Engineered weathering process could mitigate global warming
Researchers at Harvard University and Pennsylvania State University have invented a technology, inspired by nature, to reduce the accumulation of atmospheric carbon dioxide (CO2) caused by human emissions. view more (2007-11-08)
Climate gas could disrupt food chain
Levels of a climate cooling gas will change as carbon dioxide increases, affecting food webs along the way, said Dr Michael Steinke at a Science Media Centre press briefing today. view more (2007-12-11)
Ancient climate change may portend toasty future
Scientists, including Ken Caldeira of the Carnegie Institution's Department of Global Ecology, have found that the Earth's global warming, 55 million years ago, may have resulted from the climate's high sensitivity to a long-term release of carbon. view more (2006-12-08)
Rising carbon dioxide levels increase risks to satellites
Climate change is widely attributed to the build-up of greenhouse gases, such as carbon dioxide, in the Earth's atmosphere. However, scientists from the School of Engineering Sciences at the University of Southampton have shown that the impact of carbon dioxide is being felt in space too. view more (2005-04-18)
Forests Could Benefit When Fall Color Comes Late
Do those fall colors seem to show up later and later-if at all? Scientists say we can blame increasing amounts of carbon dioxide in the atmosphere for prolonging the growing season of the trees. And that may actually be good news for forestry industries. view more (2008-01-23)
Methane-eating microbes can use iron and manganese oxides to 'breathe'
Iron and manganese compounds, in addition to sulfate, may play an important role in converting methane to carbon dioxide and eventually carbonates in the Earth's oceans, according to a team of researchers looking at anaerobic sediments. view more (2009-07-10)
Global warming aided by drought, deforestation link
In the rainforests of equatorial Asia, a link between drought and deforestation is fueling global warming, finds an international study that includes a UC Irvine scientist. view more (2008-12-09)
Early Earth haze may have spurred life, says University of Colorado study
Hazy skies on early Earth could have provided a substantial source of organic material useful for emerging life on the planet. view more (2006-11-07)
A bumpy shift from ice house to greenhouse
The transition from an ice age to an ice-free planet 300 million years ago was highly unstable, marked by dips and rises in carbon dioxide, extreme swings in climate and drastic effects on tropical vegetation, according to a study published in the journal Science Jan. 5. view more (2007-01-05)
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)
Water at Martian south pole
Thanks to ESA's Mars Express, we now know that Mars has vast fields of perennial water ice, stretching out from the south pole of the Red Planet. Astronomers have known for years that Mars possessed polar ice caps, but early attempts at chemical analysis suggested only that the northern cap could be composed of water ice, and the southern cap... view more...

Scientists enhance Mother Nature's carbon handling mechanism
Taking a page from Nature herself, a team of researchers developed a method to enhance removal of carbon dioxide from the atmosphere and place it in the Earth's oceans for storage. view more (2007-11-07)
Researchers find new taste in fruit flies: carbonated water
That fruit fly hovering over your kitchen counter may be attracted to more than the bananas that are going brown; it may also want a sip of your carbonated water. view more (2007-08-30)
Carbon dioxide emissions predicted to reduce density of Earth's outermost atmosphere by 2017
Carbon dioxide emissions from the burning of fossil fuels will produce a 3 percent reduction in the density of Earth's outermost atmosphere by 2017, according to a team of scientists from the National Center for Atmospheric Research (NCAR) and Pennsylvania State University (PSU). view more (2006-12-12)
Climate change following collapse of the Maya empire
Researchers from the University of Amsterdam have demonstrated that the climate in South Mexico changed following the collapse of the Maya empire. From preserved pollen grains the paleoecologists could deduce that the climate quickly became dryer. The climate becoming dryer, explains the decrease in the population following the collapse of the... view more... (2002-01-29)
Smell experience during critical period alters brain
Unlike the circuitry of the visual system, that of the olfactory system was thought to be hardwired: Once the neurons had formed, no amount of sensory input could change their arrangement. view more (2007-12-06)
Modest CO2 cutbacks may be too little, too late for coral reefs
How much carbon dioxide is too much? According to United Nations Framework Convention on Climate Change (UNFCCC) greenhouse gases in the atmosphere need to be stabilized at levels low enough to "prevent dangerous anthropogenic interference with the climate system." But scientists have come to realize that an even more acute danger than... view more... (2008-09-23)
Greenhouse ocean may downsize fish
By 2100, warmer oceans with more carbon dioxide may no longer sustain 1 of the world's most productive fisheries, says USC marine ecologist. view more (2008-01-14)
Sunlight turns carbon dioxide to methane
Dual catalysts may be the key to efficiently turning carbon dioxide and water vapor into methane and other hydrocarbons using titania nanotubes and solar power, according to Penn State researchers. view more (2009-03-05)
Nitrous oxide from ocean microbes
A large amount of the greenhouse gas nitrous oxide is produced by bacteria in the oxygen poor parts of the ocean using nitrites, Dr Mark Trimmer told journalists at a Science Media Centre press briefing today. view more (2007-12-11)
