You have hit the nail on the head!
Building a house on the sand just isn't a good idea. A famous carpenter even said so in Matthew 7:24-27.
Natural cycles of weather are being blamed on global warming all the time because only a few climatologists study long-term climate cycles, and the politically correct don't want to hear about it.
i remember that hymn from church when i was a kid about the foolish man built his house upon the sand. I was thinking about it while I was writing this and glad that you knew it as well.
