Carbon sinks: Issues, markets, policy
With reducing carbon emissions on the national agenda, a group of expert panelists will discuss methods, markets, testing and policy issues on how carbon sinks or carbon sequestration may be used to reduce atmospheric CO2.   view more (2008-09-29)

Crystal sponges excel at sopping up CO2
Since the Industrial Revolution, levels of carbon dioxide--a major contributor to the greenhouse effect--have been on the rise, prompting scientists to search for ways of counteracting the trend.   view more (2005-12-02)

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)

Carbon dioxide role in past climate revealed
Researchers at the British Antarctic Survey (BAS) and the University of California, Santa Cruz have discovered that Earth's last great global warming period, 3 million years ago, may have been caused by levels of CO2 in the atmosphere similar to today's.   view more (2005-04-11)

The origin of perennial water-ice at the South Pole of Mars
Thanks to data from ESA's Mars Express mission, combined with models of the Martian climate, scientists can now suggest how the orbit of Mars around the Sun affects the deposition of water ice at the Martian South Pole.   view more (2007-07-16)

Amazon outflow is found to power ocean capture of carbon dioxide
Nutrients washed out of the Amazon River are powering huge amounts of previously unexpected plant life far out to sea, thus trapping atmospheric carbon dioxide, according to a new study.   view more (2008-07-24)

MIT: A quicker, easier way to make coal cleaner
Construction of new coal-fired power plants in the United States is in danger of coming to a standstill, partly due to the high cost of the requirement - whether existing or anticipated - to capture all emissions of carbon dioxide, an important greenhouse gas.   view more (2008-11-18)

Biodiesel won't drive down global warming
EU legislation to promote the uptake of biodiesel will not make any difference to global warming, and could potentially result in greater emissions of greenhouse gases than from conventional petroleum derived diesel.   view more (2007-04-23)

Ancient climate change may portend toasty future
Scientists, including Ken Caldeira of the Carnegie Institution's Department of Global Ecology, have found that the Earth's global warming, 55 million years ago, may have resulted from the climate's high sensitivity to a long-term release of carbon.   view more (2006-12-08)

Emission reduction assumptions for carbon dioxide overly optimistic, study says
Reducing global emissions of carbon dioxide (CO2) over the coming century will be more challenging than society has been led to believe, according to a new research commentary appearing April 3 in Nature.   view more (2008-04-03)

Storing carbon dioxide below ground may prevent polluting above
A new analysis led by an MIT scientist describes a mechanism for capturing carbon dioxide emissions from a power plant and injecting the gas into the ground, where it would be trapped naturally as tiny bubbles and safely stored in briny porous rock.   view more (2007-02-12)

Declining snowpack cools off CO2 emissions from winter soils, says U. of Colorado study
A recent decrease in Rocky Mountain snowpack has slowed the release of heat-trapping carbon dioxide gases from forest soils into the atmosphere during the dead of winter.   view more (2006-02-09)

Ice clouds put Mars in the shade
Until now, Mars has generally been regarded as a desert world, where a visiting astronaut would be surprised to see clouds scudding across the orange sky. However, new results show that the arid planet possesses high-level clouds that are sufficiently dense to cast a shadow on the surface.   view more (2008-01-17)

Kyoto climate commitments - a challenge for UK energy policy, say Academies
The report examines options for generating electricity without emission of CO2. These include using renewable sources (such as wind and solar) and negating CO2 emissions by use of 'carbon sequestration', as well as maintaining a nuclear energy capability.   view more (1999-06-14)

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... view more (1999-06-08)

Study Sheds Light on Earth's CO2 Cycles, Possible Impacts of Climate Change
A research team, including Kent State Professor of Geology Dr. Joseph Ortiz, tracing the origin of the large carbon dioxide increase in Earth's atmosphere at the end of the last ice age has detected two ancient "burps" that originated from the deepest parts of the southern ocean around... view more (2007-05-14)

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)

Experiments examine hydrogen-production benefits of clean coal burning
Sandia National Laboratories researchers here are studying the burning characteristics of coal to prepare the way for the coming of a hydrogen economy.   view more (2006-04-05)

Insomnia in parents can result in sleep problems, suicidal behavior among their offspring
A history of chronic insomnia in parents is not only associated with elevated risk for insomnia but also with elevated risks for use of hypnotics, psychopathology and suicidal behavior in adolescent offspring, according to a research abstract that will be presented on Thursday at SLEEP 2008, the... view more (2008-06-12)

High flyers are the scourge of the skies

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)

Rocks could be harnessed to sponge vast amounts of CO2 from air, says study
Scientists say that a type of rock found at or near the surface in the Mideast nation of Oman and other areas around the world could be harnessed to soak up huge quantities of globe-warming carbon dioxide.   view more (2008-11-06)

Engineered weathering process could mitigate global warming
Researchers at Harvard University and Pennsylvania State University have invented a technology, inspired by nature, to reduce the accumulation of atmospheric carbon dioxide (CO2) caused by human emissions.   view more (2007-11-08)

Ocean acidification -- another undesired side effect of fossil fuel-burning
Up to now, the oceans have buffered climate change considerably by absorbing almost one third of the worldwide emitted carbon dioxide. The oceans represent a significant carbon sink, but the uptake of excess CO2 stemming from man's burning of fossil fuels comes at a high cost: ocean acidification.   view more (2008-05-22)

Low-cost reusable material could facilitate capture of carbon dioxide from power plants
Researchers have developed a new, low-cost material for capturing carbon dioxide (CO2) from the smokestacks of coal-fired power plants and other generators of the greenhouse gas.
