For every 1 degree Celsius of anthropogenic global warming, some 21,000 people worldwide could die, including more than 1,000 in the U.S., says a new study in Geophysical Research Letters. According to computer modeling by researcher Mark Jacobson, increased air pollution due to rising carbon-dioxide levels will lead to more fatalities. “This is a cause and effect relationship, not just a correlation,” says Jacobson. Cities that already experience high air pollution will have the highest mortality rates. California, which has six of the 10 smoggiest cities in the U.S., “bears the brunt of climate change in terms of air pollution health problems,” says Jacobson. You hear that, EPA?
