New Zealand climate scientists embroil themselves in as much of a climate data fraud scandal as Climategate and with eerily similar methods and results.
The New Zealand Climate Science Coalition (NZCSC) in its article ‘NIWA Challenged to Show Why and How Temperature Records Were Adjusted’ (February 7, 2010) provides its readers with an insight into the climate scandal dubbed 'Kiwigate.'
NIWA is New Zealand’s National Institute of Water and Atmospheric Research and is accused of repeatedly frustrating NZCSC in its attempts to get government climatologists to explain how they managed to create a warming trend for their nation’s climate that is not borne out by the actual temperature record.
According to NZCSC, climate boffins cooked the books by using the same alleged ‘trick’ employed by British and American doomsaying scientists. This involves subtly imposing a warming bias during what is known as the ‘homogenisation’ process that occurs when climate data needs to be adjusted.
When such data adjustments (homogenisations) are made, scientists must keep their working calculations so that other scientists can test the reasonableness of those adjustments. According to an article in Mathematical Geosciences (April 2009) homogenisation of climate data needs to be done because “non-climatic factors make data unrepresentative of the actual climate variation.”
The article tells us that if the raw data is not homogenised (or, in this case, “fudged” according to sceptics) the “conclusions of climatic and hydrological studies are potentially biased.”
