Comment on Extreme variability: local climate change right now by Alex Nelson.

Well done, Evelynne Roullet (Posted March 1, 2017 at 11:59 am) for a most informative comment; and in the chronology you provided I was most taken by the entry for 1938 about British engineer Guy Callendar who showed from data obtained from numerous weather stations around the world that temperatures had increased compared to the previous century, a finding widely dismissed by meteorologists.
I compare this to the treatment meted out to German meteorologist Alfred Wegener who early last century compiled observations on geological and palaeontological evidence indicating the continents were once linked together. This information was well known but scientists generally accepted the explanation that there had been land-bridges between continents that had subsequently sunk below the oceans. In 1915 Wegener published a book proposing instead that the continents had once been all joined together and subsequently drifted apart.
This theory prompted huge controversy from scientists (especially in Britain, perhaps unsurprisingly) and basically the concept of continental drift was rejected on the basis of insufficient evidence and no explanation of any known force sufficient to move continents. Wegener was regarded as a crackpot, notwithstanding his reputation for research into polar climatalogy; and he perished for his work in Greenland in 1930.
It wasn’t until the mid 1960s when global mapping of the Earth’s ocean floors commenced that evidence came to light supporting the theory of continental drift. Mid-ocean ridges and alternate magnetic banding of seabed rock strata began the revelation of abundant evidence that the world’s land masses are indeed drifting on tectonic plates (incidentally, Australia is the fastest-moving continent on Earth). Today continental drift is completely accepted as a verified fact.
Wegener’s sad experience ought to be a salutory lesson to us all; and for myself it provides an extremely valuable analogy to the populist debate that swirls around the validity of evidence for climate change.
We discount or reject that evidence at our absolute peril.

Extreme variability: local climate change right now
This is a most important and timely story.
I’m one of those very few non-indigenous individuals who has lived here all my life. I was born in 1963 in the middle of one of the worst droughts on record. Since that time nearly every weather record in Central Australia has been broken, many of them more than once. Ironically, one record still standing since before my arrival is the hottest maximum temperature in the NT, set at Finke a couple of years earlier, but we’ve gotten close on occasion and it’s only a matter of time before that one falls.
One of the major impacts of the 1960s drought that reverberates to this day is the rise to dominance of buffel grass in Central Australia. The drought was a major impetus into extensive research to mitigate the enormous dust storms that frequently smothered Alice Springs, and buffel grass proved to be the ideal panacaea.
When I worked for the Rangeland Management Section at AZRI over a quarter century ago, one of the management problems for pastoral properties was how to deal with the problem of increasing “woody weeds”, especially mulga, witchetty bush and ironwood trees, which suppressed natural pastures and were largely resistant to control by fire, the only economically viable control method.
The increasing dominance of buffel grass across the region has, in my opinion, tipped the balance in favour of a major wildfire risk which, combined with the increasing severity of weather events, now poses an extreme hazard for us all in Central Australia. There have already been several serious wildfires in the vicinity of Alice Springs following above-average rainfall periods since the turn of the century, which I think are indicative of much worse to come.

Turn rock-throwing into backflips: how community can help
I smile at the circularity of Rainer Chlanda’s preferred location of a youth hub without walls at the “courthouse lawns” (DD Smith Park), adjacent to the Alice Springs Police Station (the former Greatorex Building) and across the road from the local magistrates courthouse.
I say “circularity” because the first drop-in centre for youth on the streets at night was located in the old police station on that corner where the courthouse now stands. Established in 1976, it was named “Danny’s Place” and lasted all of no more than a year when it was forced to shut down to make way for the said courthouse.
And from that time on, youth drop-in centres, real or proposed, have bounced around from one site to another all through town; including an old house in the north end of Todd Street that was demolished to make way for an office block (now called Eurilpa House), the empty Turner Arcade – the last shop there was Grandad’s icecream shop, a once popular hang out for kids of my generation, also in the north end of Todd Mall (that was my suggestion, nearly 30 years ago) which was later bulldozed to make way for expanding Alice Plaza and new carparking spaces; and even the abandoned waterslide site in the early 1990s, which instead was demolished to make way for infill real estate development (Mercorella Circuit, near the YMCA).
We have decades of recent history of kids in trouble (or causing it) being shunted from pillar to post. As a society, history shows we’re not really fair dinkum about resolving this issue.
Sadly, there is nothing new in any of this – Rainer’s father and his colleagues were reporting on these kinds of issues 40 plus years ago, and it continues unabated to the present day.


Wakefield insists on Anzac Oval, ignores majority
@ 5 Minute Local (Posted June 14, 2018 at 5:41 pm): Definitely living up to your pseudonym. Your suggestion is not a new idea – it’s been raised several times since the early 1970s.
The last occasion was when the construction of the railway north to Darwin was being finalised in the late 1990s-early 2000s when there was significant lobbying of the NT Government to re-route the railway around Alice Springs, including by the Alice Springs Town Council.
I also took up the cudgels on this issue as an individual and was publicly criticized by a local CLP member, notwithstanding the same member several years earlier had himself advocated the removal of the rail yards out of the town centre and to re-route the eventual railway to Darwin via west of the town.
These pleas were rejected by the government as being too late or too expensive (it would have added about three per cent to the overall cost, from memory). There’s no prospect of this happening now.

@ John Bell (Posted June 13, 2018 at 7:51 pm): John, the only sacred trees on the Melanka site would be (or are) two old river red gums near the southeast corner adjacent to the intersection of Stuart Terrace and Gap Road.
None of the other trees I’m aware of on that site are local native species nor predate the construction of the Melanka Hostel.
This includes the towering lemon-scented gums of which the majority are now dying or dead as a consequence of lack of care and the extended dry conditions.
Consequently the trees don’t pose any significant issues for redevelopment of most of that area, at least as far as sacred sites are concerned.


Wakefield insists on Anzac Oval, ignores majority
@ Hal Duell (Posted June 12, 2018 at 7:59 am): Hal, I’m still in the process of collating information. Gathering the history pertaining to this location is rather like measuring a piece of string but it all adds up to demonstrating the considerable heritage value of this site, the extent of which I think will surprise many people.
The nomination for heritage listing of the oval and school will definitely proceed.
The fact that this issue has blown up in the NT Government’s face demonstrates the stupidity of over-reliance on advice from vested interests (with no regard for anything except their bank accounts) and overpaid outside “experts” who have no background in local knowledge.
Once again we see the consequences of the corporate amnesia that afflicts this town and Territory, and history shows it makes no difference which party is in power.


Cemeteries could be turned into parks
There is another method of burying the dead which is also held to be environmentally friendly, it is called “promession”.
According to the Wikipedia entry on this subject, it’s a system of disposal of bodies of much more recent origin (two decades ago) than alkaline hydrolysis (19th century).
It involves cryogenic freezing of bodies in liquid nitrogen to -196°C (in effect, crystallising them) after which vibrations are applied that shatter them in minutes into fragments.
This material in turn is freeze dried and all metal or other non-natural components (eg. fillings, artifical joints) are removed.
The final stage involves “the dry powder being placed in a biodegradable casket which is interred in the top layers of soil, where aerobic bacteria decompose the remains into humus in as little as 6 to 12 months.”
Invented in Sweden, it’s a method already expressly adopted in South Korea and has expressions of interest from up to 60 other countries.
I think promession also deserves consideration as an option for burials.
