Overall, the lunar night temperature difference was around 8–10 Kelvin. …
The reason for the dip, according to the team, is the amount of radiation received from the Earth. During the lunar night on the near side, the Moon receives its radiation as it is reflected off the surface of the Earth. As human activities changed, and fewer pollutants were put into our atmosphere, this had a knock-on effect, with less radiation reflected toward the Moon. And so, COVID-19 lockdowns appear to have, inadvertently, briefly made the surface of the Moon colder.
I remember when the lockdowns first hit. After about a month, the skies were clearer. I lived in the suburbs at the time and it was subtle but noticable. This was his things were supposed to be. Little traffic, less noise and smog pollution.
Return to office mandates killed it all.
