5 Key Takeaways

• 1

  The Amazon canopy study during the 2023-2024 El Niño found a 122% increase in sesquiterpene levels due to extreme drought.

• 2

  Sesquiterpene alcohols were detected in the wet season after peak drought, indicating persistent stress-related metabolic changes.

• 3

  The study highlights a shift toward lower-volatility and more reactive compounds in the atmosphere due to severe drought.

• 4

  Researchers used advanced sampling techniques to track isoprene, monoterpenoids, and sesquiterpenoids across four periods.

• 5

  Climate models predict increased frequency and intensity of El Niño events, potentially making these emissions a permanent feature.
