Climate Change

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…

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…

Mr Abbott as class bad boy

By | Climate Change, Economy, Education, Environment, Health, History, Language, Media, Politics, Society | 155 Comments

Mr Abbott launched a book the other day, and the speech, which you can read here, instantly led to what I now think has been a media beat-up. His short address has become a further indication, for some in the media, and of course for the Labor Party, of the growing destabilising of the Government and the fragility of the Prime Minister. In fact, I think that Mr Abbott’s speech and its content deserve much closer reading. I should probably qualify what follows by saying that I do not agree with some of what Mr Abbott says, but he is absolutely right in reminding…

Exit right, Cory Bernardi

By | ABC, Books, Climate Change, Economy, Environment, History, Humour, Media, Politics, Society | 165 Comments

I have not met Senator Bernardi, but I’ve read  some of his writing. From what I have read in the media and on line, it might surprise some people to learn that in fact he is a published author. His seven books include two for children, the rest being about politics, collections of his own opinion pieces, and a book that did well in the review sections, The Conservative Revolution. Thus far the talk has all been about how his defection from the Liberal Party is another destabilising factor for Prime Minister Malcolm Turnbull. Since Bernardi is unlikely to vote for anything…

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…

Mating, the core of it all

By | Books, Climate Change, Education, History, Politics, Society | 69 Comments

I did a lot of reading over the holiday period, partly because my January  has been consistently hot — not at all with 40 degrees plus — but day after day of around 33 degrees, which gets the ambient heat of our house right up, forces me to put on the air conditioning, and inclines us to sit and read. This essay is the first of a pair, each looking at what seem to me to be the core aspects of human social life, from which everything else hangs. This one is about mating. We human beings rarely have memories extending…

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…
