Climate change is perhaps the clearest example in contemporary Australian politics of a genuine, evidence-based problem being transformed, through the alchemy of media and tribal politics, into an identity-defining culture war.
On one side: those for whom climate action is a quasi-religious commitment, in which doubt about any particular policy is treated as equivalent to denial of the underlying science, and in which purity of commitment matters more than effectiveness of outcome. On the other side: those for whom climate scepticism has become a tribal marker, a way of signalling that you are not one of the inner-urban progressives, and in which any concession to climate science is experienced as a surrender to the enemy.
Neither position is adequate to the actual challenge. And Australia — a country highly vulnerable to climate impacts and highly dependent on fossil fuel exports — has paid a real price for allowing this debate to be conducted primarily on tribal grounds.
What the Evidence Actually Says
Human-caused climate change is real. The scientific consensus on this point is as strong as scientific consensus gets — not because scientists are conspirators, but because the evidence from multiple independent lines of inquiry all points in the same direction. Anyone who tells you otherwise is either misinformed or misrepresenting the state of knowledge.
The costs of unaddressed climate change for Australia are significant. More frequent and severe droughts, fires, floods, and heatwaves; damage to the Great Barrier Reef; increasing pressure on agricultural production in already-stressed regions. These are not projections from climate activists — they are assessments from the Bureau of Meteorology, CSIRO, the Reserve Bank, and insurance industry actuaries.
The transition to a low-carbon economy also carries real costs, particularly for communities and workers dependent on fossil fuel industries. These costs are also real, also documented, and also deserve serious policy attention rather than dismissal.
What a Sensible Policy Would Do
A genuinely evidence-based climate policy would start with the question: how do we reduce emissions at the lowest possible economic cost and with the greatest possible certainty of outcome? That question leads relatively quickly to a carbon price or carbon market as the most economically efficient instrument — a conclusion reached by economists across the political spectrum for decades.
It would also take transition seriously. Workers in coal mining, gas extraction, and related industries deserve genuine support — retraining, income protection, and investment in the economic diversification of their communities — not slogans about the “green jobs” that will supposedly appear spontaneously to replace the ones lost.
And it would be honest about trade-offs. A country that unilaterally destroys its own export industry without materially affecting global emissions has achieved nothing except domestic economic pain. Global climate policy requires global cooperation, and Australia’s leverage in that cooperation depends on maintaining the economic strength to be a credible partner.
None of this is radical. Most of it is mainstream economics. The reason it hasn’t been implemented is not because it’s technically difficult — it’s because our politics has been captured by a debate that prioritises tribal identity over practical outcomes. That is a choice. We can make a different one.
