How does black carbon affect the climate
WebJun 21, 2024 · A study in last week’s Nature Climate Change is the latest to illustrate the point. The research suggests that rising CO2 levels may cause an increase in extreme weather and climate events ... 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.
