Fair enough - I was quibbling, to a large part because:

1. The weather in my home region has gotten weird compared to my childhood - many mild winters and summer droughts, for example.

2. An Alaskan on DeviantArt a while ago wrote a prose piece about how she was always freezing, never warming enough in the summer to withstand the following winter ... and prefaced it with a matter-of-fact note about how that wasn't the case in recent years.

Hence, when you commented that "[i]t's not like a normal person, can observe such changes", that seemed to contradict my own experiences. But given the prior attitude effect, my experiences should probably be discounted a fair bit.
