As an important light-absorbing aerosol, black carbon (BC) can affect the energy balance of the earth-atmosphere system via direct and indirect radiative forcing. When BC deposits on snow and ice, it can trigger BC-snow/ice ...

Black carbon or BC is formed through the incomplete combustion of fossil fuels, biofuel, and biomass, and is emitted in both anthropogenic and naturally occurring soot. Black carbon warms the planet by absorbing heat in the atmosphere and by reducing albedo, the ability to reflect sunlight, when deposited on snow and ice. Black carbon stays in the atmosphere for only several days to weeks, whereas CO2 has an atmospheric lifetime of more than 100 years.
