For the 4.6 billion year claimed history of the planet, climate has managed to change and adjust for all but the last 0.000004% that we have been keeping records, with neither human supervision nor assistance.
All things considered, for the last five to seven million years, the climate has done well enough on its own, despite those pesky Homo sapiens, and the proposed solutions to alleged problems all involve economic gestures which were never necessary for the climate to function well enough before, for humans to exist and flourish, despite some self-imposed setbacks, a little 'water problem', and a plague or two.
So, NEVER would be a little too soon.
