Global Surge in Forest Fire CO2 Emissions Threatens Climate Goals

A comprehensive study conducted by the University of East Anglia, published in *Science*, highlights the alarming surge in carbon dioxide emissions from forest fires. **Since 2001, CO2 emissions have increased by 60% globally, with nearly triple increases in susceptible boreal forests.** The research grouped regions into 'pyromes', unveiling factors such as fire-favourable weather and increased forest growth as primary drivers. The shift of emissions from tropical to extratropical forests signifies the influence of rapid warming, doubling the global average in northern latitudes. This escalation threatens forest carbon storage, crucial for combatting climate change. While the extent and severity of forest fires have increased, the misconception of reduced wildfire impact due to lesser tropical savannah fires is debunked. **Machine learning played a crucial role in this research, grouping ecoregions and isolating climate effects from land use.** The work underscores the necessity for proactive fire management and highlights priority areas needing strategic response. With contributions from notable international researchers and funding from prominent agencies like NERC and the European Commission, the study calls for immediate action to protect vital ecosystems and achieve global climate targets.
