The hiding of cooling was implied in the problems in the data/models. It’s a moot point really, the scientists did some dodgy stuff, whether they were exaggerating warming or hiding cooling doesn’t make much difference to their integrity.
How could cooling be implied from climategate leaks, when climategate deniers where saying "There is no relationship whatsoever between human activities and climate change."?
If the leaks show that some models and data were ignored that show cooling then you can imply that they were hiding cooling.
You can also imply that their warming models and data reconstructions were not very accurate. Either way many climate scientists have a history of shadiness, just look at all the Dr Mann lawsuits pending.
