The ABC reports – Collapse at Clarence Colliery at Lithgow ‘equivalent to giant oil spill’, wilderness foundation says.
I wonder if in all history rivers and creeks have never eroded coal measures before? So are there natural examples of environmental damage equal to “giant oil spills” in the rivers and water courses draining the abundant coal measures surrounding greater Sydney?
Not trying to minimise any particular event but let us keep some perspective and it would be nice to see the media reporting a rational view from all angles.

Australian BoM claim that Perth has had the warmest June ever is not true everywhere around Perth
Keen eyed readers warned me of this news – Warmest June temperatures for Perth
Working down this station list for the Perth region – In a few days the June 2015 archive will be visible. I have the page saved offline if anybody wants it emailed. Badgingarra had 20.6 last month but in 1985 saw 20.9.
Garden Island had 19.9 equal with 2006. Gingin Aero has 20.9 but saw 22.9 in 1996 and 21 in 2000. Karnet had 17.8 but saw 18.1 in 2006. Rottnest Island at 19.7 was equal to 1997.
Looking around at other stations some closed – Guildford Post Office saw 21.3 in 1944. Upper Swan Research saw 21.6 in 1983. Rottnest Lighthouse read 20.2 in 1949.
I ask if you could take out a century of urban heat island UHI growth – would the BoM claim stand up? I think on balance no doubt last month was very warm in Perth but the claim of “warmest ever” is not the most robust of claims to trumpet from the centre of a huge urban area.
Australian BoM names Raquel as their first ever recorded July cyclone – but BoM memories are faulty
The BoM has said that a tropical low north east of the Solomons might develop into a tropical cyclone. First news on 30 June.
There are references to July cyclones if you search the National Library of Australia online newspaper database TROVE – as reader silligy has done and kindly emailed.
I would guess that most usages of the term cyclone refer to inconvenient wet weather that was not due to what we would term a “tropical cyclone” these days.
However a SE Qld event from 11th to 14th July 1954 reported in the Ipswich based Queensland Country Life has the hallmarks of being due to a borderline Category 1 tropical cyclone. Readers can judge for themselves and who knows better examples might lurk within TROVE.

Here is a rain anomaly map for July 1954.
Checking Daily max wind gusts – yes on 12th July 1954 Brisbane RO and Airport both topped 100kmh max gust which I think puts it in Cat 1 class. Bearing in mind winds might have been higher at sea and at the lighthouses if data existed – and even higher if modern BoM wind speed models could be applied.
However, due to increasing demands of supplements, many people take advantage of this and try cheapest viagra to sell fake supplements that they claim to have positive effects on ED.

Stop Press – Just found these headlines at Trove – you can find the 14th.
Trove has no Courier Mail for the 13th
But the 14th –
The BoM is a disgrace – too often misinforming Australia about our weather history – the BoM must be reformed.
