Soil pores, carbon stores, and breathing microbes
23 hours ago
Researchers at the Pacific Northwest National Laboratory (PNNL) recently studied how moisture influences soil heterotrophic respiration. That's the breathing-like process by which microbes convert dead organic carbon in the ...
Researchers derive valuable chiral amino-alcohol structures from CO2
Jan 16, 2017
Researchers at the Institute of Chemical Research of Catalonia (ICIQ) in Tarragona have developed a method that transforms cyclic carbonates that can be easily obtained from CO2 into more valuable, chiral molecules chemists ...
Deep mantle chemistry surprise: Carbon content not uniform
Jan 13, 2017
Even though carbon is one of the most-abundant elements on Earth, it is actually very difficult to determine how much of it exists below the surface in Earth's interior. Analysis by Carnegie's Marion Le Voyer and Erik Hauri ...
Amino acids formed from the single-electron activation of carbon dioxide
Jan 12, 2017 report
(Phys.org)—Carbon dioxide, an abundant greenhouse gas, is very difficult to use as a carbon source for carbon-carbon bond formation. CO2 is highly stable and unreactive, requiring prohibitively difficult or toxic reagents ...
Report recommends new framework for estimating the social cost of carbon
Jan 11, 2017
To estimate the social cost of carbon dioxide for use in regulatory impact analyses, the federal government should use a new framework that would strengthen the scientific basis, provide greater transparency, and improve ...
Effect of methane on climate change could be 25% greater than we thought
Jan 10, 2017
Methane emissions caused by human activity may have a bigger impact on global warming than previously thought, scientists have found.
Ancient human disturbances may skew understanding of Amazon and its impact (Update)
Jan 10, 2017
Pre-European human populations of the Amazon Basin may have affected our contemporary understanding of the forest's structure and composition, and thus our calculations of its impact on carbon dioxide remediation, according ...
Short-lived greenhouse gases cause centuries of sea-level rise
Jan 09, 2017
Even if there comes a day when the world completely stops emitting greenhouse gases into the atmosphere, coastal regions and island nations will continue to experience rising sea levels for centuries afterward, according ...
Crystallization method offers new option for carbon capture from ambient air
Jan 09, 2017
Scientists at the Department of Energy's Oak Ridge National Laboratory have found a simple, reliable process to capture carbon dioxide directly from ambient air, offering a new option for carbon capture and storage strategies ...
High-tech mooring will measure beneath Antarctic ice
Jan 05, 2017
Earth's oceans have soaked up about a third of the carbon dioxide added to the atmosphere by humans through use of fossil fuels and other activities. That's good news for those concerned with greenhouse warming, but bad news ...
