What is the relationship between global dimming, value of solar constant, temperature, and growth of plants?

Question

I am interested in the amount of visible light being emitted by the sun, as a possibility of a factor in global dimming. I have read (somewhere) that duing the Middle Ages the full moon was bright enough that hunting was done during full moon. (Moon reflects the light of the sun)

Answer 1

There is really no relationship linking all those things.

Global dimming has more to do with dust and clouds than anything else.

The solar constant is, well, constant. Not really, but the variability is quite small and not well measured in the past.

World temperature is too complex a thing to measure. I do not believe reports that the world temperature is higher now than ever before. You cannot just take a bunch of reported temperature readings and average them. It just isn't that simple.

The full Moon is still bright enough to hunt by today. It hasn't really changed in thousands of years. Heck, I can read by the light of the Full Moon!

You may be thinking about efforts to measure the solar constant by observing the brightness of the Moon. But that has nothing to do with temperature or plant growth.
