In the spring of 2011, the ozone layer that protects us from harmful levels of ultraviolet rays has shown a record loss in the Arctic region, according to the U.N. weather agency. The continued presence of ozone-depleting substances in the atmosphere coupled with a very cold winter in the stratosphere is to blame. Although an international agreement from 1987 called the Montreal Protocol has successfully reduced the production and consumption of these ozone destroying chemicals, the long...

ESA's Envisat satellite has measured record low levels of ozone over the Euro-Atlantic sector of the northern hemisphere during March. This record low was caused by unusually strong winds, known as the polar vortex, which isolated the atmospheric mass over the North Pole and prevented it from mixing with air in the mid-latitudes.This led to very low temperatures and created conditions similar to those that occur every southern hemisphere winter over the Antarctic.  As March sunlight...

Arctic-wide measurements verify rapid depletion in recent days Unusually low temperatures in the Arctic ozone layer have recently initiated massive ozone depletion. The Arctic appears to be heading for a record loss of this trace gas that protects the Earth's surface against ultraviolet radiation from the sun. This result has been found by measurements carried out by an international network of over 30 ozone sounding stations spread all over the Arctic and Subarctic and coordinated by the...

Wyoming is looking more like Los Angeles because of the recent boom in natural gas drilling, reports The Associated Press (AP). People are now complaining of watery eyes, shortness of breath and bloody noses because of ozone levels that have exceeded what people in L.A. and other major cities deal with. In the Upper Green River Basin, some wonder if they have made a bargain with the devil by having gas drilling go strong again.  Because of this, Wyoming enjoys one of the nation's...

By studying collections of a marine bryozoan that date back to a famous 1901 expedition to the South Pole, researchers have found that those organisms were growing steadily up until 1990, when their growth more than doubled. The data, reported in the February 22 issue of Current Biology, a Cell Press publication, provide the highest-latitude record of a century of growth and some of the first evidence that polar carbon sinks may be increasing. The bryozoan in question, known as Cellarinella...

Brightly-lit Cowboys Stadium during Sunday's Super Bowl XLV may symbolize one of the hottest new pieces of scientific intelligence about air pollution: Researchers have discovered "” in a classic case of scientific serendipity "” that the bright light from sports stadiums and urban street lights may boost daytime levels of ozone, a key air pollutant in many heavily populated areas. That's among the topics included in a broader article about the chemistry of air pollution in the...

According to a study by U.S. scientists, bright city lights exacerbate air pollution. Their research indicates that the glare thrown up into the sky interferes with chemical reactions. These reactions would normally help clean the air during the night of the fumes emitted by vehicles and factories during the day. The researchers presented their findings at the American Geophysical Union meeting in San Francisco. Nature uses a special form of nitrogen oxide, known as nitrate radical, to...

Geophysical phenomena such as the dynamics of the atmosphere and ocean circulation are typically modeled mathematically by tracking the motion of air or water particles. These mathematical models define velocity fields that, given (i) a position in three-dimensional space and (ii) a time instant, provide a speed and direction for a particle at that position and time instant. "Geophysical phenomena are still not fully understood, especially in turbulent regimes," explains Gary Froyland at the...

Word of the Day
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED. 'Copp' is still found in the word 'cobweb.'
