The problem is that we are talking too little about actually quantifying this. You make pretty bold statements that sound good, but that contain not much we can use to guide policy decisions. And that matters.
How much will we suffer? For how long? How much will the climate impacts cost, how much adaptation measures, how much will avoidance cost? In terms of money, human lives and living conditions. Who is impacted? We have to put numbers if we want to find an optimum solution.
Because it costs money. It's not just "jobs", it's actual time and effort that we can't spend on other things, which ultimately increases prices and means fewer people can afford things. And while in the West that means maybe cutting back a little, in other regions it can mean a life in poverty and premature death.
