Recent satellite analyses reveal a notable decline in global tropical forest loss, largely attributed to enhanced protective measures in key regions like Brazil. However, experts caution that the imminent arrival of El Niño and the ongoing impacts of climate change could jeopardise this progress.
Decline in Deforestation Rates
The latest data indicates that approximately 43,000 square kilometres of old-growth tropical forests were lost worldwide in 2025, which is roughly equivalent to the size of Denmark. This figure represents a significant reduction of 36% compared to the record losses observed in 2024. Despite this positive trend, scientists stress that the rate of deforestation remains alarmingly high compared to a decade ago.
The reduction in forest loss is partially credited to improved forest management and law enforcement measures in countries such as Brazil, Colombia, and Malaysia. Elizabeth Goldman, co-director of Global Forest Watch at the World Resources Institute, expressed optimism over the findings. “It’s incredibly encouraging to see the decline in 2025,” she remarked, emphasising the importance of political will in achieving tangible results.
Brazil’s Role in Forest Protection
In Brazil, home to the world’s largest rainforest, stronger environmental policies have been instrumental in curbing deforestation. The nation recorded the lowest loss of old-growth tropical forests since 2002, with an estimated 5,700 square kilometres vanishing last year, excluding losses due to fires. This achievement underscores the potential for effective governance and policy implementation in protecting vital ecosystems.
Tropical rainforests play a crucial role in regulating the Earth’s climate by absorbing significant amounts of carbon dioxide. However, they face mounting pressures from agriculture, logging, and climate change, which exacerbates the risk of wildfires. Experts like Rod Taylor, global director for forest and nature conservation at the World Resources Institute, highlight the need for strategies to bolster forest resilience against the growing threat of climate-induced fires.
The Impending Threat of El Niño
While the decline in forest loss is a positive development, the upcoming El Niño weather pattern poses a significant risk. Climate change, coupled with the warmer conditions associated with El Niño, could lead to increased frequency and intensity of forest fires. Professor Matthew Hansen from the University of Maryland warns, “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.”
Researchers are closely monitoring this situation, recognising the urgency of addressing the dual threats posed by climate fluctuations and anthropogenic activities.
A Broader Context: Climate Change Impact
The implications of climate change extend beyond forest loss, as demonstrated by a recent report from the EU’s Copernicus climate service. This report highlights the profound impacts of climate change across Europe, where nearly all regions experienced above-average temperatures last year, leading to extensive wildfires that consumed over 10,000 square kilometres of land.
The Mediterranean Sea recorded its highest surface temperatures on record, further illustrating the pervasive effects of climate change. Yet, amidst these challenges, there is a glimmer of hope, with nearly half of Europe’s electricity now generated from renewable sources such as wind, solar, and hydropower.
Why it Matters
The slowing rate of global forest loss is a testament to the potential impact of effective environmental policies and international cooperation. However, the looming threat of El Niño and climate change could reverse these gains if not addressed promptly. As the world grapples with the urgent need for sustainable practices, the fate of our forests remains in a precarious balance. Protecting these vital ecosystems is not just an environmental issue; it is a crucial step toward safeguarding the planet’s climate and biodiversity for future generations.
