The federal Clean Air Act and associated environmental regulations have driven steep declines in air pollution emissions over the past several decades, even as U.S. manufacturers increased production, a study by two University of California, Berkeley, economists has shown.

One by one, Dr. Chris Opio and Chandehl Morgan carefully remove trees from one-gallon buckets.

Injecting particles into the atmosphere to cool the planet and counter the warming effects of climate change would do nothing to offset the crop damage from rising global temperatures, according to a new analysis by University of California, Berkeley, researchers.

Trying to tackle climate change by replacing forests with crops for bioenergy power stations that capture carbon dioxide (CO2) could instead increase the amount of CO2 in the atmosphere, scientists say.

The warming ocean may cause the larvae of bottom-dwelling snails to hatch earlier in the spring, when waves are larger, potentially impacting their ability to survive and serve as food for other sea creatures.

Protected riverbank habitats within areas of oil palm cultivation can play a key role in reducing the negative impacts on tropical bird numbers but need to be increased in size, new research from Kent has shown.

More than 6.1 million people worldwide die each year as a result of exposure to air pollution, which increases the risk of cardiovascular disease, lung disease, and cancer.

Researchers have found that people exposed to air pollution levels well within UK guidelines have changes in the structure of the heart, similar to those seen in the early stages of heart failure.

A team of researchers from Cologne and New York present proposals for the traffic management of the future. A dynamic and fair toll for road use could reduce congestion.

Kamita Gray and her mom have spent a lot of time volunteering at Brandywine Elementary School, helping kindergarteners learn to write their names and making sure everyone has a turkey on Thanksgiving and Christmas. Every time they’re at the Maryland school, they’re struck by the heavy black smoke from diesel trucks roaring by, en route from construction sites or delivering mining waste to dumps.
