Today, the island nation that's disappearing.

The two-valued people are very beautiful and I have a very beautiful culture. They're very welcoming, very hospitable.

From the moment we arrived, there was lots of singing, beautiful harmonies, coming out of church buildings.

I think that's the beautiful thing that I experience is despite this really serious threat that they are facing as a nation.

Everyone was very positive and everyone smiled.

Kalalina Fainu is a reporter who lives in Papua New Guinea.

With her husband Chris, a sound recordist and their baby, she made the journey recently to Tuvalu, a Pacific island nation that's just north of Fiji.

They went to capture the sounds of a country that's being lost to climate change and to talk to people who are losing their homeland.

When I was growing up, we would go to the beach, go out, snorkeling, diving, really pristine beaches and lots of green vegetation.

So that pristine environment has eroded all the time.

The nine atolls that make up Tuvalu are disappearing under the rising sea.

Climate scientists project that if the world's carbon emissions continue at the same rate they're at now,

much of this country will be uninhabitable within 30 years. By the end of this century, it could have gone altogether.

If predictions are realised, that's the end of Tuvalu, the whole country and the identity, the cultural heritage, would be lost, completely wiped out from the face of the earth.

Already, people on Tuvalu are having to deal with the extreme consequences of the climate crisis.

Pacific leaders have been warning about this for decades and people on Tuvalu are still fighting to protect their country.

Now, the government has decided to take a radical approach. If they can't save the nation, they say they'll archive it.

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

Our land, our ocean, our culture are the most precious assets of our people.

And to keep them safe from harm, no matter what happens in the physical world, will move them to the cloud.

Islands like this one won't...
