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...

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...

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...

Arizona A/C Service Contractor American Cooling and Heating Explains the Phaseout of R22 and Gives Advice on How to Handle it Phoenix, Arizona (PRWEB) July 10, 2012 GWP - Global Warming Potential is a relative measure of how much heat a greenhouse gas traps in the atmosphere, R22 has a high GWP, is harmful to the ozone layer and is being phased out because of these facts. As the federally mandated phaseout of Refrigerant-22, also known under the brand name Freon, leads to lower production...

Direct Evidence That Elemental Fluorine Occurs In Nature
2012-07-05 13:35:43

200-year long dispute over smelly mineral from Upper Palatinate resolved Fluorine is the most reactive of all chemical elements and calls for extremely careful handling. It is so aggressive that glass laboratory instruments cannot resist it and even bricks burn when exposed to fluorine gas. Yet elemental fluorine has numerous industrial applications including corrosion prevention or fuel tank diffusion barriers and it is used for the production of sulphur hexafluoride, which serves as...
