Funny thing is those that believe in catastrophic warming, their initiatives are akin to rearranging the deck chairs on the Titanic (maybe not the best analogy to use today). Let's be perfectly honest, the only way to lessen humans' impact on the environment, if the situation is as severe as they say, would be to limit human reproduction. Anything else would just be window dressing and virtue signaling.
Fortunately, it not as dire as the climate cult claims and like you said climate has changed through the history of the earth with or without humans. It's just that now science has become so arrogant it thinks its ideas can prevent climate change (just like they thought their ideas could stop Covid).
IMO I think the best thing we could do now for our environment would be to move to nuclear energy. Clean, safe, efficient and requires a very small footprint as compared to renewables.
