Choking smog in China
Beijing The cloud of pollution over Beijing grew so dense this week that much of the city was rendered invisible. Hundreds of flights were grounded, auto traffic was stalled for scores of miles, and residents rushed to buy masks and air filters. Chinese officials downplayed the air-quality crisis, as usual, saying their readings showed that air pollution was “moderate.” But […]
Read moreAutism Linked With Prenatal Exposure To Traffic Pollution
Babies exposed to air pollution in the womb are more likely to have autism than those whose mothers spend pregnancy in clean air, according to a new study. In the largest study of its kind, UCLA researchers compared levels of air pollutants, mostly related to vehicle traffic, during pregnancy gestation periods of 7,603 children with autism and 75,635 children without […]
Read moreMore certainty on global warming
An influential panel of climate scientists has expressed higher confidence than ever that human activity is the main cause of the rise in global temperatures since the 1950s, Reuters.com reports. A leaked draft of an upcoming report of the United Nations’ Intergovernmental Panel on Climate Change, based on a broad analysis of published scientific studies, concludes with 95 percent certainty […]
Read morePollution’s links to autism
A new study has found the strongest link yet between air pollution and autism, which experts now say affects one in 50 U.S. schoolchildren. Pregnant women who lived in areas with high levels of diesel exhaust and airborne mercury were found to be twice as likely to have a child with autism as those living in places with the lowest […]

Red lights may prevent deadly auto accidents, but waiting at one poses a different kind of hazard to your health. Car exhausts emit harmful pollutants, known as nanoparticles, which have been linked to heart and lung disease. When researchers from the University of Surrey in England analyzed drivers’ exposure to these pollutants at various points in their typical daily commutes, […]

The oil released during the BP Deepwater Horizon disaster may damage fish populations in the Gulf of Mexico for years to come. New research from the National Oceanic and Atmospheric Administration found that exposure to crude oil can cause heart defects in fish embryos—abnormalities that will likely kill many developing fish and shorten the lives of others. The study looked […]
Read moreReef madness
It seemed like a good idea at the time. In 1972, Broward County, Fla., organized more than 100 boats to dump an estimated 700,000 tires into the Atlantic Ocean in hopes of sparking the growth of an artificial reef. Ultimately corals never grew on the bundles of tires, and over time the bundles became loose, causing damage to nearby natural […]
Read moreAcknowledging Beijing’s Pollution
The smog which suffocates Beijing has gotten so bad that the Chinese media has concluded that something must be done. Poor visibility has led to canceled flights and highway closings. The level of particulates in the air topped 35 times the World Health Organization’s safety limit. China’s new leaders “appear to be sending a signal that they want to allow […]

Until recently, Pakistan has not used the bulk of its coal reserves – some of the largest in the world – for power generation. Within the past year the government in Islamabad has signed a number of financial and technological agreements with China aimed at exploiting massive coal reserves at the Tharparkar mine in Sindh province, in the south of the […]
