^ The global CO2 emissions over the past 2000 years.
^ The global temperature over the past 2000 years.
^ Super-imposed and adjusted in X-axis to fit (correct in Y-axis). Correction based on peaks and valleys of the temperature graph pre 1750 matching the peaks and valleys' "height" on the CO2 graph.
Would suggest we have at least 5.5 degrees C of warming already 'built in', possibly as much as 7 degrees. Enough to wipe us out either way......

We haven't seen this high CO2 for at least the past 800K years (yeah it's an old vid): https://www.youtube.com/watch?v=UatUDnFmNTY

Looks like you need to go waaaaay back to get equal CO2 concentrations. And each year, around May, that 'way back year' changes, lol.
