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)

Breakthrough in plant research
The research groups of the Department of Biological and Environmental Sciences of the University of Helsinki and the University of California in San Diego have discovered a gene that is centrally involved in the regulation of carbon dioxide uptake for photosynthesis and water evaporation in plants.   view more (2008-02-28)

HOW TREES CHANGED THE WORLD
Before 380 million years (Ma) ago, the continents had only patches of mosses and algae with no tree cover. The effect of the evolution of trees (large vascular plants with deep, extensive roots) changed the world for ever, according to Dr Robert Berner (Yale University). He presents his findings at... view more (2001-06-21)

Hold your breath; Plants may absorb less carbon dioxide than we thought
The world's land plants will probably not be able to absorb as great a share of the rising atmospheric carbon dioxide as some models have predicted.   view more (2006-04-13)

Scientists find key to ocean bacterium that helps control greenhouse gas
Scientists are a step closer to understanding how the world's oceans influence global warming - as well supply us with the oxygen we breathe. A study led by Imperial College London has revealed how the most abundant ocean bound photosynthetic bacterium helps control levels of the greenhouse gas,... view more (2003-08-27)

Emissions irrelevant to future climate change?
Climate change and the carbon emissions seem inextricably linked. However, new research published in BioMed Central's open access journal Carbon Balance and Management suggests that this may not always hold true, although it may be some time before we reach this saturation point.   view more (2008-04-28)

Research on how plants transport sugars could be of critical importance in era of global warming
How do many plants ship sugars from their leaves to flowers, roots, fruits and other parts of their structure? Using genetic engineering techniques, Cornell researchers have finally proven a long-standing theory of how this occurs.   view more (2007-12-26)

Tropical rainforest nutrients linked to global carbon dioxide levels
Extra amounts of key nutrients in tropical rain forest soils cause them to release more carbon dioxide into the atmosphere, according to research conducted by scientists at the University of Colorado (CU)—Boulder.   view more (2006-06-21)

Global atmospheric carbon level may depend primarily on Southern Ocean
Circulation in the waters near the Antarctic coast may be one of the planet's critical means of regulating levels of carbon dioxide in the Earth's atmosphere, according to Princeton researchers.   view more (2006-06-23)

Food source threatened by carbon dioxide
Carbon dioxide increasing in the atmosphere may affect the microbial life in the sea, which could have an impact on a major food source, warned Dr Ian Joint at a Science Media Centre press briefing today.   view more (2007-12-11)

Mars Express confirms methane in the Martian atmosphere
During recent observations from the ESA Mars Express spacecraft in orbit around Mars, methane was detected in its atmosphere. Whilst it is too early to draw any conclusions on its origin, exciting as they may be, scientists are thinking about the next steps to take in order to understand more.... view more (2004-03-30)

Northern forests less effective than tropical forests in reducing global warming
Forests in the United States and other northern mid- and upper-latitude regions are playing a smaller role in offsetting global warming than previously thought, according to a study appearing in this week's issue of Science.   view more (2007-06-25)

Southern Ocean could slow global warming
The Southern Ocean may slow the rate of global warming by absorbing significantly more heat and carbon dioxide than previously thought, according to new research.   view more (2006-12-06)

North Sea efficient sink for carbon dioxide
The measured annual increase in the concentration of carbon dioxide (CO2) in the atmosphere is only 60 percent of the annual emissions from fossil fuels.   view more (2005-10-11)

Global climate change: a load of poo?
Plankton poo could be the key to understanding how much carbon dioxide our oceans can store according to Tasmanian researcher Dr Karin Beaumont.   view more (2004-09-09)

Identification of carbon dioxide receptors in insects may help fight infectious disease
Mosquitoes don't mind morning breath. They use the carbon dioxide people exhale as a way to identify a potential food source. But when they bite, they can pass on a number of dangerous infectious diseases, such as malaria, yellow fever, and West Nile encephalitis.   view more (2006-12-14)

Deep-sea sediments could safely store man-made carbon dioxide
An innovative solution for the man-made carbon dioxide fouling our skies could rest far beneath the surface of the ocean, say scientists at Harvard University.   view more (2006-08-08)

Carbon dioxide laser resurfacing may reduce wrinkles over long term
Carbon dioxide laser resurfacing appears to be an effective long-term treatment for facial wrinkles, according to a report in the July/August issue of Archives of Facial Plastic Surgery, one of the JAMA/Archives journals.   view more (2008-07-22)

Increase in atmospheric moisture tied to human activities
Observations and climate model results confirm that human-induced warming of the planet is having a pronounced effect on the atmosphere's total moisture content.   view more (2007-09-18)

Storage of greenhouse gasses in Siberian peat moor
Wet peat moorlands form a sustainable storage place for the greenhouse gas carbon dioxide but are also a source of the much stronger greenhouse gas methane. According to Dutch researcher Wiebe Borren, peat moorlands will counteract the greenhouse effect under the present climatic conditions.   view more (2007-01-31)

Water vapor confirmed as major player in climate change
Water vapor is known to be Earth's most abundant greenhouse gas, but the extent of its contribution to global warming has been debated.   view more (2008-11-18)

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)

First buoy to monitor ocean acidification launched
The first buoy to monitor ocean acidification has been launched in the Gulf of Alaska. Attached to the 10-foot-diameter buoy are sensors to measure climate indicators.   view more (2007-06-13)

Rivers are carbon processors, not inert pipelines
Microorganisms in rivers and streams play a crucial role in the global carbon cycle that has not previously been considered.    view more (2008-12-02)
