To understand and quantify the ocean's sponge - like capabilities, the researchers used the two independent models of Atlantic Ocean currents together with shipboard observations of chlorofluorocarbons as a starting point. (giss.nasa.gov)
Long - lived chlorine species, such as chlorofluorocarbons (CFCs), led to depletion of the stratospheric ozone layer in the 1980s, most drastically seen in the Antarctic. (sciencedaily.com)
Signed in the late 1980s, the protocol saved the ozone layer by ending the use of chlorofluorocarbons in refrigerants, household goods, and industrial products. (chimalaya.org)
