Al Gore effect strikes Brisbane G20 weather forecast – Bureau of Meteorology called for 40°C but Brisbane only got to a warm 32

Saturday morning after 9am the ABC news 24 TV presenters crossed to a BoM staffer from Melbourne and they all talked about a possible record breaking day for Brisbane which had a forecast of 40. Oddly none of them including the BoM guy could quote what the record was (takes 20 secs online to find out). Brisbane Regional Office hit 41.2 in November 1913 – that is the record – nineteen thirteen!!! They are forecasting 40 again for Sunday – might be luckier. On Saturday Brisbane topped at 32 near 1pm but NE breezes moderated the afternoon. Amberley and Gatton further west did hit 40 and Amberley got a record 43. It was also interesting to hear TV news people Saturday evening all faithfully mentioning the “hot day” in G20 reports.

  1. “”The first point I want to make … is that Australia has always believed that climate change is real.” T. Abbott.

    Will you be jumping on board too Warwick?

    Ps it was hot EVERYWHERE today in BrisVegas- not just in 80% if the city like yesterday.

  2. Interesting to note that the nightly weather news hype for Brisbane has suddenly lost interest in “under performing” Brisbane and switched focus to a map showing nearby station “hottest evahs” which they flashed across our TV screens. It might be interesting to know the duration of the temperature data sets for these stations and what “adjustments” have been inflicted on those data?

  3. Its not hard to find out. Amberley opened in 1941. And I get tired of saying over and over and over again – individual site statistics are not adjusted – if its a record then its a record. I’ll say it again – individual site statistics are not adjusted in the official record.

    Just in case you missed it – individual site statistics are not adjusted in the official record.

    If you need is to understand how the climate is changing – then you need to understand how site measurement characteristics have changed – and you may (will) need to adjust data. Very, very, very few sites will survive unadjusted when trying to determine how the climate has changed.

    But just in case you missed it – individual site statistics are not adjusted in the official record.

    Do you mean that statistics are not adjusted in the CDO (agree) or not adjusted in the official record for ACORN stations (don’t agree)?

  5. So what do you think Amberley’s November 1913 mean maximum might have been George? Just curious.

    Every observing site has an official record that remains unchanged. Record maximma and minima, monthly temperature averages, wind speeds, rainfall averages operate off that data set. Every observing site. Each and every one.

    To inform on climate change some of that data from some of those sites is extracted and post processed – it is acornsat. It has nothing to do with reporting on record maxima or minima.

    Not as hot as November 1915 was at both Gatton and Ipswich.

    George.

    Wrong. ‘The bureau on Tuesday raised its estimate of an El Nino occurring this summer to “at least 70 per cent”‘

  8. The weekend of the Brisbane G20 falls short of the heat of several periods looking back over more than a century.
    Daily data from Brisbane Regional Office 40214 (1887-1986) shows the following 2 day hot periods in November exceeding the G20 weekend heat which was 32.2 and 38.9.
    1898 – 13th & 14th – 40.8 & 32.9
    1904 18th & 19th – 33.3 & 40.
    1913 17th & 18th – 36.1 & 41.2 – this is the all time record.
    1915 14th & 15th – 33.8 & 40.7.
    1928 8th & 9th – 32.4 & 39.4.
    1967 23rd & 24th – 36.1 & 39.4.
    However the Brisbane November heatwave that dwarfs all others is from –
    1968 where 5 days – from 17th to 21st saw – 34.1, 36.7, 40.8, 37.7, 35.9.

    Brisbane stations post 1986 saw nothing hot enough to make this list until last weekend.
    Interesting to hear Barrie Cassidy on his Insiders show Sunday morning on ABC News24 TV say – “climate change comes to Brisbane”. What can be done to prevent such misinformation being spread?
