5. Ozone and CFCs > Choloroflourocarbon (CFC) + Aerosol, refrigerators
+ Interaction w/ the ozone layer: yrs
> 1985: Ozone hole detected over Antartica
+ Started in the 70s
+ Chlorine pollutants
> Greenhouse effect: trapping gases that result in an increased temperature
+ Global warming: glaciers melting
+ Ex. Greenland
Ozone over the Antarctic 2006 5
