It's Unofficial! Brisbane's coolest Spring ever.

For the first time ever in Brisbane's climate record, the city has had an entire Spring season without a single temperature over 30C. Brisbane temperature records go back to around 1900.

It is now the last day of Spring and the temperature hit 26.8C at 3p.m. Now it is 5p.m. and the temperature has fallen to 24.7C. Although the final day of Spring has some seven hours to go, short of a volcano erupting in the Brisbane River, a new cold record has been set. September + October + November 2010: zero days above 30C.

By way of comparison, in October 2009 there were four days above 30C. In November 2009 there were 13 days above 30C, for a total of 17 days in all, or over a quarter of days of those months. Four of these exceeded 34C. Sorry, no September 2009 data: for some reason known best only to themselves, Australia's Bureau of Meteorology website doesn't have any daily data that ancient, being, apparently, unable to pop down to the local Harvey Norman and spring $100 for a new terabyte disc drive. Whether the September 2009 data is censored, deleted, or stored on floppies will remain one of those inscrutable cosmic mysteries.

But good news! They have a new "high-quality" data set suitable, they say, for climate change research. Here's a sample, the "Annual Maximum Temperature" for Brisbane Aero - presumably the airport. Maybe someone can enlighten me what these numbers are meant to be, because they certainly aren't Brisbane maximum temperatures which, as any Brisbanite knows, go infallibly way into the 30s every summer:

But here's the thing: Does that graph look pretty flat to you? Where's the global warming? For what it's worth, here's that graph with a trend line marked on it: note the downward slope!

Has the BOM really reformed and broken the shackles of the warmist ideology? Let's hope so.
