Comment on 'Unresolved issues with the assessment of multidecadal global land surface temperature trends' by Roger A. Pielke Sr. et al.

摘要

We note Pielke et al. 's [2007] many concerns with the historical global mean land surface air temperature record, which range from the inclusion of nocturnal temperature observations to the importance of factoring in humidity. We will, however, limit our comments to two of Pielke et al.'s [2007] eight aspects where our additional analyses have shed considerable light.
