Le débat concernant la question de la cause humaine au réchauffement climatique serait clos. Une récente lettre d’ingénieurs et scientifique de la NASA semble montrer le contraire.
Par Nathalie Elgrably-Lévy, depuis Montréal, Québec.
Nous avons entendu des milliers de fois que le débat entourant la question du réchauffement climatique est clos et que les scientifiques ont atteint un consensus sur la question. J’ai souvent dit qu’il est illogique de parler de consensus scientifique, car le propre de la science est justement de toujours remettre en question.
Voilà que, une fois de plus, la preuve est faite que le consensus n’existe pas. Plus que jamais, les scientifiques sont divisés sur la question du réchauffement.
Il y a quelques jours, une cinquantaine de scientifiques et d’astronautes de la NASA ont déclenché un séisme en déclarant que (ici et ici) :
– les données climatiques historiques ne permettent pas de confirmer la thèse du réchauffement anthropique;
– il n’existe aucun consensus;
– les déclarations de la NASA quant aux conséquences catastrophiques du réchauffement sont non fondées.
Le plus déconcertant, c’est l’attitude de la classe politique. Elle a vite réagit à l’éco-catastrophisme, elle est même devenu carrément hystérique (taxe carbone, ampoule, harcèlement des automobilistes, etc.)
Mais que fait-elle maintenant que la thèse du réchauffement est attaquée et discréditée ? Est-ce qu’elle suspend les couteuses mesures qu’elle a décrétées le temps de faire la lumière sur la question ? Pas du tout. Elle fait la sourde oreille.
Et que font nos médias ? Comme d’habitude, ils gardent le silence….
Voici le texte complet de la lettre rédigée par les 50 contestataires:
March 28, 2012
The Honorable Charles Bolden, Jr.
NASA Administrator
NASA HeadquartersWashington, D.C. 20546-0001
Dear Charlie,
We, the undersigned, respectfully request that NASA and the Goddard Institute for Space Studies (GISS) refrain from including unproven remarks in public releases and websites. We believe the claims by NASA and GISS, that man-made carbon dioxide is having a catastrophic impact on global climate change are not substantiated, especially when considering thousands of years of empirical data. With hundreds of well-known climate scientists and tens of thousands of other scientists publicly declaring their disbelief in the catastrophic forecasts, coming particularly from the GISS leadership, it is clear that the science is NOT settled.
The unbridled advocacy of CO2 being the major cause of climate change is unbecoming of NASA’s history of making an objective assessment of all available scientific data prior to making decisions or public statements.
As former NASA employees, we feel that NASA’s advocacy of an extreme position, prior to a thorough study of the possible overwhelming impact of natural climate drivers is inappropriate. We request that NASA refrain from including unproven and unsupported remarks in its future releases and websites on this subject. At risk is damage to the exemplary reputation of NASA, NASA’s current or former scientists and employees, and even the reputation of science itself.
For additional information regarding the science behind our concern, we recommend that you contact Harrison Schmitt or Walter Cunningham, or others they can recommend to you.
Thank you for considering this request.
Sincerely,
(Attached signatures)
CC: Mr. John Grunsfeld, Associate Administrator for Science
CC: Ass Mr. Chris Scolese, Director, Goddard Space Flight Center

… Il est illogique de parler de “consensus scientifique” sur le fait que la Terre n’est pas plate et que ce n’est pas le soleil qui tourne autour d’elle ? 🙂 Faisons un peu mieux la part des choses avant d’enoncer des sentences epistemologiques de bazar…
Par contre, il serait bon de s’interroger sur ce beau consensus de 49 personnes (qui, lui, necessairement, serait porteur de la verite ?) :
http://www.huffingtonpost.com/2012/04/13/nasa-climate-change-denier-stunts_n_1424492.html
“…none of the letter’s 49 signatories are climate scientists [from] more than 18,000 people currently working for NASA…”
“… Fake experts have been used extensively by the tobacco industry who developed a strategy to recruit scientists who would counteract the growing evidence on the harmful effects of second-hand smoke…”
« …none of the letter’s 49 signatories are climate scientists [from] more than 18,000 people currently working for NASA… »
Et donc?? La climatologie ne concerne pas que les climatologues, mais également des glaciologues, les cosmologistes, les thermodynamiciens etc etc…. Bref c’est un vulgaire argumentum ad potentiam
« … Fake experts have been used extensively by the tobacco industry who developed a strategy to recruit scientists who would counteract the growing evidence on the harmful effects of second-hand smoke… »
Ou comment faire de l’ad hominem en sortant complètement du sujet.
49 ? ils sont combien à la NASA ?

Un très bon article (comme d’habitude) qui permet d’ajouter une pièce au (très épais !!!) dossier de l’impartialité de la presse….
