NASA | Scientists Link Earlier Melting Of Snow To Dark Aerosols

NASA scientists highlight the significant impact of aerosols on snow and climate in the northern hemisphere. Aerosols from wildfires and fossil fuels darken snow, increasing sunlight absorption and accelerating melting. This 'snow darkening effect' leads to earlier snowmelt and warmer temperatures. Researchers used climate models to study the impact of dust, black carbon, and organic carbon on snowpack, revealing reduced snow amounts and potential climate changes. The accumulation of aerosols alters atmospheric particles, potentially exacerbating climate change.
