What can a stunningly beautiful, dirt-poor, corrupt, tropical-island nation teach us about the battle between China and the West... and about how climate chaos will affect you?

A lot, it turns out. In this bonus episode, Josh is on the ground in Solomon Islands, where leaders from across the Pacific are currently attending the 54th Pacific Islands Forum Meeting. Beneath all the happy-talk about foreign aid is a deeper subtext. The big rich players (i.e. Australia) are trying to bribe their tiny South Pacific neighbours into siding with the West instead of China.

Josh visits a freshwater spring in the jungle with one of Australia's leading hydro-geologists, Sam Buchanan, who's stationed in Solomon Islands to manage its long-term water projects. Sam works for the principal scientific and technical organisation in the Pacific region, The Pacific Community, and is a world-leading expert on water security and climate resilience in small island developing states. He's also one of Josh's oldest friends, who brought to Josh's attention this amazing story in a forgotten tropical battleground.

Josh and Sam drive around Guadalcanal, the country's main island (and the site of the famous WWII battle in which a young naval officer named John F Kennedy made his name), discussing how the country gets its water, how it gets energy, how foreign aid is distributed, how geophysicists are using MRI technology to scan for underground water, and what this all has to do with DOGE, Trump, and subsidence in the Central Valley of California.
