There are a lot of destructive pests on earth. Amazingly enough, all created by Mother Nature.
Still, the point I was making was that no one single cause may be responsible for the flood. Case in point, the fire out in California. Most people associate forests fires with someone being careless with a match. Could also be a drought. Or even the opposite, a lightning strike. Over grown brush or dead leaves. etc. A flood, has been known to be started by something as innocuous as a beaver dam. Or as I mentioned leaves or dead tree limbs blocking a drainage ditch or a river, creek, or stream. I've seen those last two, by the way.
Disasters are *never* single things. (I say this as an engineer where failure mode analysis was part of the job)
Disasters are where a whole bunch of things go wrong in a negatively reinforcing way.
The other fun thing is "we don't want a single point of failure". Actually we do. We want everything to fail such that it comes down to a single place. Because then we know where to put the safety net
What we don't want is a situation where our safety net fails. This is why we use a safety factor in calculations. aka: ignorance factor. The more we know, the lower it can be. And the more expensive it becomes. Military vs commercial planes is a good example. Generally, you want it low to push performance higher, while still maintaining the same risk. That costs.
A text book example of this is the Titanic. The real problem was, the safety net was insufficient. If any of the contributing factors to the disaster happened even slightly differently, the disaster would not have happened. If the average speed of the ship had been a very tiny fraction of a percent higher or lower, it would not have happened. If they had left port even a few seconds earlier or later. If the water currents had been even slightly different over a span of months, the iceberg wouldn't have been in that exact spot. If the bulkheads had been welded slightly differently. Etc., etc.
Resiliency is something else.
But, back on thread: Warm. Bordering hot (in the sun). Alternating with cool, bordering on cold. Sometimes alternating between extremes in under an hour. 10º drop in 15 minutes, one day this week. Winds from zero to hurricane. Rain from drenching (rarely) to cloudless. Spring in Sydney
