News Corp behind Climategate?

Was Rupert Murdoch's right-wing-leaning News Corp behind the illegal hacking of the University of East Anglia's Climatic Research Unit? There's no direct evidence at this time, but Joe Romm has put it out there in today's Climate Progress [LINK]. While Romm's connections seem tenuous, there is no doubt that News Corp's news outlets made great use of the stolen emails, and no one would be surprised if the suspicion were to be found true. Either way, I think Romm's real point is that there have been so many investigations of the scientists tangled up in "climategate," but the actual crime remains unsolved. Who broke into UEA's computer system, selectively stole and then distributed emails from CRU? The motive is almost certainly political/idealogical, and whoever did it had some competence with "hacking," and some savvy about how to distribute the stolen information to the media... It would certainly bring closure to the whole affair if the perpetrators were brought to justice.
