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,... 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... 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... view more (2003-11-06)

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)

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... 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)

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)

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,... view more (1999-11-29)

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... view more (2003-11-21)

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... 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)

Explaining the methane mystery
Scientists have explained why atmospheric levels of the greenhouse gas methane have stabilised in recent years, but warn that increases could resume in the near future.   view more (2006-09-28)

Why is Greenland covered in ice?
There have been many reports in the media about the effects of global warming on the Greenland ice-sheet, but there is still great uncertainty as to why there is an ice-sheet there at all.   view more (2008-08-28)

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... view more (2005-06-23)

Decline in uptake of carbon emissions confirmed
A decline in the proportion of carbon dioxide (CO2) emissions absorbed by land and oceans is speeding up the growth of atmospheric CO2, according to a paper published today in the US Journal: Proceedings of the National Academy of Science.   view more (2007-10-25)

Rise in atmospheric CO2 accelerates as economy grows, natural carbon sinks weaken
Human activities are releasing carbon dioxide faster than ever, while the natural processes that normally slow its build up in the atmosphere appear to be weakening.   view more (2007-10-23)

Better measurements reveal seasonal changes in sulfur
Researchers from the University of Maryland (UMD) and the National Institute of Standards and Technology (NIST) have developed a new and improved technique for the simultaneous measurement of sulfur isotopic ratios and concentrations of atmospheric sulfate using snow samples from Greenland and... view more (2005-10-10)

Childhood cancers strongly linked to air pollution in early life
Childhood cancers are strongly linked to pollution from engine exhausts, concludes research in the Journal of Epidemiology and Community Health.   view more (2005-08-11)

£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)

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... view more (2002-07-12)

Prehistoric global warming may have contributed to fossil preservation
Prehistoric global warming episodes from massive atmospheric pollution involving carbon dioxide and methane could have created and preserved "mass kills" of wildlife, according to a University of Oregon study presented at the Geological Society of America's annual meeting.   view more (2005-10-13)

Soil nutrition affects carbon sequestration in forests
On December 11, USDA Forest Service (FS) scientists from the FS Southern Research Station (SRS) unit in Research Triangle Park, NC, along with colleagues from Duke University, published two papers in The Proceedings of the National Academy of Science (PNAS) that provide a more precise understanding... view more (2006-12-14)

Stratospheric ozone chemistry plays an important role for atmospheric airflow patterns
Interactions between the stratospheric ozone chemistry and atmospheric air flow lead to significant changes of airflow patterns from the ground up to the stratosphere.   view more (2008-03-10)
