Here in Glasgow, there's something you can't miss about the people who've come from all over the world to be part of the UN Climate Summit.

And I'm not talking about the negotiators, the politicians, the people whose job it is to be here.

I'm talking about the thousands of folks who filled the streets chanting, whose planet our planet.

Many of them are from the same generation as 23-year-old Brianna Frouin, one of the young activists I met here this week.

I was telling someone earlier this week, like, they were asking, how do you know you live with the climate crisis?

And they said, well, I can record the smell of mud.

The smell of mud in her home country, Samoa.

I don't know if you've ever been like a storm or a flood, but when the flood drains back into the ocean, it leaves piles and piles of mud.

And so I scooped mud out of my house.

Brianna is part of a group called Pacific Climate Warriors.

They represent small island nations, some of the country's most vulnerable to a warming planet.

She opened the first day of the COP26 summit here in Glasgow, speaking to leaders from all over the world.

Pacific youth have rallied behind the cry.

We are not drowning. We are fighting.

This is our warrior cry to the world. We are not drowning. We are fighting.

It's a fight young people are waging from Samoa to Uganda. They're 24-year-old activists Vanessa Nakate told me the problems include extreme drought, flooding and landslides.

So with the rising global temperatures, it means that there's lots of people's funds, drying of people's crops, destruction of people's houses.

In Glasgow this week, I heard all kinds of stories like this.

Young activists from around the world say climate change is already transforming their countries.

And to Brianna through an of Samoa, it matters how we tell that story.

A lot of people think my role here at COP is to come and cry.

Like I owe them my trauma when I don't owe you my trauma.
