Until cloud and precipitation data are adequate AND accounted for properly AND the error bands are low enough to cover 1/10 degree increments, we can’t say there is ANY effect from CO2 on temperature. It is at most a conjecture, and not a very good one. You can not ignore the major driver of changes of temperatures (as shown in the above graph) and then attribute temperature changes to something else by supposition.
