Journals not court is place for scientific debate

Journals not court is place for scientific debate - experts

The National Institute of Water and Atmospheric Research (NIWA) faces a legal challenge by climate sceptics group the Climate Science Coalition which is taking the Crown Research Institute to court over the accuracy of its climate data.

In a statement of claim which the coalition says it has filed with the High Court at Auckland, it calls for the New Zealand temperature record collated and maintained by NIWA to be "set aside" and that NIWA be required to produce a "full and accurate" temperature record.

The Science Media Centre sought reaction from New Zealand scientists working in this area of research. Feel free to use these quotes in your stories. Further comments will be added to the Science Media Centre website.

Dr Andy Reisinger, Senior Research Fellow, New Zealand Climate Change Research Institute, VUW comments:

"The High Court action against NIWA by the Climate Science Coalition has a distinctive Kafkaesque feeling to it. NIWA has diligently checked its temperature records, answered innumerable queries about them, and has validated the derived long-term warming trend from a range of different meteorological stations. All these carefully checked temperature records show a clear warming trend. That warming trend in New Zealand is consistent with the increase in global average temperatures, measured by thousands of meteorological stations around the world, including some very remote stations far from any direct human influence, and confirmed further by satellite observations, loss of glaciers, melting ice sheets, reduced frost days, extension of the growing season, increase in heat waves, etc.

"The Climate Science Coalition has not put forward any clear and consistent scientific arguments against this local or global temperature trend, has not published its views in scientific peer-reviewed journals, has not disclosed its own 'scientific' methods by which it claims to show that there has been a cooling rather than warming, and its members have little credibility in the climate science community. But all this seems to be of little relevance: the High Court action will cost taxpayer money to defend the obvious against the obscure and ridiculous, and it will prevent New Zealand's climate scientists from working on the issues that really matter, which is how to improve our understanding of the range of likely further climate changes and allowing New Zealand to take appropriate actions in response.

"One cannot help but think that this may be the real purpose behind this action by the Climate Science Coalition. Taking High Court action will neither advance the science of climate change nor public understanding of the issues at hand, but it will certainly steal productive time away from scientists that could have used that time either on further research or on publicly communicating what we already know about climate change and the reasons behind it.

"I have an extensive network of colleagues across the New Zealand scientific community engaged in climate research. I'm not aware of anybody in this community of active researchers who believes that the NIWA temperature records and warming trend derived from those records are substantially incorrect. Neither am I aware of any credible scientific publications that show otherwise. I'm not aware of any support from the active climate research community for Mr Leyland's claims."

Dr Dave Lowe, consultant LOWENZ Ltd. Renewable Energy and Climate Change Education and former NIWA climate scientist comments:

"To develop a thorough understanding of the science driving climate change takes decades of research and training. New Zealand climate change scientists employed by various Crown Research Institutes and Universities are amongst the best in the world and are internationally respected. Their research is continually scrutinised, peer reviewed and methods validated by independent research organisations world wide and this includes the techniques used to provide New Zealand temperature records.

"The Dominion Post reports that the NZ Climate Science coalition 'wants NIWA to be ordered to produce another accurate record' which does sound rather like ...... I don't like the answer you have provided so please give me another one that I will like. NIWA and other climate scientists in New Zealand are completely over worked and have already produced temperature records which satisfy stringent international peer review, are publicly available and these are apparently the data in dispute by the NZ Climate Science coalition.

"To avoid overworking the scientists further and save tax payers money, my suggestion is that the NZ Climate Science coalition should take the raw data used to produce the NZ temperature records (it is all publicly available) and work with it to produce the answer that they require. However their methods and results should then be subject to the same harsh international peer review and method validation processes as those undergone by the NIWA and other NZ climate scientists."

Ralph Sims, Professor of Sustainable Energy, Director, Centre for Energy Research, Massey University comments:

"Mr Bryan Leyland has considerable experience in energy engineering issues. He has written numerous articles on energy and climate change topics but he is not a climate scientist and I have yet to find a recent paper he has authored or co-authored on any related topic that has appeared in the recent peer-reviewed, scientific literature.

"In contrast many NIWA scientists have PhDs, respected international reputations, published widely in scientific journals, and have gained scientific credibility by their peers.

"The scientific debate on climate science must continue. Techniques, methods and instruments used in the past to measure climate temperature (and a wide range of other climate related changes) need to be continually improved to provide more accurate data and hence give a higher level of understanding of climate change and its possible impacts. This has been, and should always be, the case for any scientific knowledge as it advances and evolves. NIWA scientists are closely involved in this critical national and international debate. Their data has been widely published and is available for everyone to view.

"So I have to wonder who or what is motivating Mr Leyland and the [Climate Science] Coalition to take legal proceedings. If they have a strong scientific argument as Mr Leyland is professing, why not simple submit a paper to a scientific journal in the usual manner and let the debate continue? Or is it that they simply want the publicity in order to keep their organization afloat?"
Euan Mason, Associate Professor, University of Canterbury:

"Peer review and publications in reputable scientific journals that set high standards are the best ways to debate scientific questions. If the court system was capable of the task then we would long since have adopted the legal system as the best way to advance knowledge. This legal suit is a nonsense designed to attract publicity and spread fear, uncertainty and doubt in the absence of a decent argument. The media should ignore it and the judge should throw it out. Let the "Climate Science Coalition" tender its own calculations and subject them to rigorous peer review by submitting a scientific paper."
