Unprecedented levels of forest fire activity and severity have been observed globally. This study shows a strong correlation between fire activity in all global forest biomes and atmospheric water demand, specifically maximum daily vapor pressure deficit (VPD). Climate change projections indicate widespread increases in fire risk, with significant implications for carbon loss (e.g., Amazon rainforest) and human health (e.g., South Asia, East Africa) due to wildfire smoke.
