And though Dr. Lovelock identified the presence of CFCs in the atmosphere, he also reasoned that at concentrations in the parts per billion, they posed “no conceivable hazard” to the planet.

By analysing the atmosphere of Mars ... With it, Lovelock conducted some of the earliest studies of CFCs and suggested how sulphur from marine algae circulated worldwide and played a part in ...
