The sunburnt country is awash

Record-breaking rain means huge Australian arid-land lakes are visible from space.

Australia has one of the most unpredictable rainfall patterns in the world, and this is one of those unpredictable years. For the past few months, the repeated downfalls have left large pools of water lying in arid lands in Western Queensland. It’s great news for farmers. The water will, over the next year, flow south through the Darling River system, restoring parched watercourses, swamps, and dams. The Darling River system flows from Queensland through New South Wales and into South Australia.

Earlier this month, the Bureau of Meteorology announced that the rains were “exceptional”:

The most remarkable aspect of this event was the area covered by the heavy rainfall and the total volume of rainfall that fell. Daily totals exceeded 100 mm over 1.7% of Australia on 1 March and 1.9% on 2 March. The latter is the largest area of 100 mm-plus daily totals on a single day in the Australian meteorological record, breaking the previous record of 1.7% set on 22 December 1956. 28 February was the wettest day on record for the Northern Territory with an NT-wide average of 29.23 mm, while 2 March set [...]

The BOM & CSIRO report: It’s what they don’t say that matters

Ken Stewart has scanned the trend maps at BOM (Bureau of Meteorology), and his point is spot on. As soon as I saw the neat joint six page advertising pamphlet for the climate-theory-backed-by-bankers, I wondered what happened to the first 60 years of last century, and Ken found it. Did the BOM forget they have hundreds of data points from back then? Did they forget to use their own Website, where you can pick-a-trend, any-trend, and choose the one with err…more convenient results? Or is it the case that their collective mission is not necessarily to provide Australians with the most complete and appropriate information available, but with what the bureaucracy needs them to know? And what they need them to know, apparently, is the carefully censored version of the truth that will keep government ministers happy (Let us tax them more!), keep department heads smiling (Let the climate cash cow continue!), and last, but not least, help staff feel good (We’re sure we’re helping the environment!).

Why censor half their own data?

The trend map page works exquisitely well (I am happy to praise the BOM Web site team). Compare these two trend maps:
