Idso (1998)[29] calculated based on eight natural experiments a ? of 0.1 °C/(Wm?2) resulting in a climate sensitivity of only 0.4 °C for a doubling of the concentration of CO2 in the atmosphere Does this imply that ?  of  1 °C/(Wm?2)   results in a climate sensitivity of  4 C climate sensitivity is usually used in the context … Continue reading CLIMATE SENSITIVITY
