Can blog posts be better than journal articles?

By | Climate Change, Environment, Health, History, Language, Media, Politics, Religion, Research | 97 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…

The March for Science

By | ABC, Climate Change, Education, History, Media, Politics, Religion, Research | 119 Comments

I am writing this essay on the day of the March, which will happen in Washington DC and apparently 500 other cities, including several in Australia, where the March is happening as I write. What is it about? There is apparently a ‘war on science’, though who is conducting it is not clear. From its US website you can get this mission statement. The March for Science champions robustly funded and publicly communicated science as a pillar of human freedom and prosperity. We unite as a diverse, nonpartisan group to call for science that upholds the common good and for political leaders…

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…

A final thought on 2016 Australian warming

By | ABC, Climate Change, Environment, History, Media, Politics, Religion, Research | 232 Comments

In an earlier essay this year, I used the useful maps prepared by Professor Ole Humlum of www.climate4you to ponder about how hot it actually was in Australia last year. I did so because of claims that the year was the hottest ever, as it was said to be for the world. When I wrote the piece I did not have access to the summary for the whole year, but I now have it, and it is displayed below. These data are from the Goddard Institute of Space Studies, which is part of NASA, and they show the relative change between…

Another passage to India

By | Books, History, Humour, Language, Music, Religion, Society | 3 Comments

While I have been at least twice to every Asian country save Mongolia and North Korea, South Asia has passed me by (vice versa, more accurately). I’ve not been to Pakistan, Bangladesh or Afghanistan, I visited Sri Lanka only briefly and a long time ago, while India I’ve been to once only. There’s no good reason. I had a very bright Indian doctoral student who has remained a friend through life, my eldest daughter travelled over India on her way home from London (which made her vegetarian for a decade), I think Virat Kohli is a superb batsman, and I have…

In terms of temperature, what sort of a year did we have in Australia?

By | ABC, Climate Change, Environment, History, Media, Politics, Religion, Research | 480 Comments

For the past decade or so, each January has produced a news headline about whether or not this year has been the hottest ever. It seems to be agreed that 2016 was the hottest ever, but with a statistically insignificant increase over 2015, and only a tiny bit above 1998. In 2015, 2016 and 1998 the spike was due to an el Nino, which subsided quickly. As I have argued before, there is no human being who has ever experienced a global average temperature, unless coincidentally, and for a moment or two. What we want to know is what our own environment…

Truthiness and factiness

By | ABC, Climate Change, Education, Environment, History, Media, Politics, Religion, Research | 278 Comments

Both of these terms were coined by an American satirist, Stephen Colbert, more than ten years ago. With respect to ‘truthiness’, he said We’re not talking about truth. ‘We’re talking about something that seems like truth — the truth we want to exist’. He thought that the ‘word police’ would object that ’truthiness’ was not a word, but in fact the next year Merriam-Webster pronounced ‘truthiness’ as its word of the year. I’ll leave ‘factiness’ for a moment. What did Colbert mean by truthiness? In an interview with The Onion he expanded on its meaning in this way: It used…

Is the tide turning?

By | Climate Change, Environment, Media, Other, Politics, Religion, Research | 261 Comments

Even before the election of Donald Trump I had begun to think that there seemed within the body politic to be a move away from the notion that some kind of catastrophic doom faced humanity unless we kept carbon dioxide concentrations to 350 ppm/reduced greenhouse gas emissions/stopped mining coal/all bought electric cars, and the like. Now that President-elect Trump has set out some of what he proposes to do in the ‘climate change’ area, it seems that even in the mainstream media statements are being made that would have been unlikely before that Tuesday in November. What has drawn my…
