Using the Total Ozone Mapping Spectrometer by satellite, color coding clearly delineated the hole that CFCs had created in the ozone layer. By the mid-1980s, regular studies were in place to record the effects of CFCs on the atmosphere and to try and determine how it would be possible to reverse the damage. NCSE Online, December 7, 2000.

The CFC-ozone puzzle: environmental science in the global arena. From Montreal to Kyoto: The Refrigeration Industry's Journey Toward Sustainability. Galactic cosmic ray (GCR) fluxes measured by balloons in the troposphere and stratosphere at several points in Russia, and total ozone records have been used to detect cosmic signal by linear regression analysis. It was shown that the response of total ozone is in phase with decadal variations of GCR in contrast to the assumption about ozone destruction by GCR due to the nitrogen catalytic cycle. Photochemical modelling was used to understand the situation.

Chlorofluorocarbons (CFCs) are now believed to be major contributors to the seasonal ozone depletion over the Antarctic continent. However, because they are so important to many aspects of Modern society, it would be irresponsible to immediately cease their production. The identification of suitable substitutes is difficult when issues such as toxicity, flammability, cost, environmental impact, and physical properties are considered. Unlike the simple, fully halogenated CFCs, which can only be made in the single step, there are many potentially viable routes to the alternatives, but these will require significant improvements in catalysis.

Recognition of the harmful effects of CFCs and other ozone-depleting substances led to the Montreal Protocol on Substances That Deplete the Ozone Layer in 1987, a landmark agreement to phase out those substances that has been ratified by all 197 UN member countries. Without the pact, the . would have seen an additional 280 million cases of skin cancer, . million skin cancer deaths, and 45 million cataracts-and the world would be at least 25 percent hotter. A study in early 2018 found that ozone in the lower stratosphere unexpectedly and inexplicably has dropped since 1998, while another pointed to possible ongoing violations of the Montreal pact.

Despite the fact that Molina and Rowland's theory had wide support in the scientific community, a handful of skeptics, their voices greatly amplified by the public relations machines of powerful corporations and politicians sympathetic to them, succeeded in delaying imposition of controls on CFCs for many years.
