An estimated 12,000 people took to the streets around Westminster to lobby their MPs to call for further, faster action on climate change and environmental protection. With over 300 MPs coming out to meet their constituents we know our voices have been heard.
Perhaps most inspiring were the pupils from primary and secondary schools. Travelling from all over the country to talk to their MPs and have their say on climate change, they're aware we all need to make changes to make a better world.

The Time is Now saw a coming together of people from all faiths and walks of life. The day began with interfaith workshops spanning issues from across the climate and environment spectrum.
Faith leaders from all major religions – including former Archbishop of Canterbury Rowan Williams, Qari Asim MBE, Chair of the Mosques and Imams Advisory Board, Vishvapani, Buddhist teacher and Radio 4 Thought for the Day contributor, Rabbi Jonathan Wittenberg, leader of Masorti Judaism in the UK, and Christine Allen, CAFOD Director – joined together on the steps of St Martin-in-the-Fields.
From St Martin-in-the-Fields we crossed to Trafalgar Square and walked en masse to Whitehall to show we have a shared hope and a common aim. People held banners, took up chants and started the day off with so much energy and enthusiasm!
Kevin Haigh, from the north-east, travelled down to take part in The Time is Now. He is a long-time CAFOD supporter and is no stranger to lobbying his MP. Here are his thoughts on why we need to take urgent climate action:
"It's nearly too late. We need to act, it's got to be now. In 15-20 years it will be too late - I need to think of my grandchildren and what's in front of them.
"Don't hesitate to contact your MP. Ask hard questions and beg them to get something done. We're running out of time."
