Can you clarify what TSC means exactly there? in equation 3 it enters a consumption equation in multiplicative form yet in the appendix ""TSC" is the equilibrium response of global mean temperature to a doublin of atmospheric CO2 concentrations (°C)". Isn't that a confusion of units to multiply a financial quantity by a coefficient that determines temperature? As such I'm unable to tell (with the time I have available here!) how Nordhaus estimates the severity of any given global temperature change i.e. what data is used to calibrate that relationship And more crucially to tell whether we're measuring the right thing, as all this seems to be measured in terms of consumption which is usually a financial measure: if (repeating my point above) food takes substantially more effort to produce, or is scarce, in a different climate, then consumption could be shown to increase even though people's wellbeing would decrease?
