Mann et al are being «hounded» for two major reasons: fraudulent manipulation of data to produce «results» that would support political actions advocated
by fellow «progressives» and conspiring with other prominent progressive
climatologists and organizations to suppress conflicting data
by trashing, personally and professionally, and blackballing the scientists who collected and
attempted to disseminate it.
As
climatologists attempt to create and improve upon exisitng models, this does not mean that the 3 and six box, STELLA etc... are to be discarded, rather the sensitivity of models, better if not perect modeling o clouds and ocean atmosphere interfaces, there always seems to be something that is lost in translation which is improved upon
by input of former models.
