First, definitions have tended to be confused due to the fact that equilibrium climate sensitivity measures (Charney) used to project warming for this century by the IPCC only take into account about half of long-term (slow feedback) warming should CO2 and other greenhouse gas levels remain high.

For example, equilibrium climate sensitivity measures show an effective rate of warming by about 3 degrees Celsius (C) for every doubling of CO2 from 1880 onward. By this…
