By courtesy of Mr Warwick Hughes, who kindly sent it to us, we are pleased to post this spreadsheet containing the historical New Zealand temperature series. The data are from the seven weather stations chosen by Dr Salinger and adjusted by him to represent the country’s temperatures, although it does not include the actual adjustments made or the reasons for them.
When plotted, it produces a graph similar to the one on NIWA’s web site that shows strong warming during the 20th century.
