Wow! The scandal just gets juicier and juicier. Now it seems that the Kiwis may have been at it too – tinkering with raw data to make “Global Warming” look scarier than it really is. (Hat tip: Watts Up With That ; Ian Wishart )
The alleged villains this time are the climate scientists at the National Institute of Water and Atmospheric Research (NiWA) – New Zealand’s answer to Britain’s Climate Research Unit. And to judge by this news alert by the Climate Science Coalition of NZ, both institutions share a similarly laissez-faire attitude to scientific accuracy.
Compare and contrast these two graphs and you’ll see .
This is the graph from NiWA’s website, showing mean annual temperature over New Zealand from 1853. Note the dotted straight line showing the upward trend. Worrying, isn’t it? Almost enough to make you fall in love your flickery, yellowy new eco-light bulbs, recycle your kids and commit yourself to a binding agreement at Copenhagen.
Now have a look at this analysis of the raw data taken from exactly the same temperature stations.
Can you see the difference? I can – and I know as little about science as Al Gore.
