It's taking place in towns and cities across the world.
At the end of a week where climate change activists bought parts of Exeter to a standstill by "swarming" and blocking roads, students will today march through the city for the same cause.
The #YouthStrike4Climate is part of global movement. On their Facebook event for Exeter, they say they are protesting against: "the government's dangerous lack of action to prevent climate breakdown."
This is the route the students will take through Exeter today.
