Krw didn't read the link he posted - or didn't understand it if he did read it.
Historically, CO2 levels lag temperature rises because the flip from a glac ial to an inter-glacial is driven by subtle changes in where the sun shine brightest at particular parts of the year - Milankovich effect.
That provides the - small - initial warming, that drives CO2 out of a sligh tly warming ocean to produce extra heating by the greenhouse effect. By bur ning fossil carbon and injecting the extra CO2 into the atmosphere, we get the warming directly, rather than as a positive feedback.
In fact half the CO2 we inject into the atmosphere ends up dissolving in th e oceans - warmer oceans can dissolve less CO2 but we haven't warming them enough yet for the reduced solubility to trump the increases partial press ure of CO2 int the atmosphere.
Something else that krw didn't actually understand, but didn't bother to sn ip.
