When the outbreak first started gaining worldwide attention there was a series of before and after satellite photographs showing the dramatic decrease in smog levels around major Chinese manufacturing cities. Pretty amazing photos if I recall correctly.
Now that there are no new cases in China and things are back to normal do they have new photographs showing the return to normal smog levels?
I haven’t seen any. Did you look at the traffic congestion? It it under 5% of normal—not 5% below normal...5% OF normal.
