Former career mining professional Simon Michaux gives a public lecture in Adelaide describing the onset of 'peak mining' and its various implications for natural resource management. A significant and comprehensive update to the field. Governments will be watching this one and trying to ignore it.
What would Dr Nugget Coombs think of our treatment of the environment and the economy today? Quark applies a retrospectoscope to the problem as she reports on a 1970 Boyer Lecture on environment and economy.
Has the prospect of global temperature rises between two and six degrees centigrade got you down? Don’t worry, for the world might well be in for a cooling trend. The kind that comes after the planet is enveloped in a canopy of ash and debris following a thermo-nuclear war.

Are you like me? Do you hate hot humid summers that never end? Do you toss and turn in the night, soaked in sweat, not finding relief, even in the darkest basement or under the shade of the biggest tree? Don’t worry, for the world might well be in for a cooling trend. The kind that comes after the planet is enveloped in a canopy of ash and debris following a thermo-nuclear war. You see, nuclear winter, the bogeyman you thought had gone into permanent retirement when the Berlin Wall came down and the Soviet empire bit the dust, is still on the menu.
In the following article, originally published in the Winter 2008 issue of The Independent Australian magazine, Dr John O'Connor draws attention to Professor Jared Diamond's book Collapse: How Societies Choose to Fail or Survive and the chapter in it specifically on Australia and its overpopulation woes.
Jared Diamond on Australia's Sustainable Population

Perhaps the single most astonishing, ridiculously contradictory set of public policies we face, is the left hand of government promoting reduced greenhouse emissions, conservation of diminishing freshwater, soil fertility and other declining natural resources, while the right hand promotes rapid population growth through high immigration.
Lampedusa is a tiny Italian island near Malta. It is located 205km from Porto Empedocle in Sicily, 167km from Tunisia and 167km from Libya. It has only 6,000 permanent inhabitants. With the recent failure of Libya to honour a 2004 agreement the Island's resources are being overwhelmed by clandestine immigrants from Africa en-route to Europe.
The immigrants come through Lampedusa, as if through a permanently open door. They do not want to stay too long. Their objective is to go somewhere else, to the rich cities of the north of Italy or of Europe. It is a problem for the European Community, as much as Italy's problem.
