Suppose further that the Japanese government convinces your largest importer the US, say to strengthen its currency to avert a further Japanese economic disaster, and that the prices of your export goods become relatively unattractive because your currency is pegged to the dollar.
How accurate are our national climate datasets when some adjustments turn entire long stable records from cooling trends to warming ones or visa versa?
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. 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. 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.
There is both a feature and a news piece today in The Weekend Australian. The odd case of Amberley minima. If you live nearby the local thermometer would say that mornings now are slightly cooler for you than they were in The BOM says otherwise.
Both Jennifer Marohasy and Graham Lloyd are both doing great work here: After a description of some of the problems, the BOM responds to explain the adjustments. It said the level of confidence was very high because of the large number of stations in the region.
There were examples where homogenisation had resulted in a weaker warming trend. But the radius of those stations is nearly 1, km. These other sites may themselves have had real warming, or an urban heat island effect, or other equipment changes or relocations.
The BOM rarely portrays how complicated and messy it is, nor how much the final trends are affected by their complicated adjustment processes. At Burke, in western NSW, BoM deleted the first 40 years of data because temperatures before were apparently not recorded in a Stevenson screen, the agreed modern method.
Marohasy says this could have been easily accounted for with an accepted algorithm, which would not have changed the fact that it was obviously much hotter in the early 20th century than for any period since. Instead, the early record is deleted, and the post data homogenised.
She is a biologist and a sceptic of the thesis that human activity is bringing about global warming. Read it all though it may be paywalled:As you might know, I haven’t been exactly the world’s most consistent fan of the Social Justice movement, nor has it been the most consistent fan of me.

Every time President Isaias Afwerki has an interview with his captive media (Eri-TV), a very large segment of the population take the very sensible decision of ignoring it, leaving a few of us obsessive types to watch it and divine meaning from it.
