At this talk, Dr. Kostas Tsigaridis will share insights from his research on how different high-altitude events shape stratospheric aerosols and influence the broader Earth system. He will discuss the impacts of volcanic eruptions, large-scale fires, and rocket launches on atmospheric chemistry and circulation, highlighting how these processes interact with the protective ozone layer. This presentation will offer a high-level overview of the links between atmospheric dynamics and global environmental change.
