It will happen, we all know it, and people are most certainly thinking about it. But it shouldn't be opposed to reducing CO2. Even if it is already happening, reducing CO2 will (most likely) also reduce the warming itself, and make the future slightly more bearable.

Moreover, global warming is just the tip of the iceberg, it's the thing that is presented to us in the most direct ways, but other things like mass extinctions of species, oil depravity, overpopulation, forever chemicals etc. Etc. Will be a problem someday also.

So instead of trying to "cope" with every catastrophy that is thrown at us (while making living on earth more and more annoying), maybe we should think about the solutions on a global scale, because there's no way it will happen without that

So there's really nothing one can do. Even living the regular lifestyle of any western country is by itself a contribution to the issue. Stop fooling yourself with technical solutions, as it will only push the issue for later, or be counter productive

Changes can't come without a massive overhaul of our economy and society (probably for the worse)
