Silent Storms Loud Impact: Thunderstorms Emerge as Major Killer in Tropical Forests
For years, the main threats to tropical forests were seen as drought, heat, rising carbon dioxide, and raging wildfires. But new research reveals that a quieter, often-overlooked culprit may be doing more damage than previously imagined thunderstorms. According to a study published in Ecology Letters on July 1, 2025, these short-lived but intense convective storms could be behind a significant portion of tree deaths across the Amazon.
The study found that convective storms may account for up to 50% of the observed rise in biomass mortality in tropical forests. In some scenarios, the impact could be as low as 12%, or as high as a staggering 118%, depending on various assumptions and data interpretations. The sheer scale of this finding has stunned ecologists, as these storms which span j...
