This research examines how atmospheric aerosols influence cloud formation and rainfall, particularly under turbulent conditions. Using a laboratory cloud chamber and computer modeling, the study investigates how particle size and concentration affect droplet growth. The findings aim to improve climate models and weather forecasting in both polluted and clean environments.

This research examined Antarctic soils for microplastics and found contamination near human activity at Scott Base and Cape Evans, but none in the remote McMurdo Dry Valleys. The findings reveal one of the last microplastic-free environments and highlight how clothing choices and human presence influence even Earth’s most pristine ecosystems.

The Arctic is no longer pristine. “Forever chemicals” like OPEs and PFAS are accumulating in wildlife and ecosystems, threatening Inuit food sources. By studying Arctic seabirds as early-warning indicators, this research provides critical evidence to inform regulation and protect vulnerable environments and communities.
