That certainly seems to be what most people are doing even if they are saying something different.
No, I don't think so. We have a pretty good idea of what kind of things are going to happen - if we were serious about trying to withstand them we'd be putting more efforts into flood defences, desalination plants, disaster-relief type stuff - and on a longer-term level maybe food-supply work. Even if you believe what's needed is industry, in the long-term the scientific uses of oil and plastics are far more vital than burning it moving people between the office and the suburbs. But no-one really believes at a visceral level that the oil supply is limited, because we've spent our whole lives living with abundant oil. Add in a dose of classic tragedy of the commons - reducing carbon emissions makes things better for everyone, while building up your own economy/industry and ignoring emissions hurts the common cause but is profitable for individual nations.
And then you said: "if we were serious about trying to withstand them we'd be putting more efforts into flood defences, desalination plants, disaster-relief"
These are the same.
That's what I took from it too. Grab everything we can and dig in.
