Scientists from NASA’s Jet Propulsion Laboratory in Pasadena, California have managed to show via direct satellite observations that the worrisome ozone hole in the Antarctic region is slowly healing back to suggest that the ozone-depleting chlorine levels are slowly declining.
The ozone layer could be saved due to the worldwide ban on the use of chlorofluorocarbons which contains harmful chlorine that is responsible for the depletion of ozone layer. In comparison with records obtained in the year 2005, the overall ozone depletion rate has been reduced by 20 percent. The initial reading regarding the rate of depletion pertaining to high chlorine level was measured by NASA’s Aura satellite during the winter season in Antarctica.
The lead author of the study, Susan Strahan, an atmospheric scientist belonging to NASA’s GSFC (Goddard Space Flight Center) in Greenbelt, Maryland explained that it can be clearly observed that the chlorine level near the ozone layer is …
