Heh...Might be tougher than they think since the original data was lost (or intentionally destroyed)...
I’m sure their investigation will therefore conclude that the results are correct (assuming that those investigating are looking for grants themselves (probably) - heh)...
Not necessarily. The CRU copy of the data may be lost, but the entities that they originally got the raw data from probably still have copies. They may come under considerable pressure to not re-release the data if an unbiased examination makes Global Warming come into doubt.
