The passage around this formula
The third layer is the direct check on the whole chain: does measured forcing show up as a measured energy imbalance at the top of the atmosphere and inside the climate system? This is where the ocean enters as an instrument rather than a passive backdrop, addressed below. is the standard simplified radiative-forcing relation for CO2, where is a reference concentration, C the current concentration, and an empirically constrained coefficient (commonly near 5.35 W m⁻² in widely used formulations). Its logarithmic form is itself an empirical and physical result: it reflects the fact that CO2’s absorption bands are already partially saturated at pre-industrial concentrations, so each…

Addition combines quantities; subtraction measures the signed difference between them. Parentheses show what is combined before the rest of the expression is evaluated.
