Carbon dioxide pollution kills hundreds a year - study

WASHINGTON (Reuters) - Climate-warming carbon dioxide spewed by coal-fired power plants and fossil-fueled vehicles has been causing hundreds of premature U.S. deaths each year over the several decades, a new study reported.

The deaths were due to lung and heart ailments linked to ozone and polluting particles in the air, which are spurred by carbon dioxide that comes from human activities, according to the study's author, Mark Jacobson of Stanford University.
