Dryland Ecosystems Emerge As Driver In Global Carbon Cycle
2014-05-22 03:17:36

Montana State University Dryland ecosystems, which include deserts to dry-shrublands, play a more important role in the global carbon cycle than previously thought. In fact, they have emerged as one of its drivers, says Montana State University faculty member Ben Poulter. Surprised by the discovery, Poulter and his collaborators explained their findings in Nature. At the same time, they urged global ecologists to include the emerging role of dryland ecosystems in their research. Nature...

Borneo’s Super-charged Tropical Trees Are Vitally Important For Global Carbon Cycling
2014-05-12 03:31:15

Centre for Ecology & Hydrology A team of scientists has found that the woody growth of forests in north Borneo is half as great again as in the most productive forests of north-west Amazonia, an average difference of 3.2 tons of wood per hectare per year. The new study, published today in the Journal of Ecology, examined differences in above-ground wood production (one component of the total uptake of carbon by plants) which is critically important in the global cycling of carbon....

How Does Your Garden Glow?

By Laurie J. Schmidt, NASA's Jet Propulsion Laboratory Science is full of serendipity -- moments when discoveries happen by chance or accident while researchers are looking for something else. For example, penicillin was identified when a blue-green mold grew on a Petri dish that had been left open by mistake. Now, satellite instruments have given climate researchers at NASA and other research institutions an unexpected global view from space of a nearly invisible fluorescent glow that...

NASA's Orbiting Carbon Observatory-2 Satellite Arrives At Launch Site
2014-05-02 03:28:08

NASA's Jet Propulsion Laboratory A NASA spacecraft designed to make precise measurements of carbon dioxide in Earth's atmosphere is at Vandenberg Air Force Base, Calif., to begin final preparations for launch. The Orbiting Carbon Observatory-2 arrived Wednesday at its launch site on California's central coast after traveling from Orbital Sciences Corp.'s Satellite Manufacturing Facility in Gilbert, Ariz. The spacecraft now will undergo final tests and then be integrated on top of a...

Biologists Help Solve Fungi Mysteries
2014-04-18 08:24:38

By Bjorn Carey, Stanford University A new genetic analysis revealing the previously unknown biodiversity and distribution of thousands of fungi in North America might also reveal a previously underappreciated contributor to climate change. Pine forests are chock full of wild animals and plant life, but there's an invisible machine underground. Huge populations of fungi are churning away in the soil, decomposing organic matter and releasing carbon into the atmosphere. Despite the...

By Carol Rasmussen, NASA Earth Science News Team Simply by breathing, humans have played a small part in the planet-wide balancing act called the carbon cycle throughout our existence. However, in the last few hundred years, we have taken a larger role. Our activities, such as fossil fuel burning and deforestation, are pushing the cycle out of its natural balance, adding more and more carbon dioxide to the atmosphere. Natural processes are working hard to keep the carbon cycle in...

April Flowers for redOrbit.com - Your Universe Online During the Northern Hemisphere's growing season, data returned from satellite sensors shows that the Midwest has more photosynthetic activity than any other region of the planet, according to a recent NASA report. School children are taught that plants convert light to energy through the process of photosynthesis. What is less known, however, is that chlorophyll also emits a fraction of the absorbed light as fluorescent glow, which...

Reimagining How Earth Emerged Out Of Ice Age
2014-03-19 14:15:38

Lee Rannals for redOrbit.com - Your Universe Online Researchers, publishing a paper in the journal Nature, say rapid erosion in mountain regions could explain why the Earth isn’t essentially still a snowball. Scientists have long believed that rocks pushed up to the surface by plate tectonics absorbed atmospheric carbon dioxide, and volcanic processes are what helps to emit this CO2. However, despite this theory and a variety of other hypotheses being put forward to balance the...

Amazon Inhales More Carbon Than It Emits
2014-03-18 20:28:30

NASA's Jet Propulsion Laboratory A new NASA-led study seven years in the making has confirmed that natural forests in the Amazon remove more carbon dioxide from the atmosphere than they emit, therefore reducing global warming. This finding resolves a long-standing debate about a key component of the overall carbon balance of the Amazon basin. The Amazon's carbon balance is a matter of life and death: living trees take carbon dioxide out of the air as they grow, and dead trees put the...
