This post was prompted by an attempt by Scott Morrison to justify the export of Australian coal, in the face of criticisms to the effect that it contributed to climate change.

The first of the skeptical viewpoints mentioned in the Prelude denied that there was such a thing as climate change – I referred to this as NCS. I said that this was not on the face of it, a defensible position, which suggests that we should perhaps just dismiss it straight away and move on to address less implausible views. However, it is worth seeing what someone who adopts NCS is committed to and how her position could be defended. What she is committed to depends on precisely that she is...

Discussions of climate change distinguish climate from weather, usually early on, and usually without much analysis. Thus weather is what we are aware of locally, day to day, what we experience: hot wet, cold dry, sunny cloudy, windy calm, frost snow ice, and so on. Weather is tangible and perceptible, but climate is not, not directly at any rate. Climate, or the climate, is what the weather is like on the whole, or in general. Since the weather changes with the seasons, unless one lives on the...

This post is intended to give a simple, non-technical explanation of the greenhouse effect. The next post will examine some of the technical details.

On August 6 1945 over 10,000 people were killed in less that a second in the city of Hiroshima in Japan. Many were vaporised, literally obliterated from the face of the Earth with no trace of them left, by the ‘heat pulse’ of an atomic bomb dubbed Little Boy. Nuclear weapons give out heat radiation when detonated which travels at the speed of light, which is why people died so quickly. But this is only the first of three ways in which nuclear weapons kill. Those who were far enough away...

I have not blogged since the change of Prime Minister in this country, because I have not felt the same degree of anger, frustration and disgust since Abbott left office. Indeed, Turnbull’s positive approach is most welcome after the fear-mongering of his predecessor; and no one likes a whinger! But now Abbott is to the fore again - demonstrating by his remarks about Western culture and values that among the many things he is not we should include being an historian – and has said he will...

Our Prime Minister commented on the death of the poor little Syrian boy who was washed up on a beach in Turkey, like so much flotsam, certainly a very disturbing image. His comment was that if the local authorities, in Turkey and elsewhere, were stricter about turning back the boats, about preventing boats landing, then as has apparently happened here in the land of Oz, refugees, economic migrants and others would not set out in the first place, and hence not be at peril upon the sea.

The recent North Korean election recorded a vote of 99.7% in favour of Kim Jong-Un’s party. This is reminiscent of the votes in favour of Stalin and other leaders of the Soviet Union, and in Nazi Germany. The results, one supposes, could not have been 100%, as there must have been people who were too ill to vote. Of course, there was only one party to vote for in each case. In a democracy, on the other hand, in a real democracy, there are real alternatives for the group who will control the...
