Massive greenhouse gases may be released as destruction, drying of world wetlands worsens: UN
Leading world scientists convene in Brazil July 21-25 amid growing concern that evaporation and ongoing destruction of world wetlands, which hold a volume of carbon similar to that in the atmosphere today, could cause them to exhale billows of greenhouse gases. view more (2008-07-21)
Underground Nuclear Explosions Deteriorate The Ozone Layer
Russian scientists have found one more cause of depletion of the ozone layer. They think that abyssal gases can go to the surface and reach stratosphere, deteriorating the ozone shield. Underground nuclear explosions enforce this process. A geologist Boris Golubov of the Institute of Geosphere Dynamics RAS and a climatologist Grigoriy Kruchenitsky... view more... (2002-08-16)
Bad sign for global warming: Thawing permafrost holds vast carbon pool
Permafrost blanketing the northern hemisphere contains more than twice the amount of carbon in the atmosphere, making it a potentially mammoth contributor to global climate change depending on how quickly it thaws. view more (2008-09-04)
Laughing Gas in a Vicious Circle
Italian researchers discover another mechanism for the formation of atmospheric N2O Summer smog, the ozone hole, the greenhouse effect – the complex web of chemical reactions in the atmosphere, which leads to manifold environmental problems, is still not fully cleared up. In a tricky way, a single chemical compound is found at the center of... view more... (2001-05-15)
NASA Study Links "Smog" to Arctic Warming
NASA scientists have found that a major form of global air pollution involved in summertime "smog" has also played a significant role in warming the Arctic. view more (2006-03-15)
CO2 emissions booming, shifting east, researchers report
Despite widespread concern about climate change, annual carbon dioxide emissions from burning fossil fuels and manufacturing cement have grown 38 percent since 1992, from 6.1 billion tons of carbon to 8.5 billion tons in 2007. view more (2008-09-25)
Plan to conserve forests may be detrimental to other ecosystems
Conserving biodiversity must be considered when developing plans to reduce greenhouse gas emissions from deforestation, researchers warn in today's edition of Science. view more (2008-06-13)
Study gives clearer picture of how land-use changes affect U.S. climate
Researchers say regional surface temperatures can be affected by land use, suggesting that local and regional strategies, such as creating green spaces and buffer zones in and around urban areas, could be a tool in addressing climate change. view more (2009-11-04)
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 be met by a coffee filter are simple: it must... view more... (2004-07-08)
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)
Computer models show major climate shift as a result of closing ozone hole
A new study led by Columbia University researchers has found that the closing of the ozone hole, which is projected to occur sometime in the second half of the 21st century, may significantly affect climate change in the Southern Hemisphere, and therefore, the global climate. view more (2008-06-13)
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)
Clouds: Lighter than air but laden with lead
By sampling clouds -- and making their own -- researchers have shown for the first time a direct relation between lead in the sky and the formation of ice crystals that foster clouds. view more (2009-04-20)
New insights into the 'smell of death' could help recover bodies in disasters and solve crimes
In an advance toward the first portable device for detecting human bodies buried in disasters and at crime scenes, scientists today report early results from a project to establish the chemical fingerprint of death. view more (2009-08-17)
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)
34 US Nobel Laureates urge inclusion of $150 billion in climate legislation
A group of 34 U.S. Nobel Laureates is calling on President Obama to urge Congress to include the president's proposed $150 billion Clean Energy Technology Fund in the climate legislation it is considering. view more (2009-07-17)
Detecting disease in greenhouse plants
Greenhouses are an integral part of U.S. agriculture. Nearly $200 million of food is produced in domestic greenhouses each year, and the facilities play a vital role in producing seeds and transplantable vegetation. Understanding how to keep greenhouse plants healthy can translate to increased revenue for producers. view more (2009-02-18)
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)
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)
11 leading national experts reach consensus on beneficial biofuels
"Done right," biofuels can be produced in large quantities and have multiple benefits, but only if they come from feedstocks produced with low life-cycle greenhouse gas emissions, as well as minimal competition with food production. view more (2009-07-17)
