Study finds that prenatal exposure to coal-plant emissions impedes neurodevelopment

A major new study by the Columbia Center for Children's Environmental Health finds: Closing coal-fired power plants can have a direct, positive impact on children's cognitive development and health ... [P]renatal exposure to coal-burning emissions was associated with significantly lower average developmental scores and reduced motor development at age two. In the second unexposed group, these adverse effects were no longer observed; and the frequency of delayed motor developmental was significantly reduced. The full study [PDF] in the July 14 Environmental Health Perspectives is available online: "Benefits of Reducing Prenatal Exposure to Coal Burning Pollutants to Children's Neurodevelopment in China." The study provides yet more evidence -- if any were needed -- that we need to ban traditional coal plants: "elimination of prenatal exposure to coal-burning emissions resulted in measurable benefits to children's development." This is a sophisticated study, which used molecular markers to directly track exposure to coal plant emissions:

Hog heaven, part 2

Climate action requires leadership beyond political ‘reasonableness’

This post is by ClimateProgress guest blogger Bill Becker, executive director of the Presidential Climate Action Project. Let's face it: The Bush Administration has made a mess of things, as noted in "Hog heaven, part 1." It is now clear, if it hasn't been all along, that by the time George Bush leaves office, the White House will have wasted eight years of leadership on the Mother of All Issues. If those eight years are a profound disappointment looking backward, then they are a profound tragedy looking forward. The head of the IPCC is spreading the message that the world community has seven short years to act decisively to curb greenhouse-gas emissions. Dr. John Holdren is among the prestigious U.S. scientists who now say more openly that the effects of climate change already are upon us. Dr. Jim Hansen now estimates that atmospheric concentrations of carbon must level off at 350 ppm, nearly 30 percent lower than everyone thought was needed to keep climate change at "safe" levels. Anyone who's paying attention sees that the impacts of global warming are occurring much faster than predicted. If this year's weather extremes are a sample of climate change, how much worse will they be 10 years, 20 years, or 30 years from now, as today's rising and accumulating emissions take their toll?
