In this part of the world (Caribbean), I have noticed no difference. I'm a person who would have noticed a difference, as I rarely miss an
opportunity to photograph a sunset. My usual pattern: Take 100-150 photographs, keep one. See, my particular obsession is the green flash.
I've taken over 12,000 photos and have captured the green flash perhaps a dozen times, and of those, I really like only six of them. It's a
somewhat wacky obsession, but harmless. I think I'd have noticed a difference in the strength and color -- at least of the setting sun, and the sun
1/2 hour before sunset. I find that I'm using the same aperature and speed.
What I HAVE noticed, though, is since this time last year, there is an everpresent "haze" for lack of a better word, that sits above the horizon.
We have no industry here, and few cars/people. I've wondered if the Saharan Dust Layer, or volcanic activity, or fires might be responsible.
This time last year and the years before, I would watch the sun set clearly, shimmering sometimes from the inverse mirage, and these days, it just
sets into a haze that is so dense I can't actually see the moment it sets. That's bad for capturing the green flash, since it USUALLY occurs the
exact moment the sun is completely behind the horizon.
Edit to add: Perhaps we are talking about the same thing, but using different words. I don't notice a difference in the daytime sun, just in the
perception of it as it approaches sundown.
