Antarctic Ozone Hole Will Get Larger In 2008 - U.N.
The United Nation weather agency, on Friday, reported that the hole in the ozone layer over Antarctica may increase this year than in 2007.
The ozone layer protects the earth from harmful ultra violet rays which could cause skin cancer. The size of the ozone hole ultimately depends on the weather conditions which presently is as big as North America.
In latest Ozone bulletin, the World Organization said, “As the sun returns to Antarctica after the polar night, it is expected that ozone depletion will speed up.”
If large amounts of chlorine and bromine remain in the atmosphere it could cause harmful holes in the protective layer of the ozone layer. This all is happening because the use of ozone-depleting chlorofluorocarbons (CFCs) has decreased.
“It is still too early to give a definitive statement about the development of this year's ozone hole and the degree of ozone loss that will occur," the WMO added.
