of the human-made climate impact; two-thirds of this impact are caused by emissions other than CO 2 , according to a new study by researchers in Europe and the US. The study was published in the journal Atmospheric Environment. Here, we present a new comprehensive and quantitative approach for evaluating aviation climate forcing terms.

Black carbon is a much larger cause of climate change than previously assessed; about twice previous estimates, and 2/3 the effect of CO2

Green Car Congress

Accounting for all of the ways black carbon can affect climate, it is believed to have a warming effect of about 1.1 Emission rates of BC in the year 2000 by region, indicating major source categories in each region. Black carbon aerosol plays a unique and important role in Earth’s climate system. Source: Bond et al.
