Now the flood was on the earth forty days. The waters increased and lifted up the ark, and it rose high above the earth.
(Genesis 7:17) NKJV
If you’re following along then you may notice that this description of the Ordovician is very similar to the description of the Cambrian. There are many ways you can describe a world-wide flood without saying the words “world-wide flood.”
Erosion and deposition of sediment happens as the result of precipitation and flooding. “Warm, mild climates” is a way of implying that warm temperatures caused increased evaporation from the oceans.
Increased evaporation led to increased precipitation. Increased precipitation was necessary for sediment to be eroded, transported and deposited. “Warm, mild climates” is a microcosm of circular reasoning that tells us that increased precipitation was necessary to deposit Ordovician sediment. Increased precipitation is science jargon for heavy rain. Like, 40 days and nights of heavy rain.
Has the penny dropped?
