I would like to see more discussion about what we do in the scenario where we simply can't get it together - politically, individually, economically - to drastically slash emissions worldwide. Is carbon capture a reasonable hope? What we can do to increase our odds that we figure that out before we start suffering real population collapse? How much of an idea do we actually have of what a 3- or 4-degree warmer world will look like? How much do we think we can predict and how much falls under "this is a huge chaotic system and we can't know"?

In the developed world we probably have the technology to deal with it, but it’s going to require a lot of adaptation and it’s not clear out society has the capacity for the rate of adaptations.

Large scale carbon capture is actually the only way forward. It's already way too late for just reducing emissions. The required negative emissions are just getting more expensive with each day, but it's still possible.

  how is something that doesn't exist yet the only way forward compared to just use less energy, consume less etc. there's a way, it's just not comfortable

    In this scenario energy would be stratified by wealth and geography and result in massive civil unrest. So it’s absolutely possible, just highly unlikely to happen until it’s absolutely necessary, and likely too late to actually “solve” the problem. So from a societal function perspective, carbon capture is the the only way

How many Gt of carbon are we capturing annually? According to Wikipedia, less than 50Mt. We need to scale up hundreds of times to make a sizable dent in global emissions.
