Recent satellite observations indicate a noteworthy deceleration in the global loss of tropical rainforests, primarily attributed to Brazil’s intensified efforts to combat deforestation. In 2025, approximately 43,000 square kilometres of old-growth tropical forests disappeared worldwide—a reduction of 36% compared to the unprecedented losses recorded in 2024. However, scientists caution that the fight to preserve these vital ecosystems remains precarious, particularly with the impending El Niño weather phenomenon potentially exacerbating fire risks.
Significant Reduction in Forest Loss
The data, compiled by the World Resources Institute and the University of Maryland, reveals a decline in tropical forest loss that is about one-third lower than the record losses of the previous year. Researchers express confidence in the trend, despite some uncertainty surrounding the precise timing of losses detected by satellites. Notably, the reduction in forest loss correlates with a decrease in the extreme wildfires that ravaged large areas in 2024, largely due to the cooler La Niña conditions that prevailed.
Elizabeth Goldman, co-director of Global Forest Watch at the World Resources Institute, remarked, “It’s incredibly encouraging to see the decline in 2025. It highlights how when we have political will and leaders committed to forest preservation, we can observe tangible improvements in the data.”
Brazil’s Environmental Policies Show Results
Brazil, home to the world’s largest rainforest, has seen positive outcomes from its robust environmental policies and law enforcement efforts aimed at curbing deforestation. The country reported an estimated loss of 5,700 square kilometres of old-growth tropical forests in 2025, marking the lowest figure since records began in 2002. This achievement underscores the impact of strong governance and strategic interventions in protecting vital ecosystems.
Tropical rainforests play a crucial role in sequestering carbon dioxide, helping to mitigate climate change. Yet, these irreplaceable habitats have faced relentless pressure from agricultural expansion, logging, and climate change-induced conditions that facilitate the spread of wildfires.
The Threat of El Niño and Climate Change
Despite the positive trends observed, the future remains uncertain. Researchers are concerned that the dual challenges of climate change and the anticipated warmer conditions brought on by El Niño could lead to an uptick in forest fires. “Climate change and land clearing have shortened the fuse on global forest fires,” cautioned Professor Matthew Hansen from the University of Maryland. He emphasised the urgent need for effective fire management strategies to safeguard the world’s most essential forests.
The European Union’s Copernicus Climate Service recently reported on the escalating effects of climate change, highlighting that 95% of Europe experienced above-average annual temperatures last year, culminating in extensive wildfires that consumed more than 10,000 square kilometres. These alarming trends serve as a reminder of the broader implications of climate change on global ecosystems.
The Path Ahead: Urgent Action Required
World leaders have pledged to “halt and reverse” deforestation by 2030, a goal outlined during the COP26 climate summit in Glasgow. However, the current trajectory suggests that significant challenges remain in achieving this ambitious target. As ecosystems face increased pressures from climate change and human activity, enhancing their resilience against such threats will be critical.
Rod Taylor, global director for forest and nature conservation at the World Resources Institute, noted, “Forests are well equipped to cope with normal climate. With these new intense fires and droughts, we really have to think about how to make forests more resilient and proof them against climate and fire.”
Why it Matters
The recent data on forest loss presents a mixed picture; while there is a hopeful decline in deforestation rates, the looming threat of climate change and El Niño poses a significant risk to the progress made. The health of tropical rainforests is paramount not only for biodiversity but also for global climate stability. As we navigate these complex challenges, the imperative for coordinated international action and robust local governance becomes ever more pressing to ensure the preservation of these irreplaceable ecosystems for future generations.
