Should IPCC be Replaced by The Royals?

The Guardian concludes in The case for climate action must be remade from the ground upwards that

• The IPCC panel should arguably be replaced by a body controlled by national scientific academies rather than governments.
  

This is because IPCC has lost all scientific credibility. Fine, IPCC should be dismantled. But is it such a good idea to hand over to the Royal Society of London and the Royal Swedish Academy of Sciences? 

Probably not, because the Royals have been very loyal supporters of IPCC  all along and have been keen to express official endorsements of IPCC, which have not been revised because of Climategate and all the other scandals connected to IPCC and its chairman Pachauri.  

Not yet at least, but the time to leave the sinking ship is near, right?

Obama plans a new Federal Office for Global Warming:

• This service will be a vital part of our growing body of knowledge on climate change, and will be held to the highest standards of scientific integrity and transparency.

Convincing? According to Obama science is settled. But it is not. And there never was any consensus.  IPCC have done fundamental mistakes, but the evidence is clear, nevertheless?
