Which is precisely why I used it...conceivability (when not backed-up with so much as a shred of evidence) is little more than conjecture - even when it does hint at what we all want to hear?
Maybe the anomalous amount of spent rocket fuel was what caused the 1960s' winters to be cold...? Though technically 'conceivable', I agree that it is almost certainly nonsense. But, can the same not - based on the (lack of) evidence - also be said of so-called lunar and solar effects...after all, 1947 not only gave us the snowiest winter in living memory, it also saw a wonderful summer - all at the peak of the sunspot cycle?
As far as teleconnections are concerned, however; I think that all we need do is find them and verify them...
