Some concluding thoughts about climate change

By Don Aitkin | Climate Change, Economy, Environment, History, Media, Politics, Religion, Research, Society | 349 Comments

Climate change got me into establishing and maintaining a website, so it’s fitting that I farewell the website (almost) with a comment about this vexed issue. As with defence, nothing much has changed since I first got interested in the issue twenty years ago. Very briefly, I was writing a book about Australia twenty years from now (= then = 2002), and it needed a chapter on ‘the environment’. That took me to global warming, and on the advice of a friend or two, including Ian Castles, the former Australian Statistician, I ploughed through the WGI paper of the Third…

A different defence policy

By Don Aitkin | History, Politics, Research, Society | 43 Comments

I wrote an essay like this for the National Times some fifty years ago. Nothing has changed. If I could find it in my papers I could just run it again. I grew up under the shelter of the Royal Navy. The war brought in a new defender, the United States. Increasingly we bought US weapons apart from submarines. All this was formalised in the ANZUS Treaty of 1951. The essence of ANZUS was that an attack on any of the three parties would be seen by them as an attack on them all. This has led us into a…

The perfect essay on climate change

By Don Aitkin | Books, Climate Change, Economy, Environment, History, Politics, Religion, Research | 444 Comments

Every now and then I come across someone else’s work that is so good I want everyone to read it. This essay, by Richard Lindzen and William Happer, is one such. They are supremely eminent scientists, and their current status is given at the end. Yes, they don’t give references, but then neither do most alarmist speakers, like Steffen, Karoly, Mann and so on. They are speaking from a position of intellectual eminence. Like a few others who are outspoken in their sceptical cause, they are retired. No deans are complaining to the university president about these two. So read…

Voting and talking

By Don Aitkin | Climate Change, Environment, Humour, Media, Politics, Research | 141 Comments

The Canadian humourist Rick Mercer has had a series called ‘Talking to Americans’, and in one interview he asks a group of women what they think about the Russian proposal to bomb Chechnya and Saskatchewan. ‘Should they bomb both, or only one?’ There is a pause and then one of the women says, ‘They should bomb both.’ The others then agreed. Now his program is designed to make Canadians laugh, in this case at the sheer ignorance of those below the border. There’s a moral in it as well. People will feel that they ought to have an answer, especially…

The best job I ever had…

By Don Aitkin | Books, Economy, History, Politics, Research, Society | 14 Comments

We were sitting around the dining table, dinner over, really, but still chatting. I threw into the discussion a theme I had been talking about with my driving son on a recent Saturday. My companions are used to me doing this sort of thing. ‘What’s the best job you ever had?’ They looked at each other. One is a retired graphic artist, another is a retired gas fitter, a third is a former Treasury guy, and the fifth is a former Army officer, and he spoke first. He’d only really had one job, in the army, and he’d enjoyed it, rising…

Back to energy, again

By Don Aitkin | Climate Change, Economy, Environment, Politics, Research, Society | 387 Comments

Driving in the bush with my son on Saturday I saw some gigantic wind turbines on top of a small range, and he told me there was a line of them stretching up to Crookwell, quite a way away. That got us talking about the fantasy of wind power, while later the talk took me to another excellent Judy Curry piece, the origin of which I have begun to read. Since it is nearly 350 pp long I will give readers bits of the Extensive Summary instead. Written by two members of the European Parliament, Katinka Brouwer and Dr Lucas Bergkamp,…

The gentle art of blaming

By Don Aitkin | Climate Change, Environment, Health, Politics, Research | 196 Comments

I rely on Judith Curry of Climate Etc to alert me to useful and provocative essays, articles and books, and she recently wrote a new essay herself, which you can read here. I think that the core element of her essay is the proposition that blaming gets in the way of doing anything sensible about whatever the problem is thought to be. Or, putting it another way, that the goal of the blamers is the immediate punishment of the offenders, not searching for a solution to the imagined problem. She uses material from the pandemic to try to find what…

An important essay by Richard Lindzen

By Don Aitkin | Books, Climate Change, Economy, Environment, History, Media, Politics, Religion, Research | 168 Comments

I am an admirer of Richard Lindzen, an American physicist whose field is the dynamics of the atmosphere-ocean circulation. In this area he is probably without peer, and it gives him a strong position from which to talk about climate change. He is the most prominent critic of the orthodox, IPCCC view of global warming. He recently gave a speech in London for the Global Warming Policy Foundation. It is too long to simply republish here, but what I have done is to edit it down by about two thirds. He started his lecture with a quote from a famous…

Two new reports on climate change

By Don Aitkin | ABC, Books, Climate Change, Environment, History, Media, Politics, Religion, Research, Society | 78 Comments

Two reports bearing on climate change have been published in the last few days. The first is from the Inter-Governmental Panel on Climate Change (IPCC), and is full of forebodings about the future of the planet. This one is a Special Report on the implications of global warming above 1.5 degrees C. There are more of these special reports to come. The basic point or take-home message seems to be that limiting warming to 1.5 C is better for everyone than allowing warming to grow to 2.0C. No matter that both the 1.5C and 2.0C ‘boundaries’ seem to have been pulled…

The ‘Great Debate’ on Climate Science

By Don Aitkin | Books, Climate Change, Environment, History, Media, Politics, Religion, Research | 256 Comments

Some time ago Anthony Watts opened his website to what purported to be a ‘great debate’ on climate science, between William Happer, emeritus professor of physics at Princeton and very recently an adviser to President Trump (Professor Happer and I have corresponded from time to time), and David Karoly, a professor at Melbourne University who has been involved in a number of IPCC reports. I had a particular interest in this debate, because I had debated Professor Karoly myself, some years ago. Apart from saying that there was a lot in what I said that he would agree with, Professor…
