  Defusing the population bomb. Can global economies just keep growing forever? Or will we finally reach the ultimate limits of growth – with disastrous consequences for humanity?

  Could climate change really end civilisation? Global warming will cause massive social and political upheaval. But despite wild claims of apocalypse, our civilisation – and our species – are not under threat.

Do our climate targets mean anything at all? Reaching net-zero in 27 years looks near-impossible. It's going to take a hell of a lot more than getting rid of coal-fired power stations.

In denial: Defence’s giant carbon footprint.   In almost every country, armed forces are responsible for massive greenhouse gas pollution. But governments – including Australia’s – do not disclose that, and do not accurately include defence emissions in their carbon-reduction targets.

Survive or perish? Bob Brown on the greatest choice facing humanity. Bob Brown’s Eureka moment came in 1973, when he and a local dairy farmer went chasing thylacines in the Tarkine wilderness of north-west Tasmania.

A new arms race and nuclear Armageddon: UN chief’s grim warning. “Humanity,” said António Guterres in Hiroshima, “is playing with a loaded gun.”

Climate change, rainforest destruction and the next pandemic. Climate change is supercharging the risk that already exists from another form of environmental destruction – uncontrolled agricultural development in tropical rainforests.
