Climate changed naturally over a long time. Thousands of years.
What we do now is happening on a fraction of that scale.
If these events are unnatural, then we are not really trying to “lock” ourselves into anything, rather trying to slow to what would have been if we didn’t screw around in the first place.
I do agree that it would be arrogant to stop natural climate change over the thousands of years that it normally took place. But we’re not doing that.
