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.

An experimental gas turbine simulator equipped with an ultralow-emissions combustion technology called LSI has been tested successfully using pure hydrogen as a fuel – a milestone that indicates a potential to help eliminate millions of tons of carbon dioxide and thousands of tons of NOx from power plants each year.

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.

World Wildlife Fund announced its opposition to a plan by Planktos, Inc. (OTCBB: PLKT) to dump iron dust in the open ocean west of the Galapagos Islands. The experiment seeks to induce phytoplankton blooms in the hopes that the microscopic marine plants will absorb carbon dioxide. The company is speculating on lucrative ways to combat climate change.

According to a new study, China's carbon dioxide emissions last year were the largest in the world.

Forests in the United States and other northern mid- and upper-latitude regions are playing a smaller role in offsetting global warming than previously thought, according to a study appearing in Science this week.

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.

The first buoy to monitor ocean acidification has been launched in the Gulf of Alaska. Attached to the 10-foot-diameter buoy are sensors to measure climate indicators.

While solar power and hybrid cars have become popular symbols of green technology, Stanford researchers are exploring another path for cutting emissions of carbon dioxide, the leading greenhouse gas that causes global warming.

Using a soil model may provide farmers and landowners who are looking to trade carbon credits with a way to measure the amount of carbon being stored

Scientists have observed the first evidence that the Southern Ocean's ability to absorb the major greenhouse gas, carbon dioxide, has weakened by about 15 per cent per decade since 1981.
