Are you being sarcastic? I was trying to avoid lingo, and what you quote is a very clumsy wording. Or is “trend line” what you are calling lingo? It’s a lousy mix of lingo and hack wording, I suppose.
I was being sarcastic. I would not consider “flukishly warm” to be a useful scientific phrase. Also, it seems like the “normal” trend is approaching the abnormal or “flukish” range, which seems — shall we say — odd.
