What should former PMs do?

By | Economy, Education, Environment, History, Media, Politics, Society | 44 Comments

At a recent lunch I got into a discussion about the current tensions within the Liberal Party, and more particularly the extent to which they were due to what a friend called the ’irresponsible’ behaviour of Mr Abbott. I had written about Mr Abbott’s situation before, and offered some of that comment at the lunch. My friend would have none of it. Mr Abbott should have left Parliament at the first opportunity, and if he stayed, should have maintained a dignified silence. My view, set out in the conclusion to the essay linked above, is that, ‘He ought to be allowed…

Doing things properly

By | Climate Change, Environment, History, Media, Politics, Religion, Research, Society | 156 Comments

For some time I have wanted to write a piece on the virtue of doing certain things properly, and the final stimulus came on the occasion of a bus trip to Lightning Ridge, which was great fun, educational and most enjoyable. In the bathroom of a certain motel I saw this little sign. Dear Guest, In the course of a year we wash thousands of towels, and doing so uses thousands and thousands of litres of water and tons of detergents that can be harmful to the environment. If you care about the environment as we do, you may wish…

Would Red and Blue Teams be any use to us?

By | Climate Change, Environment, History, Politics, Religion, Research | 154 Comments

For those who don’t know the reference, a Red team is a team whose aim is to go past the defences of the Blue team. More generally, the terms have to do with testing more or less settled policies or positions mostly in defence, but increasingly in information technology, and the new target, cyber-security. There have been suggestions in the past that the model be used in the area of climate science, or more sensibly, climate policy. A pale equivalent in Australia is the use of ‘The Case for Yes’ and ‘The Case for No’ statements in our Constitutional referendums….

Finkel’s Cave

By | Climate Change, Economy, Environment, History, Media, Politics, Religion, Society | 227 Comments

There is an embarrassment of subjects to write about at the end of the week. I had my eyes on the UK General Election, if only because in 1964, now 53 years ago, I worked as a behind-the-scenes analyst on the BBC’s election night coverage, and then became part of the Australian election night coverage for the next nearly twenty years. It is too early to say too much about the outcome, other than to me it seemed a bit of a re-run of the Brexit referendum. There will have been much more than this, of course, especially with respect…

The Alternative and the Real Trump

By | ABC, Climate Change, Economy, Environment, Health, Language, Media, Politics, Religion, Society | 57 Comments

When an elected political leader get into office, the media wait to see if he fulfils any of his campaign promises, and will often needle him or her about an  apparent slowness to do so. With President Trump it is rather the office. He said that if elected he would withdraw the US from the Paris Agreement on climate change, and he has now done so. Instead of saying,’Well, he’s done what he said he would do’, there seems to be a chorus of incomprehension. ‘But surely you only said those things to get elected’ seems to be one theme. ‘How…

Can blog posts be better than journal articles?

By | Climate Change, Environment, Health, History, Language, Media, Politics, Religion, Research | 98 Comments

The Dutch experimental psychologist Daniel Lakens asked this question on his website, and I thought it was worth distilling for mine, since I have had a lot to do with journals and more recently with websites. There has been a deal of discussion recently about the lack of effective replication in both the medical area and others, so the rules about publication are worth thinking about. Before the ‘peer review’ cheer squad starts to chant, I should tell you that Lakens’s goal is to improve the quality of journal articles, not to replace articles with blog posts. He offers five reasons…

The Social Cost of Carbon

By | Climate Change, Environment, History, Language, Media, Politics, Religion, Research | 51 Comments

I was going to write about Earth Hour once more, and for the last time, when I realised that it seemed to have passed its use-by date, for it seemed to have been almost unnoticed. There was no sign of it in Hobart, where I was on the hallowed night, and I couldn’t find out much about its effects in Canberra, where I have been for past Earth Hours. Earth Day passed too, without much fuss. So I have gone on to a subject I have been playing with for some years now, which is caught up in the phrase, ‘the Social…

Gary Banks nails it

By | Climate Change, Economy, Education, Environment, Media, Politics, Society | 59 Comments

For years now I have puzzled at the whole mess of our energy policy. People keep telling us that soon (or now) solar-panelled electricity, or wind, or something, will be cheaper than coal, so we should be transferring, at once. Such oracles never tell us about the hidden subsidies that would make this really true, if it were apparently true. I’ve given up responding. It is plain to me that wind and solar cannot power an electricity grid without abundant base-level fossil-fuel energy. Well, along comes Gary Banks to tell it as it is. For those who don’t know of…

What is it that worries me about what the BoM and CSIRO tell us about climate change?

By | ABC, Climate Change, Environment, History, Media, Politics, Religion, Research | 262 Comments

Commenter Chris asked me, in a comment at my last essay, what are your concerns over BoM reporting or data use? I had intended to write about something else, but it seemed sensible to deal with this issue at once. I have written about the Bureau before (here, for example, and here), but to this direct question there is a straightforward reply. I’ll deal first with the more general issue of BoM (Bureau of Meteorology) reporting, and note first that it is directly linked, as anyone who reads the website will see, with CSIRO’s biennnial reports on the State of Climate. So my response to Chris covers both…
