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

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...

Establishing a more stringent ozone standard in the U.S. would significantly reduce ozone-related premature mortality and morbidity, according to a new study published online July 18 in the journal Environmental Health Perspectives. "Abundant evidence links exposure to ozone with adverse health effects, including impaired pulmonary function, asthma exacerbations, increased hospital and emergency room visits, and increased mortality, yet the current National Ambient Air Quality Standard of...

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
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...
