The Exploring Atmospheric Dust and Climate activities were designed to support outreach efforts for the NSF-funded research project DUST PIRE: Dust stimulated draw-down of atmospheric CO2 as a trigger for Northern Hemisphere Glaciation. The project represents a multi-year, international collaboration between scientists across multiple disciplines, each investigating a unique aspect of the connection between Earth’s climate and atmospheric dust.
