Protestors took to the streets of London today, calling for urgent action to tackle the climate emergency.

Demonstrations took place around the UK and across the world as part of the Global Climate Strike, demanding change from government leaders.

In the capital, children, parents, workers and activists gathered near Parliament, and locally in boroughs including in Islington, Camden, Waltham Forest, and Tower Hamlets.

Jeremy Corbyn was among the speakers to address the crowds in Westminster, calling for a “green industrial revolution”.

The Labour leader thanked protestors for their “determination to combat climate change, protect our environment and our planet”.

Speaking ahead of Labour party conference, he called for investment in green jobs, sustainable agriculture, and rewilding to protect nature.

And he criticised American president Donald Trump for his plans to withdraw from the Paris Agreement, an international plan to keep global temperature rises below 2°C.

He said: “Let’s have no more of this hand holding with Donald Trump.

“Let’s quite simply say that we want every country on board with this, every country fully signed up to this, and going a lot further than that.”

Mayor of London Sadiq Khan said he was “standing in solidarity” with all protestors taking part in the global strike.

Speaking in a video posted on Twitter, he said: “The stark reality is that we can’t do it alone.

“The Government must take real and ambitious climate action to fund a Green New Deal, to insulate our buildings, to decarbonise our transport networks, and to create high-quality, high-skilled green jobs.

“Today’s day of action shows the world demands change and now is the time for Government to step up.”

Liberal Democrat mayoral candidate Siobhan Benita and Green candidate and party co-leader Sian Berry also joined those protesting across the city today.

Today’s protests build of the Fridays for Future school strikes, which have seen pupils around the world leave the classroom on Fridays in protest at the threat to their futures.

The movement began with school girl Greta Thunberg standing outside the Swedish parliament to highlight the threat of climate change.

Her protest gained international attention, and has now made her one of the most recognisable faces of the climate movement.Today’s strike is the first of two major protests this month, with children calling on adults to support them in taking action.

The second will be next Friday, with the strikes designed to put pressure on delegates attending the UN Climate Change Summit in New York next week.
