Greta Thunberg is set to be joined by 100,000 protestors in Glasgow, Scotland, on Friday 5th November as world leaders gather for the COP26 conference.

Posting on Twitter, the teenage activist said she would join a climate strike march from Kelvingrove Park to George Square to coincide with the world's most important climate change summit. As part of her Fridays for Future marches, it will call for leaders to take meaningful international action on climate change.

Urging others to join, Greta wrote: "On Friday Nov 5 I'll join the climate strike in Glasgow, during #COP26 Climate justice also means social justice and that we leave no one behind. So we invite everyone, especially the workers striking in Glasgow, to join us. See you there!"

Greta, who arrived by train from Amsterdam via London Euston on Saturday along with 150 youth activists, was mobbed by crowds as she made her way through Glasgow's Central Station. Despite reports from the BBC saying Greta wasn't "officially" invited to the summit, the 18-year-old activist appeared in high spirits, giving a thumbs up to surrounding police.

Why was Greta Thunberg not invited to COP26?

Greta Thunberg might be one of the world's most prominent climate activists, but she told BBC's Andrew Marr that she wasn't officially invited. "I don't know. It's very unclear. Not officially. I think that many people might be scared that if they invite too many radical young people, then that might make them look bad," she said.

At first, the 18-year-old said she might not be at COP26, having called for the summit to be postponed until global vaccination rates have risen (there are concerns that developing countries will be excluded if attendees need a vaccine passport).

Despite this, Greta is expected to participate in other climate change rallies during the summit and will speak at a protect taking place on Saturday 6th November hosted by the COP26 Coalition.

What else will Greta Thunberg do at COP29?

As well as her rallies, Greta met with Scotland's First Minister Nicola Sturgeon to discuss what needs to be done. A video from the BBC showed Greta, Nicola and Vanessa Nakate talking about the flooding in Southern Scotland last week.

Nicola told Sky News: "The UK, having the presidency of this COP, has a particular responsibility to corral the leaders, to bring them together, to encourage them to do more than they are currently committed to do.

"There's a big gap on emissions, a big gap on climate finance – so much, much work to be done, and I will do everything I can to push it in the right direction."
