Increased environmental carbon levels - the good news!
Increasing carbon levels can be a good thing in some cases: scientists at the University of Durham propose that higher levels of inorganic carbon can have a positive influence on human health. View More (2006-04-03)
Global warming may not have ended Ice-Age, says research
Scientists at the University of Sheffield have used fossilised leaves to determine the effect of greenhouse gases on the end of the Ice Age 300m years ago, according to an article published in PNAS. The study, led by Professor David Beerling, examined fossilised leaves to determine how much carbon dioxide was in the air at various periods during the ice age. Leaves have pores on their surface...

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)
Carbon turns over much faster through basal food-chain levels in aquatic than in terrestrial ecosystems
Global temperatures have increased dramatically over the past century, which is causing major impacts on climate patterns, ocean circulation and wildlife preservation. The increase in temperature is largely due to a rise of anthropogenic emissions of greenhouse gases, of which CO2 is one of the most important. To understand the capacity of ecosystems to sequester excesses of atmospheric CO2 and... View More (2004-02-25)
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. This nutrient may have drastically altered the... View More (2001-06-21)
Plants' fungi allies may not help store climate change's extra carbon
Fungi found in plants may not be the answer to mitigating climate change by storing additional carbon in soils as some previously thought, according to an international team of plant biologists. View More (2012-08-31)
Geochemist raises questions about carbon sequestration at Goldschmidt Conference
As carbon dioxide levels in the atmosphere rise, policy makers and scientists are looking at new ways to tackle the problems associated with the greenhouse gas. View More (2010-06-16)
Can biofuels be sustainable?
With oil prices skyrocketing, the search is on for efficient and sustainable biofuels. Research published this month in Agronomy Journal examines one biofuel crop contender: corn stover. View More (2008-08-20)
Transcontinental wildfire emissions monitored from space
Using data from the SCIAMACHY instrument aboard ESA's environmental satellite Envisat, scientists have determined that the carbon monoxide hovering over Australia during the wildfire season largely originated from South American wildfires some 13 000 kilometres away. View More (2007-05-09)
Confirmed - deforestation plays critical climate change role
Dr Pep Canadell, from the Global Carbon Project and CSIRO Marine and Atmospheric Research, says today in the journal Science that tropical deforestation releases 1.5 billion tonnes of carbon each year into the atmosphere. View More (2007-05-14)
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 University show that, if this effect is included,... View More (2004-05-13)
Air traffic poised to become a major factor in global warming
The first new projections of future aircraft emissions in 10 years predicts that carbon dioxide and other gases from air traffic will become a significant source of global warming as they double or triple by 2050. View More (2010-05-27)
Carbon monoxide linked to heart problems in elderly
Exposure to carbon monoxide, even at levels well below national limits, is associated with an increased risk of hospitalization for the elderly with heart problems, according to a study published today in Circulation: Journal of the American Heart Association. View More (2009-09-01)
Scrubbing CO2 from atmosphere could be a long-term commitment
With carbon dioxide in the atmosphere approaching alarming levels, even halting emissions altogether may not be enough to avert catastrophic climate change. Could scrubbing carbon dioxide from the air be a viable solution? View More (2010-07-02)
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.

Global warming likely to be amplified by slow changes to Earth systems
Researchers studying a period of high carbon dioxide levels and warm climate several million years ago have concluded that slow changes such as melting ice sheets amplified the initial warming caused by greenhouse gases. View More (2009-12-21)
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 atmosphere has doubled. But, until now, its low levels... View More (2000-05-10)
Carbon dioxide may explain 'near death experiences'
Near death experiences (NDEs), reported to include sensations such as life flashing before the eyes, feelings of peace and joy, and apparent encounters with mystical entities, may be caused by raised levels of carbon dioxide in the blood. View More (2010-04-08)
Carbon dioxide and climate - the plot thickens
Using a novel technique, the researchers obtained a best estimate for carbon dioxide levels 43 million years ago of 385 parts per million (ppm), slightly higher than today's figure of 360 ppm. This result is far below earlier estimates which suggested that carbon dioxide levels were up to six times present day values. There are two ways to interpret these new findings; one may give comfort to... View More (1999-06-08)
New isotope cluster could lead to better understanding of atmospheric carbon dioxide
A team of researchers has discovered an unexpected concentration of a certain isotopic molecule in parts of the stratosphere that could have implications for understanding the carbon cycle and its response to climate change. View More (2009-07-15)
