Hundreds of activists formed a human chain outside one of the main plenary halls at the United Nations climate summit on what is traditionally their biggest protest day during the two-week talks. The demonstration in Baku, Azerbaijan will be echoed at sites around the world in a global “day of action” for climate justice that’s become an annual event. Demonstrators held up signs calling for more money to be pledged for climate finance, which involves money for transitioning to clean energy and adapting to climate change. It comes as negotiators at the venue try to hammer out a deal for exactly that — but progress has been slow and observers say the direction of any deal is still unclear.
