Suppose you hear someone stating that yesterday it was 7C and today it is 14C, so it's "twice as warm".

When I hear that, I cringe a bit, but these days (older, wiser, milder) I think the better thing to do is just to lightly smile or something. The 'higher status behavior' is to not always to try to "score", but instead to ignore it, unless there is some direct negative effect.
