Scientists at Singapore's Institute of Bioengineering and Nanotechnology (IBN) have succeeded in unlocking the potential of carbon dioxide – a common greenhouse gas – by converting it into a more useful product.

A powerful greenhouse gas is at least four times more prevalent in the atmosphere than previously estimated, according to a team of researchers at Scripps Institution of Oceanography at UC San Diego.

Frozen arctic soil contains nearly twice the greenhouse-gas-producing organic material as was previously estimated, according to recently published research by University of Alaska Fairbanks scientists.

An abrupt release of methane, a powerful greenhouse gas, from ice sheets that extended to Earth's low latitudes some 635 million years ago caused a dramatic shift in climate, scientists funded by the National Science Foundation (NSF) report in this week's issue of the journal Nature.

Ice cores are essential for climate research, because they represent the only archive which allows direct measurements of atmospheric composition and greenhouse gas concentrations in the past. Using novel isotopic studies, scientists from the European Project for Ice Coring In Antarctica (EPICA) were now able to identify the most important processes responsible for changes in natural methane concentrations over the transition from the last ice age into our warm period.

Scientists and engineers in Georgia and Pennsylvania are reporting development of a new, low-cost material for capturing carbon dioxide from the smokestacks of coal-fired electric power plants and other industrial sources before the notorious greenhouse gas enters the atmosphere.

Farmers, food suppliers, policy-makers, business leaders and environmentalists are joining forces to confront the threat of the ‘forgotten greenhouse gas’ by taking part in an influential new forum at the University of East Anglia (UEA).

Ice core records from Antarctica and Greenland show greenhouse gas signatures consistent with climate inferences assumed from records of oxygen isotope fractions through time.

Officials from the world's 16 largest greenhouse gas emitters gathered in Hawaii this week to discuss how to curb global climate change. Kayla Rosenfeld reports from Honolulu the goal was to advance the road map created last year at the U.N.-sponsored conference in Bali.

Energy Secretary Samuel P. Bodman claimed that the Bush administration is likely to drop its support for a $1.5 billion coal-fired power plant designed to store greenhouse gases underground, citing mounting cost estimates and other possible technologies.

A large amount of the greenhouse gas nitrous oxide is produced by bacteria in the oxygen poor parts of the ocean using nitrites, Dr Mark Trimmer told journalists at a Science Media Centre press briefing.

A major study has shed new light on the dim layer of the ocean called the "twilight zone"-where mysterious processes affect the ocean's ability to absorb and store carbon dioxide accumulating in our atmosphere.
