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



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


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


That is the right answer.
