PUPILS in Stroud will once again demand urgent action to tackle climate change in a global school strike this morning.

Students will be meeting at the anti-slavery arch by Archway School at 11am.

The protests are part of YouthStrike4Climate, a youth-driven movement that started after teenage Swedish climate activist Greta Thunberg skipped school and staged sit-ins on Fridays outside the Swedish Parliament.

Supporters hope to build from the momentum of the global climate strikes that took place in September.

"In September, 7.5 million people around the world took to the streets," Thunberg posted on social media yesterday.

"Tomorrow we're doing it again. Everyone's needed. Everyone's welcome."
