The outer edge of a star's habitable zone a hard place for life
Jul 12, 2016
Earth is situated right in the middle of our Sun's habitable zone and it's a comfortable place for life. We enjoy a relatively stable climate and the right amount of warmth to allow liquid water.
NASA's field campaign investigates Arctic North American ecosystems
Jul 08, 2016
Sampling charred soils in Saskatchewan, outfitting robins with GPS backpacks in Alberta, and measuring the growth rates of trees in northern Alaska - scientists with a decade-long NASA project are in the field this summer ...
Microbes, nitrogen and plant responses to rising atmospheric carbon dioxide
Jun 30, 2016
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 ...
