New research shows that relatively small volcanic eruptions can increase aerosol particles in the atmosphere, temporarily mitigating the global warming caused by greenhouse gases. The impact of such smaller eruptions has been underestimated in climate models, the researchers say, and helps to account for a discrepancy between those models and the actual temperatures observed over the last 15 years.
The Program in Atmospheres, Oceans, and Climate oversees a broad program of research and education directed at understanding the Earth in all its aspects - physical, chemical and biological - and how Earth has evolved over time to its present state and its likely future trajectory.
We make use of observations, theory and models and also place our studies in the context of planetary systems. Many of the most important discoveries in our science, such as chaos, the chemistry of the ozone hole and the physics of hurricanes were made by PAOC scientists.
