More manipulating climate data

Oh hum, same old boring scientists-are-changing-the-climate-data story.  What's different is that now it's starting to be reported in the news media, Down Under at least:
One of the most extreme examples is a thermometer station in Amberley, Queensland where a cooling trend in minima of 1C per century has been homogenized and become a warming trend of 2.5C per century. This is a station at an airforce base that has no recorded move since 1941, nor had a change in instrumentation. It is a well-maintained site near a perimeter fence, yet the homogenisation process produces a remarkable transformation of the original records, and rather begs the question of how accurately we know Australian trends at all when the thermometers are seemingly so bad at recording the real temperature of an area. Ken Stewart was the first to notice this anomaly and many others when he compared the raw data to the new, adjusted ACORN data set.  Jennifer Marohasy picked it up, and investigated it and 30 or so other stations. In Rutherglen in Victoria, a cooling trend of -0.35C became a warming trend  of +1.73C. She raised her concerns (repeatedly) with Minister Greg Hunt.

Now the Australian Bureau of Meteorology has been forced to try to explain the large adjustments. Australians may finally gain a better understanding of what “record” temperatures mean, and the certainty ascribed to national trends. There is both a feature and a news piece today in The Weekend Australian. – Jo Nova The heat is on. Bureau of Meteorology ‘altering climate figures’ — The Australian
Here's what "peer-reviewed climate science" looks like:

In other the-data-are-bad news, the National Climate Data Center's feed of record temperatures has gone missing.  Is it a regular government screw up, or is it because cold records outnumber warm records by three to one this summer?  The World wonders,  But don't you dare question the white lab coat Priests of the Great Warming, prole.  Pay no attention to the crummy data everywhere.  Know your place.

All I know is that we're in the middle of the wettest August since 1899, and today I'm seriously contemplating taking off my shorts and putting on long pants.

Yep, the inconvenient truth... Can't have THAT!
