Ozone Hole

OZONE HOLE ПОЯ ANTARCTIC OZONE HOLE IS A RECORD BREAKER I he ozone layer acts to protect life on Earth by blocking harmful ultraviolet rays from the sun. The "ozone hole" is a severe depletion of the ozone layer high above Antarctica. It is primarily caused by human-produced compounds that release chlorine and bromine gases into the stratosphere. NOAA scien- tists report that the 2006 ozone hole in the polar region of the Southern Hemisphere has broken records for area and depth. Observations by NOAA's satellites, such as the TOAST sensor images shown below, document the changes in the ozone hole. In the critical layer of the atmosphere between 8 and 13 miles, nearly all of the ozone has been destroyed. However, large declines in the ozone hole, such as the one in 2006, are common year- to-year variations caused by Antarctic stratosphere weather fluctuations. Overall, the ozone hole is esti- mated to decrease annually very slowly in area by about 0.1 to 0.2 percent for the next 5 to 10 years.
