Mirror worlds:  Can digital twins save humanity?

By 2050, much of its land could be lost to high tides.

In response, Tuvalu is creating a digital twin — an online version of its islands, people, and government — to preserve national identity and function beyond land loss.

Using 3D modelling, drone footage, and blockchain tech, Tuvalu is building virtual replicas of its islands and administrative systems — including cultural archives and public services.

These models aren't just visual  — they respond to real-world data like weather and sea levels, helping plan and adapt to environmental change.

For some countries, digital twins offer a glimpse into a possible climate future and help prepare for climate disruption — and keep culture alive in the cloud.

But for Tuvalu, that future  is already reality.

As rising seas swallow land and salt water poisons crops, Tuvaluan leaders don’t need simulations —they only need to look outside.

“As our land disappears, we have no choice but to become the world’s first digital nation.”

“Part of our advocacy and messaging is to try and get people to understand how climate change is really affecting countries like Tuvalu that are at the forefront.”  - Tuvalu Foreign Minister Simon Kofe.

Kofe hopes that contemplating a digital future serves as a  wake-up-call to the rest of the world, allowing them to avoid entering the digital twin altogether.

“Scientists are predicting that our islands could be fully submerged within a matter of decades.  This is a plan for that worst-case scenario.”
