David Grinspoon Quote
Some unknown process was, it seemed, protecting CO2 from the anticipated destruction. This unexpected and strange stability presented a puzzle, which was solved by Michael McElroy at Harvard and Ron Prinn9 at MIT, two atmospheric scientists whose careers have straddled earth and planetary science. The answer, they found, lay in the highly reactive element chlorine. Even minuscule amounts of chlorine in such an environment wreak outsize havoc on oxygen compounds, catalyzing their destruction and reconstituting CO2. Modeling Venus in the early 1970s, McElroy and Prinn showed that you would not expect ozone to survive in an environment where stray chlorine atoms were running
