During 2001 the IPCC made a number of predictions as to what would happen as a result of the climate change. At the time their results were widely mocked and ignored by the "climate change deniers" circles.
It now turns out that the actual effects measured today are _worse_ than what was predicted. For example, the rise of the ocean level is 80% greater.
I think people should concentrate on the larger picture -- the predicted effects are happening. The whole CRU emails issue is peanuts and only diverts the attention from the real issue, even if we assume that everything that is being claimed there is true.
