Environmental toxicology expert witnesses may report on pollutants, black carbon and soot. The Journal of Geophysical Research has published a new study showing black carbon ranks #2 as a human contributor to climate change. Emissions from diesel engines and wood and coal fires create soot which contributes to hazardous air quality such as that seen in Beijing recently. Soot falls between carbon dioxide and methane in global warming caused by man.
The Journal of Geophysical Research is published by The American Geophysical Union, established in 1919, is a nonprofit corporation chartered under the laws of the District of Columbia. The Union is dedicated to the furtherance of the geophysical sciences through the individual efforts of its members and in cooperation with other national and international scientific organizations.
