In a horrifying echo of CRU's loss of its temperature data, climatologists in New Zealand seem to have lost the calculations they use to adjust their temperature data.
The 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.
The killer point here is that the raw data has no trend, while the adjusted data shows warming. Funny that.
