Ozone Hole News Stories
Current Ozone Hole News Events, Discoveries and Articles
New simulation shows consequences of a world without Earth's natural sunscreen
Nearly two-thirds of Earth's ozone is gone -- not just over the poles, but everywhere. The infamous ozone hole over Antarctica, first discovered in the 1980s, is a year-round fixture, with a twin over the North Pole. The ultraviolet (UV) radiation falling on mid-latitude cities like Washington, D.C., is strong enough to cause sunburn in just five minutes. (2009-03-19)
2008 ozone hole larger than last year
The 2008 ozone hole - a thinning in the ozone layer over Antarctica - is larger both in size and ozone loss than 2007 but is not as large as 2006. (2008-10-08)
Drier, warmer springs in US Southwest stem from human-caused changes in winds
Human-driven changes in the westerly winds are bringing hotter and drier springs to the American Southwest, according to new research from The University of Arizona in Tucson. (2008-08-19)
Computer models show major climate shift as a result of closing ozone hole
A new study led by Columbia University researchers has found that the closing of the ozone hole, which is projected to occur sometime in the second half of the 21st century, may significantly affect climate change in the Southern Hemisphere, and therefore, the global climate. (2008-06-13)
Climate Models Overheat Antarctica, New Study Finds
Computer analyses of global climate have consistently overstated warming in Antarctica, concludes new research by scientists at the National Center for Atmospheric Research (NCAR) and Ohio State University. (2008-05-08)
Ozone hole recovery may reshape southern hemisphere climate change
A full recovery of the stratospheric ozone hole could modify climate change in the Southern Hemisphere and even amplify Antarctic warming, according to scientists from the University of Colorado at Boulder, the National Oceanic and Atmospheric Administration and NASA. (2008-04-25)
2007 ozone hole 'smaller than usual'
The ozone hole over Antarctica has shrunk 30 percent as compared to last year's record size. According to measurements made by ESA's Envisat satellite, this year's ozone loss peaked at 27.7 million tonnes, compared to the 2006 record ozone loss of 40 million tonnes. (2007-10-04)
NASA keeps eye on ozone layer amid Montreal Protocol's success
NASA scientists will join researchers from around the world to celebrate the 20th anniversary of the Montreal Protocol, an international treaty designed to reduce the hole in Earth's protective ozone layer. (2007-09-14)
By ice floe to the North Pole
At the end of August, an unusual expedition under Russian leadership will leave for the Arctic Ocean. One of the participants is Jürgen Graeser of the Alfred Wegener Institute for Polar and Marine Research, one of the research centres of the Helmholtz Association. (2007-07-23)
B12 Is Also an Essential Vitamin for Marine Life
B12 - an essential vitamin for land-dwelling animals, including humans - also turns out to be an essential ingredient for growing marine plants that are critical to the ocean food web and Earth's climate, scientists have found. (2007-05-21)
