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

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?

Just a question, but can council block these developments? I thought development consent came from Darwin.


Pine Gap and the Nobel prize the Oz government ignores
Thank you, Russell, for sharing your family’s history. Your grandfather showed great foresight in first getting out of Germany and, later, moving to Australia.
Back to the present, and while I repeat that the Nobel Peace Prize being given to the International Campaign to Abolish Nuclear Weapons came as a most welcome bolt out of the blue, I can see one big problem in trying to implement its agenda.
Looking at the world today, the hot wars are being waged against countries without nuclear capabilities. These are mostly across the Middle East and in north and sub-saharan Africa. No one is seriously contemplating starting a hot war against countries with a nuclear deterrent, whether they be the big three of Russia, China and the USA or the second tier countries of England, France, India, Pakistan, North Korea and Israel, blustering and posturing notwithstanding.
Looked at in this light, having nuclear weapons makes good sense. Would that it were not so, but, unfortunately, it is.

No argument with what you say about the war in the Pacific, but try as I might, I cannot place that theatre between Japan and Germany.
I can, however, place Mao’s Eighth Route Army there, but if we are to look at that it would mean opening a whole new chapter into who did what in WWII.
As to stability, the Korean war waged from 1950 to the present day has not brought stability, the war in Vietnam did not bring stability, the current kerfuffle in the South China Sea is not bringing stability and the annual Talisman Sabre is not bringing stability.
However, Nixon’s visit to China in 1972 did open a road to stability, but that was an exercise in diplomacy, not sabre rattling.

An interesting comment below that the only thing standing between Russell’s father and the Japanese was the strength and commitment of the USA.
It might be more accurate to say that the only thing standing between Russell’s father and the Japanese was the Soviet army.
The Wehrmacht was broken at the battle of Stalingrad (today’s Volgograd), not on the beaches of Normandy, an inconvenient truth, but the truth nonetheless.


Pine Gap and the Nobel prize the Oz government ignores
Being in my own way an optimist, when Trump was elected President of the US I had hopes that he really would get out of foreign wars, make nice with Russia and rebuild America’s crumbling infrastructure. Instead he seems to be locked into waging yet more wars, demonising Russia and destroying infrastructure (and how many lives and hopes and dreams?) in other lands.
Foolish me!
But there may still be a silver lining to the cloud of Trump’s presidency. All over the world people are waking up to the real and present danger of anyone, let alone an unstable person, having nuclear codes at his command.
And he is hardly alone in the unstable stakes. Can anyone really find reason to hope when looking at the antics of Kim in North Korea or Netanyahu in Israel?
The recent Nobel Peace Prize came as a bolt out of the blue. Hopefully it will not be an isolated and forgotten moment of sanity in a world with an increasingly desperate need of sanity.
