Climate activists worldwide are raising the stakes, with many turning to civil disobedience to make their voices heard. Actions in recent months have ranged from chaining themselves to coal conveyor belts in Sydney, to forming port blockades in the Netherlands, to scaling smokestacks in the United Kingdom.
The rise in activism reflects growing frustration against the continued, and expanding, use of coal as a source of energy. The fuel, while affordable, is directly linked to climate change and air pollution.
