All else equal, an increase in CO2 will just automatically make for an increase in temperature.

A look at a little longer period of earth's history sort of breaks down any simplistic assumptions
about a correlation between CO2 levels and temperature.

Late Carboniferous to Early Permian time (315 mya -- 270 mya) is the only time period in the last 600 million
years when both atmospheric CO2 and temperatures were as low as they are today (Quaternary Period ).

GREAT for posting that chart.

All we have to do now is move continents to offset the CO₂.
