65-million-year-old asteroid impact triggered a global hail of carbon beads
The asteroid presumed to have wiped out the dinosaurs struck the Earth with such force that carbon deep in the Earth's crust liquefied, rocketed skyward, and formed tiny airborne beads that blanketed the planet.   view more (2008-05-06)

Increased atmospheric carbon dioxide promotes algal growth
It is usually thought that unlike terrestrial plants, submerged plants like algae will not show any response to an increase of atmospheric carbon dioxide. This view may be biased by a neglect of the effects of the plants themselves on the water chemistry. In the June issue of Ecology Letters,... view more (2004-05-13)

First-ever 'State of the Carbon Cycle Report' finds troubling imbalance
The first "State of the Carbon Cycle Report" for North America, released online this week by the U.S. Climate Change Science Program, finds the continent's carbon budget increasingly overwhelmed by human-caused emissions.   view more (2007-11-15)

Global warming plus natural bacteria could release vast carbon deposits currently stored in Arctic soil
Increasing concentrations of carbon dioxide in the atmosphere will make global temperatures rise. By studying soil cores from the Arctic, scientists have discovered that this rise in temperature stimulates the growth of microorganisms that can break down long-term stores of carbon, releasing them... view more (2005-05-05)

Global warming may not have ended Ice-Age, says research
Scientists at the University of Sheffield have used fossilised leaves to determine the effect of greenhouse gases on the end of the Ice Age 300m years ago, according to an article published in PNAS. The study, led by Professor David Beerling, examined fossilised leaves to determine how much carbon... view more (2002-09-12)

Loose grip
Carbon dioxide (CO2) is contained in the air we exhale, and is also always formed when carbon-containing substances such as oil, gas, wood, and plastics are burned - it is omnipres-ent. Chemists have long been trying to convert this gas to something useful, and Koji Tanaka and coworkers from the... view more (1999-01-28)

Invititation to the Media - Soils as carbon sinks-a breathing space in the race against global warming?
Can we use land carbon sinks as a way to buy time for the restructuring of our energy generation? "We estimate soil carbon sinks could mitigate 8% of the EU`s emissions if major changes were made in land use and agricultural management ," says Professor David Powlson of IACR Rothamsted. However;... view more (2002-06-26)

Understanding the global carbon budget -- Woods Hole Research Center expert provides insights
As climate change becomes more and more a central issue in local, national, and international discussions, understanding the global carbon budget, and how it influences trends in global warming, will become increasingly crucial.   view more (2007-05-10)

Carbon sink capacity in northern forests reduced by global warming
An international study investigating the carbon sink capacity of northern terrestrial ecosystems discovered that the duration of the net carbon uptake period (CUP) has on average decreased due to warmer autumn temperatures.   view more (2008-01-03)

Forests - just how absorbing are they?
Forests form an integral part of the Kyoto Protocol on climate change because they act as terrestrial "sinks" to soak up the carbon emissions that are contributing to global warming. Countries that have ratified the protocol can offset their carbon emissions quota by planting trees,... view more (2003-03-13)

Higher carbon dioxide, lack of nitrogen limit plant growth
Earth's plant life will not be able to "store" excess carbon from rising atmospheric carbon dioxide levels as well as scientists once thought because plants likely cannot get enough nutrients, such as nitrogen, when there are higher levels of carbon dioxide   view more (2006-04-13)

Confirmed - deforestation plays critical climate change role
Dr Pep Canadell, from the Global Carbon Project and CSIRO Marine and Atmospheric Research, says today in the journal Science that tropical deforestation releases 1.5 billion tonnes of carbon each year into the atmosphere.   view more (2007-05-14)

Increased environmental carbon levels - the good news!
Increasing carbon levels can be a good thing in some cases: scientists at the University of Durham propose that higher levels of inorganic carbon can have a positive influence on human health.   view more (2006-04-03)

Methane from microbes: a fuel for the future
Microbes could provide a clean, renewable energy source and use up carbon dioxide in the process, suggested Dr James Chong at a Science Media Centre press briefing today.   view more (2007-12-11)

Emissions irrelevant to future climate change?
Climate change and the carbon emissions seem inextricably linked. However, new research published in BioMed Central's open access journal Carbon Balance and Management suggests that this may not always hold true, although it may be some time before we reach this saturation point.   view more (2008-04-28)

Role of Silica in Climate Cycles
New research from the University of East Anglia (UEA) has demonstrated that the compound silica was not solely responsible for changes in carbon dioxide levels during past Ice Ages. It is already known from scientific research that during past Ice Ages increased amounts of silica, a common... view more (2001-06-21)

Carbon offset warning from international team of scientists
Leading marine scientists from across the world have issued a warning that it is too early to sell carbon offsets from ocean iron fertilisation.   view more (2008-01-11)

UA scientists part of Supreme Court case on carbon dioxide emissions
Four faculty members from The University of Arizona in Tucson were part of an amicus curiae brief supporting the plaintiff in today's historic U.S. Supreme Court decision on carbon dioxide emissions and climate change.   view more (2007-04-03)

Improved wettability of carbon nanotubes opens the door to new possibilities
Carbon nanotubes have long been touted as the wonder material of the future but their wonder properties can also be their downfall. The non reactive nature of carbon nanotubes means they can be difficult to incorporate into other materials for real world applications.   view more (2007-11-26)

Carbon turns over much faster through basal food-chain levels in aquatic than in terrestrial ecosystems
Global temperatures have increased dramatically over the past century, which is causing major impacts on climate patterns, ocean circulation and wildlife preservation. The increase in temperature is largely due to a rise of anthropogenic emissions of greenhouse gases, of which CO2 is one of the... view more (2004-02-25)

Another type of nanotube, a how-to guide to making bamboo-structured carbon nanotubes
Nanotechnology is area if science that has recently captured the attention of people all around the world. At the heart of the nanotechnology revolution are carbon nanotubes, amazing materials with astonishing properties. They have applications in most fields, with new possibilities emerging... view more (2007-11-26)

High Value Semiconducting Carbon Nanotubes
Moore's Law states that the number of transistors on a chip doubles every eighteen months. However current silicon technologies are approaching the limits imposed by quantum mechanics, which will stop Moore's Law in its tracks within 20 years. New materials and techniques must be found to... view more (2004-07-09)
