I think a PP without qualification becomes so nebulous that it can't be used in anger. Like what is wrong with saying that the most precautious we can be is to turn off all fossil fuels immediately? Lets stop cement and fertilizer production while we're at it. Starvation concerns? Irrelevant because we're being Precautious(TM). When are 2/3 going to be in dire straits? 10 years, 50 years, 100 years? It matters to our policy response, that is my whole point. Repeating "global warming bad" isn't wrong but it doesn't inform policy. More jobs = better?! That simply means it takes more resources to produce the same output. That is efficiency going down and is not good for the economy. But that doesn't matter because using the PP means that economic health isn't important. THIS is why it is important that institutions like IPCC need to consider all possibilities. We can't tell if using more labour is a good thing unless we can compare it to the downside! If we limit our imagination to 1.5C warming, we are deluding ourselves.
