This cannot be true, considering the superplumes of the cretaceous.

You are correct; the Earth has experienced CO2 rise of this speed before (as far as we know). But not for millions of years, and each time would have been a mass extinction event. https://earth.org/data_visualization/a-brief-history-of-co2/

Just because it's happened before (millions of years ago) doesn't mean it's not serious.
