You think multiple people cannot be wrong about something as subjective as recollection of the weather? They could even be right, but not representative, and thus pretty meaningless. If you think the man is tampering with weather data, by all means, read up on empirical meteorology, get together a group of geographically distributed individuals, and verify away. Or join one of the existing groups. But I think temperature and rainfall are already pretty bulletproof, frankly.
