The OP did not say we need to reel it in over the course of only 1 or 2 generations.
They said that, until we do, the situation will remain precarious. I'm sure you can imagine an (admittedly extremely improbable) scenario where the global population shrinks to 4 billion over the course of 500 years without significant injustice being done to anyone to achieve the shrinkage.
Sadly, when it comes to greenhouse-gas-driven climate change, the timeline on which we will succeed or fail to address the problem is too short for any population size adjustments to be of any use (unless you want to achieve the adjustment by mass murder).
This is probably the source of any misunderstanding between you. The OP is not contemplating mass murder, but does not appreciate the urgency of the climate issue. You appreciate the urgency and so assume the OP must be advocating an "immediate" extermination.
