Black carbon in soot is an efficient absorbing agent of solar irradiation that is preferentially emitted in the tropics and can form atmospheric brown clouds in mixture with other aerosols. These factors combine to make black carbon emissions the second most important contribution to anthropogenic climate warming, after carbon dioxide emissions. 
Warming influenced by the ratio of black carbon to sulphate and the black-carbon source
Black-carbon aerosols absorb solar radiation and are thought to be a significant source of global warming. Surface and aircraft measurements of aerosol plumes in China suggest that solar absorption
Isotope-based source apportionment of black carbon aerosols in the Eurasian Arctic
Aerosols change the Earth's energy balance. Black carbon (BC) aerosols are a product of incomplete combustion of fossil fuels and biomass burning and cause a net warming through aerosol radiation i
Brownness of organics in aerosols from biomass burning linked to their black carbon content
Atmospheric aerosols can exert an important influence on Earth’s climate. Combustion chamber experiments reveal that the absorption properties of brown carbon aerosols from biomass burning are linked

Abstract. In order to determine the wavelength dependence of fine ( The AAE values were compared to stable and radiocarbon isotopic measurements of the 12-h aerosol samples to determine the sources
Aging of Atmospheric Brown Carbon Aerosol
Emitted by numerous primary sources and formed by secondary sources, atmospheric brown carbon (BrC) aerosol is chemically complex. As BrC aerosol ages in the atmosphere via a variety of chemical an...
Aging of atmospheric aerosols and the role of iron in catalyzing brown carbon formation
Iron in mineral dust can catalyze reactions with atmospheric organics that lead to the formation of brown carbon (BrC) that impact the climate in a number of ways.
Anthropogenic influence on climate through changes in aerosol emissions from air pollution and land use change
Particulate matter suspended in air (i.e. aerosol particles) exerts a substantial influence on the climate of our planet and is responsible for causing severe public health problems in many regions
Advances in the Study of Black Carbon Effects on Climate
Abstract Black carbon (BC) aerosols can strongly absorb solar radiation in very broad spectral wavebands, from the visible to the infrared. As a potential factor contributing to global warming, BC
Atmospheric black carbon and warming effects influenced by the source and absorption enhancement in central Europe
Abstract. Particles containing black carbon (BC), a strong absorbing substance, exert a rather uncertain direct and indirect radiative forcing in the atmosphere. To investigate the mass concentration
The Arctic Ice Melting Caused by Black Carbon from an Environmental Risk Analysis Perspective
The purpose with this essay is to highlight the environmental risk that black-carbon aerosols represent to the ice melting in the Arctic. When the ice melting in the Arctic and other climate-relate

The Parasol Effect on Climate
By backscattering solar radiation, aerosol particles and clouds exert a cooling (parasol) effect on climate, dampening Earth's warming by the greenhouse gases (GHG) (T. L. Anderson et al. , “Climate
Can reducing black carbon emissions counteract global warming?
TLDR
Addressing black carbon emissions is a promising way to reduce climatic interference primarily for nations that have not yet agreed to address greenhouse gas emissions and provides the potential for a parallel climate agreement.

20th-Century Industrial Black Carbon Emissions Altered Arctic Climate Forcing
TLDR
At its maximum from 1906 to 1910, estimated surface climate forcing in early summer from BC in Arctic snow was about 3 watts per square meter, which is eight times the typical preindustrial forcing value.
Strong present-day aerosol cooling implies a hot future
TLDR
Strong aerosol cooling in the past and present would imply that future global warming may proceed at or even above the upper extreme of the range projected by the Intergovernmental Panel on Climate Change.
Global atmospheric black carbon inferred from AERONET
TLDR
It is found that the amount of BC in current climatologies must be increased by a factor of 2–4 to yield best agreement with AERONET, in the approximation in which BC is externally mixed with other aerosols.
