Drop in acid rain altering Appalachian stream water
Appalachian hardwood forests may be getting a respite from acid rain but data from a long-term ecological study of stream chemistry suggests that the drop in acid rain may be changing biological activity in the ecosystem and hiking dissolved carbon dioxide in forest streams. view more (2006-12-12)
Reducing greenhouse gases may not be enough to slow climate change
Because land use changes are responsible for 50 percent of warming in the US, policymakers need to address the influence of global deforestation and urbanization on climate change, in addition to greenhouse gas emissions. view more (2009-11-11)
NASA probes the sources of the world's tiny pollutants
Pinpointing pollutant sources is an important part of the ongoing battle to improve air quality and to understand its impact on climate. Scientists using NASA data recently tracked the path and distribution of aerosols — tiny particles suspended in the air — to link their region of origin and source type with their tendencies to warm... view more...

Compost can turn agricultural soils into a carbon sink, thus protecting against climate change
Applying organic fertilizers, such as those resulting from composting, to agricultural land could increase the amount of carbon stored in these soils and contribute significantly to the reduction of greenhouse gas emissions. view more (2008-02-25)
Oceans' uptake of manmade carbon may be slowing
The oceans play a key role in regulating climate, absorbing more than a quarter of the carbon dioxide that humans put into the air. view more (2009-11-19)
Dirty snow may warm Arctic as much as greenhouse gases
The global warming debate has focused on carbon dioxide emissions, but scientists at UC Irvine have determined that a lesser-known mechanism - dirty snow - can explain one-third or more of the Arctic warming primarily attributed to greenhouse gases. view more (2007-06-07)
Iowa State engineer works to clean and improve engine performance
The five engines in Song-Charng Kong's Iowa State University laboratory have come a long way since Karl Benz patented a two-stroke internal combustion engine in 1879. view more (2008-09-18)
Methane Eruptions On The Sea Floor - Science article: New evidence, new methods
Methane is a highly potent greenhouse gas. In its solid, ice form, called methane hydrate, it is stored in large amounts below the sea floor. Some signs indicate that there have been repeated intense undersea methane emissions over the course of the Earth's history. Often, these emissions appeared to be linked to climate changes, species... view more... (2003-02-19)
Engineered weathering process could mitigate global warming
Researchers at Harvard University and Pennsylvania State University have invented a technology, inspired by nature, to reduce the accumulation of atmospheric carbon dioxide (CO2) caused by human emissions. view more (2007-11-08)
Ceramic tubes could cut greenhouse gas emissions from power stations
Greenhouse gas emissions from power stations could be cut to almost zero by controlling the combustion process with tiny tubes made from an advanced ceramic material. view more (2007-08-03)
Powerful new tool to track carbon dioxide by source
Scientists from NOAA's Earth System Research Laboratory released today a powerful new tool to monitor changes in atmospheric carbon dioxide and other greenhouse gases by region and source around the world. Called CarbonTracker, the online system will distinguish between changes in the natural carbon cycle and those occurring in fossil fuel... view more... (2007-03-22)
First-ever study to link increased mortality specifically to carbon dioxide emissions
A Stanford scientist has spelled out for the first time the direct links between increased levels of carbon dioxide in the atmosphere and increases in human mortality, using a state-of-the-art computer model of the atmosphere that incorporates scores of physical and chemical environmental processes. view more (2008-01-04)
Air pollutants from abroad a growing concern, says new report
Plumes of harmful air pollutants can be transported across oceans and continents -- from Asia to the United States and from the United States to Europe -- and have a negative impact on air quality far from their original sources, says a new report by the National Research Council. view more (2009-09-30)

Wildfires Cause Ozone Pollution to Violate Health Standards, New Study Shows
Wildfires can boost ozone pollution to levels that violate U.S. health standards, a new study concludes. view more (2008-10-10)
Fires fuel mercury emissions, U-M study finds
Forest fires release more mercury into the atmosphere than previously recognized, a multidisciplinary research project at the University of Michigan suggests. view more (2007-01-10)
Invitation to a Press Conference:Commissions Joint Research Centre efforts to reduce air pollution from traffic - 10 December 2003, Milano Italy
Who? The European Commission's Joint Research Centre (JRC) DG, in collaboration with the Lombardy Region of Italy, with the support of DG ENV, DG ENTR and of the Italian EU presidency What? Press conference on the official agreement (Memorandum of... view more... (2003-12-08)
More star births than astronomers have calculated
The "birth rate" for stars is certainly not easy to determine. Distances in the universe are far too great for astronomers to be able to count all the newly formed celestial bodies with the aid of a telescope. view more (2008-10-02)
Is global warming unstoppable?
In a provocative new study, a University of Utah scientist argues that rising carbon dioxide emissions - the major cause of global warming - cannot be stabilized unless the world's economy collapses or society builds the equivalent of one new nuclear power plant each day. view more (2009-11-23)
Climate studies to benefit from 12 years of satellite aerosol data
Aerosols, very small particles suspended in the air, play an important role in the global climate balance and in regulating climate change. view more (2009-11-11)
