Scientists have challenged the conclusions of a new study suggesting that the planet has already exceeded the 1.5C warming threshold set under the Paris Agreement.
Climate change is typically measured as the average global temperature increase relative to a “pre-industrial baseline”. The UN Intergovernmental Panel on Climate Change (IPCC), for example, uses the average temperature over 1850-1900 as their historical baseline. The planet has already warmed by around 1.2C compared to this period.
The new study, published in Nature Climate Change, uses proxy data from sea sponges in the Caribbean Sea to create a record of ocean temperatures from 1700 to the present day. This data suggests that warming started 40 years before the IPCC’s pre-industrial baseline period began.
Based on this new record, the authors say “warming is 0.5C higher than IPCC estimates”.
This means that “the global warming clock for emission reductions to minimise the risk of dangerous climate change has been brought forward by at least a decade”, the lead author told a press briefing.
However, many experts have warned that the framing of the study is misleading, arguing that the finding has no bearing on the Paris Agreement 1.5C limit, because it specifically “describes temperature rise relative to the late 19th century”.
Prof Richard Betts, head of climate impacts research at the UK Met Office Hadley Centre, who was not involved in the study, tells Carbon Brief that, crucially, the study “does not mean that impacts of climate change will occur earlier than expected”.
Other experts raised doubts that the 0.5C warming in the 1800s is human-caused, while many cautioned that proxy data from a single location should not be used to make assumptions about the entire planet.
The University of Oxford’s Prof Yadvinder Malhi, who was also not involved in the study, cautions that “the way these findings have been communicated is flawed, and has the potential to add unnecessary confusion to public debate on climate change”.
Shifting baselines
Humans have been releasing greenhouse gases into the atmosphere for centuries, causing global temperatures to rise.
In IPCC reports – considered the most authoritative summaries on climate science – scientists use a combination of land surface air temperatures and sea surface temperatures to assess changes in global mean surface temperatures (GMST).
The UN body reports global warming against a “pre-industrial baseline” of 1850-1900. It describes this baseline as “a pragmatic choice based upon data availability considerations” – in part because much of the observed climate data they use is only available from 1850.
For example, the Met Office’s HadSST4 dataset – one of the three datasets used in IPCC estimates of sea surface temperatures – goes back as far as 1850.
The IPCC also recognises that “both anthropogenic and natural changes to the climate occurred” before the 1850-1900 baseline. For example, in its 2021 report on climate science, the IPCC estimates that between 1750 and 1850-1900, GMST increased by around 0.1C. Of this, human activity was responsible for 0.0-0.2C, it says.
Nonetheless, researchers have typically followed suit in using the 1850-1900 average as their “pre-industrial baseline” to measure global warming.
In 2015, countries agreed under the Paris Agreement to hold the increase in the global average temperature to well below 2C above pre-industrial levels and pursue efforts to limit warming to 1.5C. “Pre-industrial” was not clearly defined in the agreement, but it has generally been taken to mean the average temperature over 1850-1900.
However, some scientists argue that the “pre-industrial baseline” period should begin before 1850.
The new study uses proxy data taken from sea sponges from the Caribbean sea, to present a timeseries of regional ocean temperatures from 1700 to the present day. Scientists collected sclerosponges from the ocean mixed layer – a region of ocean where heat is exchanged between the atmosphere and the ocean interior.
Between 1700-90 and 1840-60, the proxy data shows ocean warming of around 0.9C, according to the study. In the intervening time, there was some cooling, largely caused by volcanic eruptions, the authors say.
The plot below shows the proxy data (blue) from the year 1770, alongside the HadSST4 observed temperature record (purple), which begins in 1850, relative to a 1961-90 reference period. The authors have applied a 0.9C “offset” to their proxy data to account for pre-industrial temperature increase.
By comparing their proxy data against existing records of global temperature changes, the authors find “strong empirical evidence that the Caribbean ocean mixed layer has warmed proportionately to the average global increase in sea surface temperature, over the last ~50 years”.
The authors assume that the 0.9C offset “can be applied to land-air as well as the ocean mixed layer anomalies”, therefore concluding that GMST increased by 0.9C between 1700-1860 and 1961-90.
Meanwhile, global ocean temperatures measured using HadSST4 show only 0.4C of warming relative to the IPCC’s 1850-1900 pre-industrial period.
As such, the authors suggest that human-caused warming to date is actually 0.5C higher than IPCC estimates.
Dr Malcolm McCulloch – an emeritus professor at the University of Western Australia and lead author on the study – told a press briefing that, according to his study, the 1.5C Paris temperature threshold has already been crossed in around 2010-12.
He continued:
“It means that now, temperatures are at least 1.7C above the pre-industrial level. It also means that the 2C target will be passed in late 2020 unless there are major reductions in emissions…
“The big picture is that the global warming clock for emission reductions to minimise the risk of dangerous climate change has been brought forward by at least a decade”.
However, many scientists are concerned about this framing of the study.
Warming limits
Dr Friederike Otto, who was not involved in the study, is a senior lecturer in climate science at Imperial College London’s Grantham Institute. She says the paper “does not tell us anything about whether we have exceeded the 1.5C temperature limit set in the Paris Agreement”.
She continues:
“That limit was established as the threshold of unacceptably dangerous warming and describes temperature rise relative to the late 19th century. If this study has indeed identified warming from before the mid-1800s, that doesn’t mean the planet is any closer to breaking the 1.5C limit as it is widely understood.”
(The IPCC best estimate – in all but the highest emission scenario – is that global warming will pass 1.5C in the first half of the 2030s.)
Mahli adds:
“Our models of climate warming impacts are based on warming relative to 1850-1900 and moving the baseline definition of pre-industrial does not make these expected impacts worse…
“It is the date of the reference period that matters rather than whether it is labelled pre-industrial or not. The period 1850-1900 is a period of relatively reliable global data when industrial era human-caused climate change was likely negligible.”
Dr Andrew King is a senior lecturer in climate science at the University of Melbourne and was not involved in the study. He tells Carbon Brief that the findings of the study do not have any implications for the Paris Agreement warming limits, because these were “written in 2015 with a view to limiting further global warming from that point onwards”.
He adds:
“While the lack of clarity on what pre-industrial means was problematic, it doesn’t really affect that goal or any of the analyses on climate impacts at global warming levels that have been performed.”
King also tells Carbon Brief that the authors have not demonstrated that pre-1850s warming is due to human activity.
Malhi agrees that “this early industrial-era warming, if real, is almost certainly not human-caused”. He notes that human-caused emissions over 1750-1900 account for only 2.5% of total emissions to date, and says they are “unlikely to have caused substantial warming compared to the 1.4C of warming caused by the remaining 97.5% of cumulative emissions”.
Dr Duo Chan, a lecturer in climate sciences at the University of Southampton, also advises “caution” when interpreting the results, noting that “this new warming estimate does not align” with historical estimates of the different factors that affect the climate.
He notes that, according to Berkeley Earth temperature estimates, the land warmed by around 0.05C per decade over 1850-1900. The new proxy data from the sponges suggests that the ocean warmed almost twice as quickly as the land over this time – a “puzzling observation given the ocean warms more slowly than land”, he says.
Dr Zeke Hausfather, Carbon Brief’s contributing science writer, adds that the study authors are “conflating ocean mixed layer temperature with sea surface temperature in a way that is confusing”. He adds that “their reconstruction also seems a bit at odds with other palaeoclimate reconstructions – such as PAGES2k – that do not see large differences in pre-1900 temperatures”.
The sclerosponge record
Coralline sclerosponges are an ancient type of calcifying sea sponge which can live for hundreds of years. As they grow, chemicals called strontium and calcium build up in their skeletons. The ratio of strontium to calcium in their skeletons is higher during warm periods and lower during cool periods.
Scientists collected live specimens of sclerosponge from the Caribbean sea and analysed the ratios of strontium to calcium in their skeletons to reproduce a timeseries of ocean temperatures in the region from the year 1700 to the present day.
Dr Amos Winter is a professor of Earth and environmental systems at Indiana State University and author on the study. He told the press briefing that there is no such thing as a “perfect proxy”, but said the sclerosponge record is “as good as possible – the holy grail of reconstruction”.
He explained that the Caribbean is “the ideal location to measure global trends”. According to the paper, the region is “ideally positioned” to have a “minimal” impact from the Atlantic Meridional Overturning Circulation, while “still registering the broader effects” of the El Niño-Southern Oscillation climate phenomenon.
He adds that the sclerosponge temperature reconstruction is “very robust” when compared to other assessments of temperature trends.
Dr Gavin Schmidt, director of the NASA Goddard Institute for Space Studies, says that the new data is a “useful addition to the database” of palaeoclimate proxies. However, he adds:
“Estimates of the global mean temperatures before 1850 require multiple proxies from as wide a regional variation as possible, thus claims that records from a single record can confidently define the global mean warming since the pre-industrial are probably overreaching.”
Prof Gabi Hegerl, a professor of climate system science at the University of Edinburgh, says that the paper presents a “nice new record” of ocean temperatures, but says that “the interpretation in terms of global warming goals overstretches it”.
She warns that “a single location cannot substitute global data, as climate varies across the globe, which is why the only way to measure global temperature is to get data from across the globe”.
Similarly, Hausfather calls the finding “interesting”, but says it “should be combined with other proxy records in a larger synthesis before it will change our prevailing views here”.

DeBriefed 3 July 2026: US faces scorching Independence Day | Record ocean temperatures | Vietnam’s EV surge
Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Heating up
NOT FREE FROM HEAT: “Dangerous, record-breaking” heat altered plans for 4 July celebrations across the US this weekend, reported the Associated Press. New York and Boston hit 100F (37.8C) on Thursday, said the newswire. CNBC reported that temperatures of up to 105F (40.5C) are forecast in central and eastern parts of the country, with “daily, monthly and all-time records possible”.
TEMPERATURES SOAR: Heat that hit western Europe last week spread east to “scorch” Germany, Hungary, Romania, Poland and others, said Bloomberg. Red warnings for extreme heat were issued in a number of nations, noted the outlet, adding that the heat “underscores how climate change is transforming summers in the world’s fastest-warming continent”. The Independent said last month was confirmed to be England’s hottest June on record.
HEAT DEATHS: June’s extreme temperatures caused more than 2,000 excess deaths in Spain and France, reported the Guardian. The countries are bracing for further heat that “could bring temperatures of 44C (111F) over the coming days”, said the newspaper. Deaths in France rose almost 30% at the heatwave “peak” on the week of 22 June, according to Le Monde. Last week’s conditions also led to around 480 excess deaths in the Netherlands, reported Reuters.
BOILING: Global ocean temperatures reached record levels for this time of year, reported NBC News, “fuelling fears of more dangerous heatwaves this summer and fanning concerns over the escalating global climate crisis”. Scientists told the Financial Times that this could lead the world towards “uncharted territory”. The newspaper said global average sea surface temperatures reached 20.96C on 21 June, exceeding June records for 2023 and 2024.
Around the world
- GOAL DROPPED: The World Bank will “abandon” its goal to devote 45% of annual lending resources to climate-related projects, reported Reuters. Carbon Brief explored what it could mean for global climate action.
- FIVE-YEAR PLAN: China plans to invest more than 20tn yuan ($2.9tn) in “key energy projects and new business models” over the next five years, according to International Energy Net.
- DRILLING: The Guardian said UK Labour politicians “urged” the likely next prime minister Andy Burnham to ignore “deluded” calls to develop the Rosebank oil field located in the Atlantic north of Scotland.
- PLASTIC TALKS: Countries and activists feared key issues could be sidelined at “critical” talks on a global treaty to curb plastic pollution in Kenya, said Climate Home News. A treaty could have “important implications” for climate change, reported Carbon Brief in 2024.
- CANADA PIPELINE: Canadian prime minister Mark Carney announced plans to build an oil pipeline to supply Asia with up to 1m barrels per day, reported the Financial Times. Earlier this week, Carney called the previous government’s climate plans “expensive” and “divisive”, said CBC News.

Captured
Wind and solar were the world’s largest source of new energy in 2025, according to Carbon Brief analysis of the latest Energy Institute statistical review of world energy. Wind and solar also saw the fastest growth, up by 18% in 2025. Nevertheless, every source of energy – including coal, oil, gas, nuclear and hydro – also reached global all-time highs last year.
Spotlight
Vietnam’s EV surge
Carbon Brief explores the reasons behind soaring electric-vehicle sales in Vietnam.
Motorbikes are a constant fixture on streets across Vietnam. They pollute the air in cities and make crossing the road a feat of endurance.
But, increasingly, people are moving away from petrol-powered vehicles to save money and reduce air pollution.
Sales of electric motorbikes, scooters and mopeds more than doubled in Vietnam last year, according to a recent report from the International Energy Agency (IEA).
This identified that Vietnam has the largest electric vehicle (EV) market in south-east Asia.
Nearly one-in-five of the two-wheeled vehicles sold last year were electric, it noted, in a nation with 102 million people and 77m motorbikes.
This is “particularly impactful” given they are the main mode of transport in Vietnam, said Lam Pham, Asia energy analyst at thinktank Ember. He told Carbon Brief:
“Electrifying road transport is essential for Vietnam to achieve its net-zero target by 2050. Road transport accounted for around 86% of transport-sector emissions in 2022.”
The nation has just 6.8m cars, but this number is also climbing, partly due to EVs, with nearly 40% of new car sales being electric.
This is “above levels seen in most European countries”, noted the IEA. (The UK’s figure is around 30%.)
EV incentives
Fuel costs surged in south-east Asian countries earlier this year after the energy crisis caused by the US-Israel war on Iran.
This “accelerated” discussions from “why use EVs” to “why keep paying more for fuel”, said Dr Tham Nguyen, a lecturer at the Ho Chi Minh City campus of Australia’s Royal Melbourne Institute of Technology (RMIT) University, who has researched Vietnamese public attitudes to EVs.
But the surge is “not driven by fuel prices alone”, noted Pham.
Increased EV sales can also be attributed to a “convergence of affordability, convenience and sustainability”, Nguyen said:
“Vietnamese consumers buy EVs because they see real value with immediate personal benefits, such as cost savings and energy security, alongside long-term environmental gains.”
Government policies have also incentivised sales through registration fee exemptions and tax cuts for EVs.
Another factor is affordable EVs sold by Chinese companies and Vinfast, a Vietnamese manufacturer. The IEA report noted that Vietnam is the only country in south-east Asia with “sizeable” domestic production of accessible EVs.
Vinfast reported a 219% year-on-year increase in orders for electric motorbikes and e-bikes in the first quarter of 2026, but the company has yet to turn a profit.
Pham noted that “growing public awareness of air pollution” has also “dramatically strengthened” public support for EVs.
Future plans
Vietnam’s major cities also have plans to get drivers to go electric or turn to public transport.
The capital city Hanoi announced that it would ban fossil-fuel-powered motorbikes from a central zone this month, but this has been postponed until 2028.
Ho Chi Minh City, the nation’s largest city with more than 9.5 million people, intends to introduce low-emission zones and swap 400,000 petrol-powered motorbikes to electric by 2028.
The city’s green transport plans focus on metro lines, electric buses and e-bikes, explained RMIT associate professor Catherine Earl. She noted that walking and cycling are currently “not popular, accessible or safe for many residents in Ho Chi Minh City’s hot and humid climate”.
Looking ahead, Pham said Vietnam could focus on “purchase subsidies, financing schemes and adequate charging or battery-swapping infrastructure, to ensure lower-income riders, including delivery and ride-hailing drivers, are not negatively affected”.

The post DeBriefed 3 July 2026: US faces scorching Independence Day | Record ocean temperatures | Vietnam’s EV surge appeared first on Carbon Brief.
The World Bank has abandoned a target for 45% of the funding it gives developing countries to be “climate finance”, following months of pressure from the Trump administration in the US.
However, a concerted effort by developed- and developing-country shareholders has seen the bank hold onto its “action plan” for tackling climate change.
The multilateral development bank (MDB) – which is headquartered in Washington DC – is the single largest provider of climate finance globally, distributing $39.2bn in 2025 alone, primarily as loans.
Amid widespread aid cuts by developed countries, the World Bank and other MDBs have previously pledged to significantly scale up their climate finance over the next decade.
Despite scrapping its central target, the bank says it will continue to support the demands of its “clients”, many of which have explicitly stated their need for climate-related investment.
Here, Carbon Brief looks at the likely impact of the World Bank’s policy shift and whether it is – as one expert puts it – “mostly a symbolic victory” for the US.
- How does the World Bank support climate action?
- Why has the World Bank abandoned its climate-finance target?
- Why is the World Bank important for international climate finance?
- How will these changes affect global climate action?
How does the World Bank support climate action?
The World Bank is the oldest and largest MDB. It is tasked by its 189 member governments – the bank’s shareholders – with supporting development projects around the world.
The US is the bank’s largest shareholder, followed, in order, by Japan, China, Germany, France and the UK.
Every year, the bank provides billions of dollars – predominantly as loans – to developing countries.
(One part of the World Bank, the International Development Association – IDA – specifically distributes grants to lower-income nations, as well as lower-interest loans.)
Through its financing, the World Bank also has an important role in “mobilising” private investments in developing countries.
In recent years, the bank has increasingly focused on helping developing countries to cut emissions and adapt their economies for climate change.
The World Bank provided $164bn in what it calls financing with climate “co-benefits” between 2020 and 2025.
The largest share of this funding – roughly one-fifth – went to clean energy and electricity access projects. Smaller shares went to areas such as public transport, water supply and sustainable farming.
As the map below shows, the largest recipients of the bank’s climate funds since 2020 have been emerging economies, such as Turkey ($10.3bn), India ($9bn) and Nigeria ($6.3bn).
Among the largest World Bank projects in recent years are two extensive programmes in India, totalling nearly $3bn, supporting renewables and green hydrogen.
Others include $1.7bn for a Pakistan hydropower project, $926m for Iraq’s railways and $803m to boost “green development” in Colombia.
Despite the bank’s major role in providing climate finance to developing countries, it has faced heavy scrutiny from climate advocates.
In particular, they have noted the dominance of loans that push developing countries further into debt. The World Bank has also been criticised for a lack of transparency around how it classifies projects as “climate-related”, as well as “over-reporting” of climate finance.
Why has the World Bank abandoned its climate-finance target?
When World Bank president Ajay Banga – nominated by former US president Joe Biden – took over the institution in 2023, there were widespread calls for MDB reform.
Many of the bank’s shareholders wanted to see billions more dollars being channelled to support climate action. Later that year, Banga announced that the bank would ensure that 45% of the bank’s funding was climate finance by 2025.
This replaced an existing target of 35% for climate finance between 2021 and 2025, which had been set out in the bank’s second climate change action plan (CCAP).
The CCAP is intended to “mainstream” climate action in the bank’s work. With it in place, the World Bank’s climate finance more than doubled from $17.2bn in 2020 to $39.2bn in 2025.
As the chart below shows, this meant the World Bank exceeded its 2025 goal, with climate-related projects making up a 48% share of total funding that year.
When Biden was replaced by Donald Trump as president in 2025, the US administration turned against international cooperation, including climate finance.
However, the US did not walk away from the World Bank, where it exerts considerable power as the largest shareholder.
With the CCAP due to expire in July 2026, the US has spent months pressuring the bank and its shareholders to weaken or abandon the plan altogether.
US Treasury secretary Scott Bessent issued a statement during the 2026 World Bank and International Monetary Fund (IMF) spring meetings in April 2026, in which he called for “jettisoning” the 45% climate-finance target. More broadly, he said:
“We welcome the coming expiration of the CCAP and…expect the bank to immediately shift its myopic focus on climate and financing volumes to one that emphasises high-quality, durable projects.”
This vision involves a push for the World Bank to finance more fossil-fuel projects, including drilling for new gas. (The bank has committed since 2019 to stop funding upstream oil and gas projects.)
The decision on whether to continue with the CCAP was negotiated behind closed doors by the board of directors – representing national shareholders. There were reports of “deep divides”.
A joint statement from 19 of the 25 directors last year affirmed the need for both a plan and a target. The US, Russia, Kuwait and Saudi Arabia all declined to sign up, while Japan and India abstained, according to Reuters.
There were reports of European nations championing a climate plan, bolstered by support from the developing countries that would stand to receive climate finance. The US call to drop the 45% target entirely was reportedly backed by Saudi Arabia and Russia.
Ultimately, the day before the CCAP was due to lapse, the World Bank announced what appeared to be a middle ground. It would drop both the 45% target and the 35% goal it had replaced, while also “extend[ing]” the CCAP.
UK development minister Jenny Chapman told a committee hearing in the House of Commons the next day that this marked a “compromise”. She said:
“It wasn’t clear we were going to get a CCAP at all and a bank without an action plan on climate is a problem for us – so that’s a good outcome.”
Supportive shareholders had been pushing for a one-year extension of the plan. While the World Bank did not initially define the length, Chapman confirmed on LinkedIn that the plan had, in fact, been extended “indefinitely”.
The bank said it would also engage an “independent evaluation group” to assess the CCAP, in line with a board request.
Gaia Larsen, director of climate finance at the World Resources Institute (WRI), tells Carbon Brief that this evaluation will likely be “relatively free from political ideology” and could be “focused on how to make the CCAP more effective”.
Why is the World Bank important for international climate finance?
Under the Paris Agreement, developed countries – including major World Bank shareholders in Europe and elsewhere – are obliged to provide climate finance for developing countries.
This includes a target of $300bn a year by 2035, which is expected to largely come from developed countries. One significant way these nations can contribute to this goal is via their support for MDBs, particularly the World Bank.
The World Bank has described itself as “by far the largest provider of climate finance to developing countries”. Each year, it oversees half of all climate finance from MDBs and far more than any single donor country.
Many developed countries have, therefore, enthusiastically backed the World Bank’s climate efforts, as well as a “bigger” role for MDBs in development more broadly. The bank can lend sums that far exceed the amount of new public finance that individual nations are willing to commit.
This is particularly significant, given many of these nations, including the UK, Germany and France, have announced large cuts to their aid budgets in recent years.
Carbon Brief analysis suggests that roughly a fifth of the international climate finance provided and “mobilised” by developed countries in recent years can be attributed to their World Bank contributions, as the chart below shows.
(This only accounts for the World Bank financing that can be linked to developed-country shares in the bank. Developing countries, such as China, also have significant shares, which are not included in the chart below.)
MDBs – including the World Bank – have committed to providing $120bn in climate finance to developing countries by 2030.
This was set to come from greater shareholder contributions, combined with a programme of reforms to free up capital.
If the World Bank continued to provide half of the MDB total, it would need to increase its climate finance by around 50%, from $39.2bn today to $60bn in 2030.
Therefore, experts see a “key” role for the World Bank in achieving not only the $300bn target, but also the more aspirational $1.3n target that countries agreed as part of the “new collective quantified goal” (NCQG) on climate finance at COP29 in 2024. This includes the private capital it could “unlock” through its lending.
Joe Thwaites, international climate finance director at Natural Resources Defense Council (NRDC), tells Carbon Brief that these “NCQG politics” are “quite important”. He says:
“The maths of the $300bn does not work if the MDBs pull back and so I think that’s why you’re seeing developed countries taking a stand.”
How will these changes affect global climate action?
To date, the World Bank has only released minimal details about its new climate plans. As such, experts say the impact on future climate finance remains uncertain.
Jon Sward, environment project manager at the Bretton Woods Project, tells Carbon Brief:
“They have said they are going to retain all the same processes about climate-finance reporting. So, of course, there is a world in which, actually, climate finance continues to increase like it has been.”
Some of the World Bank’s internal organisations will, in fact, keep their climate-finance goals for the time being. For example, the IDA’s largely grant-based funding retains a 45% target for its current round, which will last until 2028 – the year of the next US presidential election.
However, WRI’s Larsen tells Carbon Brief that the changes, from a bank that was previously a “champion for climate action”, remain significant:
“This reality, reinforced by the elimination of the 45% goal, means that it would not be surprising to see a reduction in climate investments.”
In a statement, the World Bank said its “work on climate is and will remain firmly client driven”, noting that it supports nations undertaking their Paris Agreement climate plans.
Therefore, its climate focus may come down to whether there is demand for climate action from “client” countries receiving finance.
At an April event in discussion with the climate sceptic Bjørn Lomborg, Bessent said that global financial institutions should focus on growth, characterising climate action as an “elite belief”.
The implication from the US Treasury secretary was that recipient countries are not interested in climate action. However, as reported by Devex, a group of World Bank shareholders representing nearly 100 developing countries, wrote a letter that appeared to push back against this framing.
This “G11+” group, led by Brazil and China, said the bank “must remain firmly client-driven”, noting that countries are “following nationally determined pathways toward climate action”. NRDC’s Thwaites tells Carbon Brief:
“It’s one thing for the Europeans to talk about climate…This was the client countries [100 developing countries] saying: ‘No, we want this.’”
Recent research by the ODI thinktank found that 79% of developing-country officials polled wanted to see MDB investment in solar projects, 54% wanted hydropower and 47% wanted wind power. Only 13% wanted investment in gas-power plants.
Rishikesh Ram Bhandary, a senior development researcher at Boston University, has stressed the need for an “enhanced CCAP”, which could be supported by the bank’s new independent evaluation. Among other things, he tells Carbon Brief:
“The bank needs to make a more convincing case about how climate change is being integrated into development priorities rather than competing with them.”
Thwaites says he is hopeful that the outcome is “mostly a symbolic victory for the US”.
However, he says major shareholders from Europe and elsewhere should make it clear to the bank that it is not “the only game in town” when it comes to climate finance. He says:
“If [the World Bank] are going to cave into one shareholder, when the vast majority of the other shareholders are supportive of continuing climate action, they can take their money elsewhere.”

Q&A: How will the World Bank’s abandoned finance goal affect climate action?
Rich Wilson is CEO of the Iswe Foundation and co-founder of the Global Citizens’ Assembly.
The numbers are stark. According to the 2026 Global Report on Food Crises, 266 million people across 47 countries experienced high levels of acute food insecurity last year, nearly double the figure recorded a decade ago.
Meanwhile, disruptions to oil, gas and fertiliser flows through the Strait of Hormuz drove a 46% month-on-month spike in urea prices early this year, sending agricultural price indices up 8% and raising the spectre of a global affordability crisis.
This is not a blip. It is a new baseline. The EAT-Lancet Commission concluded that food systems now account for roughly 30% of total greenhouse gas emissions and are the largest single contributor to the climate crisis. The science has been clear for years.
Now some of the solutions to the problem are becoming socially acceptable too.

Can giant batteries unlock Africa’s green industrial future?
Battery energy storage systems (BESS) could drive clean tech manufacturing in Africa but shortfalls in finance and data are still limiting deployment at scale
Earlier this year, people from more than 60 countries and territories, selected not by vested interest, but by lottery, spent seven weeks examining the evidence on food and climate for the latest Global Citizens’ Assembly. They heard from scientists, farmers and industry. They worked through 42 hours of structured deliberation, engaging with some difficult trade-offs.
They were not asked to endorse a predetermined conclusion. They were asked an open question: what changes, if any, should we make to how we grow, share and eat food, so that everyone has enough to nourish themselves while tackling the causes and impacts of climate change?
Phase down industrial animal farming
Their answer was unambiguous. They voted to protect forests. They voted to phase down industrial animal food production. They voted for supply chain reform and corporate accountability, explicitly rejecting the idea that the burden of change should fall on individual consumers. All 22 of their Calls to Action passed with over 85% support, a super-majority of randomly selected people from every region of the world, in agreement.
Consider what the assembly was actually being asked to decide. Industrial animal food production is the primary driver of tropical deforestation. Protecting more land as forest and ecosystem means less land available for the expansion of industrial production. That is a real trade-off, with real consequences for real livelihoods. Politicians have spent years avoiding it.
These randomly selected people looked at the evidence, deliberated across time zones and cultures, and chose the forests, with 64% in strong support and a further 20% in favour. People from livestock farming communities voted for change. Not because they were told to. Because deliberation led them there.
We estimate there have now been more than 7,000 citizen participation initiatives worldwide in the last decade. They have been organised because, as our 2025 report: People in the Lead demonstrated, people are now consistently and significantly ahead of politicians on issues ranging from climate to AI governance.
The people know best
What the research consistently shows is that ordinary people, given proper evidence and time, produce recommendations that are more effective and more aligned with public values than what emerges from elected legislatures. The gap in global governance is no longer primarily between science and the public. It is between citizens and their political leaders.
That gap matters for more than procedural reasons. When policy treats people as passive recipients rather than active participants, it leaves out the very actors whose behaviour, trust and consent the transition depends on. Institutions that speak only to other institutions, and negotiate only with state actors and industry lobbies, are missing out on the trust and energy of the people they are supposed to serve.
Governments, left to their own devices, are not moving fast enough to prove that argument wrong. At COP30 in Belém last November, countries failed to agree on a fossil fuel phaseout roadmap, and even full implementation of every submitted national climate plan still leaves the world on course for 2.3 to 2.8C of warming.
Citizens’ track at COP
But the Brazilian presidency grasped something important. Among the conference’s more significant outcomes was the formal launch of a Citizens’ Track within the UNFCCC process, a mechanism for connecting the global participation field to intergovernmental climate negotiations. Türkiye and Australia, who together hold the COP31 presidency in Antalya this November, now have the opportunity to strengthen and institutionalise what Brazil began.
In Guatemala, Indigenous women build climate resilience with old and new farming methods
The question before us is no longer whether citizens can contribute to solving these problems. Across the world, in local food networks, in community assemblies and in participatory planning processes, they already are, quietly generating more ambitious and more legitimate solutions than those emerging from formal diplomatic channels.
What is required now is the political courage to connect people to power. Not to consult citizens and file the results. Not to invite them to observe while the real decisions are made elsewhere. But to recognise the public as partners in perhaps the most consequential governance challenge of our time.
