Dubai's Floods Weren't Caused by Cloud Seeding

I think it’s both: climate change as the origin of the freak thunderstorm and their absolute lack of working sewers and drainage systems is the cause of all that water accumulating to the point that we all saw in photos and videos.

You know the answer, it was climate change.

Or if you want to be more pedantic, the cause of the flood is a failure to adapt public infrastructure to changes in rainfall intensity caused by the economic system Dubai is desperately fighting to perpetuate.

Also ill-equipped to deal with human waste.

It's as scary as you'd expect from a castle in the sand

No not really. If rainfall events are rare enough. It is like snow. Being equipped is trivial and no challenge at all. Still many locations fail to do it.

Impurities trigger nucleation, i.e. the formation of droplets (or more or bigger droplets, depending on the situation), in situation where the atmospheric conditions wouldn't cause them to form otherwise, thus more rain falls.

It help create tiny droplets that grow as they fall.
