摘　　要：Wildfires burn approximately 3%-4% of the global land area annually,resulting in massive emissions of greenhouse gases and air pollutants.Over the past two decades,there has been a declining trend in both global burned area and wildfire emissions.This trend is largely attributed to a decrease in wildfire activity in Africa,which accounts for a substantial portion of the total burned area and emissions.However,the northern high-latitude regions of Asia and North America have witnessed substantial interannual variability in wildfire activity,with several severe events occurring in recent years.Climate plays a pivotal role in influencing wildfire activity and has led to more wildfires in high-latitude regions.These wildfires pose significant threats to climate,ecosystems,and human health.Given recent changes in wildfire patterns and their impacts,it is critical to understand the contributors of wildfires,focus on deteriorating high-latitude areas,and address health risks in poorly managed areas tomitigate wildfire effects.
