Extinction Rebellion protestors outside Royal Courts of Justice in London. The environmental activist group Extinction Rebellion has carried out protests in five UK cities, marking the start of what it describes as a "summer uprising". Monday's demonstrations - targeting London, Cardiff, Leeds, Bristol and Glasgow - caused disruption to traffic in parts of the cities. The group is calling for greater government action on the climate crisis. Protests in each city are focusing on a different ecological threat - rising sea levels, floods, wildfires, crop failures and extreme weather. The group has installed large boats in each location, branded with the message "Act Now!" ? Evening Standard / eyevine
