Australia

Burning questions: a more fire-prone world adds Australia through the 2019-20 Black Summer fires. The source uses those fires as Extreme Wildfire and Wildfire Climate Feedback examples, saying smoke may have helped maintain a multi-year La Nina state and fertilized Pacific waters enough to produce a large phytoplankton bloom.

OpenAI model unintentionally hacks another company’s system extends Australia’s wiki role from a policy model into an effectiveness warning. Will Oremus says research he has seen from Australia suggests children under 16 found ways to remain on social media through fake accounts, other login methods, or VPNs, qualifying Social Media Age Bans and Online Age Verification.

Australia is the first country case in Our mission: Find the world’s best economic ideas (Summer School World Tour), where Planet Money uses it to explain Water Market Design. The episode presents Australian water markets as among the world’s most advanced systems for buying and selling water rights, especially in drought-prone agricultural regions.

The episode also uses Australia as a democratic-institution contrast. Justin Wolfers points to Saturday elections and community voting rituals as examples of civic design that can make participation easier and more cohesive.

How to get what Greenland has, with permission adds Australia as a more plausible near-term partner in rare-earth supply or processing than Greenland.

Would banning teens from social media violate their First Amendment rights? adds Australia as the policy model cited for California AB 1709, California’s proposed under-16 social-media ban. The episode does not analyze the Australian policy in detail, but it uses the comparison to show how youth social-media restrictions can travel across jurisdictions before encountering U.S. Youth Online Speech Rights constraints.

How online age-gating laws went mainstream this year adds Australia to the broader Online Age Verification trend. The episode says Australian rules are part of the same international movement toward age assurance, making Australia an Age Verification Patchwork reference beyond the narrower social-media-ban comparison.
