  1. Just now watching ABC TV 7pm news repeating the 1 in 100 year line. They also then had showed a BOM spokesman repeating it, I think he said “1 in 100 year threshold”

  2. Since, not so long ago, the BoM was saying that good rains wouldn’t come until April this must be a “1 in 100 year” event.
    After all, how many predictions by the BoM have been abject failures? (Responders must limit themselves to the last 2 days).

  3. Right Graeme No.3 anything beyond the 24 hour news cycle is a real stretch these days it seems on their ABC. Auntie now caters pretty much exclusively for the attention span of the Twitterarti mob.

  4. I live in SE Qld, A few weeks ago I was at a resort in the Gold Coast Hinterland and noticed their average rainfall going back to about 1911 was almost the same for every month at my place north of Brisbane. Here are some of my figures. In Dec 2010 I had for the month of Dec 668mm (a record over 125 years) then in Jan 9 to 12 2011 when the were floods in Brisbane, Toowoomba, Gold Coast and Sunshine Coast we had 412 mm. On 25 Jan 2012 I had 195mm, In 2013 on 27 Jan I had 216mm and 25th to 28th Jan there was 484mm. On 28th Jan 2014 there was 166mm. Getting 200mm in a day during the rainy season of Jan, Feb and Mar. is nothing special. The record short term rainfall occurred in 1893 (of over 1m in 3 days), when there was a cyclone called the Mooloolah event which caused huge floods in Brisbane and the Sunshine Coast.

  5. I should have looked up the Mooloolah Event first This is from a Google search
    The 1893 floods were the outcome of the “Mooloolah rainfall event”, the highest recorded rainfall in south-east Queensland to that date, with 1,715 millimetres (67.5 in) of rain falling in 72 hours.

    Phew ! I’ve been around a bit (Q’ld, all round tropical belt, PNG) but never experienced that.

  7. I imagine I’m not Robinson Crusoe in being very ordinary in reaction to the ABC’s continual hysterical nagging. Used loo paper has more value.

  8. There is no hope for sensible Govt in Australia as long as the taxpayer funds the utterly unbalanced GreenLeft ABC.
    Yet there seems not the slightest hope politically of any moves to either bring “balance” to the ABC or defunding it.

  9. BOM shouldn’t be off the hook either.
    Almost every day we see BOM’s scientists mincing on ABC TV, inferring (nod, nod, wink, wink) that Armageddon is nigh, continually dreaming up new contortions of the data to create new ‘records’, and to infer support for their climate change thesis.
    How can we, the public, feel confident that the BOM staff, so committed to the ’cause’ and governed, like, ABC by ‘group-think’, will also put all this zealotry aside when there are opportunities to put a ‘thumb-on-the-scales’ of measurement?

  10. I agree Jim that BoM are biased and mesh with the ABC to promote their agenda. It is amazing that next to zero pollies take them on.

    >” … not the slightest hope politically of any moves to either bring “balance” to the ABC or defunding it”

    Politicians (almost all) are too scared of the pounding the ABC and Nine publicity outlets subject them to. And note that the slightest suggestion of reduced funding for the ABC brings out a “give us the money or the kiddies get it” threat – kids’ programmes are shamelessly used as blackmail.

    These tactics work a treat because enough of the general populace believe the propaganda – this cannot be changed. As I’ve noted, the geology/geography of the country herds most of the population into a few cities where it is easy to harp on their fears. Where are the votes, does one need to ask ?
