Assume that the linearized analysis of climate leading to (34.46)

is correct, and F_2× ≅ 3.7 W/m². Assume also that climate models correctly predict that quadrupling of CO₂ levels would give a temperature shift ofΔT₄× ≅ 6.4 ^◦C. Use a quadratic function to fit the change in temperature as a function of the logarithm of the multiplicative increase μ in atmospheric CO₂ levels to estimate the change in temperature with a doubling of pre-industrial carbon dioxide levels.
