Global warming of the future is projected by ancient carbon emissions
Global warming 55 million years ago suggests a high climate sensitivity to carbon dioxide, according to research led by Mark Pagani, associate professor of geology and geophysics at Yale and published in the December 8 issue of Science. view more (2006-12-08)
Food source threatened by carbon dioxide
Carbon dioxide increasing in the atmosphere may affect the microbial life in the sea, which could have an impact on a major food source, warned Dr Ian Joint at a Science Media Centre press briefing today. view more (2007-12-11)
North Sea efficient sink for carbon dioxide
The measured annual increase in the concentration of carbon dioxide (CO2) in the atmosphere is only 60 percent of the annual emissions from fossil fuels. view more (2005-10-11)
Carbon dioxide and climate - the plot thickens
Using a novel technique, the researchers obtained a best estimate for carbon dioxide levels 43 million years ago of 385 parts per million (ppm), slightly higher than today's figure of 360 ppm. This result is far below earlier estimates which suggested that carbon dioxide levels were up to six times present day values. There are two ways to... view more... (1999-06-08)
Dried distiller's grains can help produce more beef
Supplemental feeding of dried distiller's grains to cattle can help produce more beef in grazing programs, a Texas Agricultural Experiment Station researcher said. view more (2007-01-05)

Fuel Emissions From Marine Vessels Remain a Global Concern
Marine vessels are no longer resting in a safe harbor. The forecast for clear skies and smooth sailing for oceanic vessels has been impeded by worldwide concerns of their significant contributions to air pollution and greenhouse gas emissions that impact the Earth's climate. view more (2008-09-10)
Cleaning up pollutants with sunlight
A cheap, harmless chemical and sunlight could provide an environmentally friendly way of destroying micro-pollutants in the environment. UK researchers are developing a new type of reactor to destroy persistent contaminants such as pesticides and pharmaceutical residues. The technology, which breaks down the polluting molecules into carbon... view more... (2002-10-23)
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)
Russian Filter For Russian Exhausts
Automobiles manufactured in Russia are now often equipped with expensive American or European catalytic exhaust scrubbers - converters. However, according the opinion of researchers from the Mendeleyev Russian Chemical-Engineering University, Russian automobiles will be soon equipped with exhaust scrubbers manufactured in Russia. Traditional... view more... (2004-06-15)
New model revises estimates of terrestrial carbon dioxide uptake
Researchers at the University of Illinois have developed a new model of global carbon and nitrogen cycling that will fundamentally transform the understanding of how plants and soils interact with a changing atmosphere and climate. view more (2007-12-12)
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)
Beneficial effects of no-till farming depend upon future climate change
By storing carbon in their fields through no-till farming practice, farmers can help countries meet targeted reductions in atmospheric carbon dioxide and reduce the harmful effects of global warming. view more (2005-10-13)
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 into the atmosphere as carbon dioxide. This will... view more... (2005-05-05)
Chemical coffee maker promises purer medicines
Their method uses pressurised carbon dioxide as a solvent, because it allows chemical reactions which usually create a mixture of products to produce only one. Project leaders Chris Rayner and Tony Clifford believe it could change the way pharmaceuticals are manufactured in the future. "If the effect is general for a wide range of chemical... view more...

Corals and Climate Change
A modest new lab at the Rosenstiel School is the first of its kind to tackle the global problem of climate change impacts on corals. view more (2007-08-23)
NORTH ATLANTIC SLOWS DOWN THE GREENHOUSE-EFFECT
What sounds to us like bookkeeping of global change and tedious science, has a big meaning for our climate future. After all, traffic and industrial plants in Europe and North America play a particularly large role in the carbon dioxide pollution of the atmosphere and the greenhouse-effect resulting from it. The processes in the North Atlantic... view more... (1999-06-08)
Asthmatic children in multi-family housing hit by indoor nitrogen dioxide
Children with asthma living in multi-family housing who are exposed to certain levels of indoor nitrogen dioxide, a poisonous pollutant byproduct of gas stoves and unvented heaters, are more likely to experience wheeze, persistent cough, shortness of breath and chest tightness. view more (2006-02-01)
Strengthening case for life on Mars - CMD19CMMP with The Physics Congress 2002
When it was announced last month that the Mars Odyssey satellite had found water ice beneath the planet`s frozen carbon dioxide south polar ice cap, "I felt excited!" says Dr Lidija Siller, a physicist from the University of Newcastle. "I believe that the data I have explains how this water became trapped underneath the surface". Dr Siller will be... view more... (2002-03-26)
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)
