Nearly a decade on from the Paris Agreement, there is still not an agreed way to measure progress towards its “global goal on adaptation” (GGA).
Yet climate impacts are increasingly being felt around the world, with the weather becoming more extreme and the risk to vulnerable populations growing.
At COP30, which takes place next month, negotiators are set to finalise a list of indicators that can be used to measure progress towards the GGA.
This is expected to be one of the most significant negotiated outcomes from the UN climate summit in Belém, Brazil.
In a series of open letters running up to the summit, COP30 president-designate André Corrêa do Lago wrote that adaptation was “no longer a choice” and that countries needed to seize a “window of opportunity”:
“There is a window of opportunity to define a robust framework to track collective progress on adaptation. This milestone will…lay the groundwork for the future of the adaptation agenda.”
However, progress on producing an agreed list of indicators has been difficult, with nearly 90 experts working over two years to narrow down a list of almost 10,000 potential indicators to a final set of just 100, which is supposed to be adopted at COP30.
Below, Carbon Brief explores what the GGA is, why progress on adaptation has been so challenging and what a successful outcome would look like in Belém.
What is the GGA?
The GGA was signed into being within the Paris Agreement in 2015, but the treaty included limited detail on exactly what the goal would look like, how it would be achieved and how progress would be tracked.
The need to adapt to climate change has long been established, with the UN Framework Convention on Climate Change, adopted in 1992, noting that parties “shall…cooperate in preparing for adaptation to the impacts of climate change”.
In the subsequent years, the issue received limited focus, however. Then, in 2013, the African Group of Negotiators put forward a proposed GGA, setting out a target for adaptation.
This was then formally established under article 7.1 of the Paris text two years later. The text of the treaty says that the GGA is to “enhanc[e] adaptive capacity, strengthen…resilience and reduc[e] vulnerability to climate change”.
According to the World Resources Institute (WRI), the GGA was designed to set “specific, measurable targets and guidelines for global adaptation action, as well as enhancing adaptation finance and other types of support for developing countries”.
However, unlike the goal to cut emissions – established in article 4 of the Paris Agreement – measuring progress on adaptation is “inherently challenging”.
Emilie Beauchamp, lead for monitoring, evaluation and learning (MEL) for adaptation at the International Institute for Sustainable Development (IISD), tells Carbon Brief that this challenge relates to the context-specific nature of what adaptation means. She says:
“The main [reason] it’s hard to measure progress on adaptation is because adaptation is very contextual, and so resilience and adapting mean different things to different people, and different things in different places. So it’s not always easy to quantify or qualify…You need to integrate really different dimensions and different lived experiences when you assess progress on adaptation. And that’s why it’s been hard.”
Beyond this, attribution of the impact of adaptive measures remains a “persistent challenge”, according to Dr Portia Adade Williams, a research scientist at the CSIR-Science and Technology Policy Research Institute and Carbon Brief contributing editor, “as observed changes in vulnerability or resilience may result from multiple climatic and non-climatic factors”. She adds:
“In many contexts, data limitations and inconsistent monitoring systems, particularly in developing countries, constrain systematic tracking of adaptation efforts. Existing monitoring frameworks tend to emphasise outputs, such as infrastructure built or trainings conducted, rather than outcomes that reflect actual reductions in vulnerability or enhanced resilience.”
Despite these challenges, the need for increased progress on adaptation is clear. Nearly half of the global population – around 3.6 billion people – are currently highly vulnerable to these impacts. This includes vulnerability to droughts, floods, heat stress and food insecurity.
However, for six years following the adoption of the Paris Agreement, the GGA did not feature on the agenda at COP summits and there was limited progress on the matter.
This changed in 2021, at COP26 in Glasgow, when parties initiated the two-year Glasgow-Sharm el-Sheikh work program to begin establishing tangible adaptation targets.
This work culminated at COP28 in Dubai, United Arab Emirates, with the GGA “framework”.
Agreeing the details of this framework and developing indicators to measure adaptation progress has been the main focus of negotiations in recent years.
What progress has been made?
Following the establishment of the GGA, there was – for many years – only limited progress towards agreeing how to track countries’ adaptation efforts.
COP28 was seen as a “pivotal juncture” for the GGA, with the creation of the framework and a new two-year plan to develop indicators, which is supposed to culminate at COP30.
Negotiations across the two weeks in Dubai in 2023 were tense. It took five days for a draft negotiating text on the GGA framework to emerge, due to objections from the G77 and China group of developing countries around the inclusion of adaptation finance.
Within the GGA – as with many negotiating tracks under the UNFCCC – finance to support developing nations is a common sticking point. Other disagreements included the principle of “common but differentiated responsibilities and respective capabilities” (CBDR–RC).
Ultimately, a text containing weakened language around both CBDR-RC and finance was waved through at the end of COP28 and a framework for the GGA was adopted.
Speaking to Carbon Brief, Ana Mulio Alvarez, a researcher on adaptation at thinktank E3G, said that the framework was the “first real step to fulfilling” the adaptation mandate laid out in the Paris Agreement, adding:
“The GGA is the equivalent of the 1.5C commitment for mitigation – a north star to guide efforts. It will be hugely symbolic if the GGA indicators are agreed at COP and the GGA can be implemented.”
The framework agreed at COP28 includes 11 targets to guide progress against the GGA. Of these, four are related to what it describes as an “iterative adaptation cycle” – risk assessment, planning, implementation and learning – and seven to thematic targets.
These “themes” cover water, food, health, ecosystems, infrastructure, poverty eradication and cultural heritage.
Within these, there are subgoals for countries to work towards. For example, within the water theme, there is a subgoal of achieving universal access to clean water.
While this framework was broadly welcomed as a step forward for adaptation work, there remains concern from some experts about the focus of the programme.
Prof Lisa Schipper, a professor of development geography at the University of Bonn, Intergovernmental Panel on Climate Change (IPCC) author and Carbon Brief contributing editor, tells Carbon Brief that without the framework there would likely have been continued delays, but there was still “significant scientific pushback against this approach to adaptation”.
She notes that the IPCC’s sixth assessment report (AR6) “didn’t necessarily provide any concrete inputs that could be useful for the GGA”. Beyond this, there are political challenges that the framework does not address, Schipper adds, continuing:
“There are also political reasons why global-north countries or annex-one countries don’t necessarily want specificity [in adaptation targets], because they also don’t want to be held accountable and to be forced to pay for things, right? So, the science was pathetic in one way, it was just not sufficient. And then you have a political agenda that’s fighting against clarity on this.
“So, even though [the framework] came together, it was still not very concrete, right? It was a framework, but it didn’t have a lot in it.”
As with the language around finance, thematic targets within the GGA were weakened over the course of the negotiations. Additionally, parties ultimately did not agree to set up a specific, recurring agenda item to continue discussing the GGA.
However, a further two-year programme was established at COP28. The UAE-Belém work programme was designed to establish concrete “indicators” that can be used to measure progress on adaptation going forward.
Why is it hard to choose adaptation indicators?
In the two years following COP28, work has been ongoing to narrow down a potential list of more than 9,000 indicators under the GGA to just 100.
At the UNFCCC negotiations in June 2024 in Bonn, parties agreed to ask for a group of technical experts to be convened to help with this process.
This led to a group of 78 experts meeting in September 2024. They were split into eight working groups – one for each of the seven themes and one for the iterative adaptation cycle – to begin work reviewing a list of more than 5,000 indicators, which had already been compiled from submissions to the UNFCCC.
In October 2024, a second workshop was held under the UAE-Belém work programme, at which the experts agreed that they should also consider an additional 5,000 indicators compiled by the Adaptation Committee, another body within the UN climate regime.
One key challenge, Beauchamp tells Carbon Brief, was that the group of experts had very limited time and a lack of resources. She expands:
“They had to finish their work by the end of the summer [of 2025]. This means they’ve not even had a year [and] they have no funding. So of the 78 experts, the number of whom could actually contribute was much lower, and it’s not by lack of desire and expertise. But [because] they have day jobs, they have families…And the lack of clear instructions from parties also didn’t help.”
COP29 formed the mid-way point in the work programme to develop adaptation indicators, with parties stressing it was “critical” to come away with a decision from the summit.
As with previous sessions, finance quickly became a sticking point in negotiations, however, alongside the notion of “transformational adaptation”.
This is a complex concept centred around the idea of driving systemic shifts – in infrastructure, governance or society more broadly – so as to address the root causes of vulnerability to climate change.
Ultimately, COP29 adopted a decision that made reference to finance as “means of implementation” (MOI), recognised transformational adaptation and launched the Baku Adaptation Roadmap (BAR). The BAR is designed to advance progress towards the GGA, however, the details of how it will operate are still unclear.
Going into the Bonn climate negotiations in June 2025, the list of potential indicators had been “miraculously” refined to a list of 490 through further work by the group of experts. While this was a major step forward, it was still a long way off the aim of agreeing to a final set of just 100 indicators at COP30.
Once again, disagreement quickly arose in Bonn around finance and this dominated much of the two weeks of negotiations. As such, a final text did not get uploaded until mid-way through the final plenary meeting of the negotiations.
This was seen as contentious, as some parties complained that they did not have time to fully assess it, before it was gavelled through.
Bethan Laughlin, senior policy specialist at the Zoological Society of London, tells Carbon Brief:
“Adaptation finance has consistently lagged behind mitigation for decades, despite growing recognition of the urgent need to build resilience to climate shocks. The gap between the needs of countries and the funding provided is stark, with an adaptation financing gap in the hundreds of billions annually.
“Within the GGA negotiations, the implications of this finance issue are clear. Disagreements persist over how MoI [finance] should be measured in the indicator set, particularly around whether private finance should count, how support from developed countries is defined, and how national budgets are tracked versus international climate finance.”
The final text produced in Bonn was split into two, with an agreed section capturing the GGA indicators and a separate “informal note” covering the BAR and transformation adaptation.
Importantly, the main text invited the experts to continue working on the indicators and to submit a final technical report with a list of potential indicators by August 2025.
As this work continued, one of the biggest challenges was “balancing technical rigour with political feasibility while ensuring ambition”, says Laughlin, adding:
“The scale and diversity of adaptation action means a diverse menu of indicators per target is needed, but this must not be so vast as to be unfeasible for countries to measure, especially those countries with limited resources and capacity.”
Meetings took place subsequently, within which experts focused on “ensuring adaptation relevance of indicators, reducing redundancy and ensuring coverage across thematic indicators”, according to a technical report.
Beauchamp notes the importance of these themes for continued work on adaptation, saying:
“The themes were really helpful to bring some attention and to communicate about the GGA. They echo more easily what adaptation results can look like, because people find it difficult to talk about processes. But they’re really important. Without the targets on the adaptation cycle, we can too easily forget that you need resilient processes to have resilient outcomes.”
The table below, from the same technical report, shows how nearly 10,000 adaptation indicators have been whittled down to a proposed final list of 100. The table also shows how the indicators are split between the themes (9a-g) and iterative adaptation cycle (10a-d) of the GGA framework.

Further consultations took place in September and the final workshop under the UAE-Belém work programme took place on 3-4 October.
Following on from the numerous sessions held under the GGA, negotiators are now able to go into COP30 with a consolidated list of indicators to discuss, agree and bring into use, allowing progress towards the adaptation goal in Paris to be finally measured.
What to expect from COP30?
A final decision on the adaptation indicators is expected at COP30, potentially marking a significant milestone under the GGA.
In his third letter, COP30 president-designate Correa do Lago noted that a “special focus” was to be given to the GGA indicators at the summit.
He wrote that adaptation is “the visible face of the global response to climate change” and a “central pillar for aligning climate action with sustainable development”.
Therefore, he said COP30 should focus on “delivering tangible benefits for societies, ecosystems and economies by advancing and concluding the key mandates in this agenda”. These “key mandates” are the GGA and the related topic of National Adaptation Plans (NAPs).
Correa do Lago’s letter added:
“There is a window of opportunity to define a robust framework to track collective progress on adaptation. This milestone will also lay the groundwork for the future of the adaptation agenda.”
Indeed, adaptation has moved up the political agenda this year, with the topic being discussed during the “climate day” at the UN general assembly in September. This included a “leaders’ dialogue” on the sidelines of the assembly, where Carbon Brief understands that leaders of climate-vulnerable nations pushed for specific adaptation targets.
Elsewhere, nearly three-quarters (73%) of new country climate pledges include adaptation components, further emphasising the increased focus the topic is now receiving.
Despite the increased attention, there are still likely to be challenges at COP30, including the continued fight over finance. This will likely be felt particularly keenly, given that the COP26 commitment to double adaptation finance comes to an end this year.
This was part of the “Glasgow dialogue”, which saw parties commit to “at least double” adaptation finance between 2019 and 2025.
Adade Williams tells Carbon Brief:
“A major expectation [at COP30] is that parties will tackle the gaps in adaptation finance, consider how to link MoI – finance, technology, capacity‐building – with the GGA indicators and possibly set new finance ambitions or roadmaps. The emphasis on MoI means capacity building, data systems, technology transfer and institutional strengthening will gain more traction.”
Adaptation finance was also a key topic during pre-COP meetings in Brasilia in October, with E3G noting that it is a “political litmus test for success in Belém, with vulnerable countries signalling urgency and demanding greater clarity that finance will flow”.
Laughlin tells Carbon Brief that she expects discussions on finance to “dominate in Belém” – in particular, given the legacy of the “new collective quantified goal” (NCQG) for climate finance agreed at COP29, which many developing countries were “starkly disappointed” by.
Additionally, there may be challenges around the process of negotiations on the GGA indicators, notes Beauchamp, adding:
“We’ve not agreed yet if it is acceptable to open up text of some indicators [to negotiation]. We have 100 of them and, as a technical expert, on one hand [it] is quite worrying, because changing one term in an indicator can change its entire methodology, right? But, at the same time, there is definitely more work that can be done on the indicators.
“So, are we only keeping indicators that can work or that everybody is happy with now, and then we review the set later, for example, with the review of the UAE framework in 2028? Or do we open the whole Pandora’s box and then we start hashing out some new indicators? That’s the first big challenge parties need to grapple with at COP30.”
Despite the challenges, Mulio Alvarez says she would expect a final list of indicators to be adopted at COP30, even if some change during the negotiation process. She adds:
“The Brazilian presidency knows that this is the biggest negotiated outcome of COP30 and they want it to go through smoothly. The adoption of the list would officially launch the UAE framework so that it can begin to track and guide efforts.”
While agreement on indicators would be seen as a political win at COP30, several experts highlighted that it is only a step towards enabling further adaptation work, with Beauchamp noting that parties “need to see this as an opportunity”.
Laughlin adds:
“Although finalising the indicator list is a core deliverable, it is also important that COP30 makes progress on the next steps for the GGA following COP30, including the expectations for reporting, and regular updates to the indicator list so it keeps up with the latest science.”
What will the GGA mean for vulnerable communities?
COP30 kicks off on 10 November and negotiators are hoping to hit the ground running with the condensed list of indicators to discuss.
There remain key questions about what the GGA could mean for adaptation around the world – in particular, for those most vulnerable to the impacts of climate change.
Speaking to Carbon Brief, Mulio Alvarez notes:
“In the short term, the GGA metrics [indicators] will likely paint a very challenging picture of the needs for adaptation. In the medium to long term, we hope the GGA will be embedded in policy planning and implementation – supporting risk assessments, helping identify gaps, driving planning and resources and even unlocking investments.”
Others are more cautious about the potential impact of the GGA, the associated framework and its indicators, in terms of driving real progress for adaptation.
Schipper notes that, while the GGA indicators are welcome from a political perspective, “from a scientific perspective, and I think from a development perspective, I think there’s a sort of a high risk that this ends up making people worse off in the end”.
She adds that the incremental approach currently being taken for adaptation is not working and that the indicators can “at best” show us incremental progress.
Schipper notes that there is a risk that the indicators narrow the approach to adaptation to the extent that they are either ineffective or actually produce maladaptive outcomes. She adds:
“I’m not saying that we should abandon the indicators, but I think it’s important to recognise that this is not enough. This is nowhere near enough.”
Others are more optimistic about the long-term potential of the GGA. Laughlin suggests that the indicators could help build systemic resilience, adding that if they were successfully implemented it could mean adaptation is integrated into national development and planning, “making sure that climate resilience becomes a core part of policymaking”. She says:
“For vulnerable populations, this means moving from a reactive approach to a proactive one – embedding resilience into development planning, restoring ecosystems and empowering local communities.
“The success of the GGA in delivering for vulnerable populations hinges on political will, finance and inclusive governance – many of which are currently lacking.”
Beyond COP30, the GGA framework agreed at COP28 includes a number of overarching targets to help guide countries in developing and implementing their NAPs, although these targets are not quantified.
The targets include countries conducting risk assessments to identify the impact of climate change and areas of particular vulnerability, by 2030. The framework says this would inform a country’s NAP and that “by 2030 all parties have in place” adaptation planning processes or strategies, as shown in the image below.
Adade Williams tells Carbon Brief that if the GGA is “effectively implemented” it could help develop systemic resilience in the long term, helping to address “not just climate hazards but also underlying structural vulnerabilities”. She adds:
“However, this long-term potential depends heavily on the extent of political will, sustained finance and capacity support available to developing countries. Without these, the GGA risks becoming a reporting framework rather than a transformative mechanism for resilience.”

Key developments
Food inflation on the rise
DELUGE STRIKES FOOD: Extreme rainfall and flooding across the Mediterranean and north Africa has “battered the winter growing regions that feed Europe…threatening food price rises”, reported the Financial Times. Western France has “endured more than 36 days of continuous rain”, while farmers’ associations in Spain’s Andalusia estimate that “20% of all production has been lost”, it added. Policy expert David Barmes told the paper that the “latest storms were part of a wider pattern of climate shocks feeding into food price inflation”.

NO BEEF: The UK’s beef farmers, meanwhile, “face a double blow” from climate change as “relentless rain forces them to keep cows indoors”, while last summer’s drought hit hay supplies, said another Financial Times article. At the same time, indoor growers in south England described a 60% increase in electricity standing charges as a “ticking timebomb” that could “force them to raise their prices or stop production, which will further fuel food price inflation”, wrote the Guardian.
‘TINDERBOX’ AND TARIFFS: A study, covered by the Guardian, warned that major extreme weather and other “shocks” could “spark social unrest and even food riots in the UK”. Experts cited “chronic” vulnerabilities, including climate change, low incomes, poor farming policy and “fragile” supply chains that have made the UK’s food system a “tinderbox”. A New York Times explainer noted that while trade could once guard against food supply shocks, barriers such as tariffs and export controls – which are being “increasingly” used by politicians – “can shut off that safety valve”.
El Niño looms
NEW ENSO INDEX: Researchers have developed a new index for calculating El Niño, the large-scale climate pattern that influences global weather and causes “billions in damages by bringing floods to some regions and drought to others”, reported CNN. It added that climate change is making it more difficult for scientists to observe El Niño patterns by warming up the entire ocean. The outlet said that with the new metric, “scientists can now see it earlier and our long-range weather forecasts will be improved for it.”
WARMING WARNING: Meanwhile, the US Climate Prediction Center announced that there is a 60% chance of the current La Niña conditions shifting towards a neutral state over the next few months, with an El Niño likely to follow in late spring, according to Reuters. The Vibes, a Malaysian news outlet, quoted a climate scientist saying: “If the El Niño does materialise, it could possibly push 2026 or 2027 as the warmest year on record, replacing 2024.”
CROP IMPACTS: Reuters noted that neutral conditions lead to “more stable weather and potentially better crop yields”. However, the newswire added, an El Niño state would mean “worsening drought conditions and issues for the next growing season” to Australia. El Niño also “typically brings a poor south-west monsoon to India, including droughts”, reported the Hindu’s Business Line. A 2024 guest post for Carbon Brief explained that El Niño is linked to crop failure in south-eastern Africa and south-east Asia.
News and views
- DAM-AG-ES: Several South Korean farmers filed a lawsuit against the country’s state-owned utility company, “seek[ing] financial compensation for climate-related agricultural damages”, reported United Press International. Meanwhile, a national climate change assessment for the Philippines found that the country “lost up to $219bn in agricultural damages from typhoons, floods and droughts” over 2000-10, according to Eco-Business.
- SCORCHED GRASS: South Africa’s Western Cape province is experiencing “one of the worst droughts in living memory”, which is “scorching grass and killing livestock”, said Reuters. The newswire wrote: “In 2015, a drought almost dried up the taps in the city; farmers say this one has been even more brutal than a decade ago.”
- NOUVELLE VEG: New guidelines published under France’s national food, nutrition and climate strategy “urged” citizens to “limit” their meat consumption, reported Euronews. The delayed strategy comes a month after the US government “upended decades of recommendations by touting consumption of red meat and full-fat dairy”, it noted.
- COURTING DISASTER: India’s top green court accepted the findings of a committee that “found no flaws” in greenlighting the Great Nicobar project that “will lead to the felling of a million trees” and translocating corals, reported Mongabay. The court found “no good ground to interfere”, despite “threats to a globally unique biodiversity hotspot” and Indigenous tribes at risk of displacement by the project, wrote Frontline.
- FISH FALLING: A new study found that fish biomass is “falling by 7.2% from as little as 0.1C of warming per decade”, noted the Guardian. While experts also pointed to the role of overfishing in marine life loss, marine ecologist and study lead author Dr Shahar Chaikin told the outlet: “Our research proves exactly what that biological cost [of warming] looks like underwater.”
- TOO HOT FOR COFFEE: According to new analysis by Climate Central, countries where coffee beans are grown “are becoming too hot to cultivate them”, reported the Guardian. The world’s top five coffee-growing countries faced “57 additional days of coffee-harming heat” annually because of climate change, it added.
Spotlight
Nature talks inch forward
This week, Carbon Brief covers the latest round of negotiations under the UN Convention on Biological Diversity (CBD), which occurred in Rome over 16-19 February.
The penultimate set of biodiversity negotiations before October’s Conference of the Parties ended in Rome last week, leaving plenty of unfinished business.
The CBD’s subsidiary body on implementation (SBI) met in the Italian capital for four days to discuss a range of issues, including biodiversity finance and reviewing progress towards the nature targets agreed under the Kunming-Montreal Global Biodiversity Framework (GBF).
However, many of the major sticking points – particularly around finance – will have to wait until later this summer, leaving some observers worried about the capacity for delegates to get through a packed agenda at COP17.
The SBI, along with the subsidiary body on scientific, technical and technological advice (SBSTTA) will both meet in Nairobi, Kenya, later this summer for a final round of talks before COP17 kicks off in Yerevan, Armenia, on 19 October.
Money talks
Finance for nature has long been a sticking point at negotiations under the CBD.
Discussions on a new fund for biodiversity derailed biodiversity talks in Cali, Colombia, in autumn 2024, requiring resumed talks a few months later.
Despite this, finance was barely on the agenda at the SBI meetings in Rome. Delegates discussed three studies on the relationship between debt sustainability and implementation of nature plans, but the more substantive talks are set to take place at the next SBI meeting in Nairobi.
Several parties “highlighted concerns with the imbalance of work” on finance between these SBI talks and the next ones, reported Earth Negotiations Bulletin (ENB).
Lim Li Ching, senior researcher at Third World Network, noted that tensions around finance permeated every aspect of the talks. She told Carbon Brief:
“If you’re talking about the gender plan of action – if there’s little or no financial resources provided to actually put it into practice and implement it, then it’s [just] paper, right? Same with the reporting requirements and obligations.”
Monitoring and reporting
Closely linked to the issue of finance is the obligations of parties to report on their progress towards the goals and targets of the GBF.
Parties do so through the submission of national reports.
Several parties at the talks pointed to a lack of timely funding for driving delays in their reporting, according to ENB.
A note released by the CBD Secretariat in December said that no parties had submitted their national reports yet; by the time of the SBI meetings, only the EU had. It further noted that just 58 parties had submitted their national biodiversity plans, which were initially meant to be published by COP16, in October 2024.
Linda Krueger, director of biodiversity and infrastructure policy at the environmental not-for-profit Nature Conservancy, told Carbon Brief that despite the sparse submissions, parties are “very focused on the national report preparation”. She added:
“Everybody wants to be able to show that we’re on the path and that there still is a pathway to getting to 2030 that’s positive and largely in the right direction.”

Cropped 25 February 2026: Food inflation strikes | El Niño looms | Biodiversity talks stagnate
Rising temperatures across France since the mid-1970s is putting Tour de France competitors at “high risk”, according to new research.
The study, published in Scientific Reports, uses 50 years of climate data to calculate the potential heat stress that athletes have been exposed to across a dozen different locations during the world-famous cycling race.
The researchers find that both the severity and frequency of high-heat-stress events have increased across France over recent decades.
But, despite record-setting heatwaves in France, the heat-stress threshold for safe competition has rarely been breached in any particular city on the day the Tour passed through.
(This threshold was set out by cycling’s international governing body in 2024.)
However, the researchers add it is “only a question of time” until this occurs as average temperatures in France continue to rise.
The lead author of the study tells Carbon Brief that, while the race organisers have been fortunate to avoid major heat stress on race days so far, it will be “harder and harder to be lucky” as extreme heat becomes more common.
‘Iconic’
The Tour de France is one of the world’s most storied cycling races and the oldest of Europe’s three major multi-week cycling competitions, or Grand Tours.
Riders cover around 3,500 kilometres (km) of distance and gain up to nearly 55km of altitude over 21 stages, with only two or three rest days throughout the gruelling race.
The researchers selected the Tour de France because it is the “iconic bike race. It is the bike race of bike races,” says Dr Ivana Cvijanovic, a climate scientist at the French National Research Institute for Sustainable Development, who led the new work.
Heat has become a growing problem for the competition in recent years.
In 2022, Alexis Vuillermoz, a French competitor, collapsed at the finish line of the Tour’s ninth stage, leaving in an ambulance and subsequently pulling out of the race entirely.
Two years later, British cyclist Sir Mark Cavendish vomited on his bike during the first stage of the race after struggling with the 36C heat.
The Tour also makes a good case study because it is almost entirely held during the month of July and, while the route itself changes, there are many cities and stages that are repeated from year to year, Cvijanovic adds.
‘Have to be lucky’
The study focuses on the 50-year span between 1974 and 2023.
The researchers select six locations across the country that have commonly hosted the Tour, from the mountain pass of Col du Tourmalet, in the French Pyrenees, to the city of Paris – where the race finishes, along the Champs-Élysées.
These sites represent a broad range of climatic zones: Alpe d’ Huez, Bourdeaux, Col du Tourmalet, Nîmes, Paris and Toulouse.
For each location, they use meteorological reanalysis data from ERA5 and radiant temperature data from ERA5-HEAT to calculate the “wet-bulb globe temperature” (WBGT) for multiple times of day across the month of July each year.
WBGT is a heat-stress index that takes into account temperature, humidity, wind speed and direct sunlight.
Although there is “no exact scientific consensus” on the best heat-stress index to use, WBGT is “one of the rare indicators that has been originally developed based on the actual human response to heat”, Cvijanovic explains.
It is also the one that the International Cycling Union (UCI) – the world governing body for sport cycling – uses to assess risk. A WBGT of 28C or higher is classified as “high risk” by the group.
WBGT is the “gold standard” for assessing heat stress, says Dr Jessica Murfree, director of the ACCESS Research Laboratory and assistant professor at the University of North Carolina at Chapel Hill.
Murfree, who was not involved in the new study, adds that the researchers are “doing the right things by conducting their science in alignment with the business practices that are already happening”.
The researchers find that across the 50-year time period, WBGT has been increasing across the entire country – albeit, at different rates. In the north-west of the country, WBGT has increased at an average rate of 0.1C per decade, while in the southern and eastern parts of the country, it has increased by more than 0.5C per decade.
The maps below show the maximum July WBGT for each decade of the analysis (rows) and for hourly increments of the late afternoon (columns). Lower temperatures are shown in lighter greens and yellows, while higher temperatures are shown in darker reds and purples.
Six Tour de France locations analysed in the study are shown as triangles on the maps (clockwise from top): Paris, Alpe d’ Huez, Nîmes, Toulouse, Col du Tourmalet and Bordeaux.
The maps show that the maximum WBGT temperature in the afternoon has surpassed 28C over almost the entire country in the last decade. The notable exceptions to this are the mountainous regions of the Alps and the Pyrenees.
The researchers also find that most of the country has crossed the 28C WBGT threshold – which they describe as “dangerous heat levels” – on at least one July day over the past decade. However, by looking at the WBGT on the day the Tour passed through any of these six locations, they find that the threshold has rarely been breached during the race itself.
For example, the research notes that, since 1974, Paris has seen a WBGT of 28C five times at 3pm in July – but that these events have “so far” not coincided with the cycling race.
The study states that it is “fortunate” that the Tour has so far avoided the worst of the heat-stress.
Cvijanovic says the organisers and competitors have been “lucky” to date. She adds:
“It has worked really well for them so far. But as the frequency of these [extreme heat] events is increasing, it will be harder and harder to be lucky.”
Dr Madeleine Orr, an assistant professor of sport ecology at the University of Toronto who was not involved in the study, tells Carbon Brief that the paper was “really well done”, noting that its “methods are good [and its] approach was sound”. She adds:
“[The Tour has] had athletes complain about [the heat]. They’ve had athletes collapse – and still those aren’t the worst conditions. I think that that says a lot about what we consider safe. They’ve still been lucky to not see what unsafe looks like, despite [the heat] having already had impacts.”
Heat safety protocols
In 2024, the UCI set out its first-ever high temperature protocol – a set of guidelines for race organisers to assess athletes’ risk of heat stress.
The assessment places the potential risk into one of five categories based on the WBGT, ranging from very low to high risk.
The protocol then sets out suggested actions to take in the event of extreme heat, ranging from having athletes complete their warm-ups using ice vests and cold towels to increasing the number of support vehicles providing water and ice.
If the WBGT climbs above the 28C mark, the protocol suggests that organisers modify the start time of the stage, adapt the course to remove particularly hazardous sections – or even cancel the race entirely.
However, Orr notes that many other parts of the race, such as spectator comfort and equipment functioning, may have lower temperatures thresholds that are not accounted for in the protocol, but should also be considered.
Murfree points out that the study’s findings – and the heat protocol itself – are “really focused on adaptation, rather than mitigation”. While this is “to be expected”, she tells Carbon Brief:
“Moving to earlier start times or adjusting the route specifically to avoid these locations that score higher in heat stress doesn’t stop the heat stress. These aren’t climate preventative measures. That, I think, would be a much more difficult conversation to have in the research because of the Tour de France’s intimate relationship with fossil-fuel companies.”

DeBriefed 20 February 2026: EU’s ‘3C’ warning | Endangerment repeal’s impact on US emissions | ‘Tree invasion’ fuelled South America’s fires
Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Preparing for 3C
NEW ALERT: The EU’s climate advisory board urged countries to prepare for 3C of global warming, reported the Guardian. The outlet quoted Maarten van Aalst, a member of the advisory board, saying that adapting to this future is a “daunting task, but, at the same time, quite a doable task”. The board recommended the creation of “climate risk assessments and investments in protective measures”.
‘INSUFFICIENT’ ACTION: EFE Verde added that the advisory board said that the EU’s adaptation efforts were so far “insufficient, fragmented and reactive” and “belated”. Climate impacts are expected to weaken the bloc’s productivity, put pressure on public budgets and increase security risks, it added.
UNDERWATER: Meanwhile, France faced “unprecedented” flooding this week, reported Le Monde. The flooding has inundated houses, streets and fields and forced the evacuation of around 2,000 people, according to the outlet. The Guardian quoted Monique Barbut, minister for the ecological transition, saying: “People who follow climate issues have been warning us for a long time that events like this will happen more often…In fact, tomorrow has arrived.”
IEA ‘erases’ climate
MISSING PRIORITY: The US has “succeeded” in removing climate change from the main priorities of the International Energy Agency (IEA) during a “tense ministerial meeting” in Paris, reported Politico. It noted that climate change is not listed among the agency’s priorities in the “chair’s summary” released at the end of the two-day summit.
US INTERVENTION: Bloomberg said the meeting marked the first time in nine years the IEA failed to release a communique setting out a unified position on issues – opting instead for the chair’s summary. This came after US energy secretary Chris Wright gave the organisation a one-year deadline to “scrap its support of goals to reduce energy emissions to net-zero” – or risk losing the US as a member, according to Reuters.
Around the world
- ISLAND OBJECTION: The US is pressuring Vanuatu to withdraw a draft resolution supporting an International Court of Justice ruling on climate change, according to Al Jazeera.
- GREENLAND HEAT: The Associated Press reported that Greenland’s capital Nuuk had its hottest January since records began 109 years ago.
- CHINA PRIORITIES: China’s Energy Administration set out its five energy priorities for 2026-2030, including developing a renewable energy plan, said International Energy Net.
- AMAZON REPRIEVE: Deforestation in the Brazilian Amazon has continued to fall into early 2026, extending a downward trend, according to the latest satellite data covered by Mongabay.
- GEZANI DESTRUCTION: Reuters reported the aftermath of the Gezani cyclone, which ripped through Madagascar last week, leaving 59 dead and more than 16,000 displaced people.

Captured
Repealing the US’s landmark “endangerment finding”, along with actions that rely on that finding, will slow the pace of US emissions cuts, according to Rhodium Group visualised by Carbon Brief. US president Donald Trump last week formally repealed the scientific finding that underpins federal regulations on greenhouse gas emissions, although the move is likely to face legal challenges. Data from the Rhodium Group, an independent research firm, shows that US emissions will drop more slowly without climate regulations. However, even with climate regulations, emissions are expected to drop much slower under Trump than under the previous Joe Biden administration, according to the analysis.

How a ‘tree invasion’ helped to fuel South America’s fires
This week, Carbon Brief explores how the “invasion” of non-native tree species helped to fan the flames of forest fires in Argentina and Chile earlier this year.
Since early January, Chile and Argentina have faced large-scale and deadly wildfires, including in Patagonia, which spans both countries.
These fires have been described as “some of the most significant and damaging in the region”, according to a World Weather Attribution (WWA) analysis covered by Carbon Brief.
In both countries, the fires destroyed vast areas of native forests and grasslands, displacing thousands of people. In Chile, the fires resulted in 23 deaths.
Multiple drivers contributed to the spread of the fires, including extended periods of high temperatures, low rainfall and abundant dry vegetation.
The WWA analysis concluded that human-caused climate change made these weather conditions at least three times more likely.
According to the researchers, another contributing factor was the invasion of non-native trees in the regions where the fires occurred.
The risk of non-native forests
In Argentina, the wildfires began on 6 January and persisted until the first week of February. They hit the city of Puerto Patriada and the Los Alerces and Lago Puelo national parks, in the Chubut province, as well as nearby regions.
In these areas, more than 45,000 hectares of native forests – such as Patagonian alerce tree, myrtle, coigüe and ñire – along with scrubland and grasslands, were consumed by the flames, according to the WWA study.
In Chile, forest fires occurred from 17 to 19 January in the Biobío, Ñuble and Araucanía regions.
The fires destroyed more than 40,000 hectares of forest and more than 20,000 hectares of non-native forest plantations, including eucalyptus and Monterey pine.
Dr Javier Grosfeld, a researcher at Argentina’s National Scientific and Technical Research Council (CONICET) in northern Patagonia, told Carbon Brief that these species, introduced to Patagonia for production purposes in the late 20th century, grow quickly and are highly flammable.
Because of this, their presence played a role in helping the fires to spread more quickly and grow larger.
However, that is no reason to “demonise” them, he stressed.
Forest management
For Grosfeld, the problem in northern Patagonia, Argentina, is a significant deficit in the management of forests and forest plantations.
This management should include pruning branches from their base and controlling the spread of non-native species, he added.
A similar situation is happening in Chile, where management of pine and eucalyptus plantations is not regulated. This means there are no “firebreaks” – gaps in vegetation – in place to prevent fire spread, Dr Gabriela Azócar, a researcher at the University of Chile’s Centre for Climate and Resilience Research (CR2), told Carbon Brief.
She noted that, although Mapuche Indigenous communities in central-south Chile are knowledgeable about native species and manage their forests, their insight and participation are not recognised in the country’s fire management and prevention policies.
Grosfeld stated:
“We are seeing the transformation of the Patagonian landscape from forest to scrubland in recent years. There is a lack of preventive forestry measures, as well as prevention and evacuation plans.”
