Presentation description

Wildfire frequency and severity, particularly in North America, have increased substantially over the last decade due to human-caused climate change. With increasing fire activity, an associated increase in fire-caused atmospheric and climatological phenomena will likely occur, including fire-initiated thunderstorms or 'Pyrocumulonimbus (PyroCb) clouds'. These thunderstorms can inject smoke and aerosols into the upper troposphere and lower stratosphere, significantly impacting air quality
