Microbes, nitrogen and plant responses to rising atmospheric carbon dioxide
21 hours ago
Plants can grow faster as atmospheric carbon dioxide concentrations increase, but only if they have enough nitrogen or partner with fungi that help them get it, according to new research published this week in Science.
Warning from the past: Future global warming could be even warmer
Jun 23, 2016
Future global warming will not only depend on the amount of emissions from man-made greenhouse gasses, but will also depend on the sensitivity of the climate system and response to feedback mechanisms. By reconstructing past ...
Pollution resulting from burning fossil fuels reaches the open ocean via the atmosphere
May 16, 2016
Polycyclic aromatic hydrocarbons are pollutants which come from burning fossil fuels, fires, oil spillages, and other anthropogenic and natural sources. They are transported from continental land masses to the open ocean ...
Small headwater streams export surprising amounts of carbon out of Pacific Northwest forest
May 13, 2016
Scientists have tracked a higher-than-expected amount of carbon flowing out of a Pacific Northwest forest from month to month through a small headwater stream, suggesting that forested watersheds may not store quite as much ...
Space mission to 'weigh' Earth's forests moves closer to launch
May 10, 2016
A pioneering mission to measure the Earth's forests from space, conceived by an international team of researchers led by the University of Sheffield, has moved a step closer to launch following the signing of a contract to ...
UCI sleuths search the seas for soot
May 09, 2016
Earth system scientists from the University of California, Irvine have taken water samples from the north Pacific, north and south Atlantic, and Arctic oceans in search of repositories of black carbon, soot from burning biomass ...
Proteomics method measures carbon uptake of marine microbes
Apr 26, 2016
In a paper published April 26th in mSystems, a team of researchers led by microbiologists at Oregon State University, in Corvallis, describe a successful trial of a new method of identifying the carbon uptake of specific ...
Dinosaur die-off not a result of volcanoes, new study says
Apr 26, 2016
A new study suggests that volcanic eruptions did not lead to the extinction of the dinosaurs, and also demonstrates that Earth's oceans are capable of absorbing large amounts of carbon dioxide—provided it is released gradually ...
Researchers develop scientific plan to measure ocean's carbon cycle and predict its future conditions
Mar 30, 2016
Vast and amorphous, the ocean covers more than 70 percent of the Earth's surface. It is a key player in the global carbon cycle, producing about half of the world's output of organic carbon.
Molecular-level relationships key to deciphering ocean carbon
Mar 07, 2016
From beach shallows to the ocean depths, vast numbers of chemical compounds work together to reduce and store atmospheric carbon in the world's oceans.
