On the Road To Artificial Photosynthesis

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...

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...

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...

arctic permafrost
2014-08-25 03:00:15

Bernie DeGroat, University of Michigan Just how much Arctic permafrost will thaw in the future and how fast heat-trapping carbon dioxide will be released from those warming soils is a topic of lively debate among climate scientists. To answer those questions, scientists need to understand the mechanisms that control the conversion of organic soil carbon into carbon dioxide gas. Until now, researchers believed that bacteria were largely responsible. But in a study published in Science...

Stanford School of Engineering New study quantifies the degree of contribution to global climate caused by slash-and-burn agriculture and wildfires, and finds bigger than expected impact It has long been known that biomass burning – burning forests to create agricultural lands, burning savannah as a ritual , slash-and-burn agriculture and wildfires – figures into both climate change and public health. But until the release of a new study by Stanford University Civil and...

Gina Hebert, Marine Biological Laboratory What do mollusks, starfish, and corals have in common? Aside from their shared marine habitat, they are all calcifiers — organisms that use calcium from their environment to create hard carbonate skeletons and shells for stability and protection. The June issue of the Biological Bulletin, published by the Marine Biological Laboratory, addresses the challenges faced by these species as ocean composition changes worldwide. As atmospheric...

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...

humgruffin
  • A terrible or repulsive person.
Regarding the etymology of 'humgruffin,' the OED says (rather unhelpfully) that it's a 'made-up word.' We might guess that 'hum' comes from 'humbug' or possibly 'hum' meaning 'a disagreeable smell,' while 'gruffin' could be a combination of 'gruff' and 'griffin.'
