These solutions are touching only the technical aspects and I believe most experts probably know exactly what to do, but that doesn't mean they can actually do it simply because its execution depends largely on politics. We can have one country practicing it but another just doing the complete opposite to ruin it for everyone, then realistically we don't really make any progress at all no matter how much effort we put in. For any climate change solutions to really become effective, it will definitely require a joined global effort. That's where our root problem is, until we can solve that the rest are just useless noises.
