The cynicbin me says that the lack of action on climate change, reform of pensions systems, migration and so on is mainly caused by old people always voting the conservative, reactionary and "social" democratic parties. Now the earth finds it way into equllibrium by taking these people out of the voting process first.

In Germany we can't even find a way to share the costs and benefits of installing better heating in appartement buildings, because the landlird lobby is succesful in argueing against paying part of the CO2 price, despite controlling which heating system is installed. So i am optimistic, that mandatory rules for ACs will only come, when old people already had to leave the cities, or died off in the heat waves.
