Quick Summary

Australian experts criticize the government’s seventh intergenerational report for downplaying the severe economic impacts of climate change by 2066. The report acknowledges potential sea level rise, reduced worker productivity due to heat, and damage to agriculture and tourism but dismisses the certainty of these effects as “highly uncertain.” Treasury modelling cited in the report suggests a disorderly transition to net zero could cost $2 trillion by 2050, yet experts argue this figure underestimates true economic impacts.

Story summary

Treasurer Jim Chalmers is set to release Australia's seventh Intergenerational Report (IGR) on Monday, forecasting that by 2066, Australia’s population will reach nearly 40 million people with longer life expectancies but lower fertility rates. The IGR outlines significant economic challenges due to an aging population and declining birthrates, emphasizing the critical role of migration in maintaining workforce growth.

Chalmers has hinted at potential further tax cuts for workers as part of his plan to address these long-term issues, suggesting that recent budget improvements have created room for additional relief. However, critics argue that while borrowing less than previously expected is positive, it does not equate to having surplus funds available for such measures without sustainable funding from spending restraint or alternative revenue sources.

The report also highlights the need for policy decisions today to prepare future generations for technological advancements like AI and to address geopolitical uncertainties in a more fragmented world. Prime Minister Anthony Albanese has been pushing for global cooperation on AI regulation during his visit to the United States, where he announced Siobhan McKenna as Australia's next Consul-General in New York, despite concerns about her past ties with News Corp. The announcements come amid efforts by the Australian government to secure a two-year term on the UN Security Council.
