The more people install air conditioning the more energy we use, warming up the world even more, requiring even more AC units to be activated.
Energy used in private AC is very small fraction of total bill and has no meaningful effect on the climate. Compare with data centers running entirely off grid, powered by tens of massive gas generators.

You're looking at the figures today, not the figures when every house in the country has to install it.
In Florida, HVAC accounts to 40% of energy bill of the household.
40% of 15% is not that much, even if everyone is using AC.

Most heat pumps in Germany are air to water which can't be used as air conditioner. Mainly, the existing plumbing is used.
Why wouldn't air/water be able to cool the air? It'd just output hot water instead of hot air

Oh that is interesting. A greek guy I know said to me that cities 'radiated heat' some years ago and I kinda didn't believe him. Localised to alleyways etc the effect can probably be even worse.
The urban heat island effect isn't to do with AC specifically. It's a mix of tarmac absorbing heat during the day then re-radiating it at night, a higher population density and a higher density of machinery. The night time re-radiation has the effect of bringing the min closer to the max readings, and so making it look as if temperatures are going up, even when max temps aren't changing much. The same effect can't be…

Today residential use amounts of 15% energy used in USA, and 40% of electricity use. In Florida, HVAC accounts to 40% of energy bill of the household. 40% of 15% is not that much, even if everyone is using AC.
Just because you can make it look small by focusing on the percentage doesn't change that. At the end of the day it means, if we accept these numbers, that the total national energy usage would go up by around 7%. That then gets multiplied across France Germany, The Netherlands, Poland, Belgium, the UK & Ireland etc., to the point that the total power usage is as if we suddenly had another entire country.
And keep in mind while considering any of these numbers that our current 100% is already much higher than where we need to be at to avoid widespread ecological disasters. We need to be reducing our usage not saying "well it's only a few percent more."

I don’t know what you’re talking about. I’ve had these temperatures in summer as a child in the same location I am now.
Oh yes 2003, how about a 2003 every year? I'd expect a bit more statistical knowledge here...
Used to be every 2 years in my childhood.
Both the duration and average and maximum temperature are all lower now compared to my childhood.
Is that enough statistics for extreme temperatures not being that extreme compared to previously? At least in my country?

My God the radicalisation funnel produces some utter brain rot. Unsubstantiated accusations, slippery positions designed to distance your moral culpability in the consequences of your actions. Seriously, read yourself sometime.
The radicalisation of… check notes… being able of affording meat and a car.
