Schools' climate change protests
Bristol Cathedral says it stands with Greta Thunberg and the young climate activists, as thousands of people have joined the climate strike action.
The cathedral says it will be open as a refuge for anyone who wants a quiet space away from the crowds.
"The Diocese of Bristol has already declared a climate emergency and the Church of England has already committed all its churches to be carbon neutral by 2030.
"We stand with you."
Bristol has a history of campaigning for sustainability and in the 1970s and 1980s some of the UK's leading environmental charities chose to base themselves here.
The city was European Green Capital in 2015 and the council was one of the first in the UK to declare a climate emergency.
They have pledged to reduce carbon dioxide emissions by 40% by 2020 and 80% by 2050 and recently also declared an ecological emergency.
Many of the founder members of the national activist network Extinction Rebellion are from this part of the world as well as the head offices for Sustrans, City to Sea, the Bristol Community Energy Fund and the Bristol Energy Cooperative.
