Several thousand people attended a rally in the south-western English city of Bristol to see Thunberg, the teenage activist who has reprimanded governments across the world over climate change.
Known simply as Greta, 17-year-old Thunberg has captured the imagination of many young people with impassioned demands for world leaders to take urgent action.
“I will not be silenced while the world is on fire, will you?
“This emergency is being completely ignored by the politicians, the media and those in power.
“Basically nothing is being done in spite of all the beautiful words.”
“Change the politics not the climate.
“The ocean is rising so are we! And at this point education is pointless,” Thunberg said.
Thunberg rose to prominence when she starting missing lessons two years ago to protest outside the Swedish parliament building.
Since then, she has become the world’s most prominent climate activist.
She has repeatedly upbraided world leaders including U.S. President Donald Trump for ignoring the perils of climate change, though Trump has dismissed what he calls the climate “prophets of doom”.
“Our house is still on fire, Your inaction is fuelling the flames,” Thunberg told the World Economic Forum in Davos in January.
Thunberg has been in Britain since last weekend.
On Tuesday, she visited the University of Oxford, where she met Malala Yousafzai, the 22-year-old Nobel Peace Prize winner and campaigner for girls’ education, who is studying there.
Thunberg called Yousafzai her role model, while Yousafzai said on Twitter: “She’s the only friend I’d skip school for.”
