Some Hope: New Study Showing Ozone Recovery Hailed As Model For Tackling Climate Crisis
By Jake Johnson Common Dreams (1/5/18) Hailed as an example of how concerted global action can help solve a planetary crisis, a new study conducted by NASA scientists documented the first direct evidence that an international effort to ban chlorofluorocarbons (CFCs) has led to the recovery of the Antarctic ozone hole. Published in the journal Geophysical Research Letterson Thursday, the study uses satellite observations to demonstrate that the decline in atmospheric chlorine that resulted from the implementation of the Montreal Protocol, enacted in 1989,has led to “about 20 percent less ozone depletion during the Antarctic winter than there was in 2005—the first year that measurements of chlorine and…
