I remember 60s weather pretty well one thing I did notice was in the 66/ 67 there suddenly was a lack of snow in fact in December christmas time I remember for a change it being sunny! Also we ceased getting the fog to the extent we had it before.
I see it being because of the clean air acts taking affect gradually and also a lot the old type factory chimneys were being demolished and replaced with high velocity chimneys which were much narrower which meant the gases left chimneys at faster speed and therefore travelled further which then made it some other countries responsibility what can be said of 60s is its decade that the weather patterns changed
