3 billion-year-old Rocks Contain Microfossils Of Plankton
2013-06-06 21:18:25

Penn State Spindle-shaped inclusions in 3 billion-year-old rocks are microfossils of plankton that probably inhabited the oceans around the globe during that time, according to an international team of researchers. "It is surprising to have large, potentially complex fossils that far back," said Christopher H. House, professor of geosciences, Penn State, and lead author. However, the researchers not only showed that these inclusions in the rocks were biological in origin, but also...

Elevated Carbon Dioxide Is making Arid Regions Greener
2013-05-31 11:25:37

American Geophysical Union Scientists have long suspected that a flourishing of green foliage around the globe, observed since the early 1980s in satellite data, springs at least in part from the increasing concentration of carbon dioxide in Earth´s atmosphere. Now, a study of arid regions around the globe finds that a carbon dioxide “fertilization effect” has, indeed, caused a gradual greening from 1982 to 2010. Focusing on the southwestern corner of North America,...

New CO2 Removal Technique Produces Green Fuel, Offsets Ocean Acidification
2013-05-29 10:31:52

April Flowers for redOrbit.com - Your Universe Online A new technique to remove and store atmospheric carbon dioxide has been demonstrated by scientists at the Lawrence Livermore National Laboratory (LLNL). The new technique also generates carbon-negative hydrogen and produces alkalinity, which can be used to offset ocean acidification. At laboratory scale, the team demonstrated a system that uses the acidity normally produced in saline water electrolysis to accelerate silicate mineral...

Experts To Track Big City Carbon Footprints
2013-05-13 04:38:01

redOrbit Staff & Wire Reports - Your Universe Online Scientists from across the globe are joining forces to track the carbon footprints of some of the world´s largest cities, hoping to determine whether or not emissions standards in various regions are being met. According to Associated Press (AP) reporter Alicia Chang, the efforts are being focused on cities like Paris and Los Angeles, which are home to more than 10 million residents. In recent years, she said, these...

Revised Estimates Show CO2 Levels Had Not Actually Surpassed 400ppm
2013-05-13 13:30:18

redOrbit Staff & Wire Reports — Your Universe Online Update (May 13 @ 1:30 p.m.) Revised statistics released by the National Oceanic and Atmospheric Administration (NOAA) on Monday have revealed that average carbon dioxide levels at the Mauna Loa Observatory had not surpassed the 400 parts per million (ppm) level as originally reported. Instead, the average weekly CO2 levels at the Hawaiian facility for May 9 was 399.89 ppm. The agency had initially reported on Friday that...

Studying Mystery Of 'Eternal Flames'
2013-05-09 10:52:58

Indiana University "Eternal flames" fueled by hydrocarbon gas could shine a light on the presence of natural gas in underground rock layers and conditions that let it seep to the surface, according to research by geologists at the Department of Geological Sciences and the Indiana Geological Survey at Indiana University Bloomington. A little-known but spectacular flame in Erie County, N.Y., is the focus of an article in the journal Marine and Petroleum Geology, co-authored by Agnieszka...

Earth's Atmosphere
2004-10-19 04:45:44

Earth's Atmosphere -- Earth's atmosphere consists of nitrogen (78.1%) and oxygen (20.9%), with small amounts of argon (0.9%), carbon dioxide (variable, but around 0.035%), water vapor, and other gases. The atmosphere protects life on Earth by absorbing ultraviolet solar radiation and reducing temperature extremes between day and night. 75% of the atmosphere exists within 11km of the planetary surface. Temperature and the Atmospheric Layers The temperature of the Earth's atmosphere...
