Himalayan forest fires driven by rising temperatures, not just human activity, study finds

A new study from the Western Himalayas shows that rising temperatures are the strongest driver of forest fires in the region, even more than human activity. Researchers analyzed 39 variables across 18,000 fire locations over ten years and found that every one degree Celsius rise in mean summer temperatures led to roughly 128 additional fire incidents. The study highlights that while most fires are started by people, hotter and drier conditions are what allow them to spread and become severe. This has direct implications for carbon storage in Himalayan forests, which hold an estimated 3.2 billion tonnes of carbon. As temperatures climb, the risk of losing that stored carbon to fire increases, creating a feedback loop that accelerates climate change. The findings underscore the need for fire management strategies that account for rising temperatures, not just human behavior, including controlled burns and better monitoring of fire lines.
