Rapid summer Russian Arctic sea-ice loss enhances the risk of recent Eastern Siberian wildfires

B. Luo, D. Luo, et al.

Discover how recent wildfires in eastern Siberia are closely linked to warming trends and sea-ice decline in the Russian Arctic. This groundbreaking research by Binhe Luo and colleagues reveals that 79% of the increasing summer vapor pressure deficit is attributed to these climatic changes, while internal atmospheric variability contributes 21%. Join us in exploring the critical connections between climate change and wildfires.

Abstract

Recent increases in eastern Siberian wildfires are investigated, attributing 79% of the increase in summer vapor pressure deficit (VPD) to background eastern Siberian Arctic warming (BAW) related to summer Russian Arctic sea-ice decline. The remaining 21% is linked to internal atmospheric variability from changes in Siberian blocking events. These changes in blocking events, influenced by BAW, result in more persistent, widespread, and intense high-latitude warming and VPD, thus contributing to increased wildfires.
