> Old people often make fact-free claims about how things used to be.

It's fun, because if there is something that is really a cliché is people complaining that the weather is not what it used to be. This has been going on for far longer than there has been any talk of climate change. So every time I hear someone saying that you can see climate change is happening because the weather is not what it used to be, I take it with a double pinch of salt.

Alternatively, the existence of the cliche might suggest that (some) climate change is always happening, just on a timescale that makes old people complain, and everybody else just be incredulous.
