eastern Pacific Ocean.
‘Storm characteristics’
The researchers find substantial differences in the characteristics of tropical cyclones that experience rapid intensification and those that do not, as well as between rapidly intensifying storms that occur with marine heatwaves and those that occur without them.
For example, tropical cyclones that do not experience rapid intensification have, on average, maximum wind speeds of around 40 knots (74km/hr), whereas storms that rapidly intensify have an average maximum wind speed of nearly 80 knots (148km/hr).
Of the rapidly intensifying storms, those that are influenced by marine heatwaves maintain higher wind speeds during the days leading up to landfall.
Although the wind speeds are very similar between the two groups once the storms make landfall, the pre-landfall difference still has an impact on a storm’s destructiveness, says Dr Soheil Radfar, a hurricane-hazard modeller at Princeton University. Radfar, who is the lead author of the new study, tells Carbon Brief:
“Hurricane damage starts days before the landfall…Four or five days before a hurricane making landfall, we expect to have high wind speeds and, because of that high wind speed, we expect to have storm surges that impact coastal communities.”
They also find that rapidly intensifying storms have higher peak rainfall than non-rapidly intensifying storms, with marine heatwave-influenced, rapidly intensifying storms exhibiting the highest average rainfall at landfall.
The charts below show the mean sustained wind speed in knots (top) and the mean rainfall in millimetres per hour (bottom) for the tropical cyclones analysed in the study in the five days leading up to and two days following a storm making landfall.
The four lines show storms that: rapidly intensified with the influence of marine heatwaves (red); those that rapidly intensified without marine heatwaves (purple); those that experienced marine heatwaves, but did not rapidly intensify (orange); and those that neither rapidly intensified nor experienced a marine heatwave (blue).
Dr Daneeja Mawren, an ocean and climate consultant at the Mauritius-based Mascarene Environmental Consulting who was not involved in the study, tells Carbon Brief that the new study “helps clarify how marine heatwaves amplify storm characteristics”, such as stronger winds and heavier rainfall. She notes that this “has not been done on a global scale before”.
However, Mawren adds that other factors not considered in the analysis can “make a huge difference” in the rapid intensification of tropical cyclones, including subsurface marine heatwaves and eddies – circular, spinning ocean currents that can trap warm water.
Dr Jonathan Lin, an atmospheric scientist at Cornell University who was also not involved in the study, tells Carbon Brief that, while the intensification found by the study “makes physical sense”, it is inherently limited by the relatively small number of storms that occur. He adds:
“There’s not that many storms, to tease out the physical mechanisms and observational data. So being able to reproduce this kind of work in a physical model would be really important.”
Economic costs
Storm intensity is not the only factor that determines how destructive a given cyclone can be – the economic damages also depend strongly on the population density and the amount of infrastructure development where a storm hits. The study explains:
“A high storm surge in a sparsely populated area may cause less economic damage than a smaller surge in a densely populated, economically important region.”
To account for the differences in development, the researchers use a type of data called “built-up volume”, from the Global Human Settlement Layer. Built-up volume is a quantity derived from satellite data and other high-resolution imagery that combines measurements of building area and average building height in a given area. This can be used as a proxy for the level of development, the authors explain.
By comparing different cyclones that impacted areas with similar built-up volumes, the researchers can analyse how rapid intensification and marine heatwaves contribute to the overall economic damages of a storm.
They find that, even when controlling for levels of coastal development, storms that pass through a marine heatwave during their rapid intensification cause 93% higher economic damages than storms that do not.
They identify 71 marine heatwave-influenced storms that cause more than $1bn (inflation-adjusted across the dataset) in damages, compared to 45 storms that cause those levels of damage without the influence of marine heatwaves.
This quantification of the cyclones’ economic impact is one of the study’s most “important contributions”, says Mawren.
The authors also note that the continued development in coastal regions may increase the likelihood of tropical cyclone damages over time.
Towards forecasting
The study notes that the increased damages caused by marine heatwave-influenced tropical cyclones, along with the projected increases in marine heatwaves, means such storms “should be given greater consideration” in planning for future climate change.
For Radfar and Moftakhari, the new study emphasises the importance of understanding the interactions between extreme events, such as tropical cyclones and marine heatwaves.
Moftakhari notes that extreme events in the future are expected to become both more intense and more complex. This becomes a problem for climate resilience because “we basically design in the future based on what we’ve observed in the past”, he says. This may lead to underestimating potential hazards, he adds.
Mawren agrees, telling Carbon Brief that, in order to “fully capture the intensification potential”, future forecasts and risk assessments must account for marine heatwaves and other ocean phenomena, such as subsurface heat.
Lin adds that the actions needed to reduce storm damages “take on the order of decades to do right”. He tells Carbon Brief:
“All these [planning] decisions have to come by understanding the future uncertainty and so this research is a step forward in understanding how we can better refine our predictions of what might happen in the future.”

DeBriefed 10 April 2026: Worst energy crisis ‘ever’ | India withdraws COP33 bid | Drag artists and climate change
Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Ceasefire causes oil price drop
CEASEFIRE SLUMP: Following the announcement on Tuesday of a two-week ceasefire agreement between Iran and the US and Israel, oil prices dropped below $96 per barrel, according to the Associated Press. However, price volatility resumed when a Saudi Arabian oil pipeline was hit just hours later, according to Reuters.
CRISIS COMBINED: Reuters and other outlets covered comments made by the International Energy Agency’s Fatih Birol to Le Figaro, where he said that the current energy crisis is worse than those of “1973, 1979 and 2022 combined”. It added that Birol said the “world has never experienced a disruption to energy supply of such magnitude”.
POLLUTERS PROFIT: The Guardian covered how the “worst polluters hold [the] world’s future in their hands as they benefit from higher fossil fuel prices”, but it added “global trends favour renewables”. The South China Morning Post reported that, according to experts, the diversification of energy sources is set to accelerate as the war continues to disrupt the world’s energy supplies.
Around the world
- CLIMATE GOALS PERIL: The UK opening new oil and gas fields in the North Sea “would imperil” international climate goals, experts told the Guardian. The warning came as the government pushed back against the speculation that it is set to approve new drilling projects, according to Sky News.
- COP33 CHANGES: The Indian government has withdrawn its offer to host the COP33 climate summit, “following a review of its commitments for the year 2028”, reported Climate Home News.
- ‘LONG-LASTING’ SHOCK: The Financial Times covered comments by EU energy commissioner Dan Jørgensen that the bloc was bracing for a “long-lasting” energy shock from the Iran war. Reuters reported that five EU countries have called for a windfall tax on energy companies’ profits in response to rising fuel prices.
- US BUDGET CUTS: US president Donald Trump’s 2027 budget proposal included targeting the “green new scam” with substantial cuts to energy and environment programmes, according to the Los Angeles Times.
- AFGHAN FLOODS: Since 26 March, at least 148 people have died and 216 have been injured due to heavy rains, floods, earthquakes and landslides in Afghanistan, reported Reuters.
- PENGUINS ENDANGERED: The “mass drowning” of emperor penguin chicks as sea ice melts due to climate change has led the International Union for Conservation of Nature to declare the species officially in danger of extinction, according to the Guardian.

Captured
Carbon Brief analysis found that, since the beginning of the Iran war in late February, at least 60 countries have announced nearly 200 emergency energy-saving measures. Around 30 nations, from Norway to Zambia, have cut fuel taxes to help people struggling with rising costs, making this by far the most common domestic policy response to the crisis, said the analysis. Some countries have stressed the need to boost domestic renewable-energy construction, while others – including Japan, Italy and South Korea – have opted to lean more on coal, at least in the short term.

How drag is tackling climate change
This week, Carbon Brief looks at how some drag artists are using their performances to draw attention to climate change
Back in 2005, veteran climate journalist Bill McKibben wrote that “what the warming world needs now is art, sweet art” to help “build a general consciousness about climate change”.
Since then, the topic of climate change has spread to a host of art forms, from literature and music through to comedy and film.
One of the most recent art forms to take up the climate communication baton is drag, with performers using it as a “Trojan horse” to engage with audiences, according to Cheddar Gorgeous, a British drag performer.
‘Joy inspires momentum’
Drag artists around the world have begun to draw attention to the climate movement, using creativity, entertainment and their platforms to engage with their audiences.
In the UK, Cheddar Gorgeous declined a nomination for the British LGBT Awards due to its sponsorship by Shell and has made repeated calls for climate action.
Speaking on the “climate quickie” TEDx podcast, she argued:
“Drag can disrupt the master narratives that dictate our society. I love drag that makes you look at yourself and look at the world in a different way. And that can be deployed in all sorts of exciting ways.”
Drag has a proud history of disruption. As part of a TED talk titled, “Why joy is a serious way to take action”, US drag queen Pattie Gonia provided the audience with some “herstory” about the role of drag within protests. She said:
“Since the birth of the queer rights movement, drag performers and trans people have always been on the forefront of organising and protesting and community building.
“When we had the statistics and the facts on the millions of queer people dying of AIDS, yet no one was joining our fight, drag performers turned pain into joy and, in doing so, welcomed millions more people to fight with us.”
Pattie Gonia is arguably the best-known drag artist to engage with climate change. She is currently touring her environmental drag show “SAVE HER!” and has, according to her website, fundraised more than “$4.7m for LGBTQIA+, BIPOC and environmental non-profits”.
A key part of her message is the need for diversity and inclusion within the climate movement, adding that “our creativity is critical in this climate dilemma”. In her TED talk, she added:
“The problem in the climate movement isn’t just the abundance of carbon; it is the lack of joy. The scientific facts, the doom and gloom, they scare people, they wake them up. But joy is what will get people out of bed every day to take more action.”
Alongside Pattie Gonia, climate conversations are filtering into the wider drag movement, including being a topic repeatedly touched on in the highly successful TV drag contest, RuPaul’s Drag Race.
This ranges from drag artist Asia O’Hara explaining what global warming is in season 10 – telling her fellow contestants: “Bitch, the ice is melting!” – to queens dancing to “97% of scientists and four out of four Drag Race judges agree” that climate change “is real” during a challenge in season 11. (Drag Race host RuPaul Andre Charles has faced criticism for reportedly allowing fracking on his Wyoming ranch.)
Drag is opening up the climate movement to a wider audience, promoting diversity, inclusion and creativity in the space, according to its advocates. For Pattie Gonia, a key part of climate action has to be joy, she added:
“Joy provides an unbelievable opportunity to make the climate movement irresistible. Do not underestimate the power of joy. We deserve more than doom and gloom, because this is the only planet with a Beyoncé on it.”
Watch, read, listen
COOPERATION OVER CHAOS: In the Indian Express, Simon Stiell, the executive secretary of UN Climate Change, argued that “climate cooperation offers a way out of energy price chaos”.
ELECTRIC WORLD ORDER: On the Polycrisis podcast, Mark Blyth, a professor of international economics at Brown University, and Dr Naa Adjekai Adjei, a non-resident fellow, Africa, at the China Global South Project, discussed “what the US dollar has to do” with energy access in Africa.
‘THE RECKONING’: In the Equator, Mona Ali, associate professor of economics at the State University of New York, explored the closure of the Strait of Hormuz and the “end of American hegemony”.
