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)

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)

Emissions rising faster this decade than last
The latest figures on the global carbon budget to be released in Washington and Paris today indicate a four-fold increase in growth rate of human-generated carbon dioxide emissions since 2000.   view more (2008-10-02)

CO2 emissions increasing faster than expected
Carbon dioxide emissions from fossil fuels - the principal driver of climate change - have accelerated globally at a far greater rate than expected over recent years.   view more (2007-05-22)

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)

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)

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)

Agricultural soil erosion not contributing to global warming, study shows
Agricultural soil erosion is not a source of carbon dioxide to the atmosphere, according to research published online in Science.   view more (2007-10-26)

Growth in the global carbon budget
Today the new Global Carbon Budget was launched simultaneously by Global Carbon Project co-chair Michael Raupach in France at the Paris Observatory, and in the USA at Capitol Hill, Washington by GCP Executive Director Pep Canadell.   view more (2008-09-25)

Decline in uptake of carbon emissions confirmed
A decline in the proportion of carbon dioxide (CO2) emissions absorbed by land and oceans is speeding up the growth of atmospheric CO2, according to a paper published today in the US Journal: Proceedings of the National Academy of Science.   view more (2007-10-25)

Carnegie Mellon urges industry to broaden carbon footprint calculations
Carnegie Mellon University researchers are urging companies to embrace new methods for following the trail of dangerous carbon emissions that are responsible for much of the world's global warming threats.   view more (2008-08-18)

Climate protocol may save Amazon region
If Brazil gets a climate protocol, like the Kyoto Protocol for the rich countries, it will be possible to create an incentive for the country to reduce the deforestation of the Amazon region. The Kyoto Protocol targets a reduction of emissions of carbon dioxide and greenhouse gases. In a new... view more (2004-05-28)

KTH research: Increased combustion reduces carbon dioxide emissions
New, previously overlooked technology could dramatically reduce emissions of carbon dioxide. Bio-energy facilities that capture carbon dioxide from combustion gases would even make it possible to reduce the amount of carbon dioxide in the atmosphere. The idea of capturing carbon dioxide and storing... view more (2001-11-23)

Rise in atmospheric CO2 accelerates as economy grows, natural carbon sinks weaken
Human activities are releasing carbon dioxide faster than ever, while the natural processes that normally slow its build up in the atmosphere appear to be weakening.   view more (2007-10-23)

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)

Carnegie Mellon researchers to curb CO2 emissions
Carnegie Mellon University's Chris T. Hendrickson and H. Scott Matthews along with Alex Carpenter and Heather MacLean of the University of Toronto challenge Canadian officials to take the lead in eliminating dangerous carbon dioxide emissions that fuel global warming.   view more (2008-04-03)

Learning to trade in carbon dioxide
"You have to be well prepared to enter the emissions trading arena. Otherwise you'll run the same financial risks as on a conventional stock exchange," declares Franzjosef Schafhausen of the German ministry for the environment, who heads the working group on the national climate change... view more (2003-12-01)

Thawing permafrost likely to boost global warming
The thawing of permafrost in northern latitudes, which greatly increases microbial decomposition of carbon compounds in soil, will dominate other effects of warming in the region and could become a major force promoting the release of carbon dioxide and thus further warming, according to a new... view more (2008-09-02)

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)

Carnegie Mellon researchers urge development of low carbon electricity
Carnegie Mellon University's Constantine Samaras and Kyle Meisterling report that plug-in hybrid electric vehicles could help reduce greenhouse gas emissions that fuel global warming, but the benefits are highly dependent on how the electricity system changes in the coming decades.   view more (2008-04-28)

Childhood cancers strongly linked to air pollution in early life
Childhood cancers are strongly linked to pollution from engine exhausts, concludes research in the Journal of Epidemiology and Community Health.   view more (2005-08-11)

Ancient British bog provides clue to global warming
Analysis of sediments from a British bog suggest that methane emissions increased due to intense global warming around 55 million years ago.   view more (2007-09-20)

Reducing carbon emissions could help -- not harm -- US economy
A national policy to cut carbon emissions by as much as 40 percent over the next 20 years could still result in increased economic growth, according to an interactive website that reviews 25 of the leading economic models used to predict the economic impacts of reducing emissions.   view more (2008-03-20)

US fires release large amounts of carbon dioxide
Large-scale fires in a western or southeastern state can pump as much carbon dioxide into the atmosphere in a few weeks as the state's entire motor vehicle traffic does in a year.   view more (2007-11-01)

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)
