Hm, peut-être faut-il savoir si le réchauffement climatique est réellement dû à l'homme ?
Apparemment, ce n'est pas l'avis de 31 000 scientifiques qui ont signé une pétition pour dire que le réchauffement climatique n'est pas anthropique.
Alors ? Les 2500 du GIEC ou les 31000 de la pétition ? (http://www.petitionproject.org/
Qualifications of Signers
Signatories are approved for inclusion in the Petition Project list if they have obtained formal educational degrees at the level of Bachelor of Science or higher in appropriate scientific fields. The petition has been circulated only in the United States.
The current list of 31,072 petition signers includes 9,021 PhD; 6,961 MS; 2,240 MD and DVM; and 12,850 BS or equivalent academic degrees. Most of the MD and DVM signers also have underlying degrees in basic science.
All of the listed signers have formal educations in fields of specialization that suitably qualify them to evaluate the research data related to the petition statement. Many of the signers currently work in climatological, meteorological, atmospheric, environmental, geophysical, astronomical, and biological fields directly involved in the climate change controversy.
The Petition Project classifies petition signers on the basis of their formal academic training, as summarized below. Scientists often pursue specialized fields of endeavor that are different from their formal education, but their underlying training can be applied to any scientific field in which they become interested.
Outlined below are the numbers of Petition Project signatories, subdivided by educational specialties. These have been combined, as indicated, into seven categories.
1. Atmospheric, environmental, and Earth sciences includes 3,697 scientists trained in specialties directly related to the physical environment of the Earth and the past and current phenomena that affect that environment.
2. Computer and mathematical sciences includes 903 scientists trained in computer and mathematical methods. Since the human-caused global warming hypothesis rests entirely upon mathematical computer projections and not upon experimental observations, these sciences are especially important in evaluating this hypothesis.
3. Physics and aerospace sciences include 5,691 scientists trained in the fundamental physical and molecular properties of gases, liquids, and solids, which are essential to understanding the physical properties of the atmosphere and Earth.
4. Chemistry includes 4,796 scientists trained in the molecular interactions and behaviors of the substances of which the atmosphere and Earth are composed.
5. Biology and agriculture includes 2,924 scientists trained in the functional and environmental requirements of living things on the Earth.
6. Medicine includes 3,069 scientists trained in the functional and environmental requirements of human beings on the Earth.
7. Engineering and general science includes 9,992 scientists trained primarily in the many engineering specialties required to maintain modern civilization and the prosperity required for all human actions, including environmental programs.
The following outline gives a more detailed analysis of the signers' educations.
Bon ben faut les croire sur parole, et gober que les pétitionnaires aient décliné leurs qualifications... en ligne ou bien ça a été vérifié ? Mais sinon, oui le GIEC c'est du caca. Le nombre fait foi
The "Oregon Petition", self-signed and unverified by third party, was started in 1998 by physicist Frederick Seitz, past president of the United States National Academy of Sciences. The identical petition card was circulated again in late 2007 and Arthur B. Robinson presented the petition of 31,000 claimed signatories in Washington DC on May 19, 2008. Critics point out that many of the signatories of the petition lack a background in climate-related sciences and that the petition itself mentions only "catastrophic heating" and not the broader issue of global warming. The petition's website claims that all of the 31,000 signatories are qualified scientists with "technical training suitable for the evaluation of the relevant
research data." However, anyone with a degree was entitled to sign the list and this would therefore include many who are not qualified to evaluate the complex data and modelling involved.
éa a l'air super sérieux

Non non, pour la question du réchauffement anthropique ou pas, c'est pas une question d'opinion, c'est une question scientifique.
Avec des pressions énormes jusqu'à aujourd'hui pour que les conclusions aillent dans le sens de "l'homme n'y est pour rien". Le scepticisme en matière de RC, c'est l'œuvre du discours dominant.
