Fact Checking the Climate Council 7


The Climate Council mini-statement called Bushfires and Climate Change in Australia – The Facts states in support of their view that “1. In Australia, climate change is influencing both the frequency and intensity of extreme hot days, as well as prolonged periods of low rainfall. This increases the risk of bushfires.”

Southeast Australia is experiencing a long-term drying trend.

A moment of fact-checking the BoM recorded rainfall in Southeastern Australia reveals no trend in rainfall.

Another moment of fact-checking the BoM recorded rainfall in Australia reveals an increasing rainfall trend.

Fail.

    David,

    You might have seen these graphs where I took Melbourne & Sydney as long duration stations, then calculated the ‘hottest’ periods of 6 consecutive days from daily Tmax. Neither the average Tmax of the heat waves so defined nor the frequency of occurrence of the heat waves over the years since 1860 or so, seems to have any pattern in Januaries or Februaries apart from a few fewer before 1890.

    The highest 14-15 averaged heat wave values are displayed on each graph.
    The rough conclusion is that such heat waves are not becoming more frequent, especially as these daily figures are not adjusted for UHI.

    Sitting ducks once again. So often, all that is required to refute these ‘on-message-for-the-scamsters-and/or-zealots’ claims is merely to take a look at the most relevant data. How much longer can the edifice built on hyperbole over CO2 persist given the intellectual rot at its core and on its most visible features?

    where is the statement:

    Southeast Australia is experiencing a long-term drying trend
    has it been removed?
