"Cold periods have caused mass extinctions - not c02."

Researchers have discovered two of Earth’s ancient mass extinctions wiped out life on the planet in a similar way to one another and that both were associated with global warming conditions.

Research led by Curtin University in Perth, Western Australia, and published in Geology, demonstrated the cascade of events during the fourth largest extinction, at the end of the Triassic period 200 million years ago, were remarkably similar to those of the largest extinction that occurred at the end of the Permian 250 million years ago.

As if only human life has been affected by weather, animals and plants have thrived during higher co2 times.

True. But mass extinctions occurred during the period when the CO2 level went up. The fact that not all life died out, adapted to the higher temperatures and rebounded during the new climate shouldn't be surprising.
