Scientists are reporting the first evidence that China's sharp focus on reducing widespread damage to soil by acid rain by restricting sulfur dioxide air pollution may have an unexpected consequence: Gains from that pollution control program will be largely offset by increases in nitrogen emissions, which the country's current policy largely overlooks.
New research shows that air pollution in eastern China has reduced the amount of light rainfall over the past 50 years and decreased by 23 percent the number of days of light rain in the eastern half of the country.
WASHINGTON, May 1 /PRNewswire/ -- Argus Media testified at a Senate roundtable last week to urge Congress to take action on emissions trading, because Environmental Protection Agency (EPA) rules may be subject to further legal challenge.

Welsh scientists say a 25-year study suggests climate change might be hampering the recovery of Earth's rivers from the effects of acid rainfall. The research by Cardiff University Professor Steve Ormerod and biosciences researcher Isabelle Durance was undertaken in 14 middle-Wales rivers and involved assessing the number and variety of stream insects present each year.
Acid rain is any form of precipitation that is unusually acidic, meaning that is possesses high levels of hydrogen ions. It can have harmful effects on aquatic animals, plants, and infrastructure. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide, which react with the water molecules within the atmosphere to produce acids. Nitrogen oxides can be produced naturally by lightening strikes. Sulfur dioxide can be produced naturally by volcanic eruptions. The chemicals that are...
Rain is a type of liquid precipitation. It is defined as condensation of atmospheric water vapor that forms into drops that become heavy enough to fall, and often making it to the surface. Rain is the primary source of most of the fresh water in the world. Rain provides suitable conditions for diverse ecosystems, water for power sources and for crop irrigation. Not all rain reaches the surface. Some rain evaporates as it falls, especially through dry air. This type of rainfall is known as...
