New Zealand Climate Scientist Chris de Freitas revealed on May 1, 2009 that “warming and CO2 are not well correlated.” de Freitas added, “the effect of CO2 on global temperature is already close to its maximum. Adding more has an ever decreasing effect.”
Climate Scientist Dr. Chris de Freitas: ‘Current warm phase…is not unprecedented’ — ‘From the results of research to date, it appears the influence of increasing CO2 on global warming is almost indiscernible. Future warming could occur, but there is no evidence to suggest it will amount to much’ - 'Whatever the cause of the current warm phase, its occurrence is not unprecedented. Global warming happened from 1850 to 1940, then cooling to 1979. During the Medieval Warm Period from 900 to 1200AD, the Vikings sailed in arctic waters that are now covered with sea ice, and farmed Greenland soil that is now too cold for agriculture'
New Zealand Scientist Chris de Freitas: ‘Argument from authority has no place in science’ - 'Temperature trends detected are small, usually just a few tenths of one degree Celsius over 100 years, a rate that is exceeded by the data's standard error. Statistically this means the trend is indistinguishable from zero'
De Freitas was part of original 1000 dissenting scientists: Climate scientist Dr. Chris de Freitas of the University of Auckland, N.Z., also converted from a believer in man-made global warming to a skeptic. "At first I accepted that increases in human-caused additions of carbon dioxide and methane in the atmosphere would trigger changes in water vapor, etc. and lead to dangerous ‘global warming,' but with time and with the results of research, I formed the view that, although it makes for a good story, it is unlikely that the man-made changes are drivers of significant climate variation," de Freitas wrote on August 17, 2006. "I accept there may be small changes. But I see the risk of anything serious to be minute," he added. "One could reasonably argue that lack of evidence is not a good reason for complacency. But I believe the billions of dollars committed to GW research and lobbying for GW and for Kyoto treaties etc could be better spent on uncontroversial and very real environmental problems (such as air pollution, poor sanitation, provision of clean water and improved health services) that we know affect tens of millions of people," de Freitas concluded. De Freitas was one of the 60 scientists who wrote an April 6, 2006 letter urging withdrawal of Kyoto to Canadian Prime Minister Stephen Harper which stated in part, "Significant [scientific] advances have been made since the [Kyoto] protocol was created, many of which are taking us away from a concern about increasing greenhouse gases."

Prominent New Zealand scientist Associate Professor Chris de Freitas has died after a two-year struggle with cancer.
Born in 1948, the Trindad-born scientist held many major roles at the University of Auckland, including Deputy Dean of Science and four years as Pro Vice-Chancellor.
He also formerly served as vice-president of the Meteorological Society of New Zealand, vice-president of the International Society of Biometeorology, co-founder of the Australia New Zealand Climate Forum and editor of the international journal Climate Research.
The recently-retired environment researcher and lecturer was well known for his sceptical views on anthropogenic climate change – frequently arguing that the potential impacts of warming had been misunderstood, misinterpreted and distorted – which often made him a controversial and criticised figure within the science community.
He was credited with more than 200 publications in the areas of applied climatology, bioclimatology, meteorology, environmental change, microclimatology and general review commentaries, including two recent books, New Environmentalism: Managing New Zealand’s Environmental Diversity, and Natural Hazards in Australasia.
De Freitas was three times the recipient of the New Zealand Association of Scientists’ Science Communicator Award and wrote many pieces for the Herald, the most recent of which was published in January, calling the state of the country’s rivers and lakes an “environmental crisis second to none”.
“It is an uncontroversial fact that the state of the country’s freshwater resources has for decades been moving towards ecological collapse,” he said, calling for better policy and better information.
His students appreciated him for an enthusiastic lecturing style, his high expectations that they should think critically and design their investigations well, and he was known to be generous in support of their research endeavours.
His research and writing continue to have an impact in the fields of climatology, bioclimatology and environmental change through the many journal publications and books he wrote during over his long career.
He is survived by wife Nancy and sons Colin and Andrew.
