Climate change could lead to half a million more deaths from malaria in Africa over the next 25 years, according to new research.
The study, published in Nature, finds that extreme weather, rising temperatures and shifting rainfall patterns could result in an additional 123m cases of malaria across Africa – even if current climate pledges are met.
The authors explain that as the climate warms, “disruptive” weather extremes, such as flooding, will worsen across much of Africa, causing widespread interruptions to malaria treatment programmes and damage to housing.
These disruptions will account for 79% of the increased malaria transmission risk and 93% of additional deaths from the disease, according to the study.
The rest of the rise in malaria cases over the next 25 years is due to rising temperatures and shifting rainfall patterns, which will change the habitable range for the mosquitoes that carry the disease, the paper says.
The majority of new cases will occur in areas already suitable for malaria, rather than in new regions, according to the paper.
The study authors tell Carbon Brief that current literature on climate change and malaria “often overlooks how heavily malaria risk in Africa is today shaped by climate-fragile prevention and treatment systems”.
The research shows the importance of ensuring that malaria control and primary healthcare is “resilient” to the extreme weather, they say.
Malaria in a warming world
Malaria kills hundreds of thousands of people every year. The World Health Organization (WHO) estimates that 610,000 people died due to the disease in 2024.
In 2024, Africa was home to 95% of malaria cases and deaths. Children under the age of five made up three-quarters of all African malaria deaths.
The disease is transmitted to humans by bites from mosquitoes infected with the malaria parasite. The insects thrive in high temperatures of around 29C and need stagnant or slow-moving water in which to lay their eggs. As such, the areas where malaria can be transmitted are heavily dependent on the climate.
There is a wide body of research exploring the links between climate change and malaria transmission. Studies routinely find that as temperatures rise and rainfall patterns shift, the area of suitable land for malaria transmission is expanding across much of the world.
Study authors Prof Peter Gething and Prof Tasmin Symons are researchers at the Curtin University’s school of population health and the Malaria Atlas Project from the The Kids Research Institute, Australia.
They tell Carbon Brief that this approach does not capture the full picture, arguing that current literature on climate change and malaria “often overlooks how heavily malaria risk in Africa is today shaped by climate-fragile prevention and treatment systems”.
The paper notes that extreme weather events are regularly linked to surges in malaria cases across Africa and Asia. This is, in-part, because storms, heavy rainfall and floods leave pools of standing water where mosquitoes can breed. For example, nearly 15,000 cases of malaria were reported in the aftermath of Cyclone Idai hitting Mozambique in 2019.
However, the study authors also note that weather extremes often cause widespread disruption, which can limit access to healthcare, damage housing or disrupt preventative measures such as mosquito nets. These factors can all increase vulnerability to malaria, driving the spread of the disease.
In their study, the authors assess both the “ecological” effects of climate change – the impacts of temperature and rainfall changes on mosquito populations – and the “disruptive” effects of extreme weather.
Mosquito habitat
To assess the ecological impacts of climate change, the authors first identify how temperature, rainfall and humidity affect mosquito lifecycles and habitats.
The authors combine observational data on temperature, humidity and rainfall, collected over 2000-22, with a range of datasets, including mosquito abundance and breeding habitat.
The authors then use malaria infection prevalence data, collected by the Malaria Atlas Project, which describes the levels of infection in children aged between two and 10 years old.
Symons and Gething explain that they can then use “sophisticated mathematical models” to convert infection prevalence data into estimates of malaria cases.
Comparing these datasets gives the authors a baseline, showing how changes in climate have affected the range of mosquitoes and malaria rates across Africa in the early 21st century.
The authors then use global climate models to model future changes over 2024-49 under the SSP2-4.5 emissions pathway – which the authors describe as “broadly consistent with current international pledges on reduced greenhouse gas emissions”.
The authors also ran a “counterfactual” scenario, in which global temperatures do not increase over the next 25 years. By comparing malaria prevalence in their scenarios with and without climate change, the authors could identify how many malaria cases were due to climate change alone.
Overall, the ecological impacts of climate change will result in only a 0.12% increase in malaria cases by the year 2050, relative to present-day levels, according to the paper.
However, the authors say that this “minimal overall change” in Africa’s malaria rates “masks extensive geographical variation”, with some areas seeing a significant increase in malaria rates and others seeing a decrease.
Disruptive extremes
In contrast, the study estimates that 79% of the future increase in malaria transmission will be due to the “disruptive” impacts of more frequent and severe weather extremes.
The authors explain that extreme weather events, such as flooding and cyclones, can cause extensive damage to housing, leaving people without crucial protective equipment such as mosquito nets.
It can also destroy other key infrastructure, such as roads or hospitals, preventing people from accessing healthcare. This means that in the aftermath of an extreme weather event, people face a greater risk of being infected with malaria.
The climate models run by the study authors project an increase in “disruptive” extreme weather events over the next 25 years.
For example, the authors find that by the middle of the century, cyclones forming in the Indian Ocean will become more intense, with fewer category 1 to category 4 events, but more frequent category 5 events. They also find that climate change will drive an increase in flooding across Africa.
The study finds that without mitigation measures, these disruptive events will drive up the risk of malaria – especially in “main river systems” and the “cyclone-prone coastal regions of south-east Africa”.
Between 2024 and 2050, 67% of people in Africa will see their risk of catching malaria increase as a result of climate change, the study estimates.
The map below shows the percentage change in malaria transmission rate in the 2040s due to the disruptive impacts of climate change alone (left) and a combination of the disruptive and ecological impacts (right), compared to a scenario in which there is no change in the climate. Red and yellow indicate an increase in malaria risk, while blue indicates a reduction.
Colours in lighter shading indicate lower model confidence, while stronger colours indicate higher model confidence.
The maps show that the “disruptive” effects of climate change have a more uniform effect, driving up malaria risk across the entire continent.
However, there is greater regional variation when these effects are combined with “ecological” drivers.
The authors find that warming will increase malaria risk in regions where the temperature is currently too low for mosquitoes to survive. This includes the belt of lower latitude southern Africa, including Angola, southern Democratic Republic of Congo (DRC) and Zambia, as well as highland areas in Burundi, eastern DRC, Ethiopia, Kenya and Rwanda.
Meanwhile, they find that warming will drive down malaria transmission in the Sahel, as temperatures rise above the optimal range for mosquitoes.
Rising risk
The combined “disruptive” and “ecological” impacts of climate change will drive an additional 123m “clinical cases” of malaria across Africa, even if the current climate pledges are met, the study finds.
This will result in 532,000 additional deaths from malaria over the next 25 years, if the disease’s mortality rate remains the same, the authors warn.
The graph below shows the increase in clinical cases of malaria projected across Africa over the next 25 years, broken down into the different ecological (yellow) and disruptive (purple) drivers of malaria risk.
However, the authors stress that there are many other mechanisms through which climate change could affect malaria transmission – for example, through food insecurity, conflict, economic disruption and climate-driven migration.
“Eradicating malaria in the first half of this century would be one of the greatest accomplishments in human history,” the authors say.
They argue that accomplishing this will require “climate-resilient control strategies”, such as investing in “climate-resilient health and supply-chain infrastructure” and enhancing emergency early warning systems for storms and other extreme weather.
Dr Adugna Woyessa is a senior researcher at the Ethiopian Public Health Institute and was not involved in the study. He tells Carbon Brief that the new paper could help inform national malaria programmes across Africa.
He also suggests that the findings could be used to guide more “local studies that address evidence gaps on the estimates of climate change-attributed malaria”.
Study authors Symons and Gething tell Carbon Brief that during their study, they interviewed “many policymakers and implementers across Africa who are already grappling with what climate-resilient malaria intervention actually looks like in practice”.
These interventions include integrating malaria control into national disaster risk planning, with emergency responses after floods and cyclones, they say. They also stress the need to ensure that community health workers are “well-stocked in advance of severe weather”.
The research shows the importance of ensuring that malaria control and primary healthcare is “resilient” to the extreme weather, they say.

Climate change could lead to 500,000 ‘additional’ malaria deaths in Africa by 2050
The British government has notified the UN’s Green Climate Fund (GCF) that it will cut the contribution it pledged for 2024-2027 in half, a GCF spokesperson told Climate Home News.
The reduction, which is part of a wider UK shift from development aid to military spending, will restrict the GCF’s ability to fund projects that help developing countries cut emissions and adapt to climate change.
Harjeet Singh, director of the Satat Sampada Climate Foundation, called the UK’s decision “moral bankruptcy”, noting that Britain has a historical responsibility for climate change “as a nation built on fossil-fuelled industrialisation”.

After US retreat, countries clash over who should make up Green Climate Fund shortfall
At this week’s board meeting, Germany and Sweden encouraged wealthier developing nations to step up – an idea rejected by Saudi Arabia -
UK cuts support for climate action abroad to fund military instead
The UK’s foreign minister said the cuts to the aid budget would “deliver the biggest increase in defence spending since the Cold War”
Liane Schalatek, who observes GCF board meetings for the Heinrich Böll Foundation, said the UK’s move was “an unfortunate signal”, especially as it comes just before the GCF launches its next fundraising round.
She noted that the UK has been the biggest contributor to the GCF, and “with the UK halving – where doubling would be needed – this will give permission to others to do the same”.
There are fears that other countries could follow suit as governments in Europe trim their aid budgets, while the US has refused to deliver any further money under climate change-sceptic President Donald Trump and has also given up its seat on the GCF board.
The GCF was established in 2010, and has since funded over $15 billion of climate projects across the developing world. Its financing comes mainly from developed countries pledging money in regular replenishment rounds.
During the last GCF replenishment round in 2023, the UK’s previous Conservative government promised £1.622 billion ($2.18 billion) for the 2024-27 period, with then development minister Andrew Mitchell saying the pledge “underlines our sustained commitment to tackling climate change”.
But, as of March 2026, the UK had only handed over £655 million ($885 million) of that pledge, which is its third to the fund, and has now informed the GCF it will only deliver £815 million ($1.1 billion). The GCF’s total funding for the 2024-2027 period is $10.149 billion.
The UK’s Foreign, Commonwealth & Development Office has been contacted for comment.
Approved projects unaffected
A GCF spokesperson told Climate Home News that all current projects under implementation have guaranteed funding while the GCF is assessing what the cuts mean for the projects that are being prepared and are expected to come before the GCF board in 2026 and 2027.
“Our focus will continue to be delivering the greatest impact with the investments we make, working with the largest network of partners in the financial architecture and mobilizing the greatest amount of resources to fulfill GCF’s critical and unique mandate,” the spokesperson said.
Scientists warn El Niño could intensify climate extremes in 2026
In a separate email to GCF board members, seen by Climate Home News, the GCF’s executive director Mafalda Duarte warned that the cuts are “expected to have a material impact” on the fund’s work over the next two years.
Duarte said the cuts were part of the UK wider decision to reduce international development spending “and invest more in addressing growing security threats”.
Development to military
Announcing this decision in March, UK foreign minister Yvette Cooper said the cuts were a “hugely difficult decision” and “not ideological”, but necessary “to deliver the biggest increase in defence spending since the Cold War”. The US has been pressuring countries in the NATO alliance to boost military budgets as conflict surges around the world, from Ukraine to the Middle East.
Cooper reiterated Labour’s commitment to restore overseas development spending to 0.7% of gross national income (GNI) “when fiscal circumstances allow”, but did not provide a timeline when pressed by an opposition member of parliament. UK aid was reduced from 0.7% to 0.5% of GNI by the previous Conservative government in 2021, and is now set to fall further to 0.3%.
While the UK government has claimed it is only cutting international climate finance by around 13% compared to the previous government’s level of spending, analysis by Carbon Brief suggests that the real figure is close to 50% once inflation and accounting changes are considered.
The leadership of the UK is currently in doubt with several ministers from the ruling Labour Party calling on Prime Minister Keir Starmer to resign, with a challenge to his leadership of the party and country expected after poor local election results for Labour.

UK halves Green Climate Fund contribution, as it spends more on security
The Santa Marta summit moved beyond the blockages in the UN climate process, building a coalition of around 60 countries that want to tackle a shift away from fossil fuels. The host countries said the outcomes would feed into the voluntary roadmap on the energy transition being put together by COP30 hosts Brazil, which is due to be presented before COP31.
June’s mid-year climate talks in Bonn, followed by London Climate Action Week, will be key moments to reflect on the progress so far and work out ways to bring the strands closer together. How might that happen while fossil fuels remain the elephant in the UNFCCC room and there’s no formal place for a roadmap on the agenda?
Tune in to hear our expert reporters discussing this and other key topics set to headline at the Bonn session, both in the negotiations and on the sidelines! Questions and comments will be welcome from participants and used to inform our future coverage.

Key developments
New documents ramp up pressure on coal
‘STRICTLY CONTROL’ FOSSIL FUELS: On 22 April, China issued a set of “guiding opinions” on energy conservation and carbon reduction that urged local governments to “strictly control fossil-fuel consumption”, according to the text published by state news agency Xinhua. Hu Min, director and co-founder of the the Beijing-based Institute for Global Decarbonization Progress, said in comments to Carbon Brief that the document was a clear signal of China’s political leaders’ desire to reduce the country’s coal usage and a “way to move things forward” until more specific policies are published. Government officials noted that the opinions are of “great significance for building broader and stronger consensus across society”, reported information platform Tanpaifang.
INCREASED OVERSIGHT: The next day, the government announced new evaluation criteria for judging provinces on their efforts to meet China’s climate goals, including on raising “clean-energy consumption” and limiting “use of coal and oil”, reported Bloomberg. The 14 indicators underscore China’s “key priorities” and encourage broader carbon reduction efforts, said energy news outlet China Energy Net. They build on China’s existing inspection system to create a “much stronger accountability and compliance system”, Qin Qi, China analyst at the Centre for Research on Energy and Clean Air, told Carbon Brief. For more detail see Carbon Brief’s Q&A on what the two policies mean for China’s energy transition.
‘RARE’ SIGNAL: Both documents were issued by the highest levels of the nation’s political system, which is “extremely rare” and “reflects the strategic importance” of China’s climate goals, Wu Hongjie, deputy secretary-general of the China Carbon Neutrality 50 Forum, told Jiemian News. In a comment article for finance news outlet Caixin, Chen Lihao – a member of the Jiusan Society, environment minister Huang’s political party – said the two documents “form the institutional foundation” for China’s “full-scale transition” to a “dual control of carbon” system.
Downpours in south China
‘RECORD-BREAKING’ RAIN: Heavy rainfall is hitting central and southern China, with Hunan, Guizhou and Jiangxi provinces reporting record-breaking levels of precipitation last week, reported the Communist party-affiliated People’s Daily. It added that the government is ramping up “flood control” measures in response. On 26-27 April, one part of Guangxi province received as much as 14cm of rain per hour, reported the state-supporting newspaper Global Times. Meanwhile, Chinese vice-premier Liu Guozhong met with the World Meteorological Organization secretary-general Celeste Saulo to discuss cooperation on global “meteorological governance”, said state news agency Xinhua, with the discussion touching on early warning systems and disaster relief.
EL NIÑO RISK: Officials at China’s National Climate Center (NCC) have said that an El Niño weather pattern is “likely to set in around May” and “intensify during the summer and autumn”, said China Daily. The state-run newspaper also quoted NCC chief forecaster Chen Lijuan saying it was “premature” to conclude that the El Niño could be at its strongest in 140 years, or that it could lead to record-breaking heat, although he added that the risks of such weather are “clearly increasing”. Wang Yaqi, a senior engineer at NCC, noted that the phenomenon “could hit hydropower-dependent regions hard, pushing them to burn more fossil fuels”, according to the Hong Kong-based South China Morning Post.
Solar capacity growth slows
CLEAN CAPACITY: China’s clean-energy grid capacity now exceeds 2,400 gigawatts (GW), as of March 2026, or 60% of the total power mix, said state broadcaster CGTN in coverage of comments from energy officials at a press conference. It added that, within this, total wind and solar capacity reached 1,900GW. Energy news outlet International Energy Net cited the officials saying that China’s operational capacity for “green hydrogen” stands at 250,000 tonnes, with another 900,000 tonnes under construction.
SOLAR SLOWS: However, a data release showed that China added 41GW of new solar capacity in the first three months of 2026, reported BJX News, down from 60GW of new capacity in January-March 2025. Bloomberg noted that new solar capacity additions “slowed sharply to hit a four-year low” in March, adding that wind and thermal capacity growth also both slowed.

‘MOST AMBITIOUS GOAL’: In a separate press conference, Chinese officials confirmed to Bloomberg that a pledge in the 15th five-year plan to double “non-fossil energy” in 10 years referred to energy capacity – not generation or consumption – and would run from 2025-2035. These details were “unclear” in the five-year plan itself, the outlet added. The economic news outlet Economic Daily said that the doubling goal was “one of the most ambitious goals in China’s energy transition history”, adding that “accelerating” the energy transition would allow the country to both reduce its reliance on the international energy market and “seize the high ground in the global race” to develop low-carbon industries.
More China news
- NEW BLEND: China has begun a project to blend gas supplies with 10% hydrogen in a part of Shandong province, reported the South China Morning Post, which added that the shift could cut China’s annual carbon emissions by “roughly 30m tonnes”.
- SKY-HIGH: China launched a “high-precision” satellite to monitor greenhouse gas emissions, said Xinhua.
- SUNNY SPAIN: Chinese automaker SAIC plans to build an electric vehicle (EV) factory in Spain, reported Bloomberg.
- MING YANG: Bloomberg also said that wind turbine maker Ming Yang is considering Spain after plans for a factory in the UK were blocked.
- FORMAL COMPLAINT: China has “formally submitted a complaint” to the EU about its Industrial Accelerator Act, said China Daily.
- EU TARIFFS: China’s commerce minister said he reached a “soft landing” with EU officials on EU tariffs on imports of Chinese-made EVs, according to Reuters.
Spotlight
How war, silver and taxes propelled China’s cleantech exports
China’s export of clean-energy technologies surged in March, driven by a doubling in solar shipments, according to analysis by Carbon Brief of Chinese customs data.
The spike can be explained in part by the impact of the conflict in the Middle East, but analysts argue that a newly enacted solar export policy is also behind the figures.
In this issue, Carbon Brief explores the factors behind the export spike and whether or not it will be sustained.
China’s exports of the “new three” clean-energy technology surged by 70% year-on-year in March 2026, reaching $21.6bn, according to Carbon Brief analysis.
Exports of the three technologies – solar cells and panels, electric vehicles (EVs) and lithium-ion batteries – were also up 37% from February, the month before the Iran war.
The conflict in the Middle East is one explanation for the surge, as it has caused several countries to emphasise the need to increase non-fossil energy supplies.
However, there are also other important drivers, revealed by Carbon Brief analysis of customs data showing differences in exports between solar, EVs and batteries.
Solar exports were notably higher in March 2026 than in the previous two months, jumping 99.2% compared to February.
By contrast, neither batteries’ nor EVs’ March figures came close to the surge in solar cells.
China’s March exports of batteries rose 37% compared with the previous month, while month-on-month EV shipments increased just 1.4%.
(Figures from the China Passenger Car Association suggest a larger rise in percentage terms, but this is based on a narrower scope that does not capture all exports.)
This may be because both technologies saw strong export performance throughout the first quarter of 2026. According to the customs data, more than one million EVs were exported from China between January and March, up 73% compared with the same period last year.
These quarterly exports may have helped meet growing interest in EVs due to the conflict, with BloombergNEF estimating that sales of EVs rose to 1.1m – up 2% year-on-year – in March. (Bloomberg said, within this total, sales “cooled” in China and the US but “surged” in Europe and parts of Asia.)
Solar surge
The chart below shows the export volumes of solar cells, EVs and batteries in March 2025, plus the first three months of 2026.
March’s solar exports were capable of generating 68 gigawatts (GW), equivalent to Spain’s entire installed solar capacity, according to energy thinktank Ember.
The Ember analysis showed that 50 countries set all-time records for Chinese solar imports in March, with another 60 reaching their highest levels in six months.
Exports to Asia doubled to 39GW, while shipments to Africa surged 176% to 10GW. Combined, these two regions accounted for three-quarters of the overall increase in exports.
The Middle East conflict has boosted demand, but a domestic policy deadline was a more immediate driver, analysts told Carbon Brief.
The Chinese government removed export tax rebates for solar products on 1 April, prompting manufacturers to rush out shipments before the change took effect.
Qin Qi, China analyst at the Centre for Research on Energy and Clean Air, told Carbon Brief that such policy deadlines “can create a very sharp one-month jump in shipments”.
Batteries and EVs currently continue to receive export rebates.
Falling silver prices are another potential factor, as silver paste is used to make a key component in solar panels. The reversal of a recent price rally that had raised costs helped manufacturers make more panels ahead of the export switch, Marius Mordal Bakke, head of solar research at consultancy Rystad Energy told Reuters.
Temporary spike
Analysts predict that China’s April solar exports are unlikely to repeat March’s surge. Moreover, February exports were depressed by the Chinese New Year public holiday, making the March comparison unusually unfavourable.
“A month-on-month drop in April would not be surprising,” said Qin.
But she remains optimistic that global solar capacity additions outside China will continue to grow in 2026 due to energy supply concerns sparked by the Middle East conflict.
Dave Jones, chief analyst at Ember, said the removal of the export rebate will not “dramatically change demand”, especially as the conflict continues.
He argued that the policy could be positive, telling Carbon Brief: “This is what the global market needs: a more level playing field with China.”

Watch, read, listen
TARGET ‘DIFFICULTIES’: Two researchers at the Energy Research Institute, a state thinktank, wrote in Economic Daily that China faces several “difficulties” in meeting its new carbon-intensity targets, including already-high renewable capacity installations and high levels of energy efficiency.
COMPARE AND CONTRAST: The US-China Podcast interviewed Prof Alex Wang on China’s approach to environmentalism and his view on the country’s energy transition.
GOVERNMENT CALLOUT: State broadcaster CCTV published a segment critiquing the massive investments and special treatment that local governments gave to their EV industries, fuelling intense competition.
‘THIN ARGUMENT’: A comment in Lawfare argued that the US should focus more on the “genuine geopolitical risks of climate change and [geoengineering] development”, rather than “thin” arguments around China weaponising weather modification technologies.
