(a) natural variation in the Earth's climate is far larger than anything we can manage anthropogenically anyway so attempts to cut carbon emissions are a waste of time, or
(b) We're only being saved from CO2-induced global warming by a mini ice-age, therefore it's even more urgent to cut CO2 emissions because temperatures are just gonna shoot up as soon as the ice age ends.
Taking a contrary view: there are too many of us already. A smaller population will be more sustainable in the long term.
Unless you want unlimited growth with a huge apocalyptic human extinction event at the end.
In other words, I don't care specifically about industrial age humans. I want post-industrial and post-post-post-industrial age humans to survive too.
