We Owe It All to Comets
Comets have always fascinated us. A mysterious appearance could symbolize God's displeasure or mean a sure failure in battle, at least for one side. view more (2009-04-29)
First-ever study to link increased mortality specifically to carbon dioxide emissions
A Stanford scientist has spelled out for the first time the direct links between increased levels of carbon dioxide in the atmosphere and increases in human mortality, using a state-of-the-art computer model of the atmosphere that incorporates scores of physical and chemical environmental processes. view more (2008-01-04)
Keeping slim is good for the planet, say scientists
Maintaining a healthy body weight is good news for the environment, according to a study which appears today in the International Journal of Epidemiology. view more (2009-04-20)
Invisible gases form most organic haze in urban, rural areas
A new study involving the University of Colorado at Boulder shows that invisible, reactive gases hovering over Earth's surface, not direct emissions of particulates, form the bulk of organic haze in both urban and rural areas around the world. view more (2007-07-10)
Putting a green cap on garbage dumps
andfill sites produce the greenhouse gases, methane and carbon dioxide, as putrescible waste decays. Growing plants and trees on top of a landfill, a process known as 'Phytocapping', could reduce the production and release of these gases, according to Australian scientists writing in a forthcoming issue of International Journal of Environmental... view more...

Researchers identify energy gains and environmental impacts of corn ethanol and soybean biodiesel
The first comprehensive analysis of the full life cycles of soybean biodiesel and corn grain ethanol shows that biodiesel has much less of an impact on the environment and a much higher net energy benefit than corn ethanol, but that neither can do much to meet U.S. energy demand. view more (2006-07-12)
Studies of ancient climates suggest Earth is now on a fast track to global warming
Human activities are releasing greenhouse gases more than 30 times faster than the rate of emissions that triggered a period of extreme global warming in the Earth's past, according to an expert on ancient climates. view more (2006-02-17)
Lucky find off Galapagos
During an expedition off the South American coast, an international team of ocean scientists discovered that the gases ethane and propane are widespread, and are being produced by microorganisms in deeply buried sediments. view more (2006-09-22)
Argon conclusion: Researchers reassess theories on formation of Earth's atmosphere
Geochemists at Rensselaer Polytechnic Institute are challenging commonly held ideas about how gases are expelled from the Earth. Their theory, which is described in the Sept. 20 issue of the journal Nature, could change the way scientists view the formation of Earth's atmosphere and those of our distant neighbors, Mars and Venus. view more (2007-09-20)
Climate change -- research suggests it is not a swindle
New research has dealt a blow to the skeptics who argue that climate change is all due to cosmic rays rather than to man-made greenhouse gases. The new evidence shows no reliable connection between the cosmic ray intensity and cloud cover. view more (2008-04-03)
Arctic sea ice decline may trigger climate change cascade, says University of Colorado study
Arctic sea ice that has been dwindling for several decades may have reached a tipping point that could trigger a cascade of climate change reaching into Earth's temperate regions, says a new University of Colorado at Boulder study. view more (2007-03-16)
Compost can turn agricultural soils into a carbon sink, thus protecting against climate change
Applying organic fertilizers, such as those resulting from composting, to agricultural land could increase the amount of carbon stored in these soils and contribute significantly to the reduction of greenhouse gas emissions. view more (2008-02-25)
New Noble Gas Chemical Compounds Created As Result Of Hebrew University Research
Chemical compounds consisting of noble gases combined with hydrocarbon molecules - a feat previously thought to be unattainable - have been created as the result of the work of researchers at the Hebrew University of Jerusalem. view more (2005-03-23)
Volcanic eruptions, ancient global warming linked
A team of scientists announced today confirmation of a link between massive volcanic eruptions along the east coast of Greenland and in the western British Isles about 55 million years ago and a period of global warming that raised sea surface temperatures by five degrees (Celsius) in the tropics and more than six degrees in the Arctic. view more (2007-04-27)
Lower increases in global temps could lead to greater impacts than previously thought, study finds
A new study by scientists updating some of the findings of the Intergovernmental Panel on Climate Change (IPCC) 2001 Third Assessment Report finds that even a lower level of increase in average global temperatures due to greenhouse gas emissions could cause significant problems in five key areas of global concern. view more (2009-02-24)
Caltech scientists predict greater longevity for planets with life
Roughly a billion years from now, the ever-increasing radiation from the sun will have heated Earth into inhabitability; the carbon dioxide in the atmosphere that serves as food for plant life will disappear, pulled out by the weathering of rocks; the oceans will evaporate; and all living things will disappear. view more (2009-06-15)
MU Scientist Uses Tracer to Predict Ancient Ocean Circulation
Even though the Cretaceous Period ended more than 65 million years ago, clues remain about how the ocean water circulated at that time. view more (2008-10-21)
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)
Warming climate may cause arctic tundra to burn
Research from ancient sediment cores indicates that a warming climate could make the world's arctic tundra far more susceptible to fires than previously thought. view more (2008-03-05)
Have you run out of energy?
Imagine having your own annual greenhouse gas allowance which you 'spend' each time you fill up with petrol or pay an electric or gas bill. It sounds like a scene from a futuristic movie, but this scenario could really happen in the next few years according to researchers at the UK's Tyndall Centre for Climate Change Prediction. view more (2004-09-20)
