Recent satellite observations indicate a significant reduction in global tropical forest loss in 2025, demonstrating the impact of enhanced environmental policies and a temporary reprieve from extreme weather conditions. However, the looming presence of the El Niño climate pattern raises concerns about potential setbacks in preserving these vital ecosystems.
A Notable Decrease in Deforestation
New analysis from the World Resources Institute and the University of Maryland reveals that approximately 43,000 square kilometres (17,000 square miles) of old-growth tropical forests were lost globally in 2025, a decline of 36% compared to the previous year. This reduction is equivalent to the size of Denmark and represents a significant decrease from the record losses experienced in 2024. While this trend is encouraging, experts caution that tropical forests continue to vanish at alarming rates compared to a decade ago.
The data, while indicative of a positive trajectory, carries some uncertainty. Satellite technology may lag in detecting late-year losses until the subsequent year, yet scientists remain confident in the overall downward trend. The combination of fewer severe fires experienced in 2024, attributed to cooler La Niña conditions, alongside increased forest protection efforts in countries like Brazil, Colombia, and Malaysia, has contributed to this encouraging shift.
Brazil’s Environmental Policies Show Results
In Brazil, home to the Amazon—the largest rainforest on the planet—stronger environmental regulations and more rigorous enforcement have played an essential role in curbing deforestation. Excluding fire-related losses, the country saw an estimated 5,700 square kilometres (2,200 square miles) of old-growth forest disappear last year, marking the lowest figure since tracking began in 2002. Elizabeth Goldman, co-director of Global Forest Watch, remarked, “It’s incredibly encouraging to see the decline in 2025. It highlights how when we have political will and leaders who prioritise forest preservation, we can achieve tangible results.”
Despite this progress, the ongoing threat of climate change and human activities such as agriculture and logging continue to undermine tropical forests. These ecosystems, crucial for carbon dioxide absorption and biodiversity, are facing unprecedented pressures that could hinder their recovery.
The Rising Threat of El Niño
Looking ahead, scientists express concern that the return of the El Niño phenomenon later this year could exacerbate forest fire risks. This climate pattern, coupled with ongoing climate change, may create conditions conducive to increased fire incidence and severity. Professor Matthew Hansen from the University of Maryland warned, “Climate change and land clearing have shortened the fuse on global forest fires. Without urgent action to manage fire effectively, we risk pushing the world’s most vital forests past the point of recovery.”
This warning aligns with a recent report from the EU’s Copernicus climate service, which highlighted the escalating impact of climate change on weather patterns across Europe. The continent, already the fastest-warming in the world, experienced widespread heatwaves, droughts, and extensive wildfires in the previous year. More than 10,000 square kilometres (4,000 square miles) burned across Europe, underscoring the urgent need for comprehensive climate action.
Progress Amid Challenges
Despite the daunting challenges posed by climate change, there are signs of progress. Nearly half of Europe’s electricity now derives from renewable sources, including wind, solar, and hydropower. This shift represents a crucial step towards combating climate change and mitigating its effects on forests and ecosystems globally.
Why it Matters
The recent slowdown in tropical forest loss is a beacon of hope in the fight against climate change. It underscores the significance of political commitment and effective policy implementation in environmental conservation. However, the multifaceted threats posed by climate change, particularly the anticipated resurgence of El Niño, highlight the fragility of these gains. As the world grapples with these challenges, proactive measures and global cooperation will be essential in preserving our planet’s invaluable forests for future generations.
