Just a few days ago (February 19), I posted part XX of this series. The subject of that post was a new compilation of historical temperatures for Australia (going back to 1910), known as ACORN2, just out from the Australian Bureau of Meteorology. The effect of ACORN2 was to increase the reported rate of climatic warming in Australia by 0.2 deg C per century over the previous compilation known as ACORN1, which had only been issued about 6+ years ago and had itself also increased the reported rate of warming as against the previous official records by about 0.2 deg C per century. The increased rate of warming is entirely accomplished by adjusting earlier-year temperatures downward.
Could there possibly be anything honest about what is going on? My source for the February 19 post — independent Australian researcher and blogger Joanne Nova — provided a link to the the BoM’s 57-page Research Report that supposedly justified the changes.
