Jack Barrett

 Credentials

• Ph.D. in Physical chemistry from Manchester. [1]

 Background

Barrett is a former chemistry researcher at King’s College in London.

According to Barrett Bellamy Climate, his interest in climate change developed with the 1992 Report of the Intergovernmental Panel on Climate Change [IPCC]. "He became sceptical about climate modelling and what seemed to him the exaggerated claims emerging from the computer programmes about our future global climate." [5]

Stance on Climate Change

According to a summary of Jack Barrett's article in New Scientist,

1 CO2 levels have risen from 280 to 350 parts per million in the last 100 years

2 Jack Barrett of Imperial College London suggests that the burning of all fossil fuels would result in a four fold increase in CO2 levels to 1400 parts per million.

3 Jack Barrett also suggests that the lowest 30 metres of the troposphere already contains all the CO2 necessary to absorb all the radiation reflected and emitted back by the earth's surface at most infra-red wavelengths, except for the "window" between 7.5 and 14 micrometres, through which radiation escapes back into space.

4 Finally, JB suggests that the most likely consequence of all of this is flourishing vegetation rather than runaway global warming. [2]

Barrett and the "Leipzig Declaration"

Barrett was one of the signatories to the "Leipzig Declaration," and according to SourceWatch, was also a keynote speaker at the Leipzig Declaration launch. [3]

Barrett runs a climate change website with fellow skeptic David Bellamy.

Barrett Bellamy Climate describes its main aims "One is the explanation of the greenhouse effect on as simple a level as is possible without being scientifically inaccurate. The second one includes advanced explanations with our 'translations' for general readers."

The site promotes science skeptical of man-made climate change. For example, Bellamy and Barrett describe the possibility that "the majority of the climate variations observed since 1750 have been caused by amplification of the solar radiation received by the atmosphere/Earth system."

 Publications

According to a search of 22,000 academic journals, there is a "JC Barrett" listed as a co-author of a single research paper on cloud densification published 13 years ago.

According to Skeptical Science, Barrett has not published any papers on climate that meet the definition of "Peer Reviewed." [8]

Barrett co-authored a paper with the UK climate change denier and former BBC broadcaster David Bellamy titled "Climate stability: an inconvenient proof" which was published in Civil Engineering in May, 2007. The paper sets out to prove that, even if there is a doubling of carbon dioxide in the next decade, it "will amount to less than 1°C of global warming."

In an article published in 1994 in the New Scientist he suggested that the lowest 30 metres of the troposphere already contains all the CO2 necessary to absorb all the radiation reflected and emitted back by the earth's surface at most infra-red wavelengths, except for the "window" between 7.5 and 14 micrometres, through which radiation escapes back into space. [3]

Other scientists have disagreed with him.
