Adéu a Nihil Obstat | Hola a The Catalan Analyst

Després de 13 anys d'escriure en aquest bloc pràcticament sense interrumpció, avui el dono per clausurat. Això no vol dir que m'hagi jubilat de la xarxa, sinó que he passat el relleu a un altra bloc que segueix la mateixa línia del Nihil Obstat. Es tracta del bloc The Catalan Analyst i del compte de Twitter del mateix nom: @CatalanAnalyst Us recomano que els seguiu.

Moltes gràcies a tots per haver-me seguit amb tanta fidelitat durant tots aquests anys.

Descobrint els mentiders

L’exsupervisor de la NASA i científic de l’atmosfera John S. Theon s’ha declarat escèptic respecte l’orígen humà de l’escalfament global i ha acusat James Hansen, especialista en canvi climàtic i exassessor del vicepresident Al Gore, d’haver “avergonyit la NASA” amb les seves exageracions i sobre tot per haver falsificat dades i construït falsos models climàtics. Theon ho ha dit al comitè de mediambient i obres públiques del Senat nord-americà.

Recordem que Hansen va ser l’autor de les sèries estadístiques que “demostraven” que en els últims anys el món havia enregistrat les temperaturers més altes de la història. Unes dades errònies que va destapar Steven McIntyre, obligant a la NASA a modificar-les.

Reprodueixo tot seguit els mails enviats per Theon al comitè del Senat:

Subject: Climate models are useless

Marc, First, I sent several e-mails to you with an error in the address and they have been returned to me. So I'm resending them in one combined e-mail.

Yes, one could say that I was, in effect, Hansen’s supervisor because I had to justify his funding, allocate his resources, and evaluate his results. I did not have the authority to give him his annual performance evaluation. He was never muzzled even though he violated NASA’s official agency position on climate forecasting (i.e., we did not know enough to forecast climate change or mankind's effect on it). He thus embarrassed NASA by coming out with his claims of global warming in 1988 in his testimony before Congress.

My own belief concerning anthropogenic climate change is that the models do not realistically simulate the climate system because there are many very important sub-grid scale processes that the models either replicate poorly or completely omit. Furthermore, some scientists have manipulated the observed data to justify their model results. In doing so, they neither explain what they have modified in the observations, nor explain how they did it. They have resisted making their work transparent so that it can be replicated independently by other scientists. This is clearly contrary to how science should be done. Thus there is no rational justification for using climate model forecasts to determine public policy.

With best wishes, John

Subject: Re: Nice seeing you

Marc, Indeed, it was a pleasure to see you again. I appreciate the opportunity to add my name to those who disagree that Global Warming is man made. A brief bio follows. Use as much or as little of it as you wish.

John S. Theon Education: B.S. Aero. Engr. (1953-57); Aerodynamicist, Douglas Aircraft Co. (1957-58); As USAF Reserve Officer (1958-60),B.S. Meteorology (1959); Served as Weather Officer 1959-60; M.S, Meteorology (1960-62); NASA Research Scientist, Goddard Space Flight Ctr. (1962-74); Head Meteorology Branch, GSFC (1974-76); Asst. Chief, Lab. for Atmos. Sciences, GSFC (1977-78); Program Scientist, NASA Global Weather Research Program, NASA Hq. (1978-82); Chief, Atmospheric Dynamics & Radiation Branch NASA Hq., (1982-91); Ph.D., Engr. Science & Mech.: course of study and dissertation in atmos. science (1983-85); Chief, Atmospheric Dynamics, Radiation, & Hydrology Branch, NASA Hq. (1991-93); Chief, Climate Processes Research Program, NASA Hq. (1993-94); Senior Scientist, Mission to Planet Earth Office, NASA Hq. (1994-95); Science Consultant, Institute for Global Environmental Strategies (1995-99); Science Consultant Orbital Sciences Corp. (1996-97) and NASA Jet Propulsion Lab., (1997-99).

As Chief of several NASA Hq. Programs (1982-94), an SES position, I was responsible for all weather and climate research in the entire agency, including the research work by James Hansen, Roy Spencer, Joanne Simpson, and several hundred other scientists at NASA field centers, in academia, and in the private sector who worked on climate research. This required a thorough understanding of the state of the science. I have kept up with climate science since retiring by reading books and journal articles. I hope that this is helpful.

Best wishes, John
