Recent satellite data indicates a significant slowdown in the loss of tropical rainforests globally, with 2025 marking a decrease in deforestation rates compared to the previous year. However, experts warn that the anticipated arrival of the El Niño weather pattern later this year could jeopardise these gains, raising concerns about the potential for increased forest fires.
A Promising Decline in Deforestation
According to a report by the World Resources Institute and the University of Maryland, approximately 43,000 square kilometres of old-growth tropical forests were lost worldwide in 2025—an area roughly equivalent to Denmark. This figure represents a 36% reduction compared to the record losses experienced in 2024. While the decline is encouraging, scientists caution that the current rate of forest loss remains alarmingly high, especially when compared to data from a decade ago.
The easing of deforestation rates is attributed, in part, to the cessation of the unprecedented wildfires that ravaged many regions in 2024. This change can be linked to the cooler La Niña conditions that prevailed last year, as opposed to the warmer El Niño that is predicted to arrive soon. Furthermore, enhanced protective measures in countries like Brazil, Colombia, and Malaysia have contributed to this positive trend.
Elizabeth Goldman, co-director of Global Forest Watch at the World Resources Institute, expressed optimism about the findings. “It’s incredibly encouraging to see the decline in 2025,” she remarked, emphasising that strong political will can yield tangible results for forest conservation.
Brazil’s Role in Forest Conservation
Brazil, home to the Amazon rainforest—the largest in the world—has been a focal point in the fight against deforestation. The nation has enforced stricter environmental policies and improved law enforcement, leading to a notable decrease in forest loss. In 2025, an estimated 5,700 square kilometres of old-growth tropical forests were lost in Brazil, marking the lowest rate since monitoring began in 2002.
Tropical rainforests are vital ecosystems, hosting millions of species and acting as significant carbon sinks that help mitigate climate change. However, decades of land clearing for agriculture and logging have placed these essential habitats under immense pressure. Climate change further exacerbates the problem, creating conditions ripe for the spread of wildfires.
The Threat of El Niño and Climate Change
Despite the positive trends observed in 2025, the looming threat of the El Niño weather phenomenon poses a significant risk to forests worldwide. Predictions suggest that this climatic shift could lead to hotter and drier conditions, increasing the likelihood and intensity of wildfires.
Rod Taylor, global director for forest and nature conservation at the World Resources Institute, highlighted the challenges that forests face in adapting to these new climate realities. “Forests are well equipped to cope with normal climate,” he stated, “but with these new intense fires and droughts, we really have to think about how to make forests more resilient.”
Professor Matthew Hansen from the University of Maryland echoed these concerns, stating, “Climate change and land clearing have shortened the fuse on global forest fires. Without urgent action to manage fire more effectively, we risk pushing the world’s most important forests past recovery.”
A Broader Context: Europe’s Climate Struggles
The risks associated with climate change are not confined to tropical regions. A recent report from the EU’s Copernicus climate service revealed that Europe experienced intense heatwaves, wildfires, and droughts last year. With 95% of the continent recording above-average temperatures, over 10,000 square kilometres of land were consumed by flames—an area larger than Cyprus.
Even traditionally cooler areas, such as the Alps, have not been spared. Alpine glaciers continue to lose ice, and temperatures in the Arctic Circle soared to 30°C in July. However, it is worth noting that nearly half of Europe’s electricity now comes from renewable sources, offering a glimmer of hope amid the broader climate crisis.
Why it Matters
The recent slowdown in global forest loss is a hopeful development, showing that concerted efforts can lead to tangible change. Nevertheless, the anticipated impact of El Niño and the ongoing challenges posed by climate change underscore the fragility of these gains. As we move forward, it is crucial to bolster protections for our forests, which play an essential role in sustaining biodiversity and combating climate change. The stakes are high, and without immediate action, we risk losing some of the planet’s most vital ecosystems forever.
