Actually, CO2 concentrations started rising in the mid-19th Century, and a significant amount of the 1850-1940 warming is also thought to be CO2-related, although that's not as well established as the post-1950 warming.
Some bounce-back from the LIA was natural, but we've far exceeded that, and even more telling is the acceleration from warming of .06C per decade in the 20th Century to over twice that currently.
