Why is Greenland covered in ice?
There have been many reports in the media about the effects of global warming on the Greenland ice-sheet, but there is still great uncertainty as to why there is an ice-sheet there at all.   view more (2008-08-28)

Tropical rainforest nutrients linked to global carbon dioxide levels
Extra amounts of key nutrients in tropical rain forest soils cause them to release more carbon dioxide into the atmosphere, according to research conducted by scientists at the University of Colorado (CU)—Boulder.   view more (2006-06-21)

NIST develops rapid method for judging nanotube purity
Researchers at the National Institute of Standards and Technology (NIST) have developed a sensitive new method for rapidly assessing the quality of carbon nanotubes.   view more (2007-02-02)

Warming could free far more carbon from high Arctic soil than earlier thought
Scientists studying the effects of carbon on climate warming are very likely underestimating, by a vast amount, how much soil carbon is available in the high Arctic to be released into the atmosphere, new University of Washington research shows.   view more (2005-12-06)

White Christmases unlikely
CRed, the community carbon reduction project run out of the University of East Anglia, is urging people to aim for a low carbon Christmas this year. CRed say that the reason we no longer have any White Christmases is down to global warming and that we need to work harder at reducing our carbon... view more (2003-12-03)

Woods Hole Research Center scientist furthering discussion of soil carbon decomposition
Significantly more carbon is stored in the world's soils than is present in the atmosphere. In a process called a "positive feedback," global warming may stimulate decomposition of soil organic matter, thus releasing heat-trapping carbon dioxide gas to the atmosphere, possibly causing the... view more (2006-03-09)

Spin control: New technique sorts nanotubes by length
Researchers at the National Institute of Standards and Technology (NIST) have reported a new technique to sort batches of carbon nanotubes by length using high-speed centrifuges.   view more (2008-05-19)

UniS' nanotechnology expertise on show at Science Museum
The University of Surrey's world-class expertise in nanotechnology research is a key contributor to a new exhibition entitled 'Nanotechnology: small science‚ big deal', now showing at the Science Museum in London. Professor Ravi Silva, from the University's Advanced Technology Institute... view more (2005-03-09)

Dust threatens Kyoto protocol
On the eve of the Earth Summit in Johannesburg, scientists at UCL have detected a flaw in the Kyoto protocol`s global plans to reduce the impact of global warming, all because of something as simple as atmospheric dust. Dr Mark Maslin of UCL`s Environmental Change Research Centre explains: "Dust is... view more (2002-08-07)

Forests' long-term potential for carbon offsetting
As well as cutting our fossil fuel emissions, planting new forests, or managing existing forests or agricultural land more effectively can capitalise on nature's ability to act as a carbon sink.   view more (2008-04-15)

Using an activated-carbon filtering pitcher significantly reduces chemicals in tap water
A study conducted by Université Laval researchers concludes that using an activated-carbon filtering pitcher is the most effective way to reduce disinfection by-products in tap water.   view more (2006-11-03)

Rising surface ozone reduces plant growth and adds to global warming
Scientists from three leading UK research institutes have today released new findings that could have major implications for food production and global warming in the 21st century.   view more (2007-07-26)

Methane doesn't necessarily mean life on Mars, says Dartmouth study
Two Dartmouth researchers have weighed in on the debate over whether the presence of methane gas on Mars indicates life on the red planet. Mukul Sharma, Assistant Professor of Earth Sciences, and Chris Oze, a postdoctoral fellow, argue that the Martian methane could have been produced by inorganic... view more (2005-06-08)

Carbon-based quantum dots could mean 'greener' safer technology in medicine and biology
Chemists at Clemson University say they have developed a new type of quantum dot that is the first to be made from carbon.   view more (2006-05-24)

Sinking Greenhouse Gases into the Ocean
"Polarstern" begins new iron fertilization experiment On January 21, 2004, the "Polarstern", research vessel of the Alfred-Wegener-Institute of Polar and Marine Research, will leave Cape Town for the third stage of the 21st expedition to Antarctica. Forty-nine scientists from nine countries... view more (2004-01-21)

Global warming predicted to hasten carbon release from peat bogs
Billions of tons of carbon sequestered in the world's peat bogs could be released into the atmosphere in the coming decades as a result of global warming, according to a new analysis of the interplay between peat bogs, water tables, and climate change.   view more (2008-11-07)

Electrical conductivity of carbon nano-tubes
Pb. 2000/38 Delft, 19 april 2000 EMBARGO TOT 19 APRIL 2000, 20.00 UUR Fundamentally new view on electrical conductivity of carbon nano-tubes described in Nature Molecular electrical conductivity unexpectedly different at nano-level The electric charge in a semi-conductive carbon nano-tube of... view more (2000-04-20)

Perfecting a solar cell by adding imperfections
Nanotechnology is paving the way toward improved solar cells. New research shows that a film of carbon nanotubes may be able to replace two of the layers normally used in a solar cell, with improved performance at a lower cost. Researchers have found a surprising way to give the nanotubes the... view more (2008-06-17)

Argonne scientists discover networks of metal nanoparticles are culprits in alloy corrosion
Oxide scales are supposed to protect alloys from extensive corrosion, but scientists at U.S. Department of Energy's Argonne National Laboratory have discovered metal nanoparticle chinks in this armor.   view more (2008-08-05)

A link between greenhouse gases and the evolution of C4 grasses
How a changing climate can affect ecosystems is an important and timely question, especially considering the recent global rise in greenhouse gases.   view more (2007-12-21)

Storage of greenhouse gasses in Siberian peat moor
Wet peat moorlands form a sustainable storage place for the greenhouse gas carbon dioxide but are also a source of the much stronger greenhouse gas methane. According to Dutch researcher Wiebe Borren, peat moorlands will counteract the greenhouse effect under the present climatic conditions.   view more (2007-01-31)

Northern forests less effective than tropical forests in reducing global warming
Forests in the United States and other northern mid- and upper-latitude regions are playing a smaller role in offsetting global warming than previously thought, according to a study appearing in this week's issue of Science.   view more (2007-06-25)

Building blocks of the future
Structure and properties of carbon nanostructures The discovery in 1985 of fullerenes, tiny carbon balls of nanometer dimensions, ushered in a new era in international science. Only a few years later (1991) scientific interest also started to focus on so-called carbon nanotubes. The discovery of... view more (2002-12-05)

US faces burning emissions issue
Severe United States wildfires can contribute as much as vehicles to carbon emissions in some US states, although the amount is highly variable.   view more (2007-11-01)
