GHGs Impact Wildfire Outbreaks Regionally

• In a first-of-its-kind study, scientists have assessed the influence of human activities on extreme fire weather risk, and found that greenhouse gas (GHG) emissions and air pollution have distinct regional impacts on wildfire outbreaks.
• The research analysed the climate under various combinations of human influences since 1920, isolating individual effects and their impacts on extreme fire weather risk.

Key Findings

• According to the researchers, heat-trapping GHG emissions are the dominant contributors to temperature increases around the globe.
• By 2005, the emissions raised the risk of extreme fire weather by 20% from preindustrial levels in western and eastern North America, the Mediterranean, Southeast ....
