See that's the problem. Limiting temp change is not a goal distinct from saving millions of lives and trillions of dollars, it's literally about saving millions of lives and trillions of dollars (as well as saving other things more difficult to put price on). And that's the problem with abstractly talking about degrees of warming – we should be directly modelling the human and economic costs of every 0.1° of additional warming. Some economists are doing just that, of course, but then again nobody really knows how reliable any of the models are, so they're easy to ignore.
