Immediate Cut in Soot Emissions Is Big Boost for Environment

GreenTracker| Cutting soot emissions from the burning of fossil fuels and solid biofuels contributes far more to global warming than previously thought. In Feb. we published Black Carbon from India, Not Greenhouse Gases, Primary Cause of Himalayan Glacier Melt.

Without exempting the critical need to reduce greenhouse gases, the new research suggests that attacking soot should become a top priority. Unlike carbon dioxide, soot lingers only a few weeks in the atmosphere, so cutting emissions could have a significant and rapid impact on the climate. Cutting soot could save more than 1.5 million premature deaths worldwide, say Stanford researcher Mark Z. Jacobson.

Jacobson’s research is based on computer modeling. The earlier Berkeley research resulted from analysis of current data.
