The year 2025 saw the return to power of Donald Trump, a jewellery heist at the Louvre museum in Paris and an engagement that “broke the internet”.
Amid the biggest stories of the year, climate change research continued to feature prominently in news and social media feeds.
Using data from Altmetric, which scores research papers according to the attention they receive online, Carbon Brief has compiled its annual list of the 25 most talked-about climate-related studies of the past year.
The top 10 – shown in the infographic above and list below – include research into declining butterflies, heat-related deaths, sugar intake and the massive loss of ice from the world’s glaciers:
- Indicators of Global Climate Change 2024: annual update of key indicators of the state of the climate system and human influence
- Rapid butterfly declines across the US during the 21st century
- Global warming has accelerated: Are the UN and the public well informed?
- Community estimate of global glacier mass changes from 2000 to 2023
- The EAT-Lancet Commission on healthy, sustainable and just food systems
- Carbon majors and the scientific case for climate liability
- Estimating future heat-related and cold-related mortality under climate change, demographic and adaptation scenarios in 854 European cities
- Systematic attribution of heatwaves to the emissions of carbon majors
- Ambient outdoor heat and accelerated epigenetic aging among older adults in the US
- Rising temperatures increase added sugar intake disproportionately in disadvantaged groups in the US
Later in this article, Carbon Brief looks at the rest of the top 25 and provides analysis of the most featured journals, as well as the gender diversity and country of origin of authors.
New for this year is the inclusion of Altmetric’s new “sentiment analysis”, which scores how positive or negative a paper’s social media attention has been.
(For Carbon Brief’s previous Altmetric articles, see the links for 2024, 2023, 2022, 2021, 2020, 2019, 2018, 2017, 2016 and 2015.)
Global indicators
The top-scoring climate paper of 2025, ranking 24th of any research paper on any topic, is the annual update of the “Indicators of Global Climate Change” (IGCC) report.
The report was established in 2023 to help fill the gap in climate information between assessments of the Intergovernmental Panel on Climate Change (IPCC), which can take up to seven years to complete. It includes the latest data on global temperatures, the remaining carbon budget, greenhouse gas emissions and – for the first time – sea level rise.

The paper, published in Earth System Science Data, has an Altmetric score of 4,099. This makes it the lowest top-scoring climate paper in Carbon Brief’s list since 2017.
(An Altmetric score combines the mentions that published peer-reviewed research has received from online news articles, blogs, Wikipedia and on social media platforms such as Facebook, Reddit, Twitter and Bluesky. See an earlier Carbon Brief article for more on how Altmetric’s scoring system works.)
Previous editions of the IGCC have also appeared in Carbon Brief’s list – the 2024 and 2023 iterations ranked 17th and 18th, respectively.
This year’s paper was mentioned 556 times in online news stories, including in the Associated Press, Guardian, Independent, Hill and BBC News.
Many outlets led their coverage with the study’s findings on the global “carbon budget”. This warned that the remaining carbon budget to limit warming to 1.5C will be exhausted in just three years if global emissions continue at their current rate.

In a Carbon Brief guest post about the study, authors Prof Piers Forster and Dr Debbie Rosen from the University of Leeds wrote:
“It is also now inevitable that global temperatures will reach 1.5C of long-term warming in the next few years unless society takes drastic, transformative action…Every year of delay brings reaching 1.5C – or even higher temperatures – closer.”
Forster, who was awarded a CBE in the 2026 new year honours list, tells Carbon Brief that media coverage of the study was “great” at “putting recent extreme weather in the context of rapid long-term rates of global warming”.
However, he adds:
“Climate stories are not getting the coverage they deserve or need at the moment so the community needs to get all the help we can for getting clear consistent messages out there.”
The paper was tweeted more than 300 times and posted on Bluesky more than 950 times. It also appeared in 22 blogs.
Using AI, Altmetric now analyses the “sentiment” of this social media attention. As the summary figure below shows, the posts about this paper were largely positive, with an approximate 3:1 split of positive and negative attention.

Butterfly decline
With an Altmetric score of 3,828, the second-highest scoring climate paper warns of “widespread” declines in butterfly numbers across the US since the turn of the century.
The paper, titled “Rapid butterfly declines across the US during the 21st century” and published in Science, identifies a 22% fall in butterfly numbers across more than 500 species between 2000 and 2020.
(There is a higher-scoring paper, “The 2025 state of the climate report: a planet on the brink”, in the journal BioScience, but it is a “special report” and was not formally peer reviewed.)

The scale of the decline suggests “multiple and broadly acting threats, including habitat loss, climate change and pesticide use”, the paper says. The authors find that “species generally had stronger declines in more southerly parts of their ranges”, with some of the most negative trends in the driest and “most rapidly warming” US states.
The research was covered in 560 news articles, including the New York Times, Guardian, Associated Press, NPR, El País and BBC News. Much of the news coverage led with the 22% decline figure.
The paper was also mentioned in 13 blogs, more than 750 Bluesky posts and more than 600 tweets.
The sentiment analysis reveals that social media posts about the paper were largely negative. However, closer inspection reveals that this negativity is predominantly towards the findings of the paper, not the research itself.
For example, a Bluesky post on the “distressing” findings by one of the study’s authors is designated as “neutral negative” by Altmetric’s AI analysis.
In a response to a query from Carbon Brief, Altmetric explains that the “goal is to measure how people feel about the research paper itself, not the topic it discusses”. However, in some cases the line can be “blurred” as the AI “sometimes struggles to separate the subject matter from the critique”. The organisation adds that it is “continuously working on improving our models to better distinguish between the post’s content and the research output”.

On the attention that the paper received, lead author Dr Collin Edwards of Washington State University in Vancouver says that “first and foremost, people care about butterflies and our results are broad-reaching, unequivocal and, unfortunately, very concerning”.
Edwards tells Carbon Brief he hopes the clarity of the writing made the paper accessible to readers, noting that he and his co-authors “sweat[ed] over every word”.
The resulting news coverage “accurately captured the science”, Edwards says:
“Much as I wish our results were less consistently grim, the consistency and simplicity of our findings mean that even if a news story only provides the highest level summary, it isn’t misleading readers by skipping some key caveat or nuance that changes the interpretation.”
Warming ‘acceleration’
In third place in Carbon Brief’s list for 2025 is the latest scientific paper from veteran climatologist Dr James Hansen, former director of the NASA Goddard Institute for Space Studies and now adjunct professor at Columbia University’s Earth Institute.
The paper, titled “Global warming has accelerated: Are the UN and the public well-informed?” was published in the journal Environment: Science and Policy for Sustainable Development. It generated an Altmetric score of 3,474.

The study estimates that the record-high global temperatures in the last few years were caused by a combination of El Niño and a reduction in air pollution from international shipping.
The findings suggest that the cooling effect of aerosols – tiny, light‑scattering particles produced mainly by burning fossil fuels – has masked more of the warming driven by greenhouse gases than previously estimated by the IPCC.
As efforts to tackle air pollution continue to reduce aerosol emissions, warming will accelerate further – reaching 2C by 2045, according to the research.
The paper was covered by almost 400 news stories – driven, in part, by Hansen’s comments in a press briefing that the Paris Agreement’s 2C warming limit was already “dead”.
Hansen’s analysis received a sceptical response from some scientists. For example, Dr Valerie Masson-Delmotte, an IPCC co-chair for its most recent assessment report on climate science, told Agence France-Presse the research “is not published in a climate science journal and it formulates a certain number of hypotheses that are not consistent with all the available observations”.
In addition, other estimates, including by Carbon Brief, suggest new shipping regulations have made a smaller contribution to warming than estimated by Hansen.
Hansen tells Carbon Brief that the paper “did ok” in terms of media coverage, although notes “it’s on [scientists] to do a better job of making clear what the core issues are in the physics of climate change”.
With more than 1,000 tweets, the paper scored highest in the top 25 for posts on Twitter. It was also mentioned in more than 800 Bluesky posts and on 27 blogs.
The sentiment analysis suggests that these posts were largely positive, with just a small percentage of negative comments.

Making the top 10
Ranking fourth in Carbon Brief’s analysis is a Nature paper calculating changes in global glacier mass over 2000-23. The study finds glaciers worldwide lost 273bn tonnes of ice annually over that time – with losses increasing by 36% between 2000-11 and 2012-23.
The study has an Altmetric score of 3,199. It received more news coverage than any other paper in this year’s top 25, amassing 1,187 mentions. with outlets including the Guardian, Associated Press and Economic Times.
At number five, with an Altmetric score of 2,860, is the EAT-Lancet Commission on healthy, sustainable and just food systems.
Carbon Brief’s coverage of the report highlights that “a global shift towards ‘healthier’ diets could cut non-CO2 greenhouse gas emissions, such as methane, from agriculture by 15% by 2050”. It adds:
“The findings build on the widely cited 2019 report from the EAT-Lancet Commission – a group of leading experts in nutrition, climate, economics, health, social sciences and agriculture from around the world.”
Also making the top 10 – ranking sixth and eighth – are a pair of papers published in Nature, which both link extreme heat to the emissions of specific “carbon majors” – large producers of fossil fuels, such as ExxonMobil, Shell and Saudi Aramco,.
The first is a perspective, titled “Carbon majors and the scientific case for climate liability”, published in April. It begins:
“Will it ever be possible to sue anyone for damaging the climate? Twenty years after this question was first posed, we argue that the scientific case for climate liability is closed. Here we detail the scientific and legal implications of an ‘end-to-end’ attribution that links fossil fuel producers to specific damages from warming.”
The authors find “trillions (of US$) in economic losses attributable to the extreme heat caused by emissions from individual companies”.
The paper was mentioned 1,329 times on Bluesky – the highest in this year’s top 25. It was also mentioned in around 270 news stories.
Published four months later, the second paper uses extreme event attribution to assess the impact of climate change on more than 200 heatwaves recorded since the year 2000.
The authors find one-quarter of the heatwaves would have been “virtually impossible” without human-caused global warming. They add that the heatwaves were, on average, 1.7C hotter due to climate change, with half of this increase due to emissions stemming from the operations and production of carbon majors.
This study was mentioned in almost 300 news stories – including by Carbon Brief – as well as 222 tweets and 823 posts on Bluesky.
In seventh place is a Nature Medicine study, which quantifies how heat-related and cold-related deaths will change over the coming century as the climate warms.
A related research briefing explains the main findings of the paper:
“Heat-related deaths are estimated to increase more rapidly than cold-related deaths are estimated to decrease under future climate change scenarios across European cities. An unrealistic degree of adaptation to heat would be required to revert this trend, indicating the need for strong policies to reduce greenhouse gases emissions.”
The paper was mentioned 345 times in the news, including in the Financial Times, New Scientist, Guardian and Bloomberg.
The paper in ninth place also analyses the health impacts of extreme heat. The study, published in Science Advances, finds that extreme heat can speed up biological ageing in older people.
Rounding out the top 10 is a Nature Climate Change study, titled “Rising temperatures increase added sugar intake disproportionately in disadvantaged groups in the US”.
The study finds that at higher temperatures, people in the US consume more sugar – mainly due to “higher consumption of sugar-sweetened beverages and frozen desserts”. The authors project that warming of 5C would drive additional sugar consumption of around 3 grams per day, “with vulnerable groups at an even higher risk”.
Elsewhere in the top 25
The rest of the top 25 includes a wide range of research, from “glacier extinction” and wildfires to Amazon drought and penguin guano.
In 13th place is a Nature Climate Change study that finds the wealthiest 10% of people – defined as those who earn at least €42,980 (£36,605) per year – contributed seven times more to the rise in monthly heat extremes around the world than the global average.
The authors also explore country-level emissions, finding that the wealthiest 10% in the US produced the emissions that caused a doubling in heat extremes across “vulnerable regions” globally.
(See Carbon Brief’s coverage of the paper for more details.)
In 15th place is the annual Lancet Countdown on health and climate change – a lengthy report with more than 120 authors.
The study warns that “climate change is increasingly destabilising the planetary systems and environmental conditions on which human life depends”.
This annual analysis from the Lancet often features in Carbon Brief’s top 25 analysis. After three years in the Carbon Brief’s top 10 over 2020-23, the report landed in 20th place in 2023 and missed out on a spot in the top 25 altogether in 2024.
In 16th place is a Science Advances study, titled “Increasing rat numbers in cities are linked to climate warming, urbanisation and human population”. The study uses public complaint and inspection data from 16 cities around the world to estimate changes in rat populations.
It finds that “warming temperatures and more people living in cities may be expanding the seasonal activity periods and food availability for urban rats”.
The study received 320 new mentions, including in the Washington Post, New Scientist and National Geographic.
In 21st place is a Nature Climate Change paper, titled “Peak glacier extinction in the mid-21st century”. The study authors “project a sharp rise in the number of glaciers disappearing worldwide, peaking between 2041 and 2055 with up to ~4,000 glaciers vanishing annually”.
Completing the top 25 is a Nature study on the “prudent planetary limit for geological carbon storage” – where captured CO2 is injected deep underground, where it can stay trapped for thousands of years.
In a Carbon Brief guest post, study authors Dr Matthew Gidden and Prof Joeri Rogelj explain that carbon dioxide removal will only be effective at limiting global temperature rise if captured CO2 is injected “deep underground, where it can stay trapped for thousands of years”.
The guest post warns that “geological carbon storage is not limitless”. It states that “if all available safe carbon storage capacity were used for CO2 removal, this would contribute to only a 0.7C reduction in global warming”.
Top journals
The journal Nature dominates Carbon Brief’s top 25, with seven papers featured.
Many other journals in the Springer Nature stable also feature, including Nature Climate Change (three), Communications Earth & Environment (two), as well as Nature Ecology & Evolution, Nature Medicine and Nature Reviews Earth & Environment (one each).
Also appearing more than once in the top 25 are Science Advances (three), Science (two) and the Lancet (two).
This is shown in the graphic below.

All the final scores for 2025 can be found in this spreadsheet.
Diversity in the top 25
The top 25 climate papers of 2025 cover a huge range of topics and scope. However, analysis of their authors reveals a distinct lack of diversity.
In total, the top 25 includes more than 650 authors – the highest number since Carbon Brief began this analysis in 2022.
This is largely due to a few publications with an exceptionally high number of authors. For example, the 2025 report of the Lancet Countdown on health and climate change has almost 130 authors alone, accounting for almost one-fifth of authors in this analysis.
Carbon Brief recorded the gender and country of affiliation for each of these authors. (The methodology used was developed by Carbon Brief for analysis presented in a special 2021 series on climate justice.)
The analysis reveals that 88% of the authors of the climate papers most featured in the media in 2025 are from institutions in the global north.
Carbon Brief defines the global north as North America, Europe, Japan, Australia and New Zealand. It defines the global south as Asia (excluding Japan), Africa, Oceania (excluding Australia and New Zealand), Latin America and the Caribbean.
The analysis shows that 53% of authors are from European institutions, while only 1% of authors are from institutions in Africa.
Further data analysis shows that there are also inequalities within continents. The map below shows the percentage of authors from each country, where dark blue indicates a higher percentage. Countries that are not represented by any authors in the analysis are shown in grey.

The top-ranking countries on this map are the US and the UK, which account for 26% and 16% of the authors, respectively.
Carbon Brief also analysed the gender of the authors.
Only one-third of authors from the top 25 climate papers of 2025 are women and only five of the 25 papers list a woman as lead author.
The plot below shows the number of authors from each continent, separated into men (dark blue) and women (light blue).

The full spreadsheet showing the results of this data analysis can be found here. For more on the biases in climate publishing, see Carbon Brief’s article on the lack of diversity in climate-science research.

Fossil fuel expansion threatens COP31 hosts’ credibility, experts warn
Türkiye and Australia risk losing their credibility as hosts of this year’s COP31 UN climate summit if they keep betting on fossil fuels at home, climate policy experts have warned.
As governments are expected to continue fraught talks over how to advance the global transition away from oil, coal and gas in Antalya this November, both of the co-host countries are pursuing fossil fuel expansion at home, without a national timeline to phase out their use.
Türkiye has accelerated its rollout of wind and solar energy in recent years. But that progress has yet to make a dent in the country’s dependence on fossil fuels for power, as demand growth has outpaced the renewables build-out, new analysis by Climate Action Tracker (CAT) has found.
The share of electricity generated by burning coal and fossil gas – 56% in 2025 – has barely changed since 2019, and total fossil fuel use in the power sector, and the emissions it produces, are still rising, according to the report released on Friday.
The Turkish government has also signalled that fossil fuels will remain a central component of its energy mix and has outlined plans to expand the country’s burgeoning domestic gas production in the Black Sea.
‘Need to demonstrate seriousness’
Australia, which will chair the Antalya negotiations, relies on fossil fuels for over 60% of its electricity, with coal alone still supplying 45%. According to experts, it lacks an ambitious plan to shift away from fossil fuels at home, relying heavily on carbon offsetting to reach its climate targets.
Australia is also the world’s third-largest fossil fuel exporter and has plans to expand its coal and gas production, which is backed by significant government subsidies. It recently upset climate groups by approving an extension of the Saraji open-cut coal mine in Queensland.
Türkiye says it has “final decision” at COP31 despite Australia running negotiations
Jennifer Morgan, a senior fellow with the Fletcher School of Law and Diplomacy at Tufts University and former climate envoy for Germany, said Türkiye and Australia need to demonstrate their seriousness about their COP presidency roles by leading by example on the energy transition.
“They have made progress in renewable energy,” she told reporters this week. “But I think their credibility – and their ability to therefore bring momentum and good outcomes to the COP – will depend on their taking further action at home.”
Türkiye’s electrification homework
The co-hosts’ fossil fuel policies are being scrutinised in the run-up to the annual UN climate summit, with much riding on the signal climate diplomacy sends on the energy transition.
Türkiye has so far stopped short of putting any overt political capital behind the fossil fuel transition itself. It has instead been rallying support for a new global electrification target of 35% by 2035, seen as the centrepiece of this year’s non-negotiated Action Agenda put forward by Ankara.
COP31 president Murat Kurum said last week the push to electrify economies – through measures like electric vehicles and heat pumps – will “automatically” lead to a reduction in the use of fossil fuels.
Türkiye’s own energy plan projects the country’s electrification rate would fall short on the global target and only hit 25% by 2035, according to the CAT report, which called for a “substantial step-change” in electrification policies and the deployment of more renewable power and grid infrastructure.
Coal still dominant
CAT’s analysts also warned that, without a parallel phase-out of fossil fuels, rising electricity demand risks being met in part by coal and gas, failing to deliver the emissions reductions the electrification target is meant to achieve.
Türkiye has had some success in its clean energy build-out: the share of electricity generation from wind and solar rose to 22% in 2025, up from 12% in 2020, according to the CAT report.
But coal’s role in Türkiye’s electricity mix has also grown, in both its share and absolute terms, over the past decade. And while reliance on fossil gas has declined overall, it still plays an important role in Ankara’s energy policy, which is pushing to boost domestic gas production in the Black Sea.
Dr Niklas Höhne from the NewClimate Institute said the government could demonstrate leadership as COP31 president by building on its recent successes in increasing its renewable energy capacity and announcing targets and plans to phase out coal and gas ahead of the summit.
According to CAT, Türkiye should phase out coal by 2040 and fossil gas by 2045 at the latest to align its power sector with global efforts to limit the rise in global temperatures to 1.5C above preindustrial times.
Türkiye quiet on fossil fuel roadmap
Ümit Şahin, coordinator of climate change studies at the Istanbul Policy Center (IPM), said Türkiye’s strategy is to approach the fossil fuel debate exclusively from the “end-use point of view”.
“I don’t expect any push from the Turkish presidency to the producer countries in terms of fossil fuel production,” he told reporters.
Neither does Şahin believe the Turkish presidency will throw its political weight behind another big-ticket item for COP31: a new global roadmap to transition away from fossil fuels.
Brazil took on the responsibility to voluntarily draft this document outside of the formal negotiations as a way to break the deadlock at last year’s UN summit in Belém when governments clashed over whether to develop one.
The outgoing COP30 presidency will deliver the roadmap in early November – but it will be up to Türkiye and Australia to guide countries towards a decision on how the blueprint will be taken forward, either inside or outside the negotiations.
Leadership needed
Australia’s Chris Bowen, COP31’s president of negotiations, promised to lobby producing countries to deliver a “meaningful step forward” on the fossil fuel transition in an interview with The Guardian earlier this year. But he has been quiet on the role Australia sees for the fossil fuel transition roadmap.
Natalie Jones, senior policy advisor at the International Institute for Sustainable Development (IISD), said the COP31 co-presidents “must provide clear leadership” on this process.
“This roadmap cannot be left in a dusty drawer,” she told journalists. “Rather, it must be translated into action, with all countries identifying what elements they can adopt or develop in their own national roadmap.”
Like Türkiye, Australia has yet to produce a national blueprint for winding down coal, gas and oil. Rather than moving toward a phase-out, state and federal governments have kept expanding fossil fuel licensing over the past year, according to a new analysis published this month by Climate Analytics.
Under existing policy, both coal and gas are on track to remain in Australia’s power system as late as 2050 – a trajectory the report defines as incompatible with the 1.5C limit the country says it’s committed to.
No binding end dates for the Netherlands
Analysts are watching out for national transition roadmaps as a bellwether for governments that claim to be leaders in the global shift away from fossil fuels.


The Netherlands, which co-hosted the first fossil fuel transition conference in Santa Marta this year, published its own domestic roadmap earlier this week. The document followed through on a pledge that “leadership on transitioning away from fossil fuels must be backed by concrete action, not just ambitious words”, said a spokesperson for Stientje van Veldhoven, the Dutch minister for climate policy.
But experts criticised the plan for failing to set a binding end date for the country’s fossil fuel production and use. While targeting a rapid increase in renewables capacity, the Dutch government only commits to phasing out oil, gas and coal “in the energy and feedstock system to eventually zero, and to minimise fossil use” by 2050.
Yvo de Boer, a former Dutch diplomat and executive secretary of the UN climate body, said the Dutch roadmap falls short of what’s needed to give industry the confidence to deploy capital in support of the energy transition with greater predictability.
“Ultimately, a roadmap without deadlines is nothing more than a footpath paved with good intentions,” he added, writing on LinkedIn.

How clean energy can boost business for Africa’s food producers
Despite millions of dollars in grants and technical help for African businesses to power farming and other food production activities with renewable energy, most efforts remain stuck at the early stages because they struggle to find the investors, markets and expertise they need to grow.
This was the message from a coalition of global institutions working on energy, water and agriculture at this month’s Africa Food Systems Forum in Kigali, Rwanda.
“Energy, agriculture, water and nutrition actors rarely design solutions together,” the Agri-Energy Coalition said in a Call to Action on powering food systems with clean energy.
Using more renewables – especially solar power – to drive food systems would reduce food losses, ensure year-round availability and affordability of healthy foods, and improve productivity, income and resilience among farmers, food processors and other small enterprises, the coalition added.
In an interview with Climate Home News at the forum, Olamide Niyi-Afuye, CEO of the Africa Minigrid Developers Association (AMDA) – a body representing private-sector developers of small-scale, off-grid electricity systems across the continent – said its members are starting to recognise this interdependence and are increasingly considering businesses that combine energy with agricultural activities.
This, Niyi-Afuye added, could lead to greater supply and use of clean power for key processes like irrigation, food processing and storage, creating new sources of revenue for both sectors.
CHN: Conversations at the Africa Food Systems Forum highlighted how organisations working in energy and agriculture often operate in silos. What has hampered their collaboration, and how has that affected Africa’s economic development?
A: Most mini-grid companies in Africa were primarily incentivised to achieve connections. If you look at some ongoing projects, you see a cost-per-connection model [of revenue]. When a subsidy is tied to achieving a connection, regardless of whether it is a productive connection, you might not notice the problem until five years down the line, when you realise the cash flows are not what you projected.
Despite African walkout, fractious land COP ends without drought deal
So now we’re in a “come-to-Jesus moment” as an industry, where we’re righting the wrongs and adjusting our business models to make sure companies do not go bust and there is some level of sustainability over the long term.
The saying is not wrong that we’ve been working in our own silos because we’ve focused on the smaller things instead of the helicopter view. There needs to be cross-pollination [between the energy and agriculture sectors] because, if we are thinking about industrialisation, energy is a key driver of industrialisation. We will not achieve that if we’re not in the room and part of those conversations.
CHN: Productive use of energy is intended to ensure electricity access goes beyond lighting homes to improving livelihoods, creating jobs and powering equipment. But what happens when farmers cannot afford the equipment they need to do that? How can energy, agriculture and equipment players work together to make the transition more accessible?
A: That’s why we’re having conversations with companies set up to de-risk the agriculture sector. By leveraging that connection, we’re able to aggregate potential energy needs and develop instruments that make equipment more affordable through bulk procurement.
We can have arrangements that make it easier for farmers and food producers to lease equipment and eventually own it over a period. There’s no real pressure to recover the capital very quickly because you’re looking at scale.


There is a whole lot across the agricultural value chain that needs energy, from farming and harvesting to food processing and value-addition. We need to understand the energy needs across the value chain and bring our members in to provide solutions.
Developers do not necessarily need to provide every productive-use solution themselves. They can partner with equipment suppliers, financiers, agribusinesses and other service providers to enable customers to use electricity productively. The objective is simple: do not just electrify communities; enable economic activity that uses that electricity.
CHN: When Africa’s industrialisation is discussed, you hear things like renewables cannot provide enough baseload, while some food processors are sceptical about switching to renewable energy because of these concerns about reliability. What is your response?
A: It’s not a controversial statement to say that a typical baseload is usually from the grid, and it’s usually from multiple sources including renewable energy. For large-scale operations, we can look at blending multiple sources of energy. But how do we solve the problem of a mid-sized farmer? We can solve it with a mini-grid using renewable energy.
Comment: Every country needs a model to help optimise its energy transition
If you go to a small farmer in a rural area, they don’t care about what source of energy they’re getting. They just want something that can help them get from A to B. If you look at the direct energy needs of farmers and food processors, I’m sure 90 percent of their consumption can be solved by renewable energy. Let’s start with that problem first. Then, as they scale, they might need to ramp up, and we can start talking about a bigger baseload.
CHN: How much agricultural value is lost because farmers and food businesses lack reliable, affordable electricity?
A: If you look at, for example, the fact that we need to maybe plant tomatoes or strawberries in Jos before it gets to Lagos [Nigeria], which most likely is by road, I can assure you that a good chunk, if not stored properly, would be bad by then. So the fact that we do not have energy is in itself a lost opportunity to maximise the potential of the agriculture sector. So until we’ve solved the energy problem, we will not salvage waste – and for me that is a lost opportunity.
CHN: AGRA, an institution focused on scaling agricultural innovations to help smallholder farmers, estimates a massive shortfall between current investments in the continent’s food systems and what is actually needed to build a resilient, profitable agricultural economy – to the tune of $180 billion per year. Can integrating energy into food systems help bridge that gap?
A: Yes – if energy can help unlock the potential to earn more money, investors will follow the money. Investments go where there is certainty, and until there is certainty around cash flow and revenue, investment will be limited.
My vision is to see more Power Purchase Agreements (PPAs) being signed between energy players and the agriculture sector. We can start by getting people into the room, understanding their pain points, crafting a framework and documentation that works for both parties, and then seeing deals happen.

Human security relies on adapting to the world’s new climate reality
Cristina Rumbaitis del Rio is a senior advisor on adaptation and resilience with the United Nations Foundation and Mattias Söderberg is global climate lead at Danish NGO DanChurchAid.
Recent extreme events – from wildfires and heatwaves in Europe to flash flooding following a glacier collapse in Nepal – have shocked and devastated communities, bringing years of warnings about such climate impacts to the doorstep of communities around the world.
One thing is certain: the new climate reality is here – and the adaptation strategies designed for yesterday’s world are no longer sufficient.
Attribution science has since shown that the hotter and more frequent heatwaves we’re experiencing around the world would have been virtually impossible without today’s high concentrations of greenhouse gases in the atmosphere. Climate shocks are now so severe that they reverberate through supply chains, food and water systems, financial markets and the movement of people.
They must be a catalyst for a new way of thinking about adaptation and resilience, and how we finance solutions that work. A failure to invest in adaptation in one region can create costs far beyond it, which is why the concept of shared resilience is critical for leaders to grasp.
Investment not charity
At the UN General Assembly (UNGA 81) this month, leaders have an opportunity to translate today’s urgency into concrete commitments on adaptation and loss and damage finance ahead of COP31.
Those commitments are needed to underpin global stability, shared prosperity and human security. Governments should use this moment to show what a new response looks like: finance that reaches communities faster, supports locally grounded solutions, strengthens national systems, and helps countries prepare before the next shock arrives.
If we want sustained economic growth, food and water security, and resilient and prosperous societies across every region, adaptation must be at the heart of today’s development and security agenda. It cannot be just a future planning consideration or a narrow issue for climate ministries. Adaptation is now everyone’s business – and it must be financed fast and fair.
UN Secretary-General António Guterres has repeatedly framed climate finance as an investment rather than charity, warning that “a world in climate chaos cannot be a world at peace” and describing human security as freedom from the chronic and sudden disruptions that climate change multiplies.
What’s more, adaptation delivers a real return-on-investment, with researchers estimating that every dollar invested produces $10 in benefits, saving lives, protecting livelihoods, and reducing the costs of future disasters.
Hitting adaptation limits
The urgency to scale adaptation systematically is growing. The newly released “Limiting Overshoot” report from the UN Environment Programme (UNEP) confirms what scientists have long warned: exceeding global warming of 1.5C is now unavoidable under current policies. Yet, how high temperatures rise – and how long the world remains above the 1.5C threshold – will determine whether communities, economies and entire ecosystems can keep pace.
There are limits to adaptation. When we breach those limits, lives and livelihoods are lost, and people and ecosystems suffer greatly. We cannot simply build yesterday’s infrastructure a little stronger and assume it will be enough.

We need to fundamentally change the systems that determine how societies anticipate, absorb and recover from both immediate and evolving non-linear climate shocks. This includes transforming physical systems, such as infrastructure, and the governance systems that affect where and how we live to how we maintain our health and wellbeing.
Finance today is nowhere near the scale of the challenge.
The UNEP “Adaptation Gap Report 2025” estimates the shortfall in adaptation finance in developing countries at $284 billion–$339 billion a year – roughly 12 to 14 times current international public flows of around $26 billion. That gap is a development, economic and human security problem, especially for the most vulnerable populations who have contributed the least to causing the climate crisis.
Building resilience into financial systems
There are already signs of what a more systemic adaptation response could look like. Communities around the world are delivering practical solutions at local level, even as adaptation finance remains notoriously, and appallingly, difficult to access. Cyclone-resistant homes, local forecasting capacities, drought-resistant crops, heat insurance for pregnant informal workers and mangrove restoration are rooted in local knowledge and lived experience, while delivering benefits far beyond the communities where they originate from.
But local innovation alone is not enough; the systems around it need to be resilient too.
Jamaica offers one example. The country has built a multi-layered disaster-risk financing framework, including a catastrophe bond and contingency funds, through sustained fiscal discipline and proactive investment. Its debt-to-GDP ratio fell from around 147% in 2012 to around 62% in 202-25. That groundwork matters when disaster strikes.
Hurricane Melissa’s destruction shows need for climate resilience push
Following Hurricane Melissa, Jamaica was able to secure billions of dollars in reconstruction financing from multilateral banks – finance that might otherwise have been much harder to access. The lesson is clear: resilience can be built into the financial architecture of a country before a crisis arrives. That is the shift we now need to make at scale.
The foundations already exist – in Kingston’s fiscal reforms, in early-warning systems from the Sahel to the Pacific, and in every community that adapted before disaster struck. What is still missing is the political will, and the finance, to take what works and put it to work everywhere, at the speed our world’s new climate reality demands.
