Chuck Bednar for redOrbit.com - Your Universe Online The layer of gas that protects us and all life on Earth from the Sun’s harmful ultraviolet radiation may be on the road to recovery, but as the world commemorates World Ozone Day on Tuesday, officials emphasize there is still much work to be done. Starting in 1994, the UN Assembly proclaimed that September 16 would be the International Day for the Preservation of the Ozone Layer (or, alternatively, World Ozone Day). The date was...

Antarctic Ozone Hole Smaller This Year
2013-10-26 05:52:20

[ Watch The Video: Daily Ozone Hole for 2013 ] redOrbit Staff & Wire Reports - Your Universe Online The Antarctic ozone hole, a seasonal phenomenon that starts forming during the month of August was slightly smaller this year than it was on average over the past several decades, NASA satellite data has revealed. The average size of the ozone hole in September-October 2013 was 8.1 million square miles (21 million square kilometers), the US space agency reported on Friday. In...

Antarctic Ozone Hole Is Shrinking
2012-09-15 08:17:08

April Flowers for redOrbit.com - Your Universe Online The United Nations reported Friday that the hole in the ozone layer is expected to be smaller this year over the Antarctic than last year. They claim this illustrates how a ban on harmful substances has slowed ozone depletion. The ozone layer in the Earth's atmosphere contains relatively high concentrations of ozone (03).  This layer is found mainly in the lower portion of the stratosphere and absorbs 97 — 99% of the Sun's...

Summer Storms Cause Ozone Depletion In United States

Lawrence LeBlond for redOrbit.com - Your Universe Online It was in the 1970s that the British Antarctic Survey discovered a hole in the ozone layer above the Antarctic Circle, and in 1985, when the first measurements were taken, researchers were dumbfounded by the dramatic drop in ozone levels. The concern was so great that it eventually led to the ban of all products containing chlorofluorocarbons (CFCs), which were confirmed to be the root cause of the ozone depletion. Fast forward...

New Data Shows Antarctic Ozone Hole Still Remains
2011-10-20 13:06:41

[ Watch the Video ] The Antarctic ozone hole, which yawns wide every Southern Hemisphere spring, reached its annual peak on Sept. 12. It stretched to 10.05 million square miles, the ninth largest ozone hole on record. Above the South Pole, the ozone hole reached its deepest point of the season on Oct. 9, tying this year for the 10th lowest in this 26-year record. NASA and the National Oceanic and Atmospheric Administration (NOAA) use balloon-borne instruments, ground-based instruments...

CFC's the Real Reason for Ozone Loss?
2011-10-13 03:04:52

Op/ed By Kevin Roeten (roetenks@charter.net) How many individuals and corporations have lost money and jobs over theoretical ozone depletion? Why have natural variations never been considered as a possible reason for seasonal ozone loss? With ozone (O3) depletion, millions were (and are) convinced that chlorofluorocarbons (CFC´s), and certain brominated compounds (Halons), were responsible. Due to their theorized Ozone Depletion Potential (ODS), the most stable non-toxic refrigerants,...

Scientists Detect First-Ever Arctic Ozone Hole
2011-10-03 05:19:46

A team of international researchers, led by NASA scientists, has discovered an unprecedented loss of protective ozone in the atmosphere above the Arctic this year, according to various media reports published on Sunday. That phenomenon, according to an AFP article, has led to the formation of an ozone hole five times the size of the state of California. It marks the first time that ozone loss in the Arctic region has matched ozone loss above Antarctica, both they and Postmedia News are...


Word of the Day
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.'
