what I've heard is that this is merely a single data set that was manipulated and not even really in the way that the nutcases are actually describing
I followed the scandal very closely, and there's absolutely nothing to it. There aren't even any serious accusations of scientific errors being investigated.
The biggest fuss was about what the emails referred to as "using Mike's 'Nature' trick to hide the decline." The climate change deniers and much of the media ran with the suggestion that the "decline" was a decline in global temperatures, and that they were somehow trying to hide it from the public. In reality, the "decline" was in one series of tree ring temperature data that isn't reliable for the latest few decades. It was "hidden" in plain sight by putting it next to the actual thermometer temperature record for those years, on the same graph, clearly labeled. What the statement
really meant--and there is no disputing this--is that he put the apparent-but-artificial temperature decline in the tree ring series in context by showing it next to the real thermometer temperature data.
Of course, that
real explanation was rarely mentioned on the news. This is why I think the mainstream media is so incredibly biased toward right-wingers. They aren't
trying to be biased (except for Fox of course). Most reporters are probably
personally left of center. But their style of "balanced" reporting, in which they neutrally parrot each side's talking points with equal weight in "he-said, she-said" fashion, plays right into the hands of whichever side does the most egregious lying. Their bias toward headline-grabbing controversy also works in the right wing's favor. A proverb sometimes attributed to Mark Twain says, "A lie can travel halfway round the world while the truth is putting on its shoes." The media's job
should be to research the truth and use it to stamp out lies. Instead they report the truth and the lies as equals and say things like, "We report, you decide." Then they have pundits come on to shout the lies for half an hour at the top of their lungs.
There was
absolutely nothing even remotely sketchy about the "Mike's Nature trick" email. It's not a matter of opinion, not open for personal interpretation of any kind. It was just a choice of words in a
private email that would make perfect sense to the recipient, but looks awful when pulled out of context (by illegal hackers, no less). It was picked up by useless right-wing demagogues and paraded around as some massive scientific fraud, and the media not only let that happen, they helped out! They went on for days and days like this was some sort of big controversy, parroting the out-of-context line for discussion without any hint at what it really meant. There really should be hundreds of reporters fired for being complicit in that nonsense, but unfortunately it's just par for the course.
