(I'm at a standstill at work today until someone else fixes an issue)
Putting aside the larger point that 25 years worth of local weather data is not a basis for conclusions about
climate change, let's look at your 25 year claim. Culver city, the last 25 years, August 10 highs and lows.

If there's ANY trend to be gleaned from that, it's that any cooling you may perceive seems to be a correction back towards the mean after a slight rise.
Of course, none of this proves there ISN'T climate change happening. But it certainly doesn't prove there IS.
Trying to shove local weather data in the face of climate change deniers is pointless, because they can just as easily shove opposing local weather date right back at you because local weather data is NOT the data that indicates anything either way when talking climate change.
