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?

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...

Beef Cows Produce More Methane During Calving Stage
2013-01-31 06:09:53

April Flowers for redOrbit.com - Your Universe Online It is a well-known fact that cattle produce carbon dioxide and methane throughout their lives. A new study, however, pinpoints the cow-calf stage as a major contributor of greenhouse gases during beef production. The research team estimated greenhouse gas emissions from beef cattle during different stages of life in the new study, recently published in the Journal of Animal Science. Their findings reveal that, depending on which...

Jurassic Ecosystem
2013-01-09 06:26:57

Rayshell Clapper for redOrbit.com - Your Universe Online According to Southern Methodist University paleontologists Timothy S. Myers, Louis L. Jacobs, and SMU sedimentary geologist Neil J. Tabor, the modern relationship between animals and vegetation is similar to millions of years ago. In their study, the SMU scientists used fossil soils from the Late Jurassic age gathered from locations where animal fossils were previously found to determine the levels of carbon isotopes. The team...

As digital cameras become better and cheaper, ecologists are turning these ubiquitous consumer devices into scientific tools to study how forests are responding to climate change. And, they say, digital cameras could be a cost-effective way of visually monitoring the spread of tree diseases. The results — which come from 38,000 photographs — are presented at this week's British Ecological Society's Annual Meeting at the University of Birmingham. Because trees fix carbon dioxide...

A new study by the Center for the Study of Carbon Dioxide and Global Change — "The State of Earth´s Terrestrial Biosphere: How is it Responding to Rising Atmospheric CO2 and Warmer Temperatures?" — refutes claims by the United Nations´ Intergovernmental Panel on Climate Change (IPCC) that global warming is stressing Earth´s natural and agro-ecosystems by reducing plant growth and development. CHICAGO, IL (PRWEB) December 12, 2012 A new study by the Center for the...

Carbon Dioxide Reduces Crop Yields
2012-12-01 10:45:02

April Flowers for redOrbit.com — Your Universe Online Atmospheric carbon dioxide content continues its climb, heating up the climate. For plants, however, the gas is a necessary part of their survival. It provides the carbon needed to produce glucose and other important substances, leading scientists to question if more carbon dioxide is better. The answer isn't as simple as that, unfortunately. The plants used for our most basic food supply today have not been bred for vertical...

GI Researcher Co-author Of Report On International Permafrost
2012-11-28 09:25:17

University of Alaska Fairbanks University of Alaska Fairbanks researcher Vladimir Romanovsky is one of four scientists who authored a report released today by the United Nations Environmental Programme. The report, "Policy Implications of Warming Permafrost," seeks to highlight the potential hazards of carbon dioxide and methane emissions from warming permafrost, which have not thus far been included in climate-prediction modeling. The report notes that permafrost covers almost a...

Ocean Acidification Threatens Antarctic Marine Wildlife
2012-11-26 05:01:08

redOrbit Staff & Wire Reports - Your Universe Online An international team of researchers has uncovered the first evidence that marine creatures living in the Antarctic region are being affected by ocean acidification. That evidence was discovered in 2008, when researchers from the British Antarctic Survey (BAS), the University of East Anglia (UEA), the Woods Hole Oceanographic Institution (WHOI) and the National Oceanic and Atmospheric Administration (NOAA) observed that the shells...

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...
