The car company paid huge government penalties for its "clean diesel" claims in the U.S. but virtually nothing in Europe.
After a week of considering the evidence, a working group of the World Health Organization determined that diesel exhaust is carcinogenic in human lungs. Underground miners, bus drivers and railroad workers are especially vulnerable, but the risks from traffic exhaust extend to the general population.
The same day that President Obama released a message of new understanding and diplomacy to the Iranian people via his vlog, two U.S. Navy vessels collided in the Strait of Hormuz off southern Iran. More than 25,000 gallons of diesel fuel was spilled and 15 sailors were slightly injured.
