The equilibrium climate sensitivity (ECS) is a convenient yardstick to measure how sensitively the climate system responds to perturbations in the atmospheric concentration of greenhouse gases such as CO2.

For some, a few hundred ppm of atmospheric CO2 may seem like small potatoes — how could that possible affect the temperature of the very massive climate system?

That allows us to extrapolate theories as to how it MIGHT change the atmospheric system as a whole.

I will now analyse how the system could work and show that composition changes not involving changes in mass only affect atmospheric volume and circulation patterns and not surface temperature.

BBD - With all due respect, the study does nothing to explain how the scientific community has failed to come to grips with the fact that there is now pretty good evidence that we do not understand how the climate system works well enough to accurately determine the impact of additional atmospheric CO2.

there is now pretty good evidence that we do not understand how the climate system works well enough to accurately determine the impact of additional atmospheric CO2.

Further, trying to reduce the complexity of the atmospheric system to a verbal discussion is rather like learning how to ride a bicycle from a book.

Do you agree that a nation that refuses to reduce its ghg emission to its fair share of safe global ghg emissions on the basis of cost to it is implicitly taking a position on how high atmospheric concentrations of ghgs should be allowed to rise and that the higher atmosphere ghg concentrations rise the more people and the ecological systems on which life depends will be harmed?.

Counters: «Once the model finishes producing the data representing how radiative forcing has changed over time, we can then go back and analyze that data to see how the climate system in terms of temperature and other factors will change based on empirical relationships between atmospheric factors and changes in temperature.»
