What is black carbon, and what does it mean for climate change?
Web6 days ago · Made up of pure carbon, black carbon is a major component of fine particulate matter (PM2.5) and soot. It is often created from the incomplete combustion of fossil fuels or biological material, such as from forest fires. In Antarctica, black carbon is usually emitted from sources like ships, aircraft or power generators.
What is Black Carbon? - Center for Climate and Energy Solutions
WebBlack Carbon (BC) has recently emerged as a major contributor to global climate change, possibly second only to CO 2 as the main driver of change. BC particles strongly absorb sunlight and give soot its black color. BC is produced both naturally and by human activities as a result of the incomplete combustion of fossil fuels, biofuels, and biomass.

WebBlack carbon is dark in color and warms the Earth in two ways: When it’s in the air, the particles absorb sunlight and generate heat in the atmosphere. This can affect cloud formation and rain patterns. When it covers snow and ice, the sun’s radiation is absorbed instead of being reflected back into the atmosphere.
