UN IPCC Scientist: ‘No convincing scientific arguments to support claim that increases in greenhouse gases are harmful to the climate’

Selected excerpts from UN IPCC scientist’s recent testimony.

IPCC reviewer and climate researcher and chemist Dr. Vincent Gray of New Zealand is an expert reviewer on every single draft of the IPCC reports going back to 1990 and author of The Greenhouse Delusion: A Critique of “Climate Change 2001. Dr. Gray’s research is featured on page 155 of the 2009 edition of the 255-page “U.S. Senate Minority Report Update: More Than 700 International Scientists Dissent Over Man-Made Global Warming Claims”

Below are selected excerpts of his testimony before New Zealand’s Committee for the Emissions Trading Scheme Review May 5, 2009:

I am an experienced research chemist, with a PhD from Cambridge 1946, and a long research career in the UK, France, Canada, New Zealand and China. I have over 100 scientific publications, many of them on climate science, which I have studied intensively for the past 18 years.

I have been an Expert Reviewer for the IPCC Reports since the beginning in 1990.I submitted 1,898 comments to the last (fourth) Working Group I (Science) Report.

I was recently invited to the Beijing Climate Center as a Visiting Scholar and I recently lectured to a Conference in New York.

I have reluctantly concluded, after detailed study of the evidence presented by the IPCC, that there are no convincing scientific arguments to support the claim that increases in greenhouse gases are harmful to the climate. […]

The IPCC “central/benchmark projections” are based on a combination pf ridiculously oversimplified models and unrealistic futures scenarios. The projections themselves conflict with the current fall in global temperatures, the absence of any warming in New Zealand, and the lack of local evidence of sea level change. […]

The presumed dangers of failing to implement the Emissions Trading Scheme appear to be illusory. We have enough problems coping with the current economic crisis without burdening ourselves with additional costs to our manufacturing and farming industries and adopting uneconomic sources of energy. […]

Changes in climate can have many causes, some of which are partially understood, but the influence of increases in greenhouse gases are not likely to be important if there is no detectable warming resulting from them. […] In reality the sun only shines in the daytime. The earth absorbs energy by day and emits it by night. It rotates, so that all surfaces have a diurnal and seasonal cycle. There is no energy balance anywhere, …
