I really wonder if you've even read the links you provided, yourself...
Almost to a tee, most of those "cleared of wrongdoing" reports said the same thing over and over: Lack of evidence. Newsflash for ya, lack of evidence to prove wrongdoing does not mean nothing was done wrong.
Here is one nice little example, from one of the reports mentioned in Wanamingo's link:
"After careful consideration of all the evidence and relevant materials, the inquiry committee could not make a definitive finding..."
"All were impressed by Dr. Mann’s composure and his forthright responses to all of the queries that were asked of him."
(Wow, they are already blowing him at very beginning of this report document? How impartial and professional!)
"Throughout the interview, Dr. Mann answered each question carefully"
(OH, I see!! That was how the report's conclusions were made... they asked if he did, and he denied!! Investigation complete!!!)
"Given that information emerged in the form of the emails purloined from CRU in November 2009, which have raised questions in the public’s mind about Dr. Mann’s conduct of his research activity, given that this may be undermining confidence in his findings as a scientist, and given that it may be undermining public trust in science in general and climate science specifically, the inquiry committee believes an investigatory committee of faculty peers from diverse fields should be constituted under RA-10 to further consider this allegation."
"In 2006, similar questions were asked about Dr. Mann and these questions motivated the National Academy of Sciences to undertake an in depth investigation of his research."

Here's another funny gem from another report in Wanamingo's link:
http://www.uea.ac.uk/mac/comm/media/press/CRUstatements/SAP
"We saw no evidence... and had it been there we believe that it is likely that we would have detected it."
WOW!!! Now that is a definitive conclusion!! ROFL!!
The fact is that most of this was perpetrated by Phil Jones, and between his FoIA request obstruction, and claiming that the original data in question was "lost" (http://newsbusters.org/blogs/p-j-gladnick/2009/11/26/climategate-scandal-spreads-new-zealand-msm-continues-ostrich-act), it's really very very convenient to say oh yea we've our own independent investigations (by outside organizations that could not be biased in any way??? oops, no...) and we can find no evidence of anything. Well derka derka, it's hard to find data Phil Jones claims lost! "Manipulation of raw data is at the heart of recent claims of corrupt scientific practice in climate science, with CRU’s Phil Jones recently claiming old temperature records collected by his organization were “destroyed” or “lost”, meaning researchers can now only access manipulated data."

How can any of those investigations claim there was no influence on the science, when CRU was the base source of data that went out to many other organizations, and that original data is now conveniently gone? What is the basis for their conclusion, if the evidence that would prove the allegation one way or the other, is now "lost"?
Here are a couple beauties from Phil Jones himself:
"<2440> Jones:
I’ve been told that IPCC is above national FOI Acts. One way to cover yourself and all those working in AR5 would be to delete all emails at the end of the process"
"<1577> Jones:
[FOI, temperature data]
Any work we have done in the past is done on the back of the research grants we get – and has to be well hidden. I’ve discussed this with the main funder (US Dept of Energy) in the past and they are happy about not releasing the original station data."
That last one takes care of another convenient logical fallacy that the apologists here like to toss around: that no climate researcher could ever be influenced by the millions in grant money that flows around AGW, because while those researchers are fairly well off in comparison to most in America (and many in the world as well), they are by no means rich and would never let the global warming gravy-train influence their staunch ethics.
Oh wait... that 2nd Jones email I listed seems to directly refute that! Right out of the horse's mouth.
http://www.dailymail.co.uk/news/article-2063737/BBCs-Mr-Climate-Change-accepted-15-000-grants-university-rocked-global-warning-scandal.html
"A senior BBC journalist accepted £15,000 in grants from the university at the heart of the ‘Climategate’ scandal – and later went on to cover the story without declaring an interest to viewers.
Roger Harrabin, the BBC’s ‘environment analyst’, used the money from the University of East Anglia’s Tyndall Centre for Climate Change Research to fund an ‘ad hoc’ partnership he ran with a friend."
"In none of Mr Harrabin’s reports on the subject were the grants that he and his friend Dr Joe Smith had received from UEA ever mentioned."
"He said his report into the subsequent inquiry into Climategate, led by Lord Oxburgh (OH WAIT!!! That was the name of another "Independent" Investigation from the link Wanamingo put up!!http://www.uea.ac.uk/mac/comm/media/press/CRUstatements/SAP ), was praised for its ‘forensic impartiality’.
Disclosure of the payments to Mr Harrabin’s private partnership comes in the wake of a damning report last week by the BBC Trust Editorial Standards Committee."
http://www.telegraph.co.uk/comment/columnists/christopherbooker/8901365/The-BBCs-hidden-warmist-agenda-is-rapidly-unravelling.html
"Last week, even Richard Black, another BBC proselytiser for man-made warming, was gloomily having to reveal the conclusion of a new IPCC report: that, over the next few decades, “climate change signals are expected to be relatively small compared to natural climate variabilty”. In plain English, that means the great scare story is over. What a shame."
There is a lot of stinky fish lying around, smelling up this entire issue. If they wanna whine that now no one takes them seriously, then they should clean up/police their own and get back to rigorous ethical principles that should accompany ANYTHING in a scientific field. I will leave with a couple of emails that hit the nail on the head, once again from the mouth of the very horses involved in all of this:
"<3066> Thorne:
I also think the science is being manipulated to put a political spin on it
which for all our sakes might not be too clever in the long run."
"<2884> Wigley:
Mike, The Figure you sent is very deceptive [...] there have been a number of
dishonest presentations of model results by individual authors and by IPCC [...]"
^^ Exactly!! Need more be said??
