Fires in the Amazon drive record-shattering global forest losses in 2024
Loss of tropical pristine forests alone reached 6.7 million hectares (16.6 million acres), an area roughly the size of Panama, marking an 80 per cent spike compared to 2023. One of the central drivers of these staggering numbers was Brazil, the host of the next global climate summit in November, struggling to contain fires in the Amazon amid the worst drought ever recorded in the rainforest.
According to the data, issued by the World Resources Institute and the University of Maryland, the rate of tropical primary forest loss in 2024 was the equivalent of losing 18 soccer fields of trees per minute.
Canada and Bolivia, along with myriad other countries, were also on the list of those ravaged by wildfires, with both tropical and boreal forests seeing huge impacts from fires.
It was the first time the annual report showed fires as the leading cause of tropical forest loss, a grim milestone for a naturally humid ecosystem that is not supposed to burn.
"The signals in these data are particularly frightening," said Matthew Hansen, the co-director of a lab at the University of Maryland that compiled and analyzed the data. "The fear is that the climate signal is going to overtake our ability to respond effectively."
Globally, researchers estimated that more than 4.1 gigatonnes of greenhouse gases were released due to forest fires last year — more than four times the emissions released from air travel in 2023.
Bolivia overtook the Democratic Republic of Congo as the second country with the most tropical forest loss despite having less than half the amount of forest as the African nation, which also saw a spike in forest loss last year.
Bolivia's forest loss surged by 200 per cent in 2024, with a drought, wildfires and a government-incentivized agricultural expansion as the leading causes. In regions full of tropical forests, fire is used to clear lands for agricultural expansion, sometimes cutting into protected areas or causing illegal deforestation.
One region in southern Bolivia bucked the trend of forest loss: Charagua Iyambae, a protected, autonomous Indigenous territory, which was able to keep the country's record fires at bay through land-use policies and early warning systems.
The Charagua Iyambae region includes five million hectares of forest, and recent protection laws have strengthened the Guaraní Indigenous people's management of the lands, allowing them to better resist agricultural expansion.
Southeast Asia also saw glimmers of hope, with Malaysia, Laos, and Indonesia all posting double-digit decreases in primary forest loss — something the report credits to domestic conservation policy, combined with efforts by communities and the private sector, effectively containing fires and agricultural expansion.
Countries hit hard by fires
Latin America was hit particularly hard, the report said, with the Amazon biome hitting its highest level of primary forest loss since 2016.
Brazil, which holds the largest share of the world's tropical forests, lost 2.8 million hectares (6.9 million acres), the most of any country. It was a reversal of the progress made in 2023 when President Luiz Inacio Lula da Silva took office promising to protect the world's largest rainforest.
"This was unprecedented, which means we have to adapt all our policy to a new reality," said Andre Lima, who oversees deforestation control policies for Brazil's Ministry of Environment, adding that fire, which was never among the leading causes of forest loss, is now a top priority for the government.
Increased forest loss in Mexico, Peru, Nicaragua, and Guatemala was spurred largely by wildfires and fires started for agricultural expansion, the report found. Conflicts in Colombia and the Democratic Republic of Congo also boosted deforestation rates, as armed groups used up natural resources.
5.2 million hectares in Canada
Outside the tropics, boreal forests, which evolved with seasonal fires, also posted record-high tree loss in 2024, the data showed, with Canada and Russia each losing 5.2 million hectares (12.8 million acres) in 2024 as wildfires got out of control.
It's part of a dismal trend for Canada. Data from the World Resources Institute published last year found that Canada's devastating 2023 wildfire season accounted for more than half of that year's global forest loss due to fire.

More than half of all the forest lost to fire last year was in Canada thanks to an unprecedented wildfire season, according to an annual survey published by the World Resources Institute.
In 2021, more than 140 world leaders, including Canada, signed the Glasgow Leaders Declaration reaffirming a promise to halt and reverse forest loss by 2030. But this new data suggests the global community is far off track in achieving that goal.
Rod Taylor, the global director for forests at the WRI, said that as leaders descend on the Amazonian city of Belem for the next climate summit, he would like to see countries make progress in introducing better funding mechanisms for conservation.
"At the moment," he said, "there's more money to be paid by chopping forests down than keeping them standing."

Globe Climate: The rise of weather content on social media
If you're reading this on the web or someone forwarded this e-mail newsletter to you, you can sign up for Globe Climate and all Globe newsletters here. Good afternoon, and welcome to Globe Climate, a newsletter about climate change, environment and resources in Canada. A manatee was recently spotted off the coast of Massachusetts for the first time in almost a decade. The threatened species usually makes its habitat in warmer southern Gulf waters, so scientists want to monitor its condition to see if a rescue is necessary. In 2008 and 2009, different manatees were sighted in Cape Cod Bay – the furthest north the animals have ever been identified. Both were eventually rescued. Anyone who sees the manatee is asked to document their GPS position and call the stranding network hotline, (508) 743-9548. Now, let's catch you up on other news. For this week's deeper dive, we closer look at the online world of watching weather. How often do you check your weather app? Or... weather apps? Online culture reporter Samantha Edwards recently took a deep dive into the new big world of weather data. Once the domain of professionals, climate information gathered from satellites and radar models are now easily accessible online, giving amateur forecasters an unprecedented amount of raw data. 'I immersed myself into the digital world of weather nerds, amateur forecasters and content creators. I joined niche online forums, subreddits and Facebook groups, subscribed to YouTubers who livestream during extreme weather events, and followed weather influencers,' she wrote in the morning update newsletter. With a plethora of new weather apps, we have access to real-time information that can help us better plan our lives and time outdoors – from where there will be heavy rain to extreme heat. On Reddit and niche online forums, weather nerds analyze and debate the output of forecasts. On YouTube and TikTok, 'storm streamers' go live for hours during extreme weather events, providing real-time updates and sharing on-the-ground photos sent in from their devoted followers. But the flood of data can also consume us, lead to misinformation and heighten climate anxiety while at the same time diluting important updates about flooding and wildfire threats. For the past few summers, Aspen Murray has started to check a new data point every day on her weather app: air quality. 'Getting accustomed to checking the air quality has been something that's really made me think more about my climate anxiety,' she said. 'Growing up, that's something that I never would have thought of or worried about.' Experts also warn that the overexposure to weather warnings, especially if they're poorly worded or not local, can lead to 'alert fatigue' and may result in tuning out crucial information. Plus, during extreme weather events, disinformation from high-profile conspiracy theorists is drowning out emergency response efforts. On Facebook, Samantha stumbled upon a group called Ontario Storm Reports, which was started by the former storm chaser Adam Skinner and now has tens of thousands of members. He says that the majority of people who post in the group, and also watch his livestreams during severe weather, have weather anxiety but find the knowledge more comforting. 'The unknown is much more scary,' he said. Sarah Goodman: Ottawa must prioritize climate tech in Canada's new defence strategy Stephen Maher: The people opposing Nova Scotia's ban on accessing the woods don't understand our culture Julia Zarankin: To my surprise, I learned that birding can be an adrenaline-fuelled extreme sport Conservatives plan national campaign to scrap zero-emission vehicle mandate Conservative Leader Pierre Poilievre pledged that his party will embark on a national campaign to push the Liberal government to scrap the policy he's dubbed the 'Carney tax.' Poilievre led the charge as the Conservatives attacked the consumer carbon price over the last two years, which eventually played a role to end the so-called carbon tax earlier this year. Now the Conservative leader claims the Liberal EV mandates 'would literally erase many small towns from the map.' We've launched the The Climate Exchange, an interactive, digital hub where The Globe answers your most pressing questions about climate change. We have been collecting hundreds of questions and posing them to experts. The answers can be found with the help of a search tool developed by The Globe that makes use of artificial intelligence to match readers' questions with the closest answer drafted.

Climate survivor stories spotlit in new Museum of Vancouver journalism project
The Museum of Vancouver is seen in this undated file photo. (Museum of Vancouver/Facebook) A new six-year journalism project involving the University of Victoria and the Museum of Vancouver hopes to share the voices of people directly affected by climate disasters around the world. Funded by a $2.5 million Social Sciences and Humanities Research Council grant, From Catastrophe to Community: A People's History of Climate Change will train 500 students and journalists to document the experiences of 1,000 climate disaster survivors. The stories will be shared across documentaries, news features, an anthology and a travelling museum exhibition set to launch at Winnipeg's Canadian Museum for Human Rights and the Museum of Vancouver. Viviane Gosselin, director of collections and exhibitions at the Museum of Vancouver, says the project aims to highlight the voices of those often lost in the rush to report on damage and interview the experts as climate events like forest fires and flooding become more frequent. 'Numbers are important, they help us understand the scale of the problem, but it's stories that really move people,' says Gosselin. 'Stats can't communicate human textures – the sights, the sounds, the tough choices, and the emotions that come with surviving and rebuilding your community, and yourself, after a disaster.' The initiative is the latest phase of the Climate Disaster Project, launched by University of Victoria writing professor Sean Holman in 2021. The project has trained over 250 students in trauma-informed journalism techniques and created over 320 climate survivor stories, delivered in the form of exhibitions, news articles and a documentary stage play. 'Our students learn how to work with survivors to co-create oral histories about their experiences, but not just their experiences, who they are as people, the places that they live, the help that they received, didn't receive, gave to others, gave to themselves,' says Holman. Those interviewed will be questioned on what they think can be done to help people like themselves in the future, and what they think can be done to assist in solving climate change issues. The focus of the project is not just to document the powerful stories, but to use them to inspire change and a desire to assist within the museum-goers and news readers, says Gosselin. 'We don't want people leaving with a sense of helplessness, we want them to take away real examples of communities rebuilding, adapting, and advocating for change,' she says. 'The hope is to turn that awareness into action, so visitors see themselves as part of the global climate story and feel inspired to respond in ways that restore dignity, and strengthen connections with those most affected.'

A look at how wildfire predictions held up throughout the years
The Mount Underwood wildfire is seen in this handout photo, southwest of Port Alberni, B.C., on Tuesday, Aug. 12, 2025. THE CANADIAN PRESS/Handout — BC Wildfire Service (Mandatory Credit) As Canada's forests burn, climate change scientists warn the increasingly warm planet will continue to take part in fuelling more frequent and violent wildfires. That is their forecast now, but how did their predictions hold up over the past decades? 'We are following the trend that scientists have predicted for some time,' says the director of research on adaptation at the Canadian Climate Institute Ryan Ness. CTV News archives shows that research two decades ago linked climate and a rise in fire frequencies. A 2006 television report points to a study that concluded new evidence showed climate change, not forest management and logging, was the main factor behind a spike of wildfires in California. 'We see this increase in fire frequency is well correlated with warming temperatures and the arrival of earlier springs in the last 16 or 17 years compared with previous decades,' said fire ecologist Thomas Swetnam, at the time. Ten years ago, as 196 countries signed on to the Paris Climate Agreement that aimed to curb global warming, a study in the Climatic Change journal projected that the annual frequency of fire spread days in Canada could increase by 35 to 400 per cent by 2050, with the greatest increases in Alberta and Saskatchewan. 'We can look back to papers published in the 1990s that predict an increase in area burned mainly because of climate change and rising temperatures,' says research scientist at the Canadian Centre for Climate Modelling and Analysis, Nathan Gillett. Statistics from the Canadian Interagency Forest Fire Centre (CIFFC) show that trend is proving to be a reality on the ground, not just a hypothesis. 'Winters are shorter, there is less snow to melt and keep our forest moist in the spring. Extreme heat further dries out the forests and turns them into fuel for intensifying wildfires,' says Ness. The Gault Nature Reserve, a McGill University-owned site an hour's drive from Montreal, aims to protect more than 1,000 hectares of natural forest and a trail network. Evidence of the dry conditions is on display. 'It can really spark, and you never know the consequences of throwing a cigarette or a campsite that is not well maintained,' says McGill's David Maneli, associate director at the reserve. To avoid risks, smoking is banned on the site. Maneli also says hikers who come to take in the majestic sights on trails that lead them to the top of a mountain, also learn valuable lessons about the need to protect forests. So far this year, wildfires have burned more than 7.3 million hectares, more than double the ten-year average for this time of the year. 'What we would hope is that people would take these wildfire seasons as a sign that things are not right, and that indeed projections and predictions of scientists are coming to pass. They were accurate,' says Ness. And now, scientists warn if the trend continue, the planet will continue to burn even hotter and help spread wildfires.
