Trivia, insights & behind the scenes
This is Attenborough's first feature-length ocean documentary since 2001's Blue Planet—24 years of worsening data, 24 years of him waiting for us to catch up.
The 'climate observatory' sequence uses military-grade satellite tech previously classified for tracking submarines—now repurposed to watch ice sheets weep.
