| Veteran Wellington climate consultant, Dr Vincent Gray, expert reviewer of all four IPCC Assessment Reports, explains why he has resigned his longtime membership of the Royal Society of New Zealand in protest at the inaccuracies in a report on climate change issued on 12 July by the Society's Climate Committee.
COMMENTS ON THE RECENT STATEMENT BY THE CLIMATE COMMITTEE OF THE ROYAL SOCIETY OF NEW ZEALAND
Dr Vincent Gray
INTRODUCTION
As an Expert Reviewer for the Intergovernmental Panel on Climate Change for eighteen years, that is to say, from the very beginning. I have submitted thousands of comments to all of the Reports. My comments on the Fourth IPCC Report, all 1,898 of them, are to be found at IPCC (2007) and my opinions of the IPCC are in Gray (2008b)
I am therefore very familiar with the arguments presented by the IPCC, many of which have now been copied by the Royal Society of New Zealand, and the responses to them.
I will first comment on the Introduction
to make absolutely clear what the evidence is for climate change and anthropogenic (human-induced) causes.
The climate has always changed and always will. No evidence whatsoever for a human contribution to the climate is given in their following statement.
Their Summary is as follows:
The globe is warming
This statement is a lie. The globe is currently cooling. According to the CSSP Report (Karl et al 2007), there are currently nine authorities currently involved in providing a dataset of monthly global temperature anomalies. They are
NOAA’s National Climate Data Center (NCDC, GHCN-COADS)
NASA’s Goddard Institute for Space Studies (GISS)
Climatic Research Unit of the University of East Anglia (HadCRUT2v)
NOAA radiosonde network , (RATPAC)
Hadley Centre Radiosonde Network (HadAT2)
University of Alabama Lower Troposphere TLT MSU (UAH )
Remote Sensing Systems Lower Troposphere TLT MSU (RSS)
National Center for Environmental Protection Reanalysis (NCEP50)
European Centre for Medium Range Weather Forecasts Reanalysis (ERA40)
Eight of these authorities agree that the globe is currently cooling. Only GISS disagrees.
because of increasing greenhouse gas emissions
No evidence is presented to justify this conclusion. There are “projections” of computer models but these are not predictions, they are merely the results of assumptions made in the model. No “projected” result has ever been successfully related to an actual change in the climate.
Measurements show that greenhouse gas concentrations in the atmosphere
are well above levels seen for many thousands of years.
This statement is a lie. 90,000 measurements published in peer-reviewed journals since 1850, some by Nobel Prize-winners, have been suppressed by the IPCC because they do not agree with this statement. (Beck 2007). Stability of carbon dioxide in ice cores thousands of years old is questionable. (Jaworowski 2007). Recent measurements of carbon dioxide are confined only to exceptional circumstances over the ocean, and do not include measurements over land. (Manning et al 1994). |
