It's something people don't realize. We may be a scourge on the Earth, but we're still nowhere even near the top of the list of worst things to happen to this planet.
As the other reply brought up, Theia crashing into Earth. Flood basalt events. The Chicxulub impact.
We may be able to cause some real awful shit, but we still are nothing compared to what the forces of nature can produce. And just to clarify, I'm not saying this to in any way downplay the seriousness of climate change, or that we should do nothing about it.
