Until now, scientists who study air pollution using satellite imagery have been limited by weather. Clouds, in particular, provide much less information than a sunny day.
No matter how you drill it, using natural gas as an energy source is a smart move in the battle against global climate change and a good transition step on the road toward low-carbon energy from wind, solar and nuclear power.
Elevated levels of atmospheric carbon dioxide accelerate carbon cycling and soil carbon loss in forests, new research led by an Indiana University biologist has found.
Satellite measurements show that nitrogen dioxide in the lower atmosphere over parts of Europe and the US has fallen over the past decade.
An international team that includes scientists from Johannes Gutenberg University Mainz (JGU) has published a reconstruction of the climate in northern Europe over the last 2,000 years based on the information provided by tree-rings.
Studies by U.S. Department of Agriculture (USDA) scientists show some no-till management systems can lower atmospheric levels of PM10—soil particles and other material 10 microns or less in diameter that degrade air quality—that are eroded from crop fields via the wind.
A new study led by the University of Colorado Boulder indicates air pollution in the form of nitrogen compounds emanating from power plants, automobiles and agriculture is changing the alpine vegetation in Rocky Mountain National Park.
The U.S. Environmental Protection Agency is proposing to approve Arizona’s air quality plan to control sulfur dioxide and soot at three power plants in the state.
Some coral reef fish may be better prepared to cope with rising CO2 in the world's oceans -- thanks to their parents.
An international team of astronomers using data from NASA's Hubble Space Telescope has made an unparalleled observation, detecting significant changes in the atmosphere of a planet located beyond our solar system.
For eastern Pacific populations of leatherback turtles, the 21st century could be the last. New research suggests that climate change could exacerbate existing threats and nearly wipe out the population.
A new study with NASA participation has sharply reduced previous estimates of how much carbon was emitted into Earth's atmosphere from tropical deforestation in the early 2000s.
The U.S. Environmental Protection Agency (EPA) and the U.S. Department of Justice (DOJ) announced a Clean Air Act (CAA) settlement with Dairyland Power Cooperative (DPC) that will cover the utility’s three power plants in Alma and Genoa, Wis.
The exhaust from diesel-fueled vehicles, wood fires and coal-driven power stations contains small particles of soot that flow out into the atmosphere. The soot is a scourge for the climate but also for human health.
The U.S. Environmental Protection Agency and the San Joaquin Valley Air Pollution Control District today announced a Clean Air Act settlement with Ralcorp’s Cottage Bakery in Lodi, Calif. after the facility failed to obtain permits and install proper air pollution controls.
A new study with NASA participation has sharply reduced previous estimates of how much carbon was emitted into Earth's atmosphere from tropical deforestation in the early 2000s.
The Polyisocyanurate Insulation Manufacturers Association (PIMA) has released a new study that analyzes and quantifies the energy and environmental contribution of polyisocyanurate insulation (polyiso) over the past 25 years.
Unhealthy air quality is predicted for the southern portions of Connecticut and Rhode Island, and the south coast of Massachusetts, including Cape Cod and the Islands, on Wednesday due to ground-level ozone.
Carbon stored in Arctic tundra could be released into the atmosphere by new trees growing in the warmer region, exacerbating climate change, scientists have revealed.
The U.S. Environmental Protection Agency (EPA) has proposed updates to its national air quality standards for harmful fine particle pollution, including soot (known as PM2.5).
