Definitely, any changes natural or anthropogenic would be measured and to great accuracy. I just wanted to point out that the notion of the general public, especially if conditioned to distrust scientists and authorities, not noticing changes isn’t the outlandish part. See global warming denial despite years of record setting temperatures.

Ignoring conspiracy theory stuff, people aren’t very good at perceiving changes in light levels if they happen gradually. During any solar eclipse there are wide bands where only a partial eclipse is observed. It’s pretty common for people in those bands to not notice that something has changed even with 50% occlusion.
