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)
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)
New method for growing barium titanate films at atmospheric pressure
The localized hydrothermal technique: A new method for growing barium titanate films at atmospheric pressure. view more (2005-09-28)
Sometimes dry soils yield more clouds
Symposium of the American Meteorological Society in Wageningen (The Netherlands) Cloud formation does not always follow beaten tracks. The formation of low clouds during nice weather conditions will normally take place above moist soils. Under specific atmospheric conditions, which can occur in Europe, drier soils yield more clouds, according to a... view more... (2002-07-12)
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)
New laboratory to study the oceans and air
Almost two-thirds of the planet is ocean and this has a major impact on our lives. Now the University of East Anglia (UEA) will be home to the world's first facility dedicated to the study of chemical ocean-air interactions which are important in regulating Earth's climate. Examples include ocean uptake of greenhouse gases such as carbon dioxide... view more... (2003-11-21)
Clemson scientists launch rockets to test atmospheric conditions
Clemson University space physicists have traveled around the world to launch rockets to test atmospheric conditions. view more (2009-02-27)
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)
How will the Arctic sea ice cover develop this summer?
The ice cover in the Arctic Ocean at the end of summer 2008 will lie, with almost 100 per cent probability, below that of the year 2005 - the year with the second lowest sea ice extent ever measured. view more (2008-07-10)
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)
Deep sea algae connect ancient climate, carbon dioxide and vegetation
Assistant Professor Mark Pagani in the Department of Geology and Geophysics at Yale and his colleagues mapped the first detailed history of atmospheric carbon dioxide between 45-25 million years ago based on stable isotopes of carbon in a National Science Foundation study reported in Science Express. view more (2005-06-23)
Groundbreaking Canada-US study proves link between emissions and mercury pollution in fish
A groundbreaking environmental study to be published in a prestigious American science journal proves that mercury atmospheric emissions will end up in fish in as little as three years. view more (2007-09-18)
Antarctic snow inaccurate temperature archive
According to Dutch researcher Michiel Helsen, annual and seasonal temperature fluctuations are not accurately recorded in the composition of the snow of Antarctica. His research into the isotopic composition of the Antarctic snow has exposed the complexity of climate reconstructions. view more (2006-02-16)
Food could be made safer by surface decontamination with steam
Trials have been carried out using steam below, at, or above atmospheric pressure. As the pressure of the steam is increased, higher decontamination temperatures can be achieved. Comparative studies are also assessing the use of treatments with hot air, water immersion, infrared irradiation, ultraviolet (UV) light, microwaves, or ozone. view more (1999-11-29)
Role of Silica in Climate Cycles
New research from the University of East Anglia (UEA) has demonstrated that the compound silica was not solely responsible for changes in carbon dioxide levels during past Ice Ages. It is already known from scientific research that during past Ice Ages increased amounts of silica, a common component of wind-blown dust, were deposited in the ocean.... view more... (2001-06-21)
Higher carbon dioxide, lack of nitrogen limit plant growth
Earth's plant life will not be able to "store" excess carbon from rising atmospheric carbon dioxide levels as well as scientists once thought because plants likely cannot get enough nutrients, such as nitrogen, when there are higher levels of carbon dioxide view more (2006-04-13)
Naval Research Laboratory's ANDE-2 deployed from Space Shuttle Endeavour
The Naval Research Laboratory's satellite suite, the Atmospheric Neutral Density Experiment 2 (ANDE-2), was deployed from NASA's Space Shuttle Endeavour on July 30, 2009. view more (2009-08-06)
Tropical storms endure over wet land, fizzle over dry
If it has already rained, it's going to continue to pour, according to a Purdue University study of how ocean-origin storms behave when they come ashore. view more (2009-08-27)
Scientists Test System to Forecast Flash Floods along Colorado's Front Range
People living near vulnerable creeks and rivers along Colorado's Front Range may soon get advance notice of potentially deadly floods, thanks to a new forecasting system being tested this summer by the National Center for Atmospheric Research (NCAR) in Boulder, Colo. view more (2008-07-23)
