Loss of labour caused by heat stress wiped out the equivalent of 4% of Africa’s GDP in 2022, warns a new report from the Lancet Countdown on Health and Climate Change.
The eighth iteration of the annual report features 47 different indicators of climate change and human health, such as heat mortality, food insecurity and air pollution exposure. For the first time, the report includes a dedicated section on regional trends, highlighting the inequalities between developed and less developed regions.
On extreme heat, for example, it finds that in small island developing states, 103 days of health-threatening temperatures every year are attributable to climate change over 2018-22. Across Europe, North America and Oceania, this number is less than 30.
This is also the first Lancet Countdown report to include projections on how the indicators might worsen in a warmer world. Under a 2C warming scenario, for example, 525 million additional people will experience food insecurity by 2041-60, compared with the 1995-2014 baseline.
Many indicators suggest that the world is “accelerating in the wrong direction”, the report warns. It finds that the strategies of the world’s 20 largest oil and gas companies would result in emissions surpassing levels consistent with limiting warming to 1.5C by 173% in 2040.
However, the lead author of the report told a press briefing there is also reason for “hope”. The number of people who died due to fine particulate air pollution decreased from 1.4 million in 2005 to 1.2 million in 2020, for example. And scientific research and media engagement with health and climate change have both continued to grow, the report says.
Heat stress
In a “major addition”, the report presents attribution analyses of key indicators, to quantify the influence of climate change on them for the first time.
Over 2018-22, the average person experienced 86 days of “health-threatening high temperatures” per year, according to the report. Around 60% of these temperatures were made more than twice as likely due to climate change, it says.
Heat-related deaths often follow exposure to extreme heat – and people under the age of one or over the age of 65 are particularly vulnerable to high temperatures.
Globally, heat-related deaths in people aged over 65 were 85% higher in 2013-22 than in 1991-2000, the report finds. This rise is “substantially higher” than the 38% increase expected if the climate had remained constant and only demographics had changed, it adds.
For the first time, the report also includes projections of what key indicators may show in the future. The report authors developed these with the help of the Climate Vulnerable Forum – a group of countries highly vulnerable to the impacts of climate change.
They find that if global temperature rise is only limited to 2C above pre-industrial temperatures, stabilising at 1.8C by the end of the century, then annual heatwave exposure for people older than 65 will rise by more than 2,500% by 2080-2100, compared to 1995-2014 levels.
The report warns that outdoor workers are the “most exposed to climate hazards”. It estimates that in 2022, around 1.6bn paid workers – mainly “young or middle-aged” men – worked outside. However, the report notes that unpaid labour, which is often disproportionately carried out by women, is not included in these figures.
The graphs below show the average annual hours per person over 1991-2022 when “light physical activity” entailed at least a moderate (light orange), high (dark orange), or extreme (red) heat stress risk.
From left to right, countries are grouped according to their human development index – a measure of a country’s development, where higher numbers indicate greater development. Least developed countries (low HDI) are shown in the left-most chart and the most developed countries (very high HDI) are in the right-most chart.

Heat exposure caused 490bn potential labour hours to be lost globally in 2022, amounting to 143 hours per person, the report estimates. This is nearly a 42% increase from the 1991-2000 average, it adds.
The authors find that loss of labour due to heat exposure resulted in a $863bn loss of “potential income” in 2022. The agriculture sector was hit the hardest by the loss of labour, accounting for 82% of losses in low HDI countries, they add.
Dr Marina Romanello is the executive director of the Lancet Countdown, a climate change and health researcher at University College London and lead author on the report. She told a press briefing that workers in the agricultural sector are “heavily exposed to the elements” and often have few resources to protect themselves.
She added that in countries with a low HDI, agricultural workers are often in charge of local food production, meaning that heat-related labour loss has direct implications for food security.
Loss of labour due to heat stress wiped out the equivalent of 4.1% of Africa’s GDP in 2022, mainly from losses in the agricultural sector, the report finds. Meanwhile, Europe and North America only saw labour losses equivalent to 0.1% and 0.2% of their GDP, respectively.
The graph below shows effective income losses in 2022 due to heat stress in agriculture (blue) and other sectors (red), as a percentage of GDP, by continent.

Unequal impacts
The authors also explore how the changing climate affects people indirectly, including through changes in agriculture and the spread of disease.
The report finds that the global land area affected by at least one month of “extreme drought” per year increased from 18% in 1951-60 to 47% in 2013-22. The map below shows the change in the number of months of extreme drought between these two time periods, where red indicates an increase in drought and blue a decrease.

Africa was also the region most affected by droughts over 2013-22, with 64% of its land area affected by at least one month of extreme drought per year – up from 9% in 1951-60 – the report finds.
Year-round drought affected many “vulnerable areas” in 2022, the report warns. It highlights the ongoing drought in the Horn of Africa, where millions of people have been pushed into famine. (Separate analysis has found that the drought “would not have happened” without climate change.)
The Lancet adds that the higher frequency of droughts and heatwaves in 2021 pushed 127 million more people into “moderate or severe” food insecurity, compared to 1980-2010. This was one of the most “shocking” findings of the report, Romanello told the press briefing.
The report projects that under a 2C warming scenario, 525 million more people will face food insecurity by 2041-60 than in the 1995-2014 baseline.
Climate change is also increasing the range of certain pathogens. Warmer seas have already increased the area of coastline suitable for Vibrio bacteria – a pathogen that can cause sickness in people and animals.
Meanwhile, a combination of climate change, urbanisation and human movement are driving up cases of dengue fever, the report finds. It says that “cases of dengue have doubled every decade since 1990, and almost half of the world population is now at risk of this life-threatening disease”.
However, the report also points to positive developments, such as the increase in research on climate change and health.
The number of scientific papers investigating the links between health and climate change in 2022 was three times higher than in 2012, the report finds. It adds that most research focuses on Asia and studies the impacts of climate change on health, although there is a rising number of papers addressing mitigation and adaptation too.
‘Unjust transition’
The report also assesses the progress of the global energy transition, stating that the world is “often moving in the wrong direction”.
Developed countries still have much higher per-capita emissions than less developed ones. In 2020, per-person CO2 emissions in Oceania, for example, were 14 times higher than in Africa and more than three times higher than in Asia, according to the report.
The authors paint a picture of uneven progress in the push to decarbonise. Developed nations are making “steady but insufficient progress towards transitioning”, while less developed nations are not receiving the funding they need to do the same.
“Modern renewables” such as wind and solar accounted for 90% of new electricity capacity in 2022, the report finds. However, it notes that only 1% of renewable energy investments in 2022 were in Africa. It adds that modern renewables make up 11% of all electricity generated in very high HDI countries, but account for 2% of electricity in low HDI countries.
The graph below shows the carbon intensity of the energy system, both globally (dashed) and by HDI (solid coloured lines).

“Access to stable, non-polluting energy is crucial for advancing health and wellbeing,” the report says. It estimates that in 2022, 77 million people had no access to electricity – mainly in sub-Saharan Africa and south Asia – while millions of others only have access to “dirty” energy sources.
Biomass burning – which the report calls “highly polluting” – accounted for 92% of household energy in low HDI countries and 8% in very high HDI countries in 2020. Women and girls are often “tasked with household energy-related activities”, meaning they are disproportionately affected by air pollution-related diseases, the report notes.
Overall, air pollution caused by particulate matter with a diameter smaller than 2.5 micrometres (PM2.5) was responsible for 1.2 million deaths in 2020, down from 1.4 million in 2005, the report finds. “Reduced coal pollution contributed to about 80% of the decrease,” it adds.
The figure below shows the mortality rate due to PM2.5 in 2005, 2010, 2015 and 2020 for countries with low (top), medium (second from the top), high (second from the bottom) and very high (bottom) HDI levels.
The colour of each bar indicates which sector produced the pollution, for example light blue for agriculture and purple for households. The shading on each bar indicates the type of fuel.

“The uptake of clean energies has been unjust and way too slow,” Romanello told the press briefing.
However, Romanello said the report also gives reason for “hope”. For example, the report finds that employment in the renewable energy sector increased by 5.6% in 2021 reaching a record of 12.7 million employees.
The graph below shows employment in different renewable energy sectors (bars) and in fossil fuel extraction (orange dots).

‘Wrong direction’
The final section of the report focuses on finance. It finds that investment into low-carbon energy increased globally by 15% in 2022 to $1.6tn, exceeding fossil fuel investment by 61%. Meanwhile, lending to the low-carbon energy sector has “radically increased”, reaching near-parity with lending to the oil and gas sector.
However, the authors warn that financing to the fossil fuel sector is still on the rise. Over 2017-21, the 40 banks that lent most to the fossil fuel sector collectively invested $489bn annually in fossil fuels – a 52% increase from their 2010-16 lending – the report finds. In addition, global fossil fuel investment increased by 10% in 2022, reaching more than $1tn.
In 2020, 78% of the countries assessed generated collective fossil fuel subsidies of $305bn – a value higher than 10% of national health spending in 26 of the countries – the report adds.
It adds that the strategies of the world’s 20 largest oil and gas companies as of February 2023 would result in emissions surpassing levels consistent with limiting warming to 1.5C by 173% in 2040, if they were carried out as planned.
The report warns that inequalities between developed and developing countries “are aggravated by the persistent failure of the wealthiest countries to deliver the promised modest annual sum of $100bn to support climate action”.
However, it also highlights the “transformative health benefits that could come from the transition to a zero-carbon future”, and emphasises the need for a central role that the health community can play in securing these benefits.

UN chief warns climate crisis “in overdrive” as El Niño threatens to fuel the fire
The United Nations Secretary-General and foreign ministers from the UK, France and Spain have blamed the deadly wildfires engulfing Europe on climate change, using the disaster to renew calls for faster cuts to greenhouse gas emissions.
António Guterres told journalists on Friday that the “climate crisis is in overdrive”, adding that global heat seen so far is just a “warm up act” as a phenomenon known as El Niño intensifies “adding fuel to a planet already on fire”.
A new World Meteorological Organisation (WMO) report published on Friday predicts that the weather pattern will grow into a “strong event” between now and October, increasing the risk of higher than normal temperatures across much of the world and disrupted rainfalls.
“That risks shattering every seasonal record – and driving even more severe effects worldwide,” Guterres said.
El Niño builds on top of an already warming world, driven primarily by the burning of fossil fuels. A WMO scientist, who did not want to be named, told journalists that all the heatwaves and other climate impacts seen so far this year are “before the effects of El Niño are really kicking in at a global scale”.
Fossil fuellling the fires
Fires have broken out across much of Europe but are threatening the most people in the south-west of France near Bordeaux and in Central Spain near Madrid. Nearly a quarter of a million people have been evacuated in France with hundreds of homes destroyed while in Spain 80,000 people have had to leave their homes and at least 13 died in one village.
A scientific study published on Friday by the World Weather Attribution group found that man-made climate change made deadly fires in France twice as likely and those in Spain twenty times more likely. Smaller fires in the UK were not analysed by the study.
UN Climate Change leader Simon Stiell blamed fossil fuels for the fires, as well as storms in Chile and heatwaves in North America and Japan in recent weeks. “The climate alarm is blaring”, he said on Wednesday.
Guterres criticised new fossil fuel production projects and fossil fuel subsidies for causing hardship across the world. Discussing his speech, a senior UN official – who did not want to be named – said the subsidies amounted to trillions of US dollars a year and criticised pension funds and institutional investors, including insurance companies, for continuing to invest in fossil fuel projects.

Asked why world leaders and the public are not prioritising climate action, Guterres said they are distracted by wars in Ukraine, the Middle East, Sudan and elsewhere and sometimes forget “other aspects that are a sometimes even more dangerous threat”.
Also the fossil fuel industry and “some countries” are campaigning to pretend that climate change does not exist, he said, adding that the UN should be more active in “naming the situations as they are and the responsibilties as they are and mobilising the public opinion”.
After meetings in Paris and Madrid earlier in the week, the UK’s new foreign minister Ed Miliband issued joint statements with his French and Spanish counterparts – Jean-Noël Barrot and José Manuel Albares Bueno – calling on the world to reduce its dependence on fossil fuels.
They promised to do more to reduce emissions and protect their people and encouraged other governments to do the same.
The UK-French statement called on governments to publish UN climate plans, known as nationally determined contributions (NDCs), which are aligned with the Paris Agreement’s goal to limit global average temperatures to 1.5C above pre-industrial levels.
According to Climate Action Tracker, only three countries – the UK, Nigeria and Norway – have submitted NDCs with 2035 emissions reduction targets which are compatible with 1.5C. Fifty-two countries – including Egypt, Vietnam and Argentina – have yet to submit an NDC at all.
Defending science
Beyond action on emissions, the ministers also intervened in an ongoing dispute over the timing of the Intergovernmental Panel on Climate Change’s (IPCC)’s next flagship assessment.
Miliband and Barrot’s statement said they “underline the importance” of scientific report feeding into governments’ next global stocktake of progress on climate action in two years’ time, calling it a “critical input” to that process.
The timing of this report has been a contentious issue in government negotiations at the IPCC and at June’s climate talks in Bonn. While a group of nations calling themselves the “friends of science” want the report before the stocktake, others like Saudi Arabia and India have argued that this would make the report of a worse quality and less inclusive of developing countries’ scientists.
Science ‘under attack’ from fossil fuel interests at UN climate talks
The UK-Spanish statement weighed in less explicitly on this issue but said that they “recall the importance of scientific evidence and acknowledge the work of the IPCC in this respect.”
The British and French ministers said they would seek to accelerate reductions of emissions in methane, a particularly potent greenhouse gas, at COP31 in November. They encouraged governments “to work jointly to develop a marketplace for fossil fuels with near-zero methane intensity.”
Methane leaks from oil, gas and coal production are a major contributor to global warming. Over a 20-year period, methane traps around 80 times more heat than carbon dioxide.

The UK and Spanish statement emphasised the importance of supporting the Global South and underlined the need to mobilise sustainable financing “at scale with the challenge we face”. The previous UK government, in which Miliband was energy minister, cut climate finance to developing countries to pay for increases in military spending.
The UK government led by new Prime Minister Andy Burnham has yet to outline any major changes to climate finance in its two weeks in power but has announced it will convert some finance from grants to loans in order to free up money to subsidise bus travel in England.
More adaptation needed
Guterres said that “it is time to stop treating each disaster as an isolated tragedy and recognise the systemic risk that is unfolding before our eyes.” A recent study found that three-quarters of UK media reports about the British June heatwave did not mention climate change.
As well as reducing emissions, the UN Secretary-General called for measures to adapt vulnerable people to extreme heat. Specifically, he said that buildings should be built and retrofitted for extreme heat and that every city and country should have heat-health action plans and early warning systems. Over 250 cities have joined the UN’s ‘beat the heat’ initiative, he said.
The Portuguese diplomat called for governments and employers to do more to protect their workers from heat, criticising global fashion brands for not setting heat standards for the factories that supply them. “No one should have to risk their life to earn a living,” he said.

‘Ride the wave of momentum’: Australia announces once-in-a-decade Marine Parks Network review
In response to the federal government announcing its once-in-a-decade review of Australia’s Marine Parks Network, the following lines can be attributed to Elle Lawless, Senior Campaigner at Greenpeace Australia Pacific:
“Greenpeace Australia Pacific welcomes today’s announcement that the Albanese Government will review Australia’s Commonwealth Marine Parks Network. This is a rare, once-in-a-decade opportunity to strengthen our marine parks and ban industrial fishing in Australia’s marine protected areas.
“Australians would be appalled to know that more than half of Australia’s Marine Parks Network currently allows for extractive industries, like longlining, bottom trawling and oil and gas mining. These so-called ‘protected’ areas were designed to safeguard our beloved ocean wildlife and underwater ecosystems – that is what Australians expect. Damaging industrial industries should not be given a free pass to trawl, fish, drill or extract from our marine parks.”
“With the first Ocean COP just around the corner, and off the back of Australia’s move to ratify the Global Ocean Treaty earlier this year, the Australian government has a unique opportunity to ride the wave of this momentum and solidify itself as a true global ocean leader.
“Greenpeace Australia Pacific is calling for industrial activities to be banned from our protected waters and for at least 30% of Australia’s ocean to be protected as ocean sanctuaries. This review presents a rare opportunity to create more ocean sanctuaries, true blue havens where ocean life can recover, thrive and repopulate the surrounding waters.”

Factcheck: No, Europe is not having its ‘quietest’ year for wildfires
In recent days, prominent climate sceptics and rightwing commentators have shared charts on social media incorrectly implying that Europe is having its “quietest” year for wildfires in 2026.
These include Dr Matthew Wielicki, a former University of Alabama geochemist and self-described “professor in exile”, who was recently appointed by the Trump administration to lead the US Global Change Research Program.
However, these charts paint a misleading picture as they are skewed by encompassing the entirety of Russia in the data – including the vast plains of Siberia.
These charts also use data that include fires that are deliberately lit to manage cropland, which is a declining practice across much of Europe.
In this factcheck, Carbon Brief shows that the area burned by wildfires across the European Union in 2026 is second only to 2022 for this time of year.
The latest data from the European Forest Fire Information System (EFFIS) also shows that France has set a new modern record for area burned and Spain’s wildfire season is among the worst on record.
The fires have displaced more than a third of a million people across south-western Europe, while an impending heatwave has also raised fears of the fires worsening in the coming days.
‘Quietest year’
On 27 July, as wildfires raged across multiple European countries, former Conservative peer and climate-sceptic commentator Matt Ridley posted on Twitter that “2026 is the quietest year for wildfires in Europe by some distance”.

Ridley, who sits on the academic advisory council of the Global Warming Policy Foundation (GWPF), a UK-based climate-sceptic lobby group that refuses to reveal the sources of its funding, was responding to an article by Daily Telegraph columnist Tim Stanley.
Stanley’s column, headlined: “Climate change is real – and the right needs to get serious about it”, warned:
“This is no longer a matter of speculation: the wildfires of Europe, pitiless and persistent, are the way we live now.”
Ridley included a chart from Our World In Data, showing the cumulative area burned by wildfires by week for Europe. The chart puts 2026 as having the smallest area for this time of year in a dataset going back to 2012.
Ridley’s post was widely shared by prominent rightwing figures – including Richard Tice, deputy leader of the hard-right, climate-sceptic Reform UK party, former Conservative cabinet minister Jacob Rees-Mogg and multiple commentators.
Separately, Wielicki also shared a chart on Twitter to imply that wildfires in Europe are declining. Wielicki has previously claimed that the “science is not settled on climate change”.
The charts posted by Ridley and Wielicki both use data from the Global Wildfire Information System (GWIS). The GWIS category for “Europe” encompasses all the countries on the continent and includes the whole of Russia.
As a result, Russia accounts for about 74% of the area included in the GWIS definition of “Europe”.
Wildfires in Russia typically account for 80-90% of the burned area in the GWIS Europe dataset. In 2026, fires in Russia are substantially below average. Therefore, including Russia in this comparison creates the false impression that wildfire activity across Europe is unusually low.
Dr Calum Cunningham, a research fellow at the University of Tasmania’s Fire Centre, says that such claims are “highly misleading”, noting that “they rely on aggregating fire activity across an enormous and climatically diverse region”. He tells Carbon Brief:
“A relatively quiet season in Russia can easily mask an exceptionally active season in France or Spain. If the analysis is focused on the regions actually experiencing the current fires, the picture is very different.
“The reality is that western Europe has experienced an extraordinary sequence of climate conditions this year.”
In contrast, the EFFIS provides a subset of wildfire data specifically for the area covered by the 27 nations of the EU, which, therefore, excludes Russia.
Another difference between the two datasets is that GWIS monitors all fires – including those on agricultural land that are intentionally set alight. The burned area as measured by GWIS contains significant cropland area.
By contrast, EFFIS uses land-cover data and other information to filter specifically for forest fires.
Looking at the EU-only data from EFFIS reveals that Europe is far from having its “quietest” year. The bloc’s burned area, as of 29 July, is almost 435,000 hectares (ha) – second only to 2022 for this time of year.

Notably, Wielicki has actually continued to post charts based on GWIS data, even after acknowledging that “includ[ing] all of Russia, including vast areas of Siberia…isn’t a good proxy for Europe”.
French fires
Even looking at EU-wide data misses the scale of this year’s wildfires for some individual countries.
The chart below shows the surge in burned area in France since mid-July.
For much of the first half of the year, the country was having a wildfire season that was only slightly above average in terms of total burned area. However, a notable uptick began in the first week of July.
The third week of the month saw France break its previous cumulative annual record by more than 19,000ha. That gap has widened as the fires continue to burn; as of 29 July, the cumulative burned area in France during 2026 was nearly 24,700ha above the previous record.

The fires in France follow a record-breaking June heatwave that “dried out vegetation across the region, allowing fires to spread quickly”, wrote the New York Times.
On 27 July, French president Emmanuel Macron called a “crisis cabinet meeting” in order to address the fires “ravaging several areas of south-west France”, said France 24.
More than 220,000 people have been evacuated due to the Gironde fire, west of Bordeaux, in “what may be France’s largest peacetime evacuation”, reported the Associated Press.
In the Conversation, Cunningham and two other University of Tasmania researchers write that evacuation orders “protec[t] human lives, but makes it more likely houses and other structures will burn if there’s no one to defend them”. They add:
“There is little doubt climate change has made France and Spain’s wildfires worse. They represent yet another reason to redouble our efforts to tackle climate change and stabilise our climate.”
Central Spain scorched
While Spain’s fire season has not broken records in the same way that France’s has, it is on track to be among the worst since EFFIS began reporting data in 2006.
The chart below shows the rapid increase in burned area in Spain since 8 July. The latest data from EFFIS reveal that, as of 29 July, Spain has almost matched its previous record at this point in the year. It is also nearly five times the average area burned for this time of year.

In Spain, the wildfires have been concentrated in the central part of the country, near Madrid.
BBC News reported that the fires outside the capital have burned “an area more than twice as large as the city itself”.
Nearly 90,000 people were forced from their homes in central Spain by the fires, said the Associated Press.
Pedro Sánchez, Spain’s prime minister, called the fires a “painful expression” of climate change.
Meanwhile, the UK, French and Spanish governments have issued joint statements this week in response to the fires. The UK/Spain statement begins:
“This summer’s wildfires demonstrated that climate change was now a national security emergency facing Europe and threatening our way of life.”
