I think you're confusing policy & politics. Start with policy. Ignoring the human-cull-with-nukes snark, there is no population policy that is relevant to the timescale at which climate breakdown needs to be tackled. Population policy falls at the first hurdle so you never get to the politics. There are plenty of policies that could stem the rise in global emissions, so we move on to the politics. There I agree with you. There isn't a plausible political route to the global policies we need. My view of the future is that ecosystems will collapse, and, probably in the second half of this century, 'civilisation' (huh) will crumble as mutiple successive wars over declining resources and forced population movements sweep the globe.
