The Right CO2 Reduction Target for a Soft Landing?

<<DRAFT; 081011>>. Much confusion and fuzzy-headed thinking surrounds the topic of climate change CO2 reduction targets. A lot of it is generated by the IPCC modeling scenarios relating CO2 concentrations in parts per million (ppm) to average surface temperature increases, and the IPCC recomendation of the 2 degree increase (celius) target and its associated CO2 concentration of 450 ppm.
Unfortunately, that scneario, according to the IPCC's own modeling has only a 50 percent chance of being acheived,
