Sulfate lens enhances climate warming properties of atmospheric soot
Particulate pollution thought to be holding climate change in check by reflecting sunlight instead enhances warming when combined with airborne soot, a new study has found. view more (2009-06-30)
Laboratory scientists study soot in megacity pollution
A team of Los Alamos scientists recently returned from a month-long data-gathering trip to Mexico City as part of an international, multi-agency environmental science collaboration. view more (2006-05-09)
Technologists develop robust soot filter for diesel engine
In a Technology Foundation STW project, Coen van Gulijk has developed a new concept for a robust soot filter for diesel engines. As well as filter stages, the filter has an open canal so as to exclude the danger of blockage and thus fire. The new soot filter consists of series of perforated ceramic foams. The surface of the ceramic is impregnated... view more... (2002-09-11)
Dirty snow causes early runoff in Cascades, Rockies
Soot from pollution causes winter snowpacks to warm, shrink and warm some more. This continuous cycle sends snowmelt streaming down mountains as much as a month early, a new study finds. view more (2009-01-12)
Cleaner diesels thanks to laser light
Measuring soot formation in a diesel engine is far from easy. Due to the turbulent environment in the combustion cylinder, no two combustion cycles are the same. view more (2007-12-10)
Toxicologists discover traces of diesel exhaust in the body
The Dutch toxicologists discovered that office staff, unloaders and drivers at an indoor transport company were exposed to almost the same extent as a result of ineffective ventilation of the office building. This shows how unreliable risk assessments based on occupational groups can be. To improve health conditions at work, it is necessary in... view more... (2000-02-21)
Scientists to Assess Beijing Olympics Air Pollution Control Efforts
As the Summer Olympics in Beijing kicks off this week, the event is giving scientists a once-in-a-lifetime opportunity to observe how the atmosphere responds when a heavily populated region substantially curbs everyday industrial emissions. view more (2008-08-11)
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)
£2.3 million invested in the air that we breathe
A new institute opens today (27 January 2004) which will refine the art and science of predicting air quality. Its work will give advance warning of when air will become seriously polluted, helping people whose health may be affected. view more (2004-01-23)
Increased atmospheric carbon dioxide promotes algal growth
It is usually thought that unlike terrestrial plants, submerged plants like algae will not show any response to an increase of atmospheric carbon dioxide. This view may be biased by a neglect of the effects of the plants themselves on the water chemistry. In the June issue of Ecology Letters, Schippers, Lürling and Scheffer of the Wageningen... view more... (2004-05-13)
Transported Black Carbon a Significant Player in Pacific Ocean Climate
Soot and other particulate pollution from Asian sources make up more than 75 percent of black carbon transported at high altitudes, according to a Scripps Institution of Oceanography, UC San Diego-led study. view more (2007-03-15)
Man-made soot contributed to warming in Greenland in the early 20th century
New research shows that industrial development in North America between 1850 and 1950 greatly increased the amount of black carbon--commonly known as soot-- that fell on Greenland's glaciers and ice sheets. view more (2007-08-10)
Spring agricultural fires have large impact on melting Arctic
Scientists from around the world will convene at the University of New Hampshire June 2-5, 2009, to discuss key findings from the most ambitious effort ever undertaken to measure "short-lived" airborne pollutants in the Arctic and determine how they contribute in the near term to the dramatic changes underway in the vast,... view more...

Gas-guzzling bacteria
The discovery of a new soil bacterium that consumes methane by oxidising it under atmospheric conditions is reported in Nature, out today. In well-drained soils, these methane-oxidising bacteria can reduce atmospheric levels of methane by 10 per cent. Methane is an important greenhouse gas, and over the last 200 years its concentration in the... view more... (2000-05-10)
The Mechanisms of Atmospheric Nucleation
Aerosol particles are ubiquitous in Earth's atmosphere, influencing the quality of life through their climatic and health effects and by affecting visibility. In recent years, the formation and growth of nanometer-scale particles have been observed in situ in many different atmospheric environments, including urban plumes, clean arctic air, the... view more...

New Director for the NERC Centres for Atmospheric Science
Professor Stephen Mobbs from the University of Leeds has been appointed as the next Director of the NERC Centres for Atmospheric Science (NCAS). He will take up his new role on 1 July 2005. view more (2005-04-15)
Soot from wood stoves in developing world impacts global warming more than expected
New measurements of soot produced by traditional cook stoves used in developing countries suggest that these stoves emit more harmful smoke particles and could have a much greater impact on global climate change than previously thought. view more (2006-10-25)
LSU scientist finds evidence of 'rain-making' bacteria
Brent Christner, LSU professor of biological sciences, in partnership with colleagues in Montana and France, recently found evidence that rain-making bacteria are widely distributed in the atmosphere. view more (2008-02-29)
An unexpected outcome of atmospheric CO2 enrichment
Unseen belowground interactions impact the composition of natural plant communities. Mycorrhizae, symbiotic associations between soil fungi and plant roots, help plants acquire soil nutrients but also drain substantial carbon from plants. Whether mycorrhizae help or hinder plant growth depends upon the balance between nutrient benefits and carbon... view more... (2003-05-22)
Unexpected growth in atmospheric CO2
A team of scientists has found that atmospheric carbon dioxide (CO2) growth has increased 35 percent faster than expected since 2000. The findings are published this week in the journal Proceedings of the National Academy of Sciences (PNAS). view more (2007-10-23)
