How Mountains And Rivers Make Life Possible
2014-03-14 14:47:09

Stanford University Favorable conditions for life on Earth are enabled in part by the natural shuttling of carbon dioxide from the planet's atmosphere to its rocky interior and back again. Now Stanford scientists have devised a pair of math equations that better describe how topography, rock compositions and the movement of water through a landscape affects this vital recycling process. Scientists have long suspected that the so-called the geologic carbon cycle is responsible for...

Ocean Food Web Plays Key Role In The Global Carbon Cycle
2014-03-12 10:39:50

University of California - Santa Barbara Nothing dies of old age in the ocean. Everything gets eaten and all that remains of anything is waste. But that waste is pure gold to oceanographer David Siegel, director of the Earth Research Institute at UC Santa Barbara. In a study of the ocean's role in the global carbon cycle, Siegel and his colleagues used those nuggets to their advantage. They incorporated the lifecycle of phytoplankton and zooplankton — small, often microscopic animals...

The tropical carbon cycle has become twice as sensitive to temperature variations over the past 50 years, new research has revealed. The research shows that a one degree rise in tropical temperature leads to around two billion extra tonnes of carbon being released per year into the atmosphere from tropical ecosystems, compared with the same tropical warming in the 1960s and 1970s. Professor Pierre Friedlingstein and Professor Peter Cox, from the University of Exeter, collaborated with...

Earth’s CO2 And Climate Stabilized By Ancient Forests
2014-01-24 12:38:58

European Geosciences Union UK researchers have identified a biological mechanism that could explain how the Earth’s atmospheric carbon dioxide and climate were stabilized over the past 24 million years. When CO2 levels became too low for plants to grow properly, forests appear to have kept the climate in check by slowing down the removal of carbon dioxide from the atmosphere. The results are now published in Biogeosciences, an open access journal of the European Geosciences Union (EGU)....

Mushrooms Associated To Earthworms Can Develop Mechanism Of Environmental Engineering
2014-01-13 12:25:49

Technical University of Madrid This model, which was developed by a research group of the School of Forestry at the Technical University of Madrid (UPM), has shown how some types of mushrooms (such as truffles, boletus or chanterelles) associated to earthworms can develop a mechanism of environmental engineering. The use of this model can increase the levels of calcium and salts among tree roots what can result in an increase in mycorrhizas and to enhance the development of forests. This...

Scientists discover extracellular vesicles produced by ocean microbes Marine cyanobacteria — tiny ocean plants that produce oxygen and make organic carbon using sunlight and CO2 — are primary engines of Earth's biogeochemical and nutrient cycles. They nourish other organisms through the provision of oxygen and with their own body mass, which forms the base of the ocean food chain. Now scientists at MIT have discovered another dimension of the outsized role played by these tiny...

Fungi Fight Climate Change
2014-01-09 12:01:24

Ranjini Raghunath for redOrbit.com - Your Universe Online Most people know fungi as the yeast that makes their bread or the mold that leaves them wheezing at night. But there are hundreds of these creatures working quietly on the sidelines to make the world a better place: from brewing beer to keeping the soil fertile and now, it turns out, combating climate change. A new study published online in Nature reveals that fungi, not plants, are the real champions in the battle against...

How Does Soil Store Carbon Dioxide?
2014-01-09 10:17:12

Technische Universität München Global carbon dioxide (CO2) emissions continue to rise – in 2012 alone, 35.7 billion tons of this greenhouse gas entered the atmosphere. Some of this CO2 is absorbed by the oceans, plants and soil. As such, they provide a significant reservoir of carbon, stemming the release of CO2. Scientists have now discovered how organic carbon is stored in soil. Basically, the carbon only binds to certain soil structures. This means that soil’s capacity to absorb...

Carbon Dioxide Observatory Spacecraft Placed In Vacuum Chamber In Preps For Launch
2013-12-26 03:31:31

Gerard LeBlond for redOrbit.com - Your Universe Online NASA’s Orbiting Carbon Observatory (OCO-2) was recently placed into a thermal vacuum chamber to prepare for its launch in July 2014. The OCO-2 is a craft that will orbit the Earth and take high-resolution data of carbon dioxide levels in the atmosphere. It was prepped and tested at the Orbital Sciences Satellite Manufacturing Facility in Gilbert, Arizona. In late November the OCO-2 was placed into the vacuum chamber to confirm the...

Rivers, Streams Release Far More Carbon Dioxide Than Do Lakes: Study
2013-12-10 06:51:50

April Flowers for redOrbit.com - Your Universe Online Contrary to common belief, rivers and streams release carbon dioxide (CO2) into the atmosphere at a rate five times greater than the world's lakes and reservoirs combined. The findings of this international study, which included the University of Waterloo, have been published in the journal Nature. "Identifying the sources and amounts of carbon dioxide released from continental water sources has been a gap in understanding the carbon...
