In the aftermath of Cyclone Chido, which battered the French overseas department of Mayotte on Saturday, locals and experts told Climate Home News that the government had not done enough to prepare the island territory off the east coast of Africa for the growing threat from powerful storms.
High winds, heavy rain and huge waves contributed to a death toll which authorities fear could rise from the current count of 31 to more than 1,000 on Mayotte’s two islands where many people – particularly tens of thousands of undocumented migrants – live in “banga” slums with tin roofs.
France’s interior minister, Bruno Retailleau, said Mayotte was “totally devastated” and about 70% of the population had been severely affected. The French Red Cross said the damage was “unimaginable”.
The cyclone was the strongest to hit Mayotte in at least 90 years, according to the Météo-France weather service, whose Francois Gourand said the storm was super-charged by particularly warm Indian Ocean waters.
On top of this, experts told Climate Home News that failures to adapt to climate change had worsened the impact of the storm. “The island was so fragile,” said one local official, who did not want to be named, explaining that the buildings were too weak to withstand the winds.
Researcher Emily Wilkinson, director of ODI Global’s resilient and sustainable islands initiative, said Mayotte’s plans to get residents to safety were not good enough.
During a visit to Mayotte starting on Thursday, French President Emmanuel Macron defended the government’s response to a crowd of angry locals, saying that the territory had been prepared for the cyclone. “There were warnings. The services were there,” he insisted, adding that a lot more aid in the form of food and water was on its way.
According to Reuters, he also told reporters on Friday that France had invested heavily in Mayotte but its institutions could not keep up with the arrival of migrants.
‘Second-class citizens’
Mayotte is geographically part of the Comoros archipelago off the east African coast near Madagascar, which was under French control from the 19th century.
In 1974, the four Comoros island groupings held popular votes on whether to become independent of France. Three overwhelmingly voted yes and formed a nation called the Union of the Comoros.
But Mayotte’s people said no, becoming an overseas community and then one of France’s five overseas departments a few decades later in 2011, with its people becoming French citizens and voting in French elections.
Despite its affiliation, Mayotte has remained much poorer than the rest of France and suffers from high rates of unemployment and crime. Nonetheless, its status as part of France has attracted migrants from places like Comoros and about a third of its population is said to be from outside Mayotte, many of whom live in dilapidated buildings in slums.
Recognising that its overseas departments are at risk from cyclones made worse by climate change, the French government has a special green fund which channels money to projects like reinforcing buildings in these vulnerable regions.
As of the end of 2023, the fund had contributed €1.35m ($1.4m) towards six projects in Martinique, Guadeloupe and La Reunion but none in the other overseas departments of French Guiana or Mayotte.
The official in Mayotte, who has experience of accessing climate funds, said there is a “lack of expertise at a local level” that prevents the territory tapping such support, adding that Mayotte had not been hit by a big cyclone for 50 years “so they don’t have any premonition about this situation”.
But Samira Ben Ali, a young climate campaigner from Mayotte who lives in Paris, accused the French government of ignoring warnings from local activists and politicians and not fulfilling promises to finance adaptation on the islands.
“What is happening in Mayotte now is definitely a failure of governance from France,” she told Climate Home. “It really feels like we’re second-class citizens.”
Wilkinson said advanced economies like France are “not taking adaptation seriously” in comparison with efforts to cut planet-heating emissions because “they’re not thinking about parts of their territory which are located in more climate-sensitive regions”.
The adaptation projects that do exist are focused mainly on protecting mainland France rather than overseas territories, she said – “and that’s a real gap”.
Shut out of climate funds
As part of a developed country like France, Mayotte is not eligible to submit projects to UN climate funds like the Green Climate Fund, the Adaptation Fund or the new Fund for Responding to Loss and Damage.
“From the perspective of other vulnerable countries, they would argue that these territories should be receiving support directly from central governments of the UK, France, the Netherlands and Denmark – the EU countries with overseas territories,” Wilkinson explained.

But at a conference ODI organised in Brussels in October, she said, larger overseas territories showed interest in ratifying the Paris climate agreement “as a way of… broaching the topic and perhaps further down the line being able to become eligible for some of the climate funds”. Denmark’s overseas territory of Greenland ratified it in July.
The level of death and destruction on Mayotte also shows the need for early warning systems that go beyond just alerting residents to oncoming storms, Wilkinson said.
Ineffective warnings
Météo-France said in a statement that “the heavy loss of life occurred despite accurate and timely warnings” it provided more than 50 hours in advance, and Climate Home was told that warnings were communicated by email and on the news.
Wilkinson acknowledged this, but said not enough information had been given about what residents should do to protect themselves from a storm like that. In other parts of the world, advice is usually offered by a disaster manager employed by local authorities, who tells residents where to go to be safe and what to take with them. She pointed to Bangladesh as a country that does this well.
But Mayotte lacked evacuation centres that had been set up and checked ahead of time with clear instructions for using them, she said. “If you don’t have that system in place, then people don’t leave their homes,” she added.
Mayotte resident Fahar Abdoulhamidi told the Associated Press the island’s many undocumented migrants were particularly hesitant to go to shelters as they were scared they would be arrested and deported. Ben Ali said she was “just really saddened that they thought that”.
Asked whether local people’s feeling of abandonment by the French government would spur calls for independence, Ben Ali said those conversations would come after basic needs for food, water and shelter are met.
But Wilkinson warned “there’s a real danger that if the French government doesn’t respond with the adequate resources and attention to reconstruction” then it could spur independence protests similar to those seen in France’s Pacific overseas territory of New Caledonia triggered by proposed reforms to voting rights.
Macron has pledged to rebuild the islands’ devastated infrastructure and homes.

Wondering How to Talk About Climate Change? Take a Lesson from Bad Bunny
Sydney, Thursday 19 March 2026 — In response to escalating attacks on gas fields in the Middle East, including Israeli strikes on Iran’s giant South Pars gas field and Iranian retaliations on gas fields in Qatar and Saudi Arabia, the following lines can be attributed to Solaye Snider, Campaigner at Greenpeace Australia Pacific:
“The targeting of gas fields across the Middle East is a perilous escalation that reinforces just how vulnerable our fossil-fuelled world really is.
“Oil and gas have long been used as tools of power and coercion by authoritarian regimes. They cause climate chaos and environmental pollution and they drive conflict and war. The energy security of every nation still hooked on gas, including Australia, is under direct threat.
“For countries that are reliant on gas imports, like Sri Lanka, Pakistan and South Korea, this crisis is just getting started. It can take months to restart a gas export facility once it is shut down, meaning the shockwaves of these strikes will be felt for a long time to come.
“It is a gross and tragic injustice that while civilians are killed and lose their homes to this escalating violence, and families struggle with a tightening cost-of-living, gas giants like Woodside and Santos have seen their share prices surge on the prospect of windfall war profits.
“We must break this cycle. Transitioning to local renewable energy is the way to protect Australian households from the inherent volatility of fossil fuels like gas.”

DeBriefed 20 March 2026: Energy crisis deepens | Brazil’s new climate plan | New Zealand climate case
Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Iran war fallout continues
WORK FROM HOME: The International Energy Agency has advised its member countries to take 10 steps in response to the ongoing energy crisis fuelled by the Iran war, including reducing highway speeds and encouraging people to work from home, said the Guardian. It came after retaliatory attacks between Israel and Iran continued to destroy energy infrastructure in the Middle East, causing energy prices to soar further, said Reuters.
SUPPLY DISRUPTED: The IEA also said it is prepared to make more of its member nations’ 1.4bn-barrel oil reserves available to help ease the impacts of what it called the “biggest supply disruption in the history of the oil market”, reported Bloomberg. The outlet noted that Asian countries have been hit hardest by the shortages, caused by a “near-halt” of shipping through the Strait of Hormuz.
EU SUMMIT: The energy crisis dominated talks at an EU leaders summit on Thursday, said Politico. Arriving at the summit, Spain’s prime minister Pedro Sánchez attacked other European leaders for using the energy crisis as an excuse to “gut climate policies”, according to the EU Observer. The Financial Times said that some European leaders have asked the European Commission to overhaul its flagship emissions trading system (ETS) by summer in response to the energy crisis.
COAL BOOST: In response to the conflict, utility companies in Asia are “boosting coal-fired power generation to cut costs and safeguard energy supply”, said Reuters. UN climate change executive secretary Simon Stiell told Reuters: “If there was ever a moment to accelerate that energy transition, breaking dependencies which have shackled economies, this is the time.”
Around the world
- WINDFARM WINDFALL: The Trump administration in the US is considering a nearly $1bn settlement with TotalEnergies to cancel the French energy company’s two planned windfarms off the US east coast and have it instead invest in fossil-gas infrastructure in Texas, according to documents seen by the New York Times.
- BUSINESS CLASH: Following “clashes” with the agribusiness sector, Brazil launched its new climate plan, which calls for a 49-58% reduction in greenhouse gas emissions from 2022 levels by 2025 and includes “specific guidelines for different sectors”, reported Folha de Sao Paolo.
- SALES SLUMP: Sales of liquified petroleum gas from India’s state-run oil companies have fallen by 17% this month due to cuts in deliveries to commercial and industrial consumers “amid the widespread logistical bottlenecks triggered by the Iran war”, said the Economic Times.
- CUBAN ENERGY CRISIS: The US imposed an “effective oil blockade” on Cuba, leaving the country facing its “worst energy crisis in decades”, reported the Washington Post. Meanwhile, Chinese exports of solar panels to the island have “skyrocketed” since 2023, it added.
- RECORD HIGHS: An “unprecedented” heatwave in the western and south-western US is “shattering dozens of temperature records” and could lead to drought in California in the coming months, reported the Los Angeles Times.
- VULNERABILITY CONCERNS: Landslides that killed more than 100 people in southern Ethiopia have “renewed concerns about Ethiopia’s vulnerability to climate-related disasters”, said the Addis Standard.

Captured
Carbon Brief this week published a significant update to its map of how climate change is affecting extreme weather events around the world. The map now includes 232 new extreme weather events from studies published in 2024 and 2025. Of these events, 196 were made more severe or more likely to occur by human-driven climate change, 12 were made less severe or less likely to occur and 10 had no discernible human influence. (The remaining 14 studies were inconclusive.)

New Zealand breaks new ground on climate litigation
This week, Carbon Brief speaks to experts about a first-of-its-kind climate lawsuit in New Zealand.
Earlier this week, representatives from two environmentally focused legal advocacy groups challenged the New Zealand government’s climate-action plan in court.
The plaintiffs argued that the measures laid out in the plan are insufficient to achieve the country’s legal obligation to hold global warming to 1.5C above pre-industrial temperatures.
The case could be “influential” in shaping lawsuits and rulings around the world, one legal expert not involved in the case told Carbon Brief.
Reductions vs removals
The new case contends that there are several issues regarding the New Zealand government’s response to climate change.
One of the key arguments the plaintiffs make is that New Zealand’s second emissions reduction plan, which covers the period from 2026-30, is overreliant on the use of tree-planting to achieve its targets.
When the plan was released in December 2024, it was “immediately clear that it was a pretty lacklustre plan”, Eliza Prestidge Oldfield, senior legal researcher at the Environmental Law Initiative, one of the groups behind the legal case, told Carbon Brief.
The plan called for large-scale planting of pine tree plantations, which are not native to New Zealand and have a high risk of burning. Because of this, there are concerns about how permanent any carbon removal provided by these plantations actually can be, experts told Carbon Brief.
Catherine Higham, senior policy fellow at the Grantham Research Institute on Climate Change and the Environment who was not involved in the case, said:
“The lawyers are arguing that there are real challenges with equating the emissions that you may be able to remove from the atmosphere through afforestation with actual emissions reductions, which are much more certain.”
‘Global dialogue’
While other climate lawsuits elsewhere in the world have also focused on the inadequacy of a government’s plan to meet its stated emissions-reduction targets, this is the first such case that addresses the role of removals head-on.
Lucy Maxwell, co-director of the Climate Litigation Network, told Carbon Brief that the lawsuit “builds on a decade of climate litigation” in national, regional and international courts.
Maxwell, who was not involved in the New Zealand case, added that there is a “real global dialogue” between, not just plaintiffs, but national courts as well. She said:
“[National courts] look to common issues that have been decided in other countries. They’re not binding on that court if it’s at the national level, but they are influential.”
Given that many other countries have legal frameworks requiring their governments to create plans outlining the pathway to their long-term climate targets, Prestidge Oldfield told Carbon Brief that other jurisdictions “should be interested in these questions around the level of certainty”.
Higham noted that, even if the case is successful, addressing the plan’s shortfalls will face its own set of challenges. She told Carbon Brief:
“A lot of these decisions are political and they can be politically contentious…Those [measures] have to be put into action through legislation and that is then subject to the usual political process. So that’s where the challenge comes in.”
While she could not speculate on the outcome of the case, Prestidge Oldfield said it was “very heartening” to see that both the judge and the opposing counsel “appreciated how much of a concern climate change is globally”.
She added:
“It’s not a given that the judge would even be interested in climate change.”
