C. Black carbon emissions come from several sources and affect the earth’s temperature. Nội dung bài nghe
Hi everyone. Thanks for offering me the opportunity to talk about black carbon.
Black carbon, also known as soot, consists of tiny pieces of black dust. It mainly comes
from forest fires and the burning of fossil fuels and crop waste. We now know that it
plays a much bigger role in global warming than previously thought. Let me first talk
more about the burning of crop waste. Do you know why farmers do that? Well, they
believe that burning is the best way to clear land and prepare it for new crops. However,
these huge fires are the world's biggest source of soot. In addition, burning crop waste is
bad for the soil because it kills the useful organisms living in it. But how long does black
carbon stay in the atmosphere? Actually, it only lasts for a few days or weeks after it is
released. However, its effect on the earth's temperature is more powerful than that of
carbon dioxide. Black carbon traps more sunlight and sends it back into the air as heat. In

Black carbon is a common air pollutant found in many urban areas around the world.
Black carbon primarily comes from the incomplete combustion of fossil fuels, biomass,
and biofuels. Sources of black carbon emissions can include transportation (e.g., cars,
trucks, buses), industrial processes, and residential cooking and heating (e.g., wood- burning stoves).
