'Rivers on Rolaids': How acid rain is changing waterways

Something peculiar is happening to rivers and streams in large parts of the United States — the water's chemistry is changing. Scientists have found dozens of waterways that are becoming more alkaline.

50 years after its discovery, acid rain has lessons for climate change

In the 1980s, the dying red spruce trees of New England—many of them taller than eight-story buildings and more than three centuries old—furnished frightening proof of the power of acid rain.

Eastern U.S. water supplies threatened by a legacy of acid rain

Millbrook, NY – Human activities are changing the water chemistry of many streams and rivers in the Eastern U.S., with consequences for water supplies and aquatic life, so reports a new study in the journal Environmental Science and Technology.

Decreased water flow may be trade-off for more productive forest

Bubbling brooks and streams are a scenic and much loved feature of forest ecosystems, but long-term data at Hubbard Brook Experimental Forest suggests that more productive forests might carry considerably less water.

Acid rain: Progress but not triumph

Podcast

Though not in the news as much as it once was, acid rain remains a problem. Power plants, factories, and vehicles give off sulfur and nitrogen oxide emissions, which react in the atmosphere to form sulfuric and nitric acids. These acids are then deposited back onto the landscape in rain, snow, fog, or particles.

Untangling climate impacts on forests

In assessing a major drop in nitrate loss from the Hubbard Brook Experimental Forest, it was revealed that past disturbances, such as logging, must be included.

Acid Rain: A Long, Unfinished Journey From Discovery to Political Action

Lecture Video

Dr. Gene E. Likens, Founding Director of the Cary Institute and co-discoverer of acid rain in North America discusses the science behind acid rain and the policies needed to stop it from falling.

New rule tackles air pollution

We ecologists take a lot of flack for always having depressing news to report. It's not often we get to say there is good news on the environmental front, but those of us concerned with air pollution have certainly had reasons to smile this summer.

Climate shift fails to curtail acid rain

Climate change predictions for the northeastern United States call for an increase in: precipitation, winter rain, winter flooding, and the frequency of nor'easters.

Airborne pollutants harm diverse habitats

If you are living in the eastern United States, the environment around you is being harmed by air pollution.

Acid rain problem lingers

Cary Institute scientists have provided leadership in acid rain research, but acid rain is not limited to our area—it occurs widely across the eastern United States, Europe, China, and other industrialized areas around the world.

Gene E. Likens awarded the National Medal of Science

Fourteen scientists and one engineer were named by President George W. Bush on May 9, 2002 to receive the National Medal of Science, the nation's highest award for lifetime achievement in fields of scientific research.
