By the same geologic record I can tell you the climate was not hospitable for the current diversity of life the last time carbon dioxide and other ‘greenhouse gas’ concentrations were elevated to the concentrations we are projected to achieve. Hope you enjoy mass extinctions, which that very same geologic record indicates happen when massive climate change occurs.
Welcome to the anthropocene era, as geologists already describe this era in the geologic record.
Categorically declaring those effects to be summarily equal isn’t science either, its sophistry.
