Dozens of Extinction Rebellion activists have been arrested as protests take place across the globe. Thirty people were charged with committing offences in Sydney after hundreds blocked a road, while activists surrounded a government building in Wellington, New Zealand. Fifty people were detained in Amsterdam for erecting a tent on a main road. Protests by climate change activists are expected in some 60 cities over the next two weeks. The group is also causing disruption in London, where more than 20 people were arrested on Monday morning. Extinction Rebellion wants governments to take immediate and drastic action to address climate change. "We have tried petitions, lobbying and marches, and now time is running out," Australian activist Jane Morton told the AFP news agency. "We have no choice but to rebel until our government declares a climate and ecological emergency and takes the action that is required to save us." Australia's government has been criticised for its lack of action in tackling climate change but it insists that it is doing its part to reduce global carbon emissions. Australian Home Affairs Minister Peter Dutton said last week that names and photos of Extinction Rebellion protesters should be widely distributed to "shame" them.
