radiation on the Earth’s floor, which accompany depletion in the complete column O3, led to international agreements to get rid of the production and use of compounds recognized to deplete stratospheric O3 by the 12 months 2000.37 Consequently, CFCs within the lower atmosphere are now not growing, and their fee of growth in the stratosphere is decreasing.The query thus turns into whether or not we’re seeing a response of the Antarctic ozone hole to the leveling off and decrease of stratospheric chlorine, or a reflection of climatic modifications within the stratosphere (Huck et al., 2005; Langematz and Kunze, 2006): Several factors must be thought-about: first, the Antarctic ozone gap has in all probability reached a saturated state that will persist for quite a lot of years while chlorine is decreasing (Newman et al., 2004,
