I have often accused the local climate change denial group of shonky science in their treatment of data for their report “Are we feeling warmer yet?“ (see for example New Zealand’s denier-gate). There is the clear issue of their presenting temperature data which had not been corrected for changes in station location, etc. (And of course their unwarranted accusation that our climate scientists were guilty of fraud in using the necessary adjustments). And some of the data they used did not appear to correspond to that on the NIWA database.
Richard Treadgold (the only publicly acknowledged author of the report) consistently refused to clarify any issue I raised with him on the data. He also refused to make his data or methods available. (Although he assured me that his report was backed by his own “science team which wished to remain anonymous”). Read the emails for a summary of his attempts to avoid revealing his data and methods.
However, Treadgold seems to have inadvertently let some of his data slip by providing a link to a spreadsheet (Summary AWFWY RTreadgold.xls which is in a directory for his blog). This provides an opportunity to check in detail the level of scientific competence in this group.
