Ho risposto a Steph. A quanto pare .... a chi ?
RealClimate is a commentary site on climate science by working climate scientists for the interested public and journalists. We aim to provide a quick response to developing stories and provide the context sometimes missing in mainstream commentary. The discussion here is restricted to scientific topics and will not get involved in any political or economic implications of the science. All posts are signed by the author(s), except 'group' posts which are collective efforts from the whole team. This is a moderated forum.
Scusa che me ne faccio di Realclimate ? Uno come un altro, sono giornalisti.
Semplice: perché, nel post citato, mostra (riportando un post da RC scritto dal giornalistaPierrehumbert) come Spencer perda un po' di credibilità, avendo già voluto/dovuto "manipolare" qualche dato. Poi, per carità: magari è stato solo un caso....
Ah, per completezza ti avevo segnalato anche un recente lavoro di Kevin Trenberth.

Spiegami come mai sei pronto a scommettere su Pierrehumbert pensando che abbia "scoperto" un "trucco" di Spencer e che Spencer abbia usato un "trucco"!
E' una questione fideistica ?
Qualche altro scienziato ha avuto da ridire ?
Per me quello di Spencer ha la validita' che ha il lavoro di qualunque altro scienziato del settore e assume un forte peso il fatto che i suoi lavori escano dalla elaborazione delle risposte satellitari, che lui ha a disposizione su incarico della NASA. E non puo' certo essere un altro che agendo sul fatto che il lavoro non era documentato ha agito a suo piacimento:
Seguiamo la ricostruzione di Pierrehumbert del lavoro di Spencer.
Ricostruendo il modello di Spencer, e fissando i suoi parametri liberi in accordo con valori realistici di tali parametri così come derivano dalle osservazioni disponibili, Pierrehumbert giunge al grafico seguente.
.... senza parole.
Mi stucca un poco questo modo di screditare taluni e accreditare altri senza averne piena conoscenza e per interposta persona.
Se un lavoro o un dato proviene da una fonte non allineata allora e' sospetto, se invece viene da fonte allineata e' corretto ?
Non andiamo avanti in questo modo.
Questo re' il modo di affrontare le cose:

Ma, guarda, ognuno ha indubbiamente i suoi criteri per valutare la credibilità di scienziati e/o studi e certamente nessuno è infallibile.
Il sig Spencer sarà certamente un valente scienziato di grande esperienza, però lo riterrei più credibile, se certi precedenti non li avesse e se non fosse sul libro paga Exxon.
Marco Pifferetti Albinea - Reggio E.
http://marcopifferetti.altervista.org/index.htm
Quali precedenti ? Illustrati da chi ?
Hai visto il libro paga della Exxon ?
La scheda che lui ha nel suo blog dice questo:
Dr. Spencer’s research has been entirely supported by U.S. government agencies: NASA, NOAA, and DOE. He has never been asked by any oil company to perform any kind of service. Not even Exxon-Mobil.
Continuo a NON apprezzare il modo "aleatorio" con cui si affrontano queste discussioni.
C'e' chi ha deriso uno scienziato come Zichichi
C'e' chi ha sparlato di un ente come l'IPCC
C'e' chi ha pesato in modo diverso un dato con tanto di fonte di riferimento e studio citato perche' proveniente da "sito sospetto"
C'e' chi crede a quello che dice l'avvocato accusatore e chi a quello che dice il difensore
Pochi guardano ai dati e alle persone con apertura mentale e la giusta umilta'.
Anche lo studio del GW soffre di questo, dell'incapacita' umana di guardare alle cose con apertura mentale, obiettivita', curiosita' e umilta' .... e mi ci metto io per primo.
