@kelsonv Increased CO2 and methane (CH4) in the atmosphere made sunsets more orangy as well since CO2 has a higher Index of refraction than Oxygen or Nitrogen. This I looked up after seeing a stunning sunset with much yellow and orange about 45 years ago.
@AskChip I can totally imagine that changes in atmospheric composition and temperature could impact the frequency of the right types of ice crystals forming.
I also seem to recall reading that noctilucent clouds we're either increasing in frequency or starting to appear at lower latitudes over the last decade or so.
