If health ministers want to keep people out of here they should be supporting - not opposing - action on climate change.
Dan Cox
The ACCC has been vigilant about following up the 45 or so carbon price gouging complaints it gets each day. But who can stop the politicians? Their relentless carbon price scare campaigns seek to frighten…
The government should have been addressing electricity arrangements for the last four years.
Laurent LaSalle

Global land-surface temperatures are up, but it’s not really news.
Stuart Dowell
The Berkeley Earth Surface Temperature (BEST) study recently found that global land-surface temperatures have increased by about 1°C since the 1950s — and 1.5°C since the mid-18th century. These results…
We know next to nothing about Earth ecology.

The landing of the explorer Curiosity on Mars is a fantastic affirmation of the extraordinary technical capacities of humans. A series of remote, high risk choreographed moves saw a small mobile laboratory…
Time to get our eyes back on the prize: the pragmatic, results-focused, multi-sector research effort of recent decades has stalled.
Welcome to Part Two of Professor Andrew Campbell’s special report on the troubling plight of irrigation research and development in Australia. In part one, Professor Campbell argued that despite an unprecedented…
The changes to the landscape in the Upper Hunter region of NSW severely distressed the people who lived there, a feeling not previously captured in the English language.
Glenn Albrecht
The built and natural environments are now changing so rapidly that our language and conceptual frameworks have to work overtime just to keep up. Under the intertwined impacts of global development, rising…
Tuna fishers agree that too many tuna are caught. But there is no good system to decide who should catch less.
Justin Woolford
The world catches too many tuna. Thanks to our high levels of fishing, some tuna species are under threat. Everyone involved in the fishing industry agrees that fishing effort needs to be reduced. But…
Dingo: when they come to rely on humans for food and water, not killing them can be naive.

The sad reality of human-dingo relations is that blood will be shed, as Brad Purcell recently reminded us in these pages with his article about non-violent co-existence, The Australian Dingo: to be respected…
While Australia fears either an environment or economic doomsday, other countries get on with making a cleaner future.

I sometimes wonder what planet this country of ours is on. The environmental debate we are having seems to be in a parallel universe to the rest of the world. Having spent the last four years running one…
