Corals Evolved With CO2 20X Higher – And Temperatures 10C Warmer



A nasty one for the coral reef alarmists

Corals are a very old group of organisms, originating in the Cambrian Period more than 500 million years ago. The rugose corals are common in rocks from Ordovician through Permian age. These particular horn corals come from the Middle Devonian (397 to 385 million years ago) limestones of the Skaneateles Formation, in the classic geologic sections of the Finger Lakes country of upstate New York.
