We certainly do have a known solution to emissions, it’s to cut them. The most straightforward way to do that is to cut consumption, drop standards of living.

The solution is crystal clear, we have real life working examples right now all over the world, for example the people living in Bangladesh are at a level of consumption that would actually be sustainable for all 8 billion of us to embrace.

The solution is clear, it’s just that we don’t like it, so we readily embrace the magical thinking that we can have our cake and eat it too.

Cutting consumption isn't the only way to reduce emissions. The other way is to change the type of energy fueling the consumption with clean energy. It seems to me like it would be a lot easier to build a bunch nuclear reactors than it would be to convince billions of people to significantly reduce their standard of living.

We have in fact several known working solutions. You don’t have to implement a solution to know that it works. The problem is that they cost money to implement and nobody wants to pay.
