Latest Polar stratospheric cloud Stories
Scientists have unexpectedly identified a high-altitude methane ice cloud floating above the north pole of Saturn’s moon Titan – a cloud that is similar to the exotic clouds found far above Earth’s poles.
A combination of extreme cold temperatures, man-made chemicals and a stagnant atmosphere were behind what became known as the Arctic ozone hole of 2011, a new NASA study finds.
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.
Check the fine print on many cans of hairspray or shaving cream these days, and you’ll probably find a reassurance that the product you are holding contains “No CFCs or chemicals known to harm the ozone layer.”
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?
Unusually low temperatures in the Arctic ozone layer have recently initiated massive ozone depletion.
The 2008 ozone hole â€“ a thinning in the ozone layer over Antarctica â€“ is larger both in size and ozone loss than 2007 but is not as large as 2006.
The evils of global warming and ozone depletion are competing problems, at least in Antarctica, the results of two new studies suggest. Schemes to pump sulfur into the atmosphere to counteract global warming might help cool the Earth, but they could also cause problems at the poles, scientists warned today.
Rare, mother-of-pearl colored clouds caused by extreme weather conditions above Antarctica are a possible indication of global warming, Australian scientists said on Tuesday.
