So the alternative is human survival and success...
Our most effective weapon is our minds. We only use it to the greatest effect when we are threatened with destruction. As weather events kill more and more people we will begin to see the threat for what it is and start spending the time and money needed to address the issue. All we are left with is geo-engineering so we will develop processes to remove CO2 from the air and sequester it underground. It will be based on natural processes. The end product (algea based slime) will be very similar to oil and will be injected into abandoned wells in Texas under supervision of the ROCKMAN. The existing wind farms will be used to power the process.
In the meantime small mirrors will be seeded into the arctic vortex to cool the local area and allow the ice cap to reform bringing the weather back into BAU. So Planty can safely go fishing.
Of course these processes will take at least 50 years to make a difference so the end population of 1 billion will have a much better chance of survival. Colonies on Mars will have to wait for the next technical revolution when we find a truly sustainable energy source. Unfortunately KJ passed on when the interplanetary shuttle suffocated on methane farts.
After another 1000 years the next Ice age will be unavoidable and we will dig all that shit up and burn it all over again
