It cites data from several years ago (before the recent spate of stories) that only talks about increases in CAT-conducive conditions, but says nothing about increases in actual incidents. The article leaves maybe the impression that any recent spike in high profile turbulence events might be a result of the changes in jet stream activity but doesn’t actually provide much justification for that. Other posts on this thread point out that there was no actual increase in reported CAT encounters that correlates with the proposed mechanism so… unclear if the article’s data says much if anything about recent media-reported CAT events.
