Not quite hundreds of years - if you look at the data anthropogenic climate change wasn’t really there yet before 1970.

Edit: For those saying “don’t blame boomers” that’s not the point being made here. Yes people have destroyed nature since the beginning of civilization but it wasn’t MATERIAL at a global carbon emissions level until second half of last century.
