I'm interested in following this, if others are game - CO2 has risen in a straight line (more or less) during measured periods (which is only since WW2 by instrumentation, estimates and proxies before that) but temps haven't - there is the "escalator" theory (favoured by Skeptical Science) and the "hidden heat in the seas" theory (for which evidence is slight to none at all).
