The Earth's forests serve as crucial carbon sinks due to their ability to absorb greenhouse gases, but that ability is "at risk of being lost entirely", according to a new United Nations report. Currently, the Earth's forests soak up about 25 percent of greenhouse gas emissions, but that capability could be reversed if the Earth heats up 2.5 degrees Celsius (4.5 degrees F) more. A rise in temperature could cause severe droughts and heat waves that would kill off many of the Earth's forests...

Researchers said on Wednesday that water deep below ground has safely trapped carbon dioxide for millions of years and may one day help absorb emissions of the greenhouse gas to help slow climate change, Reuters reported. Chris Ballentine, a researcher at the University of Manchester, who worked on the study, said the finding shows that such carbon capture and storage is possible provided scientists find an area where the geology is suitable. Therefore, researchers can locate ancient deep...

Officials with the U.S. Department of Agriculture (USDA) said Wednesday that its Conservation Reserve Program (CRP), which compensates landowners to idle their farmland, could become one of the nation's biggest carbon sequestration program on private land. Some members of Congress  who represent farm states say work to reduce greenhouse gases could ultimately pay off for rural America, since some agricultural activities, such as reduced tillage, can lock carbon into the soil. "Land...

The Amazon is surprisingly sensitive to drought, according to new research conducted throughout the world's largest tropical forest. The 30-year study, published today in Science, provides the first solid evidence that drought causes massive carbon loss in tropical forests, mainly through killing trees. "For years the Amazon forest has been helping to slow down climate change. But relying on this subsidy from nature is extremely dangerous", said Professor Oliver Phillips, from the University...

A top Australian scientist said Thursday that the nation's bushfires, which have devastated Victoria state, have released millions of tons of carbon dioxide into the atmosphere.  The Victoria fires, many of which are still burning, have killed more than 200 people and were the worst in Australia's history. Mark Adams of the University of Sydney said forest fires could become a growing source of carbon pollution as the Earth continues to warm, triggering a vicious cycle in which forests...

Researchers have great expectations for the soon-to-launch NASA satellite that will provide an unprecedented map of carbon dioxide emissions on Earth. Slated to launch on Tuesday from Vandenberg Air Force Base in California, the Orbiting Carbon Observatory will give scientists a more accurate depiction of concentrations of carbon dioxide in Earth's atmosphere. Ground-based carbon dioxide monitoring efforts can only provide so much information, and NASA believes its orbiting observatory will...

As the concentration of heat-trapping carbon dioxide in Earth's atmosphere continues to rise, so also does public awareness, as well as efforts to find solutions to this global problem. Increasing concentrations of this potent greenhouse gas threaten to alter Earth's climate in ways that will have profound impacts on the welfare and productivity of society and Earth's ecosystems. This year marks the 50th anniversary of Scripps Institution of Oceanography scientist Charles David...

Trees absorb nearly one-fifth of humanity's climate-change emissions, a 40-year British university study finds. The University of Leeds study is being hailed by environmentalists as the most compelling evidence yet supporting an end to the logging or burning of trees in forested areas. Previous studies on the value of the rainforests had concentrated on South America and Asia. But the Leeds research included tropical forests in Africa and found trees absorb 4.8 billion tons of carbon dioxide...

Researchers found that tropical forests are absorbing nearly a fifth of the CO2 released by burning fossil fuels, taking 4.8 billion tons of CO2 emissions from the atmosphere each year. The British scientists found tropical trees have grown bigger over the past 40 years and are able absorb more fossil fuel emissions from the atmosphere, highlighting the need to preserve threatened forests. The team used data collected from nearly 250,000 trees in the world's tropical forests over the past 40...

In the Southern Indian Ocean, climate change is leading to stronger winds, which mix waters, bringing CO2 up from the ocean depths to the surface. This is the conclusion of researchers who have studied the latest field measurements carried out by CNRS's INSU, IPEV and IPSL. As a result, the Southern Ocean can no longer absorb as much atmospheric CO2 as before. Its role as a 'carbon sink' has been weakened, and it may now be ten times less efficient than previously estimated. The same trend...
