Although scientists studying the greenhouse effect have not paid much attention so far, soot that blackens the chimneys and exhaust pipes of vehicles can be one of the main causes of atmospheric warming, caused between 15 and 30% of global warming. At least researchers from the University of California in Los Angeles have reached this conclusion. Coal is mainly made up of carbon.

90% of emissions to the atmosphere occur in the combustion of fossil fuels, mainly diesel, kerosene and natural gas, as well as in the combustion of wood and other types of biomass. According to the results obtained by the simulation model called GATOR-GCMM, pure soot particles, five days after their entry into the atmosphere, join the mixtures of dust, sea foam, sulphates and other substances. And as is known, carbon-containing mixtures absorb solar radiation and contribute to the warming of the atmosphere and therefore the earth.
