Caution: black carbon!

I wandered around the nasa site in search of interesting photos and came across the notion of black carbon that was unknown to me until now. Not having worked any sensible information in my native language, I decided to publish a brief overview of the term.


Black carbon, commonly known as soot, is formed by incomplete combustion of fossil fuels, biofuels, and biomass, and is released during both man-made and natural cases of carbon pollution. Black carbon heats the planet, absorbing heat in the atmosphere and reducing the albedo, the ability to reflect sunlight when it settles on snow and ice. Black carbon remains in the atmosphere from several days to weeks, while carbon dioxide is able to remain in it for more than 100 years.

As interest in Earth’s climate change is heating up, a tiny dark particle is in the spotlight.

Black carbon is a powerful climate-forcing substance, it is estimated to be the second largest contributor to global warming after carbon dioxide. Because black carbon remains in the atmosphere only for a few weeks, reducing its spread may be the fastest way to slow climate change in the near future.

Black carbon is found all over the world, but its presence and impact is particularly strong in Asia. The high levels of Tibetan Plateau's black carbon probably affect the temperature of the region, the clouds and the monsoon season.

more to say: IPCC estimates that black carbon has as much as 55% of the impact of CO2 on the climate and more than the impact of other greenhouse gases such as CH4, chlorofluorocarbons, N2O, or tropospheric ozone.
In some areas, such as the Himalayas, the effects of black carbon on melting snow and glaciers may be equal to CO2. Black carbon emissions also significantly contribute to the melting of Arctic ice, which is important because nothing in climate is plotted more precisely as the 0 ° C boundary that separates frozen water from liquid — bright, reflective snow and ice from a dark, heat-absorbing ocean. Therefore, reducing such emissions can be the most effective way to mitigate the warming of the Arctic, which is known.

be careful: do not confuse soot or black carbon with Carbon Black (carbon black) [CAS NO. 1333-86-4], practically pure carbon in the form of colloidal particles, which are formed as a result of incomplete combustion or thermal decomposition of gaseous or liquid hydrocarbons under controlled conditions . Outwardly it is a black, fine granules or powder. Its use for tires, rubber and plastic products, printing inks and coatings, is associated with the physical properties of the surface, the size and structure of particles, electrical conductivity and color. Current global production is about 18 billion pounds per year [8.1 million tons]. About 90% of carbon black is used in rubber production, 9% as a pigment, and the remaining 1% as the main ingredient in hundreds of different products.
Black carbon and soot contain a large amount of dichloromethane- and toluene-extractable substances, and can also show ash content of 50% or more.
