...energy means carbon, and China's booming economy puts it on a path to become the world's No. 1 greenhouse-gas emitter as early as 2020. Li knows that China needs clean energy as badly as the developed world needs China to clean up, which is why he joined the Tsinghua-BP Clean Energy Research and Education Center as director when it opened in July 2003. The center's most promising project is a new technology called polygeneration, by which coal is converted into a cleaner gaseous fuel that can both generate electricity and be processed into a petroleum...
Although air pollution in Delhi has stabilized, the fight for clean air is far from won. Some 400 to 600 new private cars roll onto the city's streets every day. Narain and Lal don't claim to have slowed global warming. But their efforts have attracted requests for advice from as far away as Kenya and Indonesia. "Delhi leapfrogged," Narain says with a grin. "People noticed." --By Alex Perry/New Delhi...
...immediate hazard is drowning, but the larger issue is water quality. To take just one example, more than 700 U.S. cities--most of them older communities in the Northeast, Northwest and Great Lakes area--have sewer systems that regularly overflow into water supplies during heavy rainstorms, mixing dirty and clean water and sometimes requiring mandatory boiling to make contaminated tap water safe. A heavy rainfall preceded the majority of waterborne-disease outbreaks in the U.S. over the past 60 years, says Dr. Jonathan Patz of the University of Wisconsin at Madison...
...thing about all those predictions is that you can't point to any outbreak or any individual's death and say, "This occurred because of climate change." But we know that good public health relies on a long list of factors--the availability of doctors and nurses, effective medicines, clean water, proper sanitation--and that even today, millions of people die every year of what should be preventable diseases. With global warming, you can expect the death toll to be even higher...
...industrialized world. India, though behind its Asian rival, could see greenhouse-gas emissions that rise 70% by 2025, according to the World Resources Institute. But the nearly double-digit growth rates that are responsible for those nightmare projections also present an environmental opportunity. "Anything you want to do about clean energy is easier to do from the outset," says David Moskowitz, an energy consultant who has advised Chinese officials. "Every time they add a power plant or factory, they can add one cleaner and better than before." If China and India can muster the will and resources to leapfrog...
