As with Punky, however, I don't know enough to say for sure (but, TBH, I don't believe anyone else on this planet does either).

I would tend to agree, but my own senses and observations make me believe that the weather is changing with increased rapidity. It may only be cyclical variation but it had better change the other way pretty quick or I will be worried.
