Author addresses key issues and drawbacks of the infamous Stern Review (2006). It's quite a read and does provide a nice example of how everything, every single paper, books, newsitem, ..., should be put under close scrutiny and checked for consistency and truth. (Which, with the lack of time of a single individual, can be nigh impossible.)
Below, an excerpt. Still below, the source.
"The surprises are potential scenarios which scientists can outline to the best of their ability and
which involve loss of life and human infrastructure on a grand scale; losses only precedented by the mass movement of people, death and destruction of World War II.
However, there is no enemy to defeat nor peace treaty to sign, only our own actions to control. Once the surprises start in earnest action will be too little too late. For example, ice sheet melt causing a six meter sea level rise is a scenario which would flood all the major coastal cities. A two-meter sea level rise alone will displace hundreds of millions of people and inundate low lying cities (Lenton et al., 2006: 15).
How does this get transformed into X% GDP with any semblance of meaning left in the utter disaster and human suffering which would be entailed? Indeed, there are four major problems with the whole framing of human induced climate change as GDP losses and gains."
