climate change models
2014-10-15 06:30:22

Brett Smith for redOrbit.com - Your Universe Online New research led by scientists at the Oak Ridge National Laboratory in Tennessee has found that global climate change models may have underestimated the amount of carbon dioxide absorption by green plants. Published in the Proceedings of the National Academy of Sciences, the new study’s conclusion was based on the slow diffusion of CO2 in plant leaves, particularly the mechanisms taking place within inner leaf tissues. "Carbon...

CO2 Monitor meets Navy data logging and battery life criteria to give accurate data CO2 exposure of military personnel. ORMOND BEACH, Fla., Oct. 1, 2014 /PRNewswire/ -- The United States Navy has contracted with CO2Meter, Inc. to provide carbon dioxide monitoring devices to measure ambient CO2 levels in expeditionary shelters. The CO2 monitors were designed under the direction of the U.S. Navy for meeting their required data logging and battery life criteria. The monitor will...

On the Road To Artificial Photosynthesis
2014-09-28 06:00:11

Lynn Harris, Berkeley Lab The excessive atmospheric carbon dioxide that is driving global climate change could be harnessed into a renewable energy technology that would be a win for both the environment and the economy. That is the lure of artificial photosynthesis in which the electrochemical reduction of carbon dioxide is used to produce clean, green and sustainable fuels. However, finding a catalyst for reducing carbon dioxide that is highly selective and efficient has proven to be a...

Initiative to Reduce Food Spoilage, Increase Efficiency, and Reduce HFC Emissions NEW YORK, Sept. 23, 2014 /PRNewswire-USNewswire/ -- A coalition of major companies that comprise the supply chain necessary to move cold food products from field to market around the world today announce the organization of the Global Food Cold Chain Council. This initiative seeks to reduce greenhouse gas emission in the processing, transportation, storage and retail display of cold food and to...

Sea Ice Helps Remove CO2 From The Atmosphere
2014-09-23 03:30:21

University of Southern Denmark Climate change is a fact, and most of the warming is caused by human activity. The Arctic is now so warm that the extent of sea ice has decreased by about 30 pct. in summer and in winter, sea ice is getting thinner. New research has shown that sea ice removes CO2 from the atmosphere. If Arctic sea ice is reduced, we may therefore be facing an increase of atmospheric concentration of CO2, researchers warn. Due to global warming, larger and larger areas of...

University of Miami Rosenstiel School of Marine and Atmospheric Science Scientists analyze marine sediment core to understand trends in carbon isotopes over time A recent study of the global carbon cycle offers a new perspective of Earth’s climate records through time. Scientists at the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science suggest that one of the current methods for interpreting ancient changes in the concentration of carbon dioxide in the...

Research By NASA Provides Guideline For Future Alien Life Search
2014-09-15 03:57:50

NASA Astronomers searching the atmospheres of alien worlds for gases that might be produced by life can't rely on the detection of just one type, such as oxygen, ozone, or methane, because in some cases these gases can be produced non-biologically, according to extensive simulations by researchers in the NASA Astrobiology Institute’s Virtual Planetary Laboratory. The researchers carefully simulated the atmospheric chemistry of alien worlds devoid of life thousands of times over a...

Sharks In Acidic Waters Could Lose Ability To Smell Food
2014-09-12 03:05:34

By Brett Israel, Georgia Institute of Technology The increasing acidification of ocean waters caused by rising atmospheric carbon dioxide levels could rob sharks of their ability to sense the smell of food, a new study suggests. Elevated carbon dioxide levels impaired the odor-tracking behavior of the smooth dogfish, a shark whose range includes the Atlantic Ocean off the eastern United States. Adult sharks significantly avoided squid odor after swimming in a pool of water treated...

greenhouse gas bulletin
2014-09-09 07:28:44

Chuck Bednar for redOrbit.com - Your Universe Online Propelled by the largest single-year increase in carbon dioxide in three decades, the amount of greenhouse gases in the atmosphere reached record highs in 2013, the World Meteorological Organization (WMO) reported on Tuesday. According to the agency’s annual Greenhouse Gas Bulletin, there was a 34 percent increase in radiative forcing (the warming effect on our climate) due to CO2, methane and nitrous oxide. The report found that...

earth atmosphere ozone layer mystery
2014-09-08 05:20:11

Dr. Tony Phillips, Science@NASA High above Earth, more than 20 miles above sea level, a diaphanous layer of ozone surrounds our planet, absorbing energetic UV rays from the sun. It is, essentially, sunscreen for planet Earth. Without the ozone layer, we would be bathed in dangerous radiation on a daily basis, with side effects ranging from cataracts to cancer. People were understandably alarmed, then, in the 1980s when scientists noticed that manmade chemicals in the atmosphere were...

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...
