Hence why the term Man Made Climate Change is used to refer to the impact humans are having on accelerating climate change.
No climate scientists are arguing against the natural climate change, they're pointing out that we are massively accelerating it.

Gases that trap heat are measured as CO2e aka Carbon Dioxide Equivalent, referring to the amount of heat they trap compared to CO2.
Milankovitch cycles take place over 10s of thousands of years, we wouldn't see the level of climat change we're seeing...
Yes, changing it over the course of hundreds of thousands of years. We've seen the climate change over decades, caused by human activity.
Hence the name "Man Made Climate Change".
Perhaps actually research climate change properly.
