The university where i studied uses high temperature cooling since a few years. The weather on Germany ranges to quite high temperatures, but according to the tech stuff they only need active (as in AC) cooling for the higher end of the 30 degrees. The technology is quite fascinating.

I lived in Munich many years ago, but if the temperature ever went to the high thirties for more than a day we'd expect the end of the world :-)

Speaking from a UK perspective global warming is now noticeable, hot days are hotter and there's more likely to be a heat wave, and that's changed in the last decade.

I assume Germany is the same, many years ago really is different to today.

For sure. Everywhere. Even observationally, we just all know it's hotter, or wetter, or colder - it's all way more extreme in all dimensions.

Yeah early this year I've had the coldest winter in years and now the hottest summer in years.

Come now to south of Germany. We are in the middle of a 10 days heatwave at 35 degC on average.

38°C in Mannheim today. Might go above 40°C on Saturday, which never happened here before.

Good grief! That's crazy.
