Leading Climate Scientists Welcome Judge’s Decision on Temperatures
A group of leading New Zealand climate scientists (listed below) welcomed Justice Geoffrey Venning’s ruling to throw out
the claim by the New Zealand Climate Science Education Trust (CSET, a small group of climate change “sceptics”) that
NIWA had acted fraudulently in putting together its ‘7-station’ temperature series.
Spokesperson for the group, Associate Professor James Renwick of Victoria University said he was pleased that the court
had respected and reaffirmed the credibility of the scientific process. It was a strong message to those wanting to
challenge widely-agreed scientific findings to do so honestly and openly in scientific forums.
Dr Renwick went on to say “Scientific analysis and discussion is carried out through the peer-reviewed literature. The
basic science of climate change (global warming) has been established for well over a century, and almost all scientists
active in climate research agree that human activity is causing the climate to change. For a small group of scientists
to appeal to a court of law to find otherwise is bizarre.”
New Zealand temperatures have warmed by about 1°C in the last 100 years, associated with loss of glacier ice in the
Southern Alps, reduced frost occurrence, and other changes. Globally, evidence of climate change includes sea-level
rise, melting glaciers, and rapidly diminishing arctic sea ice.
The court case has helped raise the profile of the claimants. Much more importantly, the case represents a massive waste
of New Zealand tax payer’s funds. In defending the claim, NIWA has spent a huge amount (estimated at well over $100,000)
and has diverted a number of its scientists away from their research. The country can ill afford to waste such an
amount. “This misguided action of a small group adds confusion to a simple issue – the world is warming and future
generations of New Zealanders will have to deal with the consequences” Dr Renwick said.
