Is the climate debate more complex than we’re being told? In this episode of The Focus, Dr John Bruni sits down with Professor Ian Plimer — geologist, author, and one of the most contested voices in Australia’s climate conversation.

Plimer has spent decades arguing that natural geological and planetary processes play a larger role in climate variability than many policymakers acknowledge.
In this extended interview, we explore his arguments, test the evidence, and examine how climate, energy, mining, and geopolitics intersect in ways often overlooked in public debate.

This is not an episode about “right” or “wrong.”

It’s about asking difficult questions, challenging assumptions, and holding space for perspectives that sit outside the mainstream — while keeping the discussion grounded in science, evidence and geopolitics.
