The U.K. Parliament declared a symbolic climate change emergency on Wednesday, backing a call by opposition Labour leader Jeremy Corbyn for "rapid and dramatic action" to protect the environment for generations to come.

The measure was passed as an opposition motion, using a procedure typically ignored by the ruling party, and has no direct consequences for policy.

But it is a nod to an increasing vocal activist movement particularly among young people in Europe, who have staged school strikes and civil disobedience campaigns to demand action.
