Drought and wildfire weaken Earth's carbon sinks, study finds

Study finds compound drought-fire events decouple carbon and water efficiency

Huipeng Xi and Qunming Wang's analysis of satellite data from 2001 to 2022 identifies 72,088 meteorological and 108,373 hydrological compound drought-fire events globally. The research reveals that vegetation hit by these compound events becomes markedly more sensitive to rainfall while simultaneously losing efficiency at converting water into carbon gain—a decoupling that signals ecosystem fragility.

“Our findings reveal a critical vulnerability: after compound drought–fire events, ecosystems become more dependent on rainfall but less efficient at converting water into carbon gain.”
