Key developments
Latin America news roundup
TREE FELLING FALLS: Political shifts in Brazil and Colombia have “had a significant impact on tree felling”, with large reductions in deforestation occurring in both countries over 2023, according to analysis from the University of Maryland and the World Resources Institute that was covered by BBC News. Tree loss in the Brazilian Amazon decreased by 39%, although in the Cerrado – an important savannah in Brazil – it increased by 6%. In Colombia, primary forest loss decreased by nearly 50%, compared to last year. But, the outlet added, “increased tree felling and fires in Bolivia, Laos and Nicaragua wiped out many of these gains”.
WHERE THERE’S SMOKE: According to satellite data released last week, Venezuela “is battling a record number of wildfires”, fuelled in part by intense drought in the region, Reuters reported. More than 30,000 “fire points” were recorded in the country during the first three months of the year. The newswire wrote: “Man-made fires that are often set to clear land for agriculture are spreading out of control thanks to high temperatures and low rainfall in northern South America, as well as a lack of prevention planning, researchers say.” A University of Oxford fire researcher said that the fires “could be a worrying sign for what’s ahead” when Brazil enters its dry season.
COMMISSION CHANGE: The scientific community must “speak out strongly” against proposed changes to Mexico’s National Commission for the Knowledge and Use of Biodiversity (CONABIO), two academics wrote in an editorial in the journal Science. They explained that the government intends to “reduce CONABIO from a multi-ministry federal government agency to a branch within the environment ministry” and argued that this change would “strip CONABIO of its independent voice, credibility and influence on national and international policy”. The government is expected to make a final decision by the end of this month.
DENGUE ‘SURGE’: The Pan American Health Organization (PAHO) warned of a “surge in dengue cases in the Americas”, with more than 3.5m cases recorded to date – “three times more cases than those reported for the same period in 2023”, which was itself a record year, PAHO director Jarbas Barbosa said. According to PAHO: “Several environmental and social factors contribute to the spread of dengue, including rising temperatures, extreme weather events and the El Niño phenomenon.” Urbanisation and population growth also play a role, the organisation added.
Africa drought ‘disaster’
NATIONAL EMERGENCIES: More than 24 million people in southern Africa face hunger, malnutrition and water scarcity due to the combined impact of drought and floods, according to a warning from the charity Oxfam, CNN reported. It comes after Zimbabwe joined Zambia and Malawi in declaring a state of disaster over the drought, according to Sky News. Zimbabwe president Emmerson Mnangagwa made the emergency declaration in a speech on 3 April, where he called for $2bn (£1.6bn) in humanitarian aid, the broadcaster said. The Associated Press (AP) spoke to a mother affected by the drought in Zimbabwe.
CLIMATE ROLE: The “erratic” weather in southern Africa, which has lurched between drought and floods in recent months, is likely “spurred” by human-caused climate change, which is making extreme events more unpredictable, the AP said. It added that conditions have been worsened by El Niño, the naturally occurring climate phenomenon that periodically affects much of the globe. In southern Africa, El Niño “means below-average rainfall” and “sometimes drought”, the newswire reported.
EXTREME CONTINENT: Many other parts of the continent continued to face severe – and, in many cases, record-breaking – extreme weather. Much of northern Africa continued to face extreme heat, with the Moroccan city of Oujda recording a “minimum temperature” for April that was 7C higher than the previous record, according to a Twitter account tracking extreme temperatures. That temperature was close to the all-time record, logged in the month of July. (“Minimum temperature” refers to the coolest temperature in a 24-hour period, with high minimum temperatures indicating dangerously hot nights.) West Africa also continued to face record heat. Carbon Brief reported on how Africa’s most populous nation, Nigeria, was coping with the extreme temperatures.
Spotlight
The ‘grave threat’ of ghost roads
In this spotlight, Carbon Brief reports on a new study detailing the impact of “ghost roads” on deforestation rates in the Asia Pacific region.
“Ghost roads” – illegal or informal roads that do not appear on any map – are fast expanding in biodiversity-rich tropical nations.
Carved out by farmers, miners, loggers, land grabbers and drug traffickers, these illicit roads give more direct access to pristine tropical forests – and help extractors carry out their activities while evading detection by authorities or NGOs.
The absence of ghost roads from official records or international datasets makes understanding the scale of their impact on tropical forests extremely difficult.
A new study published in Nature this week aimed to reverse this.
“I think we all knew that ghost roads were a serious problem, but they hadn’t been studied in a concerted way,” study author Prof Bill Laurance, a conservation biologist at James Cook University in Cairns, Australia, told Carbon Brief.
Volunteer army
The research team focused on three tropical islands in the Asia Pacific: Borneo, Sumatra and New Guinea.
To try to understand the extent of ghost roads on the islands, the researchers deployed an army of more than 200 trained volunteers.
These volunteers walked over 1.42m plots, each one square kilometre in area, noting down the existence of roads that were missing from leading global datasets.
Study lead author Jayden Engert, a conservation ecologist and PhD student at James Cook University, told Carbon Brief that a broad range of people volunteered to help out with the mapping effort:
“We found volunteers through many different avenues, chiefly by advertising within our university and at other universities. We also ran a volunteer Map-athon with the Facebook group ‘Wild Green Memes for Ecological Fiends’, which brought in a decent amount of volunteers and also helped to raise awareness of the issue.”
Ghosts detected
The mapping effort revealed 1.37m km of ghost roads – 3-6.6 times more roads than were present in leading road datasets.
“I was blown away by how many unmapped roads there were,” Engert told Carbon Brief.
To understand how the ghost roads could be affecting deforestation rates, the scientists developed a map of their study area and quantified the percentage of forest loss in each plot.
They then used modelling to determine how the forest loss correlated with 38 biological and socioeconomic factors related to tree cover, including population density, distance to the nearest city and protected-land status – as well as ghost-road density and distance from ghost roads.
The research found that ghost-road density had by far the strongest link with forest loss out of all of the 38 factors studied.
Furthermore, ghost-road building “almost always preceded local forest loss”, the researchers wrote in their study.
They also found that the relationship between road density and forest was nonlinear, “with deforestation peaking soon after roads penetrate a landscape and then declining as roads multiply and remaining accessible forests largely disappear”.
They concluded by saying:
“Collectively, our findings suggest that burgeoning, poorly studied ghost roads are among the gravest of all direct threats to tropical forests.”
Laurance told Carbon Brief that their findings are likely to apply to other parts of the tropics:
“There’s absolutely no doubt in my mind that other developing tropical nations are facing similar challenges with ghost roads. We also have been working in the Amazon and central Africa for the past several decades, and there we see many similar and equally daunting realities on the ground.”
News and views
FARM FLU: The US Department of Agriculture has confirmed cases of the “highly pathogenic” avian influenza in dairy cows in Idaho, bringing the number of confirmed outbreaks to 12 herds across five states, with other tests ongoing in presumptive positive cases. The country’s largest fresh egg producer also reported an outbreak, leading to “rising concern” despite assurances that the “risk to the public remains low”, the Associated Press reported. The detection of the virus in cattle raises “critical questions about whether the country is equipped to handle an influenza outbreak after the coronavirus pandemic…exposed the weaknesses in the nation’s public health infrastructure and decimated the public’s trust in key federal agencies”, the Washington Post reported.
INDIGENOUS INDONESIANS: Indonesian president-elect Prabowo Subianto must prioritise ratifying the country’s Indigenous Peoples bill, two Indigenous-rights activists argued in China Dialogue. The bill was first proposed in 2009, but president Joko Widodo failed to ratify it despite “repeated promises to do so”, the writers noted, adding: “Prabowo’s new government appears set to continue expanding Indonesia’s domestic resource-processing capabilities…signal[ling] the continued, unjust plunder of Indigenous territory.” Indonesia is home to around 22 million Indigenous people and more than 2,500 Indigenous communities. They face “deforestation, agricultural crises, marginalisation and discrimination and the usurpation of customary rights”, as well as voter disenfranchisement, the activists said.
NEW BIODIVERSITY CHIEF: BusinessGreen reported that German diplomat and environmental-policy expert Astrid Schomaker has been appointed the next executive secretary of the Convention on Biological Diversity (CBD), the UN body that oversees negotiations on biodiversity loss. According to the publication, Schomaker has spent the last seven years overseeing environmental diplomacy and global sustainable development at the European Commission. She replaces the acting executive secretary, British CBD veteran Dr David Cooper. Carbon Brief published an in-depth interview with the last permanent executive secretary, Tanzanian lawyer and diplomat Elizabeth Maruma Mrema, in 2022.
WHALE OF A TIME: Māori king Tuheitia Pōtatau Te Wherowhero VII and other Indigenous leaders in the Pacific have “urged the legal recognition of whales as persons with inherent rights”, according to the Pacific Islands News Association. The leaders are endorsing the He Whakaputanga Moana, or the Declaration for the Ocean, which “outlines a comprehensive plan” for protecting whales from “unsustainable practices, pollution and climate change”, the outlet explained. It will do so through establishing protected areas and integrating Indigenous knowledge with other science. Travel Tou Ariki, a high chief from the Cook Islands, said: “Whales play a vital role in the health of our entire ocean ecosystem…We must act with urgency to protect these magnificent creatures before it’s too late.”
BIG MEAT COP: Lobbyists from the world’s largest meat companies have celebrated a “positive outcome” from the last global climate summit, COP28, according to a DeSmog investigation. Speaking on a virtual panel organised by the trade outlet FeedStuffs, three representatives for US livestock firms said they were left “excited” and “enthusiastic” for their industry’s prospects after the summit, which saw countries commit to a series of voluntary pledges for tackling agricultural emissions without addressing meat consumption. Constance Cullman, the president of the US lobby group the Animal Feed Industry Association (AFIA) said COP28 left her organisation with “a far more positive outcome than we had anticipated”, according to DeSmog.
STANDING TOGETHER: Advocacy groups in Brazil, the Democratic Republic of the Congo, Guatemala, Kenya, Liberia and Mexico have launched a new initiative to protect environmental defenders, Liberia’s Daily Observer reported. The initiative will provide “partnerships, financial support and training” for civil-society organisations to protect them against the risks that environmental defenders face, such as threats, violence and smear campaigns, the newspaper said. Three environmental defenders were recently killed during protests in Kinjor, Liberia.

New science
Threat of mining to African great apes
Science Advances
Up to one-third of Africa’s great apes face risks from mining projects, new research found. The study looked at the overlap between industrial mining projects and great ape distribution in 15 African countries, excluding the Democratic Republic of the Congo due to a lack of available data. The research found that industrial mining projects overlap with the habitat of nearly 180,000 apes. It also found that the overlap was largest in west African nations, including Senegal and Sierra Leone. In the paper, the authors noted that the “rapid growth of clean energy technologies is driving a rising demand for critical minerals”, which are increasingly being mined in Africa.
The asymmetric impacts of international agricultural trade on water use scarcity, inequality and inequity
Nature Water
A new study found that the water “embedded” in agricultural trading “disproportionately benefits the rich and widens both the water scarcity and inequity gap between the poor and the rich”. Researchers used a global model of crop water requirements to simulate the amount of water used for irrigation for 26 different crops, then analysed how international trade affects water scarcity and inequity in eight countries. They found that the poorest people in developing countries “suffer[ed] from both increased water scarcity and inequity”, but poor populations in developed countries were more likely to benefit. They also identified the trade of staple crops as “the major driving factor” affecting these in most countries, due to the large volumes of staple crops traded.
Significant shifts in latitudinal optima of North American birds
Proceedings of the National Academy of Sciences
The optimal location for North American birds has shifted northward by an average rate of 1.5km each year in response to climate change, a new study found, representing a total distance moved of 82.5km over the past 55 years. The research uses modelling to estimate the “latitudinal optima” of 209 American bird species, drawing on bird population abundance data over the past half-century. It found that one-third of the species studied showed a “significant shift of their optimum” over the study period, with birds in western North America experiencing the biggest shifts. The results “directly implicate climate-induced increases in temperature as the primary driver” of bird abundance shifts, the researchers said.

Cropped 10 April 2024: ‘Ghost roads’ deforestation; Record wildfires; Southern Africa drought
This summer has seen Europe suffer through a series of record-breaking heatwaves.
Amid widespread media coverage of the number of deaths and the influence of climate change, the UK’s Daily Telegraph reported on new research with the incorrect headline: “Heatwaves caused by fall in pollution.”
The article was shared on social media by Richard Tice – deputy leader of the hard-right, climate-sceptic Reform UK party – along with a number of prominent rightwing commentators.
Tice claimed that “net stupid zero is contributing to rising temperatures, not helping”, adding that “we have been gaslit and lied to”.
GB News followed up with its own article, incorrectly headlined: “Britain’s scorching heatwaves caused by falling pollution levels, researchers find.”
Scientists tell Carbon Brief that the framing of heatwaves being “caused” by declining air pollution is “wrong”.
While a drop in pollution has reduced the cooling impact it has had in the past, the scientists say, Europe’s summer heatwaves are primarily becoming more extreme “as a result of greenhouse-gas-induced warming”.
Another scientist adds that “any attempt” to link this research to net-zero policies is “simply wrong”.
Fast warming
The extensive reporting around Europe’s heatwaves in recent months has often mentioned that Europe is the world’s fastest-warming continent.
The new study in question aims to unpack why Europe’s summer temperatures are rising more quickly than other regions of the northern hemisphere’s mid and high latitudes.
The research – published in Geophysical Research Letters – explores the role of air pollution and, specifically, how it affects circulation patterns in the atmosphere.
(The study focuses on long-term trends in European summers and does not include the very recent heatwaves.)
Human-caused emissions of aerosols – tiny, light‑scattering particles produced mainly by burning fossil fuels – have long acted to “mask” global warming. This is largely because they absorb or reflect incoming sunlight and influence the formation and brightness of clouds.
To understand how the climate of Europe – or any region – is changing, scientists need to take into account a whole range of factors, says Prof Bjørn Samset, a research professor at Norway’s Center for International Climate Research (CICERO), who was not involved in the work.
This includes “greenhouse gases, aerosols, land-use change, natural variability and how they all interact”, he says, adding:
“The effects of air pollution on circulation, which is the topic here, has long been difficult to pin down.”
As European countries improved their air quality through the second half of the 20th century, the cooling effect of aerosols has gradually been removed.
This can boost heatwaves in two ways – directly, by letting more sunlight reach the land surface and, indirectly, by influencing the jet stream.
Using hundreds of simulations from nine climate models, the new study finds that a decline in aerosols is resulting in more frequent “quasi-stationary Rossby waves”.
Rossby waves are huge meanders in the jet stream. Occasionally, they become slow-moving – or “quasi-stationary” – which allows weather systems to get stuck over one region, leading to prolonged heatwaves.
These circulation changes have contributed to Europe’s rapidly warming summers.
However, while Europe’s heatwaves are being influenced by declining aerosols, it is “wrong” to say they are being “caused” by them, says Prof Erich Fischer, a climate scientist at ETH Zurich.
Fischer, who was not involved in the study, tells Carbon Brief:
“Heatwaves are caused by high-pressure systems and are now much more frequent and intense because they are happening in a climate that is much warmer than 100 years ago as a result of greenhouse-gas-induced warming.
“The paper shows that the greenhouse-gas-induced summer warming had been temporarily masked by air-polluting aerosols. The full extent for European summers only becomes visible now as the air-polluting aerosols have declined.”
Samset adds:
“Air pollution never causes or removes global warming, it only temporarily moderates it.”
Study lead author Dr Pedro Roldán‐Gómez, an associate researcher at the Barcelona Supercomputer Centre, is quoted in the Daily Telegraph saying that “most” of the “excess warming” in Europe, beyond that of comparable regions in the northern hemisphere, can be linked to declining aerosols.
But, earlier in the article, the newspaper interprets this as, simply, “most of the extra heat experienced in Britain and Europe” is down to air pollution.
GB News uses a similar phrasing, reporting that “much of the additional warming across Britain and western Europe since the 1980s is linked to the sharp decline in airborne particles known as aerosols”.
This is “misleading”, says Fischer, while Roldan-Gomez tells Carbon Brief that this is a “tricky point”, which “could lead to wrong interpretations if not properly explained”. He adds:
“The contribution of greenhouse gases is, in any case, the most important factor.”
Cleaner air
The Daily Telegraph’s article was seized upon by Reform’s Richard Tice to claim that “cleaner air” was causing higher temperatures, rather than CO2.
This continued his position – refuted by long-established climate science – that CO2 does not drive global warming.
Tice also claimed in his post that net-zero policies are “contributing to rising temperatures”. Tice appears to be linking declining air pollution to a shift from fossil fuels to renewable energy.
Samset points out that net-zero became a goal “decades later” than the cumulative efforts to reduce air pollution since the 1980s and that it is “simply wrong” to link it to the study.
“The scientific community will keep working to understand how greenhouse gas warming and air pollution interact,” he says, but “nothing we do will change the fact that the consequences of global warming are due to human-induced CO2 emissions”.
Fischer adds:
“Let us not forget that cleaning up air-polluting aerosols is highly desirable. According to the World Health Organisation, 7 million people still die prematurely every year due to air pollution.”
Clean air legislation
Finally, the Daily Telegraph article and the study itself both attribute Europe’s declining air pollution from the 1980s onwards to the Montreal Protocol.
This is a “glaring error”, Samset says, and it is “surprising that it wasn’t picked up” in the peer-review process for the study. He explains:
“The Montreal Protocol did not deal with air pollution. It dealt with ozone-depleting gases and has been an extremely successful multi-national effort against environmental damage. “
Clean air legislation was already in place in many European countries by the time the Montreal Protocol was signed in 1987, says Samset.
In response, Roldán‐Gómez says that while the protocol did not target aerosols specifically, it “boosted the clean air policies”.

Empowering women through greater access to finance could “strengthen” households’ resilience to “climate shocks”, according to a new study.
Published in Climate Risk Management, it analyses the impact of financial access on “women-headed households” in sub-Saharan Africa.
The study finds that where women had formal financial access – such as through owning a bank account – households were more able to withstand short-term shocks.
It adds that “climate shocks”, such as extreme weather events and the impacts of climate change, can cause economic crises, which destabilise communities and households.
However, the authors say that in order to protect households from long-term climate vulnerabilities – including “droughts, floods and sea-level rise” – financial access would need to be paired with wider efforts to tackle gender inequality.
They add that the findings could have important implications for policy in sub-Saharan Africa, where many countries and households are vulnerable to climate disasters.
Financial inclusion
The study highlights that entrenched gender disparities mean many women still have unequal access to financial services in sub-Saharan Africa
For example, women are still less likely to have their own bank accounts and instead are often dependent on male relatives for access to finance.
The number of women with access to an account in the region had risen to 52% as of 2024, according to data from World Bank Group.
However, as shown in the chart below, the gap between men and women has also increased, rising from just under 5 percentage points in 2011 to 12 in 2024.
Using survey data from Afrobarometer, the new study analyses 25,511 women-headed households across 37 sub-Saharan countries.
The authors use the Organisation for Economic Co-operation and Development’s (OECD) framework to measure “financial inclusion”. This looks at factors such as having a bank account, owning a mobile phone and having internet access.
Francis Anaisie, a co-author on the study, tells Carbon Brief the researchers were motivated by the UN’s sustainable development goals (SDGs). Anaisie, an economist at the University of Cape Coast, Ghana, says the study specifically looked at SDGs five and 13, on gender equality and addressing climate issues. He adds:
“Financial inclusion is one of the key policy tools for empowering women or for empowerment. But as to whether this actually translates into better climate outcomes for women is not known or is limited; this study seeks to address that gap.”
The study finds households with higher levels of financial access for women had higher levels of women’s empowerment, when this is defined as the ability to make choices and have control over economic and social outcomes.
This was checked by cross-comparing financial access against different measures of women’s empowerment, such as financial security, voting rights and connection to communities.
In particular, the study found that “financially included” women had greater political and economic empowerment, such as financial security and voting rights. On some measures of social empowerment, however, the link was weaker – financial access alone was not enough to erase cultural and social barriers to gender equality.
Women and climate change
It has been well documented that women are more vulnerable to the impacts of climate change than men.
Environmental shocks affect women disproportionately due to a range of factors. These include income disparities, higher rates of displacement and unequal access to land.
Financial inequality and barriers to economic resources, such as needing internet access to make digital payments, play a key role in climate vulnerability, says Tracy Kajumba. She is director for the Least Developed Countries initiative for Effective Adaptation and Resilience (LIFE-AR) interim secretariat at the International Institute for Environment and Development (IIED).
Kajumba, who was not involved in the study, explains to Carbon Brief:
“Women are on the front line doing farming, planting, harvesting and these things that are all impacted [by climate change]. If they don’t have the income to invest either in drought-resistant crops or water-saving technologies, it becomes difficult for households to adapt.”
Calculating climate resilience
The new study measures the impact of financial inclusion on women’s empowerment and, in turn, on climate resilience.
It evaluates a household’s ability to withstand and recover from “shocks and stressors” by using a UN Food and Agriculture Organization metric for “resilience index measurement and analysis” (RIMA).
For example, questionnaires are used to gather information about households in certain areas. The data is then used, together with key indicators, to quantify a household’s resilience to food insecurity, climate variability and economic crisis, amongst other risks.
The 25,511 households surveyed across sub-Saharan Africa were found to be relatively resilient overall and had a high capacity to bounce back from climate shocks. However, they had much lower ability to adapt, in order to build protective capacity in advance of extreme events.
In addition, the study finds that women’s financial empowerment had a positive impact on a household’s ability to “absorb” a climate shock, suggesting that financial access is critical for responding to climate change.
Increased empowerment through financial access enables women to make decisions about planting crops, to access credit in emergencies and to buy or sell food at a better price, the study notes.
For example, it says increased financial access and women’s empowerment help households to deal with the immediate consequences of an extreme weather event, such as a drought. This could be through building community mutual-support networks and by enabling access to savings, to keep the household running.
Anaisie says the study shows women’s empowerment has a significant impact on climate resilience. He tells Carbon Brief:
“If we include women in the financial system, in the case of any climate issue they can save, they can be independent, they can rely on investment to absorb these shocks. This empowerment will help them to be more resilient to climate shocks…We can make progress because SDG goals are all about inclusiveness. It’s all about inclusive growth.”
However, the study notes that financial access does not necessarily create long-term change, which would make the household less vulnerable to extreme weather in the first place.
The authors suggest that lasting structural and cultural change is important for bringing about long-term resilience. They say that policies to address gender inequalities would help bring this about.
They say such policies could include gender-sensitive agricultural credit schemes, subsidised climate insurance for women farmers in drought-prone regions, joint land-titling programmes and quotas for women in local climate-adaptation committees.
Such policies would have helped women impacted by recent severe floods in Ghana to protect their savings, Anaisie explains. He tells Carbon Brief:
“Women are engaged in economic activities, especially informal activities. They have resources and money, but when the flood came in, many women lost that. If they had access to insurance, this flood wouldn’t have cost them that much.
“So, if the government comes out with financial initiatives, training, civic education and gender-focused initiatives, leadership training, women will be empowered and this will translate into their resilience with regards to climate change.”
Addressing climate vulnerability in sub-Saharan Africa
The study could have policy implications for sub-Saharan Africa, a region particularly vulnerable to the effects of climate change. The region faces increasingly extreme weather, heatwaves, droughts, wildfires and floods, as well as food scarcity and threats to crops.
The study suggests that policies to address structural and cultural barriers to women’s financial autonomy could be a key way to build climate resilience across the region.
However, it recognises that even where financial access is expanded, gender norms and cultural constraints continue to shape women’s social empowerment. This, in turn, affects their ability to adapt to climate change in the long term.
Ultimately, addressing structural inequalities is needed to minimise climate vulnerability, says Kajumba. She adds that supporting adaptation with financial access can allow households to absorb shocks without falling into poverty – and to rebuild after climate impacts.
Kajumba says that supporting adaptation with women’s financial access can allow households to absorb shocks without falling into poverty – and to rebuild after climate impacts. She adds:
“When they are supported [with] microloans, savings and all that, you will see change in income, change in households, change in health and education for the children as well.”
However, Kajumba notes that structural inequalities still “amplify” women’s vulnerability to climate impacts and make it harder for them to exercise agency and leadership. She adds:
“The tools that are being used are not always favourable for women…When we look at women in leadership and participation, you cannot lead or you cannot participate unless you have some level of income.”

Access to finance ‘strengthens climate resilience’ among sub-Saharan women
As 2026 passes its halfway point, the world is watching one of the most rapidly intensifying El Niño events in the modern record take shape in the tropical Pacific.
The developing El Niño is boosting expectations for global temperatures, both this year and next.
El Niño is the warm phase of a recurring climate pattern in the tropical Pacific that releases heat from the ocean into the atmosphere, temporarily raising global temperatures and reshaping rainfall and extreme weather around the world.
Carbon Brief’s “state of the climate” report in April gave 2026 a 19% chance of setting a new global temperature record.
That chance now stands at 35% – a near-doubling in four months – with virtually all of the change driven by ever-stronger El Niño forecasts.
The key findings from the first half of 2026 include:
- The first six months of 2026 were the third-warmest start to a year on record – around 1.4C above pre-industrial levels – behind only 2024 and 2025.
- While the first few months of the year came in as the fourth or fifth warmest, both May and June were the second-warmest ever recorded as El Niño conditions took hold.
- El Niño conditions arrived in April and reached the threshold for a “strong” event by June, when the Niño3.4 index reached 1.6C. Of the 667 model runs Carbon Brief examined, 91% project a peak later this year that is above the strongest El Niño in history.
- The chance that 2026 beats 2024 as the warmest year on record has risen to 35%. Carbon Brief’s central estimate remains that 2026 will be the second-warmest year, at around 1.51C above pre-industrial levels.
- Whether 2026 sets a record will depend on the dataset: the odds range from around two-in-three in NASA and Berkeley Earth data to around two-in-10 in ERA5 and one-in-10 in the JRA-3Q reanalyses.
- June 2026 was western Europe’s hottest June on record, amid a heatwave that set hundreds of individual records. Nearly 9% of the world’s surface saw record June warmth.
- The developing El Niño will have its largest impact on 2027, which Carbon Brief projects to be around 1.7C above pre-industrial levels – this would comfortably set a new record for the warmest year.
- Arctic sea ice has spent 39 days of 2026 so far at, or below, record daily lows following its joint-lowest winter maximum in the satellite era.
Third-warmest start to a year
Carbon Brief analyses records from six different groups that report global surface temperatures: NASA GISTEMP, NOAA GlobalTemp, Hadley/UEA HadCRUT5, Berkeley Earth, Copernicus/ECMWF ERA5 and the JMA JRA-3Q reanalysis.
The first half of 2026 was the third warmest on record in every one of the six datasets, behind only 2024 and 2025. The figure below shows annual temperatures since 1970, along with the 2026 year-to-date average (January-June) for each group.
January 2026 was only the fourth- or fifth-warmest January on record, as lingering weak La Niña conditions suppressed temperatures. Since then, each month has climbed the rankings.
La Niña is the cool phase of the El Niño-Southern Oscillation (ENSO). It typically brings wetter conditions to Australia, Indonesia and equatorial South America and drier conditions to the southern US.
March was second-to-fourth warmest across datasets, April the third and both May and June were the second warmest ever recorded, behind only the corresponding months of 2024.
The chart below shows how June 2026 (thick red line) came in around 0.08C below the June record set in 2024 in the average of the six datasets.
Meanwhile, Copernicus reported that global sea surface temperatures over the ice-free oceans set a new June record.
A record-breaking El Niño
ENSO is the largest source of year-to-year variability in global temperatures.
The most common way to assess the strength of an El Niño or La Niña event is by looking at the sea surface temperature anomaly in the “Niño3.4” region of the tropical Pacific.
El Niño and its sister La Niña occur when temperatures in the tropical Pacific are more than 0.5C (El Niño) or less than 0.5C (La Niña) below normal, where normal is defined by removing the effects of long-term climate change.
The thresholds for defining the strength of an El Niño or La Niña are above/below 1C for “moderate” events, 1.5C for “strong” events and 2C for “very strong” (or “super”) events.
After two years dominated by La Niña conditions, the tropical Pacific flipped decisively in April when the Niño3.4 index crossed the 0.5C El Niño threshold. It subsequently reached 1C in May and hit 1.6C in June, marking one of the fastest onsets in the observational record.
In the first few weeks of July, the index shot above 2C, significantly outpacing the speed at which any prior El Niño events developed.
Forecast models expect even more to come.
An analysis by Carbon Brief of the median of 667 model runs from 14 different modelling groups suggests that sea surface temperatures in theNiño3.4 region could peak at 3.59C between July and December.
More than 91% of runs predict the strongest El Niño event in the modern record. The previous record was set during the event of 2015-16, when temperatures peaked around 2.75C.
This is shown in the chart below, which features a histogram of the likelihood of different possible 2026 El Niño peaks across all the models on the top. The forest plot beneath shows the best estimate and range of outcomes predicted by each individual model.
The median forecast in every one of the 14 models suggests a peak that exceeds the 2C “super” El Niño threshold, with most models peaking in November or December.
Some caution here is warranted, however. Raw model Niño3.4 anomalies are measured against a fixed climatology. Because the entire tropical ocean has warmed due to human-caused greenhouse gas emissions, the models tend to overstate event strength relative to the historical record.
A cleaner comparison uses the relative Niño3.4 index (RONI), which subtracts the average tropical ocean warming.
This relative measure suggests the median forecast peak for El Niño in the latter half of 2026 is 3.1C. The prior record stands at a lower 2.69C, set in 1982-83.
Nevertheless, 77% of model runs still show a new record event occurring. This is shown in the chart below.
In summary, on both indexes, the central expectation is now for the strongest El Niño in the observational record.
Model forecasts made in the spring and early summer have historically shown some bias toward overpredicting event strength. However, forecasts made after the spring are considerably more reliable.
Widespread record warmth and a massive European heatwave
The map below shows the temperature anomaly for the first half of 2026 in the ERA5 dataset, relative to a 1981-2010 baseline period.
It shows how the largest warm anomalies were found across the Arctic – particularly north of Scandinavia and Svalbard – as well as western Europe, the western US, northern Mexico, central Asia, western China, eastern Russia and the Antarctic Peninsula region.
The developing El Niño is clearly visible as a tongue of warm anomalies stretching along the equatorial eastern Pacific. Only a few regions – central Canada, Alaska and parts of the Southern Ocean – saw temperatures below the 1981-2010 average.
Where 2026 ranks against history is even more striking. The map below shows where the period of January-June 2026 ranked among all 87 years in the ERA5 record, which stretches from 1940 to 2026. Grid cells marked in red saw temperatures in the first half of the year that were in the top-five warmest years.
More than 30% of the global surface had a top-five warmest start to the year and 7.1% saw its warmest on record, including much of western Europe, the eastern equatorial Pacific and the seas around Japan.
Not a single grid cell had a top-five coolest start to the year. In June alone, 8.9% of the world’s surface saw record warmth for the month. This is illustrated in the map below, where grid cells marked in red saw temperatures that were in the top-five warmest years and grid cells in blue in the top-five coolest.
The standout regional temperature event was a heatwave that struck Europe in late June.
Western Europe had its hottest June on record, recording an average temperature of 3.05C above the 1991-2020 average and beating the record set only a year earlier, according to Copernicus. A heat dome over 22-30 June broke 10 all-time national heat records and around 400 long-record station records.
France set a new June national record of 44.3C, while the UK broke its June record on three consecutive days, reaching 37.3C. The humid heat drove a death toll estimated in the thousands.
A separate heat dome also brought record June temperatures to parts of North America in late June.
On track to be second warmest, but a real chance at first
Carbon Brief’s updated projection for 2026 as a whole combines the observed January-June temperatures with the latest El Niño forecast. It uses a statistical model trained on the historical relationship between the first half of the year, ENSO conditions and annual temperatures observed over 1950-2025, excluding major volcanic eruption years.
Carbon Brief estimates that 2026 will be around 1.51C above pre-industrial levels, with a 90% range of 1.45C to 1.57C, shown by the yellow dot in the chart below.
This is up from 1.47C in the projection set out in April – and is notably more certain now that half the year has passed.
This central estimate would make 2026 the second-warmest year on record, just below 2024 (1.52C) and ahead of 2023 (1.43C) and 2025 (1.41C).
Carbon Brief’s modelling puts the chance that 2026 beats 2024 as the warmest year on record at 35%, using the average of the six different surface temperature records assessed. It puts the chance that 2026 comes in above 1.5C at around 63%.
If it does, 2026 would be the second calendar year – after 2024 – where warming averaged above 1.5C, in a further sign that the world is rapidly approaching the Paris Agreement’s 1.5C limit.
A single year above 1.5C does not by itself constitute a breach of the goal, which refers to the longer term average temperature of the planet. This is defined as the midpoint of a 20-year period by the Intergovernmental Panel on Climate Change (IPCC).
These likelihood of a record have been climbing rapidly throughout 2026.
Global temperatures so far throughout the year have run well below the record-setting levels of 2024 – around 0.13C cooler over the first six months.
On their own, temperatures observed so far in 2026 would make a new annual record unlikely.
However, rerunning the projection using only the data available at the end of each month since March – including both the year-to-date observations and the El Niño forecast issued that month – shows a shifting picture.
Using March data, 2026 had just a 7% chance of setting a new record. That rose to 16% in April, 24% in May, 27% in June and 35% using the latest data in mid-July.
This is shown in the chart below.
Notably, this rise has little to do with observed temperatures. The year-to-date anomaly has actually drifted slightly down, from 1.41C after March to 1.39C after June.
Observed temperatures and fewer remaining months of the year contributed only around four percentage points of the 28-point rise in the likelihood; the remaining ~84% of the change comes from successive upward revisions to the El Niño forecast for late 2026.
However, whether 2026 ends up becoming the warmest year on record may end up depending on which dataset is used.
Running the same projection gives odds of a 2026 record of around two-in-three for Berkeley Earth (66%) and NASA GISTEMP (65%), but only 35% for HadCRUT5, 24% for NOAA and just 13% and 9% for the ERA5 and JRA-3Q reanalyses, respectively.
This is shown below.
The divergence between projections mostly reflects how exceptional each dataset’s 2024 was.
The reanalysis approaches recorded a particularly warm 2024, leaving 2026 more ground to make up. GISTEMP and Berkeley, on the other hand, project 2026 modestly above their 2024 values.
A repeat of the situation in 2015 where different groups disagreed on record rankings is a real possibility. Headlines in January 2027 may hinge on choices of dataset.
2027 likely to be the warmest year in human history
The biggest climate story of the developing super El Niño may not be 2026 at all.
Global temperatures typically lag in the tropical Pacific by around three months. So, an El Niño event peaking in November and December 2026 will have its largest warming influence on 2027.
We saw this same pattern occur in 1997-98, 2015-16 and 2023-24 – where the year in which the El Niño developed was warm, but the following year was record-smashing.
Carbon Brief has extended its projection into 2027 by using the historical relationship between year-over-year temperature changes and ENSO conditions in the preceding autumn.
This yields a best estimate for 2027 of around 1.71C above pre-industrial levels, with a 90% range of 1.49C to 1.93C. This is shown by a yellow square on the chart below.
That would give 2027 a 92% chance of setting a new global temperature record and a 94% chance of exceeding 1.5C.
Taking 2026 and 2027 together, there is a 93% chance that at least one of the two years sets a new record.
The 2027 estimate is more uncertain than the 2026 one. As with 2026, there are uncertainties in the projection due to unknowns around exactly how strong the El Niño peak proves to be and how quickly it decays.
However, even the low end of the 2027 range would put it among the warmest years on record and the central estimate of 1.71C would exceed 2024 by nearly 0.2C.
If these projections bear out, the 2020s will have delivered new global temperature records in 2023, 2024 and 2027 – and potentially 2026 too – with a number of individual years well above the 1.5C threshold.
The long-term warming trend, driven by human emissions of carbon dioxide and other greenhouse gases, has increased from around 0.18C per decade in the early 2000s to around 0.27C per decade today. El Niño and La Niña play a big role in determining which years along that rising path stand out as records.
Arctic sea ice at record lows
Arctic sea ice has spent much of 2026 in record-low territory.
Following the joint-lowest winter maximum in the satellite record in mid-March, daily extent has set or tied record lows for the date on 39 days so far this year, including extended spells in mid-to-late March and in early-to-mid June.
The most recent record-low days were in early July.
The chart below shows how Arctic sea ice in 2026 (dark red line) has been below the historical range (shaded red).
It also shows how Antarctic sea ice (dark blue), meanwhile, has remained below the 1979-2010 range for almost all of 2026 to date.
As of mid-July, Arctic extent is a bit below the 1979-2010 historical range for the date, though it remains around 0.6m square kilometres (km2) larger than the record low for the date set during 2020’s exceptional summer melt season.
The trajectory over the coming two months will determine whether 2026 challenges 2012’s record September minimum. Early-summer conditions are a poor predictor of the September minimum, which depends heavily on summer weather.
Antarctic sea ice, meanwhile, is currently around 300,000km2 below the historical envelope, but has stayed well clear of the record lows set in 2023 and has not set any new daily records yet this year.
