Friends,

**Today more people took to the streets calling for climate action than on any other day in history**. **From New York City to Rio, London to Delhi — we were everywhere.**

This is what hope looks like:

On Tuesday, more world leaders will gather in New York to talk about climate action than have ever been assembled before — 125 heads of state. They’ll be gathering with the knowledge that more people than ever are demanding action, not just words, and that their political future is on the line — as well as the future of the planet.

We have a plan to bring that message to the top leadership of the UN inside Tuesday’s summit, with a hand-delivered message to top UN climate negotiators. **If you stand with the hundreds of thousands of people who marched today around the world, you can tell world leaders that we mean business: [act.350.org/letter/ready-for-action/](https://act.350.org/letter/ready-for-action/)**

Today people from the communities where fossil fuels are dug up marched alongside people who live where they are burned. Thousands of workers, the people who stand ready to build a clean, renewable energy system, walked alongside indigenous communities that are already leading with their own climate solutions.

**The ripples of the People’s Climate Mobilization are already spreading.** A people’s summit outlining the path to a just transition away from fossil fuels starts today, and actions targeting corporate polluters in New York are ramping up.

**[With your help those ripples can spread further](https://act.350.org/letter/ready-for-action/), and strengthen — and on Tuesday, hopefully help rock world leaders into action, where they have only offered words before.**

I want you to take a moment to appreciate the importance of what happened today. We are mobilising at the scale that science and justice demand, and it is beautiful in a way we could not have imagined.

Now our work continues — and stronger than ever.

With hope,

Eduardo, Hoda, Mahir, Payal, and Will for the whole 350.org team
