Charcoal records reveal 'unprecedented' wildfires in tropical peatlands during 20th century
Why it matters: Peat fires unleash carbon and toxic smoke, worsening climate change and health risks.
- Researchers analyzed charcoal records from Southeast Asian peat swamps, finding a ten‑fold rise in fire frequency after 1900 (per the study).
- Tropical peatlands acted as a hidden carbon bomb, emitting billions of tonnes of CO₂ when they burned, amplifying global warming.
- Public health officials warn that the smoke plume can worsen respiratory diseases for millions, linking fire spikes to hospital admissions.
A new Global Change Biology study shows that 20th‑century wildfires in tropical peatlands surged to levels never seen in the past 2,000 years, driven by land‑use change and climate warming. The unprecedented burning releases massive carbon and smoke, threatening regional air quality and accelerating climate feedbacks.
