I am engaged in discussion with a modestly prominent climate skeptic who argues that global warming isn't a problem because as CO2 concentrations rise climate sensitivity reduces. I recall coming across this notion before but I don't know how much peer-reviewed work has been done on it. I'd appreciate some help with references to peer- reviewed papers that address the idea that climate sensitivity may be logarithmic rather than linear so that as atmospheric CO2 concentrations rise the effective climate sensitivity reduces and discuss the likely levels at which this reduction becomes significant in terms of reducing the GWP of CO2.
