“The open admission by a climate scientist of the New Zealand National Institute of Water and Atmospheric Research (NIWA), Dr Jim Renwick, that his organisation achieves only 50 per cent accuracy in its climate forecasts, and that this is as good as any other forecaster around the world, should be a wake-up call for world political leaders,” said Rear Admiral Jack Welch, chairman of the New Zealand Climate Science Coalition.

Dr. Jim Renwick, a lead author of the IPCC 4th Assessment Report, admitted to the New Zealand Herald in June 2007, “Half of the variability in the climate system is not predictable, so we don’t expect to do terrifically well.”

Does anyone smell a smoking gun?
