Brett Smith for redOrbit.com - Your Universe Online In the keynote address at the 244th National Meeting & Exposition of the American Chemical Society in Philadelphia, Nobel Laureate Mario J. Molina stressed that the latest scientific evidence has only strengthened the link between human activity and extreme weather events and global warming. Molina has some experience in working with human-atmospheric interactions on a global scale. The University of California, San Diego professor...

Summer contest aims to raise awareness about air quality in the region Pittsburgh, PA (PRWEB) August 14, 2012 A summer contest offers residents of Pennsylvania the chance to win prizes for guessing when the Steel City´s “First Clean Air Day of Summer” will occur. Much like a television weatherman might ask viewers to pick the first snow day of the year, the contest asks people to submit their guess for the First Clean Air Day of Summer. The contest is part of an ongoing...

Atmospheric Compound Linked To Climate Change, Human Health
2012-08-09 05:34:42

April Flowers for redOrbit.com - Your Universe Online An international team of researchers has discovered a surprising new chemical compound in Earth's atmosphere that reacts with sulfur dioxide to form sulfuric acid, which is known to have significant impacts on climate and health. The team, led by the University of Colorado Boulder and the University of Helsinki, found that the new compound, a type of carbonyl oxide, is formed from the reaction of ozone with alkenes. Alkenes are a...

Most of the world's population will be subject to degraded air quality in 2050 if man-made emissions continue as usual. In this 'business-as-usual' scenario, the average world citizen 40 years from now will experience similar air pollution to that of today's average East Asian citizen. These conclusions are those of a study published today in Atmospheric Chemistry and Physics, an Open Access journal of the European Geosciences Union (EGU). Air pollution is a major health risk that may...

Air Pollution Increases Worldwide

Atmospheric model calculates changes in air quality over the coming decades Hot summer days cause in large cities very seldom great happiness among inhabitants. On those days the air is highly polluted with automobile and industrial emissions what makes breathing difficult and unhealthy. According to the latest calculations of Max Planck scientist Andrea Pozzer this scenario could become true for most of world population in 2050 if no counteractive measures are taken. Especially China,...

The destruction of atmospheric ozone can take place within newly forming Polar Stratospheric Clouds (PSCs), which serve as the battleground for manmade chlorofluorocarbons (CFCs) to attack and destroy ozone. These clouds form when clusters of frozen water "pick up" other atmospheric molecules such as methane, nitrogen oxides, and water molecules, similar to the way a snowball's girth increases as it rolls down a mountainside. Most previously established atmospheric models have assumed that a...

Summer Storms Cause Ozone Depletion In United States
2012-07-27 09:49:29

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...

HARRISBURG, Pa., July 25, 2012 /PRNewswire-USNewswire/ -- The Department of Environmental Protection announced today it will begin forecasting on Aug. 1 for ozone for eight additional areas across the state, which will help to protect residents who have health concerns that could be worsened by poor air quality. The new forecast areas are: Altoona; Erie; Johnstown; Scranton/Wilkes-Barre; State College; Williamsport; Mercer County; and Indiana County. "This summer's record heat...

HARRISBURG, Pa., July 23, 2012 /PRNewswire-USNewswire/ -- The Department of Environmental Protection announced today it has started a long-term, one-year air monitoring study of Marcellus Shale development. The study in Washington County will measure ambient airborne pollutants in an effort to determine potential air quality impacts associated with the processing and transmission of unconventional natural gas. "We operate on facts and sound science, and this study will provide us with data...

Atlantis launched from Kennedy Space Center on November 3, 1994 at 11:59 AM EST and landed at Edwards AFB on November 14 at 7:33 AM PST. The shuttle orbited 174 times at an altitude of 164 nautical miles at an inclination of 57 degrees and travelled 4.5 million miles. The mission lasted 10 days, 22 hours, 34 minutes, and 2 seconds. This mission further advanced efforts to collect data about sun's energy output, chemical makeup of the Earth's middle atmosphere, and how these factors affect...

Earth's Atmosphere

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...
