A new measure of global warming from carbon emissions
Damon Matthews, a professor in Concordia University's Department of Geography, Planning and the Environment has found a direct relationship between carbon dioxide emissions and global warming. view more (2009-06-11)
Forests - just how absorbing are they?
Forests form an integral part of the Kyoto Protocol on climate change because they act as terrestrial "sinks" to soak up the carbon emissions that are contributing to global warming. Countries that have ratified the protocol can offset their carbon emissions quota by planting trees, either at home or in developing countries. But how... view more... (2003-03-13)
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)
Water acts as catalyst in explosives
The most abundant material on Earth exhibits some unusual chemical properties when placed under extreme conditions. view more (2009-03-23)
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)
New visualization techniques yield star formation insights
New computer visualization technology developed by the Harvard Initiative in Innovative Computing has helped astrophysicists understand that gravity plays a larger role than previously thought in deep space's vast, star-forming molecular clouds. view more (2009-01-05)
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)
Methane from microbes: a fuel for the future
Microbes could provide a clean, renewable energy source and use up carbon dioxide in the process, suggested Dr James Chong at a Science Media Centre press briefing today. view more (2007-12-11)
Engineered eggshells to help make hydrogen fuel
Engineers at Ohio State University have found a way to turn discarded chicken eggshells into an alternative energy resource. The patented process uses eggshells to soak up carbon dioxide from a reaction that produces hydrogen fuel. It also includes a unique method for peeling the collagen-containing membrane from the inside of the shells, so that... view more... (2007-09-27)
Emissions rising faster this decade than last
The latest figures on the global carbon budget to be released in Washington and Paris today indicate a four-fold increase in growth rate of human-generated carbon dioxide emissions since 2000. view more (2008-10-02)
Chemical Could Revolutionize Polymer Fuel Cells
Heat has always been a problem for fuel cells. There's usually either too much (ceramic fuel cells) for certain portable uses, such as automobiles or electronics, or too little (polymer fuel cells) to be efficient. view more (2005-08-25)
Laser pulses control single electrons in complex molecules
Predatory fish are well aware of the problem: In a swarm of small fish it is hard to isolate prey. A similar situation can be found in the microcosm of atoms and molecules, whose behavior is influenced by "swarms" of electrons. view more (2009-09-02)
Hubble finds carbon dioxide on an extrasolar planet
The NASA/ESA Hubble Space Telescope has discovered carbon dioxide in the atmosphere of a planet orbiting another star. view more (2008-12-10)
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)
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)
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)
New fuel cell catalyst uses 2 metals
Material scientists at Washington University in St. Louis have developed a technique for a bimetallic fuel cell catalyst that is efficient, robust and two to five times more effective than commercial catalysts. view more (2009-05-15)
Turning Waste Material into Ethanol
Say the word "biofuels" and most people think of grain ethanol and biodiesel. But there's another, older technology called gasification that's getting a new look from researchers at the U.S. Department of Energy's Ames Laboratory and Iowa State University. By combining gasification with high-tech nanoscale porous catalysts, they hope... view more... (2008-08-14)
Carbon offset warning from international team of scientists
Leading marine scientists from across the world have issued a warning that it is too early to sell carbon offsets from ocean iron fertilisation. view more (2008-01-11)
Seeing the forest and the trees helps cut atmospheric carbon dioxide
Putting a price tag on carbon dioxide emitted by different land use practices could dramatically change the way that land is used - forests become increasingly valuable for storing carbon and overall carbon emissions reductions become cheaper, according to research presented today at the annual meeting of the American Association for the... view more...
