How do you build a lifeboat for an entire nation? In Tuvalu: Losing Paradise, Channel 4 News grapples with the extinction-level threat faced by 25-year-old Grace Malie, for whom 1.5 degrees isn’t just a target, but the difference between life and death for everything that she and her people hold dear. Her Polynesian ancestors navigated the vast Pacific Ocean and settled on nine low-lying islands that have sustained them for upwards of 3,000 years. But today, Tuvalu sits at the epicentre of climatic changes with seas rising one and a half times faster than the rest of the planet. Over the last two years, Channel 4 News UK has been charting a ground-breaking project to work out how to move a nation, its government, culture and people. With just 11,000 inhabitants, if a dignified future cannot be salvaged for them, there is little hope for the billion plus more climate migrants predicted to follow closely behind. Grace’s Tuvalu will likely be the first sovereign nation lost to climate change, but it won’t be the last. This is THE story of our century, told by one of the climate warriors of the future, voyaging across the world to demand that we listen.
