All data shows that the most significant increase in global CO2 and

Of course it's not a coincidence -- because it's not true.

There are NO reliable records of GLOBAL temperatures prior to the late 19th
century, for three reasons: first, early thermometers were not accurate enough
to allow valid comparisons with modern data; second, record-keeping was spotty
and inconsistent; and third, temperature measurements were neither made nor
recorded *globally*.


Who said anything about thermometers? Calibrate tree rings against
modern thermometers and you can go back millennia. Ditto for oxygen
isotopes in marine snail shells.
