Graph shows an uncanny correlation between CO2 level and temperature

Just ran across this gem: It graphs CO2 levels, measured from air bubbles in Antarctic ice cores, against local mean temperature, as determined from those same ice cores, for the last 450,000 years.

Note the amazing correlation, citizen!  How remarkably temperature change follows changing CO2 levels!  It's uncanny, eh?  Of course mere correlation doesn't prove causation, but it's absolutely clear that temperature follows CO2 levels!  Doesn't take a PhD to see that, eh citizen? 

Just kidding!  The graph shows no such thing--no correlation at all between the two.  But I'm sure AOC will be along any minute with a totally persuasive explanation debunking the four papers that produced this graph.  And of course all Democrats nod thoughtfully at whatever AOC says, cuz her degree in atmospheric physics makes it hard to disagree with her, eh?
