Estimating the errors inherent in the kind of measurements used by Maciejewski and his co-authors is a tough thing to do, Bean says; if the actual errors in the data were larger than the researchers had accounted for, the variations in the observed transit times could vanish.

The data is only 33 years in length, but based on that data, there is no first order correlation between temperature and CO2 during its 33 year period and this suggests that then signal to CO2 (ie., Climate Sensitivity) is so low that it can not be measured within the sensitivity, resolution and errors of our best current temperature measurements.

While there remain disparities among different tropospheric temperature trends estimated from satellite Microwave Sounding Unit (MSU and advanced MSU) measurements since 1979, and all likely still contain residual errors, estimates have been substantially improved (and data set differences reduced) through adjustments for issues of changing satellites, orbit decay and drift in local crossing time (i.e., diurnal cycle effects).
