>CO2 emissions and pollution are vastly reduced
>Air pollution drops so much people in Asia can see blue skies and the Himalayas in 50 years
That's all nice, but both air pollution and human fossil fuel burning are on the short-term side of time scales. Sure, NO2 columns as seen by TROPOMI etc., drop almost instantly when people stop driving their cars, but it'll also go up as soon as people start commuting again. Same for most other anthropogenic carbon emissions. Unless the current perturbation induces some more long-term or sysematic change, it'll just bounce back, but will be great for some scientific case studies.
