Recent satellite observations indicate a significant slowdown in global tropical forest loss, primarily attributed to enhanced conservation initiatives in countries like Brazil. In 2025, approximately 43,000 square kilometres (17,000 square miles) of old-growth tropical forests were lost worldwide, a reduction of nearly one-third compared to the record losses of the previous year. However, experts caution that the threat posed by climate change and the impending El Niño weather pattern could jeopardise this progress, potentially exacerbating forest fires and further endangering these vital ecosystems.
Deforestation Rates Drop Significantly
The latest figures from the World Resources Institute (WRI) and the University of Maryland reveal that tropical forest loss decreased by 36% in 2025. This marks a notable improvement, though it remains critical to underscore that the rate of deforestation is still alarmingly higher than it was a decade ago. Scientists note that while the data reflects a positive trend, the timing of satellite observations may introduce some uncertainty, particularly in capturing late-year losses.
The decline in deforestation rates can be linked to a combination of factors, including the influence of cooler La Niña conditions in 2025, which mitigated the unprecedented fires experienced in 2024. Enhanced environmental policies and stricter law enforcement in Brazil, Colombia, and Malaysia have also played a pivotal role in curbing deforestation.
Elizabeth Goldman, co-director of Global Forest Watch at the WRI, expressed optimism regarding the data. “It’s incredibly encouraging to see the decline in 2025,” she stated. “This highlights how political will and leadership focused on forest preservation can yield tangible results.”
Brazil’s Conservation Successes
Brazil, the custodian of the world’s largest rainforest, has been at the forefront of these conservation efforts. Researchers report that, excluding fire-related losses, roughly 5,700 square kilometres (2,200 square miles) of old-growth tropical forest were lost in Brazil last year—the lowest figure since tracking began in 2002. This achievement is a testament to the effectiveness of stringent environmental legislation and proactive measures to safeguard forest resources.
Tropical rainforests are invaluable not only for their biodiversity, hosting millions of species, but also for their critical role in carbon sequestration, which helps regulate global temperatures. Despite these benefits, decades of deforestation driven by agriculture, logging, and climate change have put these ecosystems under increasing threat.
The Looming Threat of El Niño
Looking ahead, scientists are concerned that the anticipated return of the El Niño weather pattern could pose a new challenge to global forest preservation. This phenomenon, characterised by warmer ocean temperatures, has the potential to increase both the intensity and frequency of forest fires. As Rod Taylor, global director for forest and nature conservation at the WRI, observed, “Forests are naturally resilient to typical climate variations, but we must now consider how to fortify them against extreme events like intense fires and prolonged droughts.”
Prof. Matthew Hansen from the University of Maryland echoed these concerns, stating, “Climate change and land clearing have effectively shortened the fuse on global forest fires. Without immediate action to enhance fire management strategies, we risk pushing the world’s most vital forests past their point of recovery.”
Climate Change and European Forest Fires
This year also brings lessons from Europe, where the Copernicus Climate Service reported that climate change has intensified heatwaves, droughts, and wildfires across the continent. In 2025, over 10,000 square kilometres (4,000 square miles) were consumed by fires, exacerbated by record-high temperatures that affected at least 95% of Europe. The Mediterranean Sea experienced particularly severe warming, contributing to ongoing environmental challenges.
Despite these alarming trends, there is a glimmer of hope, as nearly half of Europe’s electricity now comes from renewable sources such as wind, solar, and hydropower, indicating a commitment to mitigating climate change.
Why it Matters
The recent decline in global forest loss signifies a hopeful turning point in conservation efforts, demonstrating that effective governance and robust policies can lead to tangible environmental improvements. However, the spectre of climate change and the impending El Niño emphasise the fragility of this progress, underscoring the urgent need for sustained action and innovative strategies to safeguard our remaining forests. As the world grapples with these interconnected challenges, the resilience of our planet’s ecosystems hangs in the balance, making immediate and decisive action more critical than ever.
