NIWA Unable To Justify Official Temperature Record

"The [New Zealand] National Institute of Water and Atmospheric Research (NIWA) has been urged by the New Zealand Climate Science Coalition (NZCSC) to abandon all of its in-house adjustments to temperature records. This follows an admission by NIWA that it no longer holds the records that would support its in-house manipulation of official temperature readings....[Quoting Terry Dunleavy, secretary of NZCSC:] 'NIWA has forfeited confidence in the credibility of its temperature recording procedures....What is needed is open access in the public domain to all of the known reasons for post-reading adjustments to enable independent climate analysts to make their own comparative assessments of temperature variations throughout New Zealand since the middle of the 19th century.'"
