CBS Declan McCullagh ClimateGate story

http://pajamasmedia.com/instapundit/88955/

One programmer highlighted the error of relying on computer code that, if it generates an error message, continues as if nothing untoward ever occurred. Another debugged the code by pointing out why the output of a calculation that should always generate a positive number was incorrectly generating a negative one. A third concluded: “I feel for this guy. He’s obviously spent years trying to get data from undocumented and completely messy sources.”

Programmer-written comments inserted into CRU’s Fortran code have drawn fire as well. The file briffa_sep98_d.pro says: “Apply a VERY ARTIFICAL correction for decline!!” and “APPLY ARTIFICIAL CORRECTION.” Another, quantify_tsdcal.pro, says: “Low pass filtering at century and longer time scales never gets rid of the trend – so eventually I start to scale down the 120-yr low pass time series to mimic the effect of removing/adding longer time scales!”
