As temperature records are shattered, ice rapidly melts and extreme weather events worsen, many people around the world say they are feeling more worried about climate change.
Researchers call this growing phenomenon “climate anxiety”.
A new analysis examines 94 studies focused on climate anxiety, involving 170,000 people across 27 countries, to explore who it is most likely to affect and what its possible consequences could be.
It finds that those who are more likely to experience climate anxiety include women, young adults, people with “left-wing” views and those expressing “concerns” about nature or the “future”.
Climate anxiety is negatively related to wellbeing, according to the analysis, but positively related to participating in climate action, such as activism and behaviours to reduce emissions.
Below, Carbon Brief explains the findings in more detail.

What is ‘climate anxiety’?
“Climate anxiety” can be described and defined in various ways.
The research, published in the journal Global Environmental Change, considers the term “climate change anxiety” to “broadly refer to people’s feelings of anxiety and/or worry related to climate change”.
This is based on two established definitions, explains study lead author Dr Clara Kühner, a researcher of climate change and psychology at the University of Leipzig, Germany. She tells Carbon Brief:
“There is a discussion in the scientific community about what exactly constitutes climate change anxiety.”
The first definition comes from a 2023 research paper, which describes climate anxiety as “persistent anxiety (apprehensiveness) and worry about climate change”.
The second comes from the American Psychological Association, which in 2020 used the term “eco anxiety” to describe “any anxiety or worry about climate change and its effects”.
Kühner explains that “eco anxiety could be interpreted as being more broadly related to the ecological crisis…but [the American Psychological Association] describe it as any anxiety or worry related to climate change”.
Her team noticed that there has been an “increasing amount of research” into climate anxiety over the past few years, she adds:
“Research on the topic has exploded. That’s a signal that it’s very relevant to researchers, but also to society and the public.
“But it was very difficult to get an overview of this research because it was scattered across different disciplines, not only psychology, but also public health and sociology. And so it was difficult to really know how much is out there. That’s when we thought: ‘OK, let’s put all of that together in a quantitative meta-analysis to get an overall perspective on the topic.’”
For the meta-analysis, Kühner and her team searched online records, scoured scientific conference agendas and contacted other scientists to try to identify all published and upcoming studies looking into climate anxiety.
They focused on studies that had conducted surveys with people self-reporting symptoms of climate anxiety. They also restricted their search to “correlational studies” looking at the links between self-reported climate anxiety and various factors, such as gender, age or political beliefs.
In addition, they only included studies involving people over the age of 18.
In total, the meta-analysis identifies 94 climate anxiety studies, involving 170,000 people in 27 countries.
Some 81 of these studies were published after 2020, according to the researchers – reflecting the surge of research interest into the topic over the past few years.
Who suffers from climate anxiety?
As part of the meta-analysis, the researchers looked across the 94 studies to identify what characteristics are most highly associated with having climate anxiety.
From this, the meta-analysis finds that those more likely to report feeling climate anxiety include:
- Younger adults
- Women
- People with a “left-wing” political orientation
- People concerned about the environment
- People concerned about nature
- People concerned about the future
- People who believe in climate change
- People who have been exposed to climate impacts
- People who are regularly exposed to information about climate change (such as climate scientists, journalists and teachers)
The graphic below shows the relative “effect size” of each of these characteristics, according to the study, with -0.9 illustrating the trait is less related to climate anxiety and 0.9 indicating it is more related.
On the graphic, the centre of each blue bar represents the effect size, with the start and end showing 95% confidence intervals.
By contrast, people with the opposite characteristics to those listed above – for example, those that are older, male or hold “right-wing” political views – are less likely to report feeling climate anxiety, according to the research.
The study only examines the correlations between feeling climate anxiety and various human characteristics – and does not look into the reasons why different groups of people may be more likely to experience climate anxiety.
One of the research papers cited in the meta-analysis finds that people under the age of 25 who reported climate anxiety were likely to have feelings of “betrayal” aimed towards older generations and to perceive governmental response to climate change as “inadequate”.
On gender, previous research – not cited in the meta-analysis – has found that women are more likely than men to suffer from mental illness following extreme weather events – and face higher health risks from climate change in general.
The meta-analysis does not look into how being transgender or non-binary could be associated with climate anxiety, but researchers have previously argued that these groups – along with other people who might identify as LGBTQ+ – are likely to face disproportionate climate risks.
The meta-analysis also does not investigate where in the world levels of climate anxiety could be the highest.
Most of the papers included in the meta-analysis were conducted in the global north.
Out of the 94 studies, 56 were conducted in Europe, 12 in North America, seven in Australia and New Zealand, seven in Asia, one in Africa and one in South America. (A further 10 spanned multiple continents.)
This “largely reflects the general dominance of western research in mainstream psychological and behavioural studies” – rather than a weakness of the authors’ methods, says Prof Kim-Pong Tam, an environmental psychologist from the Hong Kong University of Science and Technology, who was not involved in the meta-analysis.
He describes the findings as “very significant”, adding:
“It should be noted that the pattern revealed in this meta-analysis does not necessarily indicate that the phenomenon of interest has rarely been studied in the global south or outside of western societies.
“It is common practice for authors conducting a meta-analysis to focus on publications in the language(s) in which they are proficient. This implies that studies published in non-English languages (usually in local journals), if any, are excluded.”
Dr Charles Ogunbode, an associate professor in psychology specialising in how people respond to environmental change at the University of Nottingham, UK, agrees that the “lack of studies from Africa and other parts of the global south is not a unique weakness of this article”.
He says that the “climate anxiety discourse is western-centric”, explaining:
“Outside of western cultures, climate anxiety may not feel like an especially useful concept for making sense of local lived realities. For example, one study found that feelings of anger and grief regarding climate change are more prominent in Turkey. Another study conducted with young people in three African countries found the predominant emotions to be akin to a helpless pessimism. Similar observations were made in Ecuador.
“It is, of course, valuable to have a comprehensive study on climate anxiety, but the western-centric nature of the concept means that we end up missing out on the nuanced cross-cultural dimensions of emotional responses to climate change.”
What are the consequences of climate anxiety?
As well as examining what human characteristics are most associated with climate anxiety, the meta-analysis explores what consequences are most associated with the phenomenon.
These consequences are grouped into three categories: “wellbeing”, “climate change emotions” and “behaviour”. (The meta-analysis considers “wellbeing” to be “how individuals evaluate the quality of their own lives, including experiences such as life satisfaction”.
The meta-analysis finds that feeling climate anxiety is associated with poor wellbeing and negative feelings about climate change.
However, climate anxiety is also associated with “pro-environmental behaviours”, such as saving energy at home, as well as participating in community activism and showing support for government pro-climate policies. Kühner explains:
“We found that climate change anxiety is a double-edged sword. It [is] related to poorer wellbeing and to more psychological strain. On the other hand, it [is] positively related to different forms of pro-environmental behaviour.
“On the one hand, it could make you feel uncomfortable. But, on the other hand, it may trigger significant action.”
How does climate anxiety differ from general anxiety?
One of the goals of the meta-analysis is to investigate if climate anxiety is a distinct psychological phenomenon – or merely reflects the broader recent trend of rising levels of anxiety across many parts of the world, particularly for younger demographics.
To do this, the researchers carried out a “meta-regression analysis”, a statistical method for, in this case, investigating the size of the impact of various factors on having climate anxiety.
This analysis finds that the characteristics associated with climate anxiety, such as being a young adult or female, as well as its associated consequences, such as taking action to reduce emissions, were “uniquely related to climate anxiety above and beyond generalised anxiety”. Kühner explains:
“From a methodological point of view, this means that these are distinct constructs, not that people who are generally more anxious are also more anxious about climate change.”
This finding could have implications for how both medical professionals and the public view climate anxiety, she continues:
“Sometimes, climate change anxiety is treated like a disease that has to be cured. And it’s not. It’s a normal healthy reaction to an actual threat.
“I think it’s important for policymakers, also journalists and politicians, not to pathologise climate change anxiety, but to interpret it as a functional reaction to something that is actually happening. Instead of offering mental-health support for how to get rid of this, we need more opportunities to channel this anxiety into climate change action.”
In some cases, climate anxiety can cause poor mental health, she adds:
“If [climate anxiety] impairs your daily functioning or affects your sleep, you definitely need mental-health support to cope with these strong emotions.”

Israel’s bombardment of Gaza during the conflict that broke out in October 2023 has wrecked progress towards adapting the enclave to climate change and left two million Gazans vulnerable to heatwaves, drought and disease, the Palestinian Authority (PA) said in a new climate plan submitted to the United Nations.
Palestine’s third nationally determined contribution (NDC), uploaded to the UN climate body’s website this week, says that while “the aggression on the Gaza Strip did not make the climate worse”, “it removed the housing, water and sanitation systems, health facilities, energy networks, roads and livelihoods through which people absorb a climate they were already struggling with.”
The 91-page document lists the types of infrastructure it says Israel has destroyed and notes how the destruction will worsen the impacts of climate change. It says the bombing of hospitals and rising hunger have make it harder for Gazans to cope with the health impacts of climate-driven heatwaves and waterborne diseases.
The destruction of water tanks, boreholes and desalination plants, meanwhile, have left Gazans struggling with the effects of water shortages and drought, while mass unemployment reduces people’s ability to afford climate-driven price rises. The erasure of most of the Strip’s homes makes it more difficult for people to avoid the sun’s increasing heat, the NDC said.
Many Gazans are now living in the ruins of collapsed buildings or in makeshift shelters and tents that offer little or no protection from high temperatures.
Palestine’s previous goals to cut emissions and adapt to climate change in Gaza, expressed in its last NDC five years ago, were based on a pre-war baseline that “no longer describes anything that exists”, the NDC says. Progress made since 2021 has now been destroyed, it adds.
Green reconstruction of Gaza
Instead of continuing to aim for these adaptation and emissions-reduction goals, the PA is now calling for the green reconstruction of Gaza. It says buildings should be constructed again in an energy-efficient manner with solar panels and served with modern water, waste and transport systems.
While the PA, controlled by the Fatah political party, continues to claim legitimate control of Gaza, the strip was effectively governed by Fatah’s rival Hamas between 2007 and the recent war. Control is now split between Israel and the political wing of Islamist militant group Hamas, after a US-backed ceasefire took effect in October 2025, although a UN-backed committee plans to take over.

More support needed to power Africa’s food systems with renewables, experts say
Renewable energy could help African food businesses boost productivity and competitiveness, but the upfront cost, fragmented markets and limited financing stand in the way
The United Nations, European Union and World Bank have jointly estimated that Gaza needs $71.4 billion of investment in the next two years to recover and build back. This process should be Palestinian-led, they said in April.
But US President Donald Trump has said the US should “take over” and “own” Gaza and redevelop it as the “Riviera of the Middle East”. Israel’s right-wing prime minister Benjamin Netanyahu has said that Israel should control the territory with civil administration managed by Palestinians favourable to Israel.
With occupation, targets conditional
In the other part of Palestine, the West Bank, the Palestinian Authority carries out some government functions, but ultimate control rests with Israel, which has occupied the West Bank since 1967.
Because Israel controls planning in most of the West Bank, the NDC argues that the PA cannot pursue all the climate projects it wants. In addition, Israel restricts the movement of PA officials, making data collection difficult, and controls the West Bank’s electricity supply meaning that the PA cannot control whether it comes from dirty or clean sources of energy.
Given this situation, the NDC says that all of Palestine’s new climate targets are conditional but it will aim to reduce emissions 12.8% below a business-as-usual baseline by 2035 and 17.1% by 2040. If the Israeli occupation ends and Palestine regains full sovereignty over its land and resources, it will aim for reductions of 15.1% and 19.1% by 2035 and 2040 respectively under an “independence pathway”.
That could allow, for example, for greater electrification and reducing emissions per unit of growth, the document said.
To achieve the 2035 emissions-reduction target and adapt to the impacts of climate change, the PA says it needs $8.6 billion in total. This funding would be spent on measures like encouraging solar farms and rooftop solar and scaling up solar water heating to cover four-fifths of households. To complement the planned increase in solar power, the authority wants to modernise the electricity grid and install battery storage.
In the transport sector, it aims to promote the uptake of electric vehicles, develop bus rapid transit corridors and scrap old polluting trucks and buses. In Gaza in particular, it wants to deploy 66 electric buses when the conflict ends.
To adapt to climate-driven drought, the NDC includes initiatives to reuse wastewater through treatment plants, build desalination plants in Gaza to remove salt from seawater, and promote irrigation for farmers.
The new climate plan was prepared by Palestine’s Environment Quality Authority, with support from the United Nations Development Programme and the governments of Britain and Spain.
The United Nations recognised Palestine’s statehood in 2012 and it joined the UN’s climate convention and signed the Paris climate agreement – which requires countries to submit more ambitious NDCs every five years – in 2016.
The Israeli foreign ministry did not respond to a request for comment. But in late 2024, then Israeli climate envoy Gideon Behar told Climate Home News that the war and the resulting environmental destruction in Gaza was the fault of Hamas.

Solar power generation in the UK reached a new record over the summer of 2026, as temperatures across the nation soared, according to new analysis by Carbon Brief.
Collectively over June, July and August, solar farms and rooftops generated 8.8 terawatt-hours (TWh) of electricity in the UK*, as shown in the chart below.
Speaking to Carbon Brief, Chris Hewett, chief executive of trade association Solar Energy UK welcomed the new record, adding that it was driven by “clear skies and continued growth in deployment”.
This surge in generation took place amid the hottest summer on record in the UK, with five heatwaves between May and August.
Summer 2026 was the sixth sunniest on record, with more than 620 hours of sunshine, according to the Met Office. England and Wales – which experienced the most extreme heat – saw their second-sunniest summers on record.
June 2026 was the hottest June in England since records began in 1884, according to Met Office data, while Wales and the UK as a whole experienced their second-warmest June.
It was the driest July for England and Wales since records began in 1836, with some parts of London seeing no rain at all in the month, while Wisley in Surrey had no rain for 62 days.
In England, temperatures peaked at 38.1C at Kew Gardens in London on 13 August.
According to the Met Office, this summer’s record mean temperature was made 130 times more likely by climate change.
Amid these hot and sunny months, solar power generation increased 23% from the same period in 2025. This is double the level of solar generation over the summer of 2021, according to Carbon Brief analysis.
While solar panels can be affected by periods of extreme heat, the longer hours of daylight and higher levels of irradiation over the summer more than offset any efficiency losses.
June, July and August all saw solar set new monthly records for solar generation – July saw the highest solar generation in a calendar month ever, with 3.3TWh meeting 15% of overall electricity demand for the month.
As of the end of August, the total UK solar generation in 2026 stood at 17TWh – 13% higher than the same point in 2025.
The number of solar farms and rooftop installations has grown substantially in recent years, helping to boost generation. Domestic rooftop solar accounts for around 29% of total capacity.
In 2025, the UK’s solar capacity reached 21 gigawatts (GW) by the third quarter of the year, according to UK government figures. This is a jump of 3GW, or 18%, year-on-year, as Carbon Brief reported in January.
(Capacity is the maximum output possible from an electricity generation, whereas generation is what was produced over a certain time period, such as a day, month or year.)
According to the University of Sheffield, the installed solar capacity is now nearly 24GW.
This includes nearly 172,000 solar installations that have been fitted across the UK since the start of 2026, according to recent government figures. In July alone, more than 19,800 rooftop solar panels were installed – the equivalent of one installation every two minutes.
In total, nearly 1.7m households in the UK now have solar panels installed.
Over 26 heatwave days this summer – periods of at least three days when temperatures exceed the Met Office’s county-level heatwave temperature threshold – UK households with rooftop solar panels avoided an estimated £86.7m in electricity costs, according to analysis by Utility Bidder.
Talking about the surge in solar generation this summer, Hewett says:
“[It] not only kept bills down for people with solar and batteries in their homes, but helped keep overall power prices much lower than they would have been if Britain had been relying on more gas generation during the day”.
Despite the record generation, no new half-hourly solar power output record was set in the summer of 2026. This still stands at 15.2 megawatts (MW) on 23 April 2026.

Farmers around Europe are dealing with the aftermath of a summer of extreme heat, drought and wildfires that were exacerbated by climate change.
Human-caused climate change is increasing the severity and likelihood of many extreme weather events around the world, which is increasing volatility for food producers.
This summer resulted in, for example, shrunken potatoes in the Netherlands, reduced carrot harvests in France, dried-up rice fields in Italy and scorched olive groves in parts of the Mediterranean region.
Global food prices are currently at their highest level since early 2023 due to “heatwaves and energy price dynamics”, according to the UN Food and Agriculture Organization.
Other factors such as blocked fertiliser supplies in the Strait of Hormuz and high fuel costs have also played a role in this year’s agricultural outputs.
In the six charts below, Carbon Brief provides a snapshot of the impact this summer’s extremes are considered to have had on crop production and yields across Europe.
1. Most EU countries expect to see declines in cereal production this year
2. Most countries are recording reduced crop yields
3. Around €2bn worth of cereal losses after June heatwave
4. UK yields of wheat, barley and oats are all due to drop in 2026
5. Maize production in France is due to hit a four-decade low
1. Most EU countries expect to see declines in cereal production this year
France, in particular, will see heavy losses in the amount of cereals – such as wheat, barley and oats – it produces this year, according to European Commission data.
French cereal production is expected to drop by almost 8 megatonnes (Mt) in 2026, compared to 2025.
The chart above shows that most European countries, aside from Bulgaria, will also see production losses this year.
Germany is due to see the second-largest losses in production, dropping by almost 4Mt compared to 2025.
Prof Til Feike, a cropping systems expert at the Julius Kühn-Institut, says many areas in Germany and Austria, as with other parts of Europe, have been “hit hard by a long-lasting dry period in combination with record-high heatwaves”.
This has resulted in dry grassland for animals and lower yields of maize, which is a “key fodder crop” for livestock. He tells Carbon Brief:
“In the long run, farming must adapt better to more extreme weather conditions, not only heat and drought, but also prolonged wet periods. So, there is no one-fits-all solution for climate change adaptation.”
2. Most countries are recording reduced crop yields
Heat and a lack of water have “substantially worsened” crop expectations this summer in western and most of central Europe, according to a recent bulletin from the EU Joint Research Centre.
Yields are expected to be “significantly reduced”, with local crop failures “likely” in areas such as France, southern Germany, northern and central Italy, and Hungary, it added.
The chart below shows that yields of cereal grains – which, here, refers to the tonnes of a grain grown per hectare of land – are expected to fall in most EU countries in 2026.
Slovakia, Austria and Hungary are expected to see the largest declines in cereal yields, reducing by more than one tonne per hectare in 2026 compared to 2025.
The recent EU bulletin noted that irrigated crops performed well in Portugal this summer – the country with the largest yield increases. Other crops relying on rainfall showed growing signs of heat stress, it added.
3. Around €2bn worth of cereal losses after June heatwave
The record heatwave that hit many parts of Europe in June contributed to an estimated €2-2.3bn in cumulative grain production losses, as shown in the chart below.
The intense June heat in western Europe would have been “virtually impossible” just 50 years ago, according to a rapid climate attribution study. It was the region’s hottest June on record.
The Energy & Climate Intelligence Unit (ECIU) thinktank analysed June and July 2026 grain forecasts from Coceral, a European grain traders association.
ECIU estimated lost supply by multiplying the change in tonnes of grains between these two months by prices for harvest delivery in 28 European countries.
Major grain producers France, Germany, Hungary and Spain accounted for 86% of the lost revenue, according to the ECIU.
Extreme heat is also expected to have a wider economic impact across the continent. Analysis from Triodos Bank found that this summer’s extreme weather could reduce the EU’s gross domestic product (GDP) by around 1% this year, or around €180bn.
4. UK yields of wheat, barley and oats are all due to drop in 2026
If current trends continue, the average yields for cereals and oilseeds will result in the UK’s worst harvest since detailed records began in 1984, according to ECIU.
Barley yields could fall by 15%, oats by 14% and wheat yields by 6% year-on-year, according to 2026 harvest surveys from the Agriculture and Horticulture Development Board, a non-departmental public body that provides agricultural data to the UK government.
ECIU said that, even if the situation improves, this year is still expected to be one of the five worst harvests on record. This means that four of the five worst harvests in the UK have occurred in the past decade.
Consumers will likely see higher prices and/or smaller vegetables in supermarkets as a result, Tim O’Malley, chairman of UK company Nationwide Produce, told BBC News in August.
Other crops, such as berries, have grown successfully in the extreme heat. But the Guardian noted fears this could dip later this year “as plants become exhausted from heavy cropping during the heatwave”.
5. Maize production in France is due to hit a four-decade low
France has been acutely affected by this summer’s extreme weather, with more than 7,300 excess deaths during heatwaves and a record number of weather stations recording temperatures of above 40C.
The country is the EU’s largest agricultural producer, but heat, drought and wildfires have affected many crops.
The chart below shows that maize production is set to drop by more than one-third (35%) year-on-year.
This could result in France’s lowest maize production since 1980, according to data from Agreste, the country’s agriculture ministry’s statistics service.
Due to the heat, “record-early” grape harvests have also been recorded in various parts of the nation since mid-July, reported Le Monde. In some cases, this means “smaller, less juicy grapes, which will yield less wine”, explained the newspaper.
6. Declines in EU grains since 2025
Overall in the EU, data and projections indicate declines in the output of cereal grains this year.
Cereal production is set to fall by 9% compared to 2025, according to the European Commission.
Just one year in the past decade – 2024 – recorded lower production levels.
Maize production is set to be particularly affected, with projections indicating a 13% drop, to 52Mt – the lowest level in the EU since 2007.
