Resilience In Shelled Plants Exposed To Ocean Acidification Found By Scientists
2013-04-15 11:35:10

University of California - Santa Barbara Marine scientists have long understood the detrimental effect of fossil fuel emissions on marine ecosystems. But a group led by a UC Santa Barbara professor has found a point of resilience in a microscopic shelled plant with a massive environmental impact, which suggests the future of ocean life may not be so bleak. As fossil fuel emissions increase, so does the amount of carbon dioxide oceans absorb and dissolve, lowering their pH levels. "As pH...

Volcanic Activity Would Have Helped Mars Sustain Liquid Water
2013-04-09 10:17:31

Brett Smith for redOrbit.com - Your Universe Online A new study suggests that Earth´s atmosphere is largely the product of carbon dioxide gas moving from the mantle to the surface through volcanic activity; if similar activity were to happen on Mars — the planet would be able to sustain liquid water. According to the study, which appeared in the early online edition of Proceedings of the National Academy of Sciences (PNAS), greenhouse gases such as methane and carbon dioxide...

ORMOND BEACH, Fla., March 28, 2013 /PRNewswire/ -- CO2Meter.com, a worldwide provider of atmospheric gas measurement equipment, has developed a new, low-cost combination carbon dioxide and methane gas level meter for use in the biogas industry. It can measure up to 100% methane (CH4) and 50% carbon dioxide (CO2) levels in real time, or can be used as a data-logger to record gas levels over time. The meter is available in 2 versions: as a hand-held, battery-operated device, or in a...

Habitat Changes Caused Turtle Collapse 71 Million Years Ago
2013-03-15 15:16:49

Lee Rannals for redOrbit.com — Your Universe Online About 71-million-years ago, turtles disappeared from Alberta's Drumheller area, and scientists have been blaming dramatic climate change as the culprit. Now, a new theory published in the journal Palaeogeography, Palaeoclimatology, Palaeoecology suggests the real reason was because of habitat changes. Researchers at the University of Calgary studying ancient soil in Red Deer River valley say it was the loss of the wetlands that...

First Evidence Of Life Deep Under Oceanic Crust Realized
2013-03-15 12:56:53

Lee Rannals for redOrbit.com — Your Universe Online Scientists writing in the journal Science say they have found the first direct evidence of life in the deeply buried oceanic crust. Researchers on board the Integrated Ocean Drilling Program's (IODP) research vessel JOIDES Resolution drilled a water depth of 1.5 miles and hundreds of feet of sediment into the oceanic crust off the west coast of North America. After examining rock samples from this depth, they were able to uncover...

After more than 10 years' work, scientists at the University of Granada have a developed a carbon gel that enables CO2 to be turned into hydrocarbons by electro-catalytic transformation. Researchers from the University of Granada (UGR) have developed a new material using doped carbon that allows low-cost energy to be produced and also reduces the amount of CO2 released into the atmosphere. The recently-patented material is a gel that enables the CO2 to be turned back into hydrocarbons via...

MOF Solar Sponge Absorbs Carbon Dioxide
2013-02-19 21:44:35

Enid Burns for redOrbit.com — Your Universe Online A group of scientists at Commonwealth Scientific and Industrial Research Organization (CSIRO), Australia's national science agency, have created a "solar sponge" using a metal organic framework (MOF) that absorbs carbon dioxide, but releases it when exposed to sunlight. The journal Angewandte Chemie published a paper detailing MOF. The interaction is known as dynamic photo-switching. The capture-and-release method of dynamic...

Emissions from coal power stations could be drastically reduced by a new, energy-efficient material that adsorbs large amounts of carbon dioxide, then releases it when exposed to sunlight. In a study published today in Angewandte Chemie, Monash University and CSIRO scientists for the first time discovered a photosensitive metal organic framework (MOF) - a class of materials known for their exceptional capacity to store gases. This has created a powerful and cost-effective new tool to...

Study Measures Vulnerability Of Earth’s Lungs
2013-02-07 09:46:02

April Flowers for redOrbit.com - Your Universe Online Because they draw in carbon dioxide and breathe out oxygen, tropical rainforests are often called "the lungs of the planet." However, yearly variations in climate can cause the amount of carbon dioxide absorbed and released by these forests to vary considerably. A new study conducted by a team of scientists from the University of Exeter, the Met Office-Hadley Centre and the Natural Environmental Research Council´s (NERC) Centre...

Can The Sea Urchin Help Scientists Curb Global Warming?
2013-02-05 11:22:20

Brett Smith for redOrbit.com - Your Universe Online A discovery that was stumbled upon by happenstance could help solve the problem of global warming. According to a new report in the academic journal Catalysis Science & Technology, two researchers at Newcastle University in the U.K. found a nickel catalyst can be used to rapidly and cheaply capture carbon emissions. "We had set out to understand in detail the carbonic acid reaction — which is what happens when CO2...

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...
