In a commentary in the September 25, 2007, issue of the Geophysical Research Letters (GRL), a large team of scientists state that human-induced carbon dioxide emissions will alter ocean chemistry to the point where it will violate U.S.

Determining the concentration of carbon dioxide in the ancient atmosphere remains a critical hurdle to understanding Earth surface temperatures, compositional changes in atmospheric chemistry, and the evolution of Earth’s earliest biosphere.

Fujitsu America, Inc. dedicated a hydrogen fuel cell on its Sunnyvale campus. The fuel cell provides clean, efficient power for the campus data center and other operations, significantly reducing carbon dioxide emissions.

While 10 years of bathing North Carolina pine tree stands with extra carbon dioxide did allow the trees to grow more tissue, only those pines receiving the most water and nutrients were able to store significant amounts of carbon that could offset the effects of global warming, scientists told a national meeting of the Ecological Society of America (ESA).

In future drivers may only have to glance at the dashboard to see the pollution spewing out of their vehicle’s exhausts.

Cutting-edge technology that 'captures' polluting carbon dioxide and stores it permanently inside rocks will be developed at a new £1.1m research centre at The University of Nottingham.

Global warming will cause more deaths in summer because of higher temperatures but these will not be offset by fewer deaths in milder winters finds an analysis published online ahead of print in Occupational and Environment Medicine.

The Chinese government says criticism of the country's carbon dioxide emissions are "unfair," and says western companies manufacturing in China should share the blame.

Human-caused nitrogen deposition has been indirectly "fertilizing" forests, increasing their growth and sequestering major amounts of carbon, a new study in the journal Nature suggests.

Carnegie Mellon University engineering researchers Christopher L. Weber and Scott H. Matthews argue that rising U.S. trade with countries like China has major consequences for the future of global climate policy.

German Chancellor Angela Merkel has hailed agreement by G8 leaders to work for greenhouse-emissions cuts, though the deal sets no specific benchmarks and thus falls short of her ambitious hopes.

Radical steps to engineer Earth's climate by blocking sunlight could drastically cool the planet, but could just as easily worsen the situation if these projects fail or are suddenly halted, according to a new computer modeling study.
