Sea spray Complex chemistry with big effects on climate

The video explores the role of marine aerosols in climate change, focusing on research led by atmospheric chemist Kimberly Prather. It highlights the complexity of aerosols, their impact on clouds and climate, and the laboratory experiments designed to replicate ocean conditions. The research aims to improve climate models by understanding the chemical composition of sea spray aerosols. New discoveries challenge existing hypotheses, emphasizing the need to understand sea spray chemistry to comprehend climate change.

What are marine aerosols primarily composed of?

• Only salt
