No problem with this, apart from convincing like 5-6 billion people to cut their standards of living to half. Also less people is needed, few children. Sounds like impossible now without concentrated media effort and all ruling parties probably would lose for decades.

If all human carbon emissions magically ceased today anthropomorphic global warming and its concomitant environmental changes will still continue to unfold for the next few centuries or millennia, at a minimum, before settling into a new (albeit shifted) "natural" evolution. It will take millions of years for the human carbon emissions to be cycled back into the lithosphere.

In this sense, continued emissions only accelerate and compound the current process unfolding. Global warming as it exists today cannot be stopped passively.

That was the previous poster's point. We can infer that their unstated objective is the end of global warming in the near future (i.e. in the next few centuries), the achievement of which necessarily requires active intervention.

I might infer that your unstated objective is not the end of global warming, but the end of ongoing human interference per se. That's an entirely different objective, albeit no less legitimate.

If I'm correct (and I'm confident in my assessment wrt to the previous poster), then you two are talking past each other.
