In 1666 London had a bit of a problem with fire, after that some building codes were introduced. Buildings made entirely from wood were not allowed and roofs had to have a parapet.

If you don't know what a parapet is, take a look up to the roofs on London's older buildings, the front wall rises up past the bottom of the roof. If there is a fire in the building then the parapet keeps the burning roof inside the footprint of the building rather than let it 'slide off' to set fire to the property on the other side of the street.

The parapet requirement did not extend to towns outside London, which makes me wonder why.

The answer to that is to see what goes on in the USA. After a natural disaster they just pick themselves up and keep going. Florida was obliterated in 2024 but nobody cared after a fortnight. Same with the current wild fires, nobody will care next week, it will be forgotten, even though having one's home destroyed might be considered deeply traumatic.

I think that the key to change is to not have too many natural disasters, ideally nobody has living memory of the last fire/flood/earthquake/pandemic/alien invasion/plague of locusts so that there is no point of reference or 'compassion fatigue'. Only then can there be a fair expectation of political will and the possibility of change.
