“ extrapolated the chlorine numbers from fifty years ago, before satellites were available to measure that stuff.”
Was there abdo-lutely no way of making those measurements in the 1960s?
Weather balloons could take very high altitude air samples.
But you must remember that despite what the modelers assume the atmosphere is not a homogeneous mixture and sampling methods, efficiencies of detection and numbers of samples taken are drastically different 50 years hence.
The central planners in the USSR used those types of models to allow Khruschov to say that they would ‘bury us’ economically.
Of course, Democrat economists readily agreed that, yes, that’s what the models showd so we had to change.
Of course, there’s not USSR anymore.
