Overview

• Up to 70% of California was covered in wildfire smoke during parts of 2020 and 2021.
• Researchers found that smoke alters light, temperature, and oxygen levels in lakes, affecting photosynthesis and respiration.
• The extent of wildfires in California has increased fivefold since the 1970s, leading to more frequent and intense smoke coverage.
• The study highlights the need to view wildfire smoke as a recurring seasonal phenomenon rather than isolated events.
• Further research is necessary to understand the long-term ecological impacts of wildfire smoke on lake ecosystems.
