Eye-Popping View of CO2, Critical Step for Carbon-Cycle Science

NASA’s new global view of carbon dioxide builds on the agency’s previous satellite measurements of carbon dioxide and combines them with a sophisticated Earth system model to provide one of the most realistic views yet of how this critical greenhouse gas moves through the atmosphere. Scientists have tracked the rising concentration of heat-trapping carbon dioxide […]

Carbon Release from Ocean Helped End the Ice Age

New research shows that high concentrations of dissolved carbon dioxide in ocean water coincides with rises in atmospheric carbon dioxide and global temperatures at the end of the last ice age, giving scientists valuable insights into how the ocean can affect the carbon cycle and climate change. New techniques are allowing scientists to understand how […]

Study Finds Natural Impediment to Long-Term Sequestration of Carbon Dioxide

A new study reveals a natural impediment to the long-term sequestration of carbon dioxide, showing that as carbon dioxide works its way underground only a small fraction of the gas turns to rock. The remainder of the gas stays in a more tenuous form. Carbon sequestration promises to address greenhouse-gas emissions by capturing carbon dioxide […]

Study Shows Tropical Forests Absorbing More Carbon Dioxide

A newly published study from NASA scientists shows that tropical forests, like the one pictured above, absorb more atmospheric carbon dioxide than boreal forests. A new NASA-led study shows that tropical forests may be absorbing far more carbon dioxide than many scientists thought, in response to rising atmospheric levels of the greenhouse gas. The study […]

A Year in the Life of Earth's CO2

This three minute video shows how carbon dioxide in the atmosphere travels around the globe over a 12 month period. An ultra-high-resolution NASA computer model has given scientists a stunning new look at how carbon dioxide in the atmosphere travels around the globe. Plumes of carbon dioxide in the simulation swirl and shift as winds […]

NASA Preparing to Launch Carbon Observatory

NASA is about to launch the Orbiting Carbon Observatory – a satellite dedicated to the study of global carbon dioxide sources that will help researchers predict the future of climate change. In the lexicon of climate change, one word appears more often than any other: “carbon.” Carbon credits, carbon emissions, carbon sequestration…. These terms are […]

EU's-Carbon-Capture-and-Storage-Problem

Europe’s carbon-trading market and tougher emission targets make it appear somewhat more responsible than the rest of the world at climate-policy negotiations. But recently, the region has fallen behind North America in the effort demonstrate systems for capturing greenhouse-gas emissions from power plants and industry, even as its coal use increases. Europe has had trouble […]

methane consuming microorganisms

Scientists at MARUM and the Max Planck Institute for Marine Microbiology explore the unique diets of methane consuming microorganisms. Methane is formed under the absence of oxygen by natural biological and physical processes, e.g. in the sea floor. It is a much more powerful greenhouse gas than carbon dioxide. Thanks to the activity of microorganisms […]

Carbon Dioxide Impairs Decision-Making Performance

A recently published study from scientists at the Berkeley Lab, in collaboration with researchers at SUNY Upstate Medical University, found that moderately high indoor concentrations of CO2 can significantly impair people’s decision-making performance. Overturning decades of conventional wisdom, researchers at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have found that moderately high […]

forest-ecosystems

As carbon dioxide levels continue to climb in the Earth’s atmosphere, most current climate models project that the world’s oceans and trees will keep soaking up more than half of the extra CO2. However, researchers have spotted a problem with the capacity of plants to absorb more CO2. It’s now expected that this capacity will […]

first ‘bottom-up’ estimates of China's CO2 emissions

A newly published study gives the first “bottom-up” estimates of China’s carbon dioxide (CO2) emissions for 2005 – 2009, combining the results of Chinese field studies of CO2 emissions from diverse combustion processes with a plant-by-plant data set for power generation, independent research on transportation and rural biomass use, and provincial-level energy statistics for the […]

Researchers have determined the size of CO2 snow particles on Mars

By using data gathered from instruments onboard the Mars Global Surveyor and Mars Reconnaissance Orbiter, scientists at MIT have calculated the size of snow particles in clouds at both Martian poles, finding that snow particles at both poles are about the size of a red blood cell with particles in the south being slightly smaller […]

Algae, mosses, and lichens take up approximately 14 billion tons of carbon dioxide

New research from the Max Planck Institute examines the role of cryptogamic covers in the global exchange of oxygen, carbon, and nitrogen. Covering approximately 30% of soil surface that includes the surfaces of plants, the scientists found that algae, mosses, and lichens take up approximately 14 billion tons of carbon dioxide and fix approximately 50 […]

Octagonal Window for Carbon Capture

Researchers from the National Institute of Standards and Technology and the University of Delaware are working together to reduce greenhouse gas emissions. They believe a material called a zeolite, which has octagonal “windows” between its interior pore spaces, might help reduce carbon dioxide coming from factory smokestacks far more efficiently than current models. Filtering carbon […]

USC scientists develop material that can scrub large amounts of carbon dioxide from the air

By using fumed silica impregnated with polyethlenimine, researchers at the USC Loker Hydrocarbon Research Institute aim to recycle harmful excess carbon dioxide in the atmosphere. Their new material can absorb carbon dioxide from both dry and humid air and can release it simply by heating it up. With ongoing research, the scientists hope this technology […]
