Humanity's bull-in-a-china-shop approach to climate has to stop. Regardless of future growth, we are already in overshoot in terms of climate impact. We need to take responsibility for stabilizing the climate. Once we've done that, we will have the tools enabling us to search for an optimal climate equilibrium. That should be interesting, politically...

But before we can get to that, we need to correct the overshoot urgently. This requires optimizing resource use to produce, at minimum, the same amount of food etc. with fewer primary resources, and producing much less greenhouse gases. If we don't manage this, we are heading for die-off (which is one of Nature's wonderful ways of balancing the population/resource budgets).

Now comes the question of growth. The study of demographic transition shows us that populations stop growing once a certain level of education and well-being is achieved. World population is levelling off, or at least is no longer in exponential growth, because of this phenomenon. The urgent goal is to help the countries who aren't there yet, rather than decreeing some arbitrary limit to population (and enforcing it how?)
