The Short Version
"Fogvid-24" is a conspiracy theory with no credible evidence behind it. No atmospheric testing, chemical analysis, or government documentation supports the claim that recent fog events are secret experiments. Scientists and authoritative outlets explain the phenomena as ordinary winter fog trapping existing pollutants, coinciding with seasonal respiratory illness. Even sources sympathetic to the theory concede there is "no official evidence" linking the fog to any secret operation. The existence of past programs like Operation Sea Spray does not prove current fog is engineered.
