Ammonia emissions from agricultural fertilizers will likely double by the year 2100. When ammonia reaches the upper atmosphere through convection, it significantly increases aerosol formation, seeding clouds and affecting global climate. In PNAS: https://ow.ly/I9jY50XlMiU

Human-made ammonia boosts high-altitude particle and cloud formation, affecting climate.
Our study investigates how ammonia (NH₃) emissions from human activities—mainly agriculture—affect aerosol formation high in the atmosphere, in the upper troposphere and lower stratosphere. Using the ...

Isoprene Aerosol Growth in the Upper Troposphere: Application of the Diagonal Volatility Basis Set to CLOUD Chamber Measurements
Isoprene oxygenated organic molecules (IP-OOM) can nucleate new particles in the upper troposphere. These particles may grow into cloud condensation nuclei and influence the clouds and climate. Howeve...
