How much light passes through the earth's atmosphere and illuminates the moon has been an ongoing experiment for some decades now. Research has suggested a substancial decrease in light absorbing materials in earths atmosphere. If air is dirtier, then global warming has occurred slower.

Also part of this experiment is measuring light intensity of the sun. It too varies. Numerous variable. Equipment that must remain calibrated for minor variations of light intensity over generations. Complex study.
