The Ordovician Ice Age

Some 440 million years ago, global temperatures dropped sharply and the Earth entered in an Ice Age.

The Ordovician Ice age was so severe that it triggered a massive extinction event that caused the loss of 85% of marine animal species and 26% of animal families.

All this happened at between 8 and 12 times the current CO2 levels. Not by warming, but by cooling.

This completely contradicts the hypotsis promoted by the IPCC, the UN and your national government that CO2 warming is the main climate driver and that even just doubling the current CO2 levels would lead to catastrophic global warming. Exactly the opposite happened 440 million years ago.
