Unfortunately, Climategate proved that, at least in the field of climate research, "peer review" is worthless; Mann et al were actively conspiring to ensure that only "friendly" eyes carried out the reviews; anyone thought to be showing signs of scepticism were blacklisted, whether individuals or publications.
To add to that, Glaciergate proved that much of what was claimed to be peer-reviewed was actually just regurgitated propaganda, often based on anecdotal evidence (reminisces of mountaineers published in a student rag? Puh-lease!)
So, appeals to authority ("oh but all this research has been peer reviewed") just don't hold any more. Not until all the data and all the methods used to arrive at the results are made available, and the results can be independently confirmed or denied, can we say whether the research was worth the weight of mouldy notebooks it was archived on.
