Gas from the past gives scientists new insights into climate and the oceans
In recent years, public discussion of climate change has included concerns that increased levels of carbon dioxide will contribute to global warming, which in turn may change the circulation in the earth's oceans, with potentially disastrous consequences.   view more (2008-10-06)

World needs climate emergency backup plan, says expert
In submitted testimony to the British Parliament, climate scientist Ken Caldeira of the Carnegie Institution said that while steep cuts in carbon emissions are essential to stabilizing global climate, there also needs to be a backup plan.   view more (2008-11-10)

Parachuting allows krill to eat and run
Antarctic researchers have recorded a novel behavior in krill that may help regulate greenhouse gases. Antarctic krill, one of the largest animal resources on Earth, parachute into the deeper layers of the ocean many times a night and sequester large amounts carbon in the process.   view more (2006-02-07)

Metal Fibers Baked To Make Filters
In automotive catalytic converters and industrial exhaust gas filters, porous materials play a crucial role: they filter and break down hot waste gases. It is now possible to process virtually all metal alloys into fibers which can be used to make open-pored sintered materials. The requirements to... view more (2004-07-08)

Ozone recovering, but unlikely to stabilize at pre-1980 levels, says study
While Earth's ozone layer is slowly being replenished following an international 1987 agreement banning CFCs, the recovery is occurring in a changing atmosphere and is unlikely to stabilize at pre-1980 levels.   view more (2006-05-04)

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)

New JILA technique reveals hidden properties of ultracold atomic gases
Physicists at JILA, a joint institute of the National Institute of Standards and Technology (NIST) and the University of Colorado at Boulder, have demonstrated a powerful new technique that reveals hidden properties of ultracold atomic gases.   view more (2008-08-07)

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)

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... view more (2008-11-24)

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)

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)

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)

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)

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... view more (2007-09-20)

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... view more (2007-04-27)

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)

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)

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... view more (2004-09-20)

Before selling carbon credits, read this
Storing carbon in agricultural soils presents an immediate option to reduce atmospheric carbon dioxide and slow global warming.   view more (2007-05-21)

Collapse of Antarctic Ice Shelf Unprecedented
The Antarctic Peninsula is undergoing greater warming than almost anywhere on Earth, a condition perhaps associated with human-induced greenhouse effects.   view more (2005-08-04)

International Field Campaign examines impact of beetle kill on Rocky Mountain weather, air quality
Mountain pine beetles appear to be doing more than killing large swaths of forests in the Rocky Mountains. Scientists suspect they are also altering local weather patterns and air quality.   view more (2008-09-25)
