LONDON - Hundreds of climate change activists camped out in central London on Tuesday during a second day of world protests by the Extinction Rebellion movement to demand more urgent actions to counter global warming. Determined activists glued themselves to the British government’s Department of Transport building as police working to keep streets clear appealed to protesters to move to Trafalgar Square. Cities in Australia, elsewhere in Europe and other parts of the world also had climate change protests for a second day. British Prime Minister Boris Johnson appealed Monday to the protesters to stop blocking London’s streets. He called the activists “uncooperative crusties” who should abandon their “hemp-smelling bivouacs.” Mike Gumn, 33, a National Health Service manager with two children, said he used a day of annual leave so he could attend the demonstration. Gumn, of Bristol, took umbrage at Johnson’s characterization of climate change activists as “hippies.” “I want to make a statement that (the activists) are all different sorts of people from all different walks of life, not just people you would call hippies,” he said. Authorities arrested 319 people at the London protests on Monday. Disruption continued in other major cities. In Brisbane, Australia, protesters chained themselves to intersections in the city center and three people locked themselves onto barrels filled with concrete. A protester hanging from a harness beneath Brisbane’s Story Bridge and brandishing “climate emergency” flags was taken into police custody and charged with unregulated high-risk activity.
