Tens of thousands of protestors marched peacefully through the center of Glasgow on Saturday, urging politicians and business leaders attending the COP26 climate talks to do more to stem global warming.

More than 100,000 people braved rain and wind to chastise the world’s biggest emitters for not doing enough to cut planet-warming pollution, according to the COP26 Coalition, a U.K.-based network of environmental groups and non-governmental organizations. They said that about 300 demonstrations took place around the world.
