Patrick Courrielche of Big Journalism explores what Climategate means for the MSM. An excerpt:

How a tiny blog and a collective of climate enthusiasts broke the biggest story in the history of global warming science – but not without a gatekeeper of the climate establishment trying to halt its proliferation.
It was triggered at the most unlikely of places. Not in the pages of a prominent science publication, or by an experienced muckraker. It was triggered at a tiny blog – a bit down the list of popular skeptic sites. With a small group of followers, a blog of this size could only start a media firestorm if seeded with just the right morsel of information, and found by just the right people. Yet it was at this location that the most lethal weapon against the global warming establishment was unleashed.
The blog was the Air Vent. The information was a link to a Russian server that contained 61 MB of files now known as Climategate. Within two weeks of the file’s introduction, the story appeared on 28,400,000 web pages.
Not entirely the “death of global warming” as many have claimed – what happened with Climategate is much more nuanced and exponentially more interesting than the headlines convey. What was triggered at this blog was the death of unconditional trust in the scientific peer review process, and the maturing of a new movement – that of peer-to-peer review.
This development may horrify the old guard, but peer-to-peer review was just what forced the release of the Climategate files – and as a consequence revealed the uncertainty of the science and the co-opting of the process that legitimizes global warming research. It was a collective of climate blogs, centered on the work of Stephen McIntyre and Ross McKitrick, which applied the pressure. With moderators and blog commenters that include engineers, PhDs, statistics whizzes, mathematic experts, software developers, and weather specialists – the label flat-earthers, as many of their opponents have attempted to brand them, seems as fitting as tagging Lady Gaga with the label demure.
This peer-to-peer review network is the group that applied the pressure and then helped authenticate and proliferate the story.
Now, as expected, the virtual organism that is the global warming establishment resisted release of the weapon. At the first appearance of the Climategate files, which contained a plethora of emails and documents from the University of East Anglia’s Climate Research Unit, the virtual organism moved to halt their promulgation. Early on, a few of the emails were posted on Lucia Liljegren’s skeptic blog The Blackboard. Shortly after the post, Lucia, a PhD and specialist in fluid mechanics, received an email from prominent climatologist Gavin Schmidt from the NASA Goddard Institute for Space Studies (GISS). It said in part, “[A] word to the wise… I don’t think that bloggers are shielded under any press shield laws and so, if I were you, I would not post any content, nor allow anyone else to do so.”
