Indeed this is not an engineering problem. The most frustrating part of this all is that we are still mostly only talking about climate change, when our ecological disaster is that we have simultaneously crossed or are soon crossing most planetary boundaries (https://en.m.wikipedia.org/wiki/Planetary_boundaries https://en.m.wikipedia.org/wiki/Planetary_boundaries) at the same time. Looking at only CO2 levels makes the solution seem technical: just start using better tech. Or worse: placing hope on geoengineering which is only about alleviating one boundary at the expense of most of the others. But if you look at the facts that we have been for many decades exploiting nature faster than nature can regenerate, and that all economic growth has come hand in hand with more environmental stress, the root problem and the only solution becomes pretty obvious: heavy global tax to all nature exploitation and after that inevitably halts most economic growth, a redistribution of wealth and social restructuring. We have no hope to have a livable planet the next century unless us westerners learn to not want more stuff, but learn to live with much, much less.
