Why Life in the 21st Century Will Be Nasty, Brutish, and Short

While some global whiners are predicting death, disease and reckless fish, an ominous array of other forces are gathering. The time of plenty, peace and abundance could be coming to an end. I’ve finally had a chance to look at David Archibald’s hot new book, and it’s a book that needs to be discussed. It’s the debate we ought to be having. (I’ll be referring to it again on this blog).

In the West we have rarely had it so good: since World War II things have been relatively peaceful; the sun reached a once-in-8000-year global maximum, keeping us warm; the big easy oil fields were tapped, gifting  us the cheapest energy in human history; and the most obvious gains in agriculture meant food supply increased even faster than populations grew.  David Archibald paints a provocative argument of a world where a cooling sun means grain supply can’t keep pace with demand, oil production starts to slide and forces of unrest in the mid East collapse to chaos while those in the far East rise ascendant.

David Archibald writes:

Who are those four horsemen?  A severe, solar-driven cooling is one.  Over the next twenty to thirty years, we are [...]

Australia’s Invisible Energy Trade: better than most and getting even better

Australia  (orange line second from the bottom) has a lower energy intensity of use than many countries (see below for more information). On this graph. Japan is the lowest. The world average is the dark purple line. China is so high it is off the scale.

It’s part of the spin game  that almost every statistic is spun-into-oblivion, and here, thanks to Mike Wilson, is the analysis of why “per capita” statistics are meaningless.

Ross Garnaut (and dozens of others) claim Australia has a high emissions intensity of energy use. Yet Mike Wilson shows below that  Australia’s energy intensity is not just declining, it’s below the world average, and below Canada, South Africa, China and the US.

The Garnaut Review:

“Relative to other OECD countries, Australia’s high emissions are mainly the result of the high emissions intensity of energy use, rather than the high energy intensity of the economy or exceptionally high per capita income. Transport emissions are not dissimilar to those of other developed countries. Australia’s per capita agricultural emissions are among the highest in the world, especially because of the large numbers of sheep and cattle.

The high emissions intensity of energy [...]
