I wonder why the chart for CO2 concentration starts at 1960 vs 1850 for the global mean temperature difference

  Without knowing, my guess would be that's when we started measuring & recording those things?

    That is the right answer.

  The Mauna Loa daily CO2 measurements started in 1958. Before that, there weren't any continuous measurements happening.
