Study estimates California’s GHG reductions since 2003 could be wiped out by 2020 wildfires

Green Car Congress

In an open-access report in the journal Environmental Pollution , researchers from UCLA and the University of Chicago estimate that California’s wildfire carbon dioxide equivalent (CO 2 e) emissions from 2020 (~127 mmt CO 2 e ) are approximately two times higher than California’s total greenhouse gas (GHG) emission reductions since 2003.

Researchers in China investigate use of coal as source of lithium

Green Car Congress

Coal could become a major source of the metal lithium, according to a review of the geochemistry by scientists from Hebei University of Engineering in China published in the International Journal of Oil, Gas and Coal Technology. The second approach, alkali sintering, avoids the need for the sulfur step but has a lower yield at 85.3%

Study: surface ozone in India in 2005 damaged 6M tonnes of crops, enough to feed 94M people in poverty

Green Car Congress

Ozone, the main component of smog, is a plant-damaging pollutant formed by emissions from vehicles, cooking stoves and other sources. New research shows that ozone pollution damaged millions of tons of wheat, rice, soybean and cotton crops in India in 2005. Surface ozone pollution in India damaged 6 million metric tons (6.7

Study of lead isotopes provides insight into aerosols transport from Asia to US

Green Car Congress

About a third of the airborne lead particles collected at two sites in the San Francisco Bay Area came from Asia, a finding that underscores the far-flung impacts of air pollution and heralds a new way to learn more about its journey across vast distances. They found that a median value of 29% of the lead particles were of Asian origin.
