Atmospheric dust plays a dual role in Earth's climate: it reflects some sunlight back into space while also absorbing and retaining the planet's heat like an insulating blanket. But while dust likely cools the planet overall, that's not the whole story. New UCLA research shows that the heat-trapping effect of airborne desert dust in the atmosphere is about twice as big as previously believed.
