A long-term shift in the tropical Pacific Ocean has had contrasting effects on wildfire activity in different parts of the world. In the U.S. Southwest, this shift has increased fire-prone conditions by about 22%, while in eastern Australia, it has eased them by around 19%. According to a study published in Nature Communications, these findings are based on nearly four decades of wildfire and climate data from 1984 to 2022. Researchers analyzed satellite observations, climate records, and climate model simulations to understand how the uneven warming of the tropical Pacific has influenced wildfire risk in two of the world's most fire-prone regions. The study highlights that while human-driven climate change remains the main driver of increasing atmospheric dryness, the Pacific Ocean pattern can either amplify or dampen its impact.
