Rapid Permafrost Thaw Predicted to Intensify Northern Wildfires

New climate models show a dramatic increase in wildfire activity in Arctic and Subarctic regions due to accelerated permafrost thawing.

An international study indicates that global warming will accelerate permafrost thawing, leading to more intense wildfires in northern Canada and Siberia.
Recent climate models have integrated the interactions between soil water, permafrost, and wildfires, providing a comprehensive view of future risks.
By the mid to late 21st century, extensive permafrost thawing will cause a sharp drop in soil moisture, higher surface temperatures, and drier conditions, all of which contribute to wildfire intensification.
Increasing atmospheric CO2 levels will boost vegetation biomass, providing additional fuel for wildfires in high latitude areas.
Wildfires in permafrost regions release significant amounts of carbon dioxide and methane, further accelerating global warming and creating a feedback loop that exacerbates climate change.
