What happened
A recent study has developed a machine learning framework to project the impact of climate change on wildfire emissions and health outcomes. It predicts a 23% increase in carbon emissions from wildfires between 2010-2014 and 2095-2099 under the Shared Socioeconomic Pathway (SSP) 2-4.5 scenario. The research estimates that premature deaths from wildfire smoke could rise to 1.4 million annually by the end of the century, with Africa facing an 11-fold increase in fire-related deaths. In contrast, Europe and the U.S. are projected to see a 1-2 fold increase. The study emphasizes that the health burden will become more evenly distributed across nations, necessitating coordinated global responses to mitigate these impacts.
