Comment on Extreme variability: local climate change right now by Hal Duell.

There is an article in today’s Guardian on-line edition that speaks about the shrinking sea ice in the Arctic. It contains the following sentence which, perhaps, goes to the heart of the debate about global warming.
“The ice’s disappearance – triggered by global warming caused by rising carbon emissions from cars and factories –…”.
It’s hard to argue with the stated fact that the sea ice is shrinking. Satellite imagery proves that point. The question is why. The further question is what, if anything, we can do about it?
Locally, summers are hot and winters are cold. It has always been so.
I don’t know if our summers are hotter and our winters are colder, but that globally the weather is more volatile today than it was yesterday also seems to be beyond dispute.
Again, what, if anything, can we do about it? Probably not much.

Extreme variability: local climate change right now
@ Harold, posted March 6, 2017 at 8:05 am:
I dispute that my comment “Locally, summers are hot and winters are cold. It has always been so.” is an alarmist argument.
Quite the contrary. I suggest it is anything but alarmist.


Extreme variability: local climate change right now
I am looking forward to the public debate advertised for next Monday between 5pm and 7pm at the Alice Springs Convention Centre.
One question that I hope someone will address is the suggested leaking of methane gas into the atmosphere during and after the fracking process.
Another question that has been rolling around in the back of my mind for some time now, and which is probably beyond the scope of this coming debate, concerns subsiding.
Sink holes are in the news more and more these days. While it admittedly sounds a bit like something out of science fiction, are we destabilising the earth’s crust (which we live on) by taking more and more out of the crust in the form of water and hydrocarbons?
This probably goes to the larger question of can we continue to assume the wholesomeness of this planet despite the unprecedented number of humans living here poking and prodding and generally treating it as an inexhaustible milch cow?

Make September 8 Australia Day, anthem in Pitjantjatjara
Has anyone asked the descendants of Matthew Flinders what they think of the proposal to bring his remains to Australia? I hope so, as surely common courtesy would make that a first step.
Just asking …


Adelaide’s Indigenous gallery out of the starting blocks
This is a good move from the perspective of a National Indigenous Art Gallery.
An excellent location in a capital city with ready access for national and international visitors. There’s lots to see and do in Adelaide. I predict it will be a huge success.
In contrast, let’s look at Alice. We may love it – I certainly do having lived here for forty years with no plans of leaving.
But aside from access to some unique country, what do we offer our visitors? Here’s a clue: Go into town on any day and watch the loud and aggressive drunks stumbling about making fools of themselves.
Or how about spending an hour or two in the Coles car park any night you choose? Not exactly a good look!


Planning another plan
To further develop the CBD without first addressing flood mitigation would be leaving the cart before the horse and a blueprint for future heartbreak.


Make Oz Day a celebration of the future, not the past
Domenico: Please stop misquoting me. I do not and have not suggested Anzac Day be also known as Australia Day.
“If (IF!) we want a national day to celebrate our coming of age in the crucible of war, Anzac Day amply suffices.”
No one, myself included, has suggested we meld that day into Australia Day.
You are doing your argument no favours by resorting to underhanded and misleading rhetorical tricks.


Make Oz Day a celebration of the future, not the past
Domenico: Perhaps we need to think again on what constitutes an acceptable national day, or day of unity.
We already have a designated Federation Day, but does anyone really pay much attention to it? And falling as it does on the day after the global party of New Year’s Eve makes it hard to imagine it becoming anything more than what it already is.
If we want a national day to celebrate our coming of age in the crucible of war, Anzac Day amply suffices.
My suggestion of the last Monday in January was mostly to offer a minimal alternative to January 26, which will never be accepted by many.
Following comments to my letter, I am coming around to the idea of September 1, or Wattle Day.
It is politically neutral, it is the first day of Spring, it celebrates the green and gold, and it allows for the participation of schools and school children.
Not a bad combination when celebrating the present and looking to the future.
