Anthropogenic emissions of fine black carbon (BC) particles, the principal light‐absorbing atmospheric aerosol, have varied during the past century in response to changes of fossil‐fuel utilization, technology developments, and emission controls. We estimate historical trends of fossil‐fuel BC emissions in six regions that represent about two‐thirds of present day emissions and extrapolate these to global emissions from 1875 onward. Qualitative features in these trends show rapid increase in… 

Detecting the influence of fossil fuel and bio-fuel black carbon aerosols on near surface temperature changes

Abstract. Past research has shown that the dominant influence on recent global climate changes is from anthropogenic greenhouse gas increases with implications for future increases in global

Sensitivity of global‐scale climate change attribution results to inclusion of fossil fuel black carbon aerosol

It is likely that greenhouse gas emissions caused most of the global mean warming observed during the 20th century, and that sulphate aerosols counteracted this warming to some extent, by reflecting

20th-Century Industrial Black Carbon Emissions Altered Arctic Climate Forcing

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.

Historical emissions of black and organic carbon aerosol from energy‐related combustion, 1850–2000

We present an emission inventory of primary black carbon (BC) and primary organic carbon (OC) aerosols from fossil fuel and biofuel combustion between 1850 and 2000. We reconstruct fossil fuel

Bounding the role of black carbon in the climate system: A scientific assessment

Black carbon aerosol plays a unique and important role in Earth's climate system. Black carbon is a type of carbonaceous material with a unique combination of physical properties. This assessment

Historical emissions of carbonaceous aerosols from biomass and fossil fuel burning for the period 1870–2000

Historical changes of black carbon (BC) and particulate organic matter (POM) emissions from biomass burning (BB) and fossil fuel (FF) burning are estimated from 1870 to 2000. A bottom‐up inventory

Coupled Aerosol-Chemistry-Climate Twentieth-Century Transient Model Investigation: Trends in Short-Lived Species and Climate Responses

AbstractThe authors simulate transient twentieth-century climate in the Goddard Institute for Space Studies (GISS) GCM, with aerosol and ozone chemistry fully coupled to one another and to climate

A global emission inventory of carbonaceous aerosol from historic records of fossil fuel and biofuel consumption for the period 1860–1997

Country by country emission inventories for carbonaceous aerosol for the period 1860 to 1997 have been constructed on the basis of historic fuel production, use and trade data sets published by the


▪ Abstract The effect of anthropogenic emissions from activities, such as fossil-fuel, biomass, and biofuel burning; transportation; and land-clearing; have a profound impact on the climate system.

Historical black carbon deposition in the Canadian High Arctic: a >250-year long ice-core record from Devon Island

Abstract. Black carbon aerosol (BC), which is emitted from natural and anthropogenic sources (e.g., wildfires, coal burning), can contribute to magnify climate warming at high latitudes by darkening



Trends in tropospheric aerosol loads and corresponding impact on direct radiative forcing between 1950 and 1990: A model study

Global aerosol optical thicknesses and radiative properties need to be known for the study of decadal temperature change. Aerosol distributions have been developed from global transport models for a

Climate forcing by carbonaceous and sulfate aerosols

Abstract An atmospheric general circulation model is coupled to an atmospheric chemistry model to calculate the radiative forcing by anthropogenic sulfate and carbonaceous aerosols. The latter

Origin of carbonaceous aerosols over the tropical Indian Ocean: Biomass burning or fossil fuels?

We present an analysis of the carbon, potassium and sulfate content of the extensive aerosol haze layer observed over the tropical Indian Ocean during the Indian Ocean Experiment (INDOEX). The black

Strong radiative heating due to the mixing state of black carbon in atmospheric aerosols

Simulation of the evolution of the chemical composition of aerosols finds that the mixing state and direct forcing of the black-carbon component approach those of an internal mixture, largely due to coagulation and growth of aerosol particles.

Evidence of surface cooling from absorbing aerosols

Anthropogenic emissions over the Asian region have grown rapidly with increase in population and industrialization. Air‐pollutants from this region lead to a brownish haze over most of the North

Chemical characterization of pollution layers over the tropical Indian Ocean: Signatures of emissions from biomass and fossil fuel burning

We have performed airborne measurements of atmospheric trace gases and aerosol composition on the National Center for Atmospheric Research C-130 research aircraft over the tropical Indian Ocean

Analysis of black carbon and carbon monoxide observed over the Indian Ocean: Implications for emissions and photochemistry

[1] Air from South Asia carries heavy loadings of organic and light-absorbing aerosol but low concentrations of ozone. We investigate ambient pollutant concentrations measured during the Indian Ocean

Contribution of road traffic emissions to the atmospheric black carbon burden in the mid-1990s

We developed a global inventory for black carbon (BC) emissions from road traffic for 1993. Global emissions of 2.4 TgC were found in this year. The inventory was implemented in the atmosphere
