There are a few things I have seen which stand out from reading about this. First off, it appears that the suspicions that the peer review process has been politicized to prevent criticism are valid, and if these documents/emails have not been tampered with there is solid evidence of this; and this should (basically) eliminate the argument that a lot of global warming supporters use that there isn’t peer-reviewed counter-evidence.
Beyond that, it appears that several laws have been broken surrounding FOIP and there may be grounds to arrest several of these (so-called) "Scientists". How well does the scientific-consensus argument hold up if the (so-called) consensus is maintained by illegally (and unscientifically) restricting access to the data?
Realistically, with this coming out now it should mean that the outcomes from the next climate conference should be a 10 year timeline to audit all the information available on "Climate Change" and determine how much of it has been tampered with. In this context, anyone who suggests any action to curb CO2 emissions that has any negative consequences should be tarred and feathered.
