In September, heads of state are going to New York City for a historic summit on climate change. With our future on the line, we will take a weekend and use it to bend the course of history.

In New York City there will be an unprecedented climate mobilisation – in size, beauty, and impact. Our demand is a world we know is within our reach: a world with an economy that works for people and the planet. In short, a world safe from the ravages of climate change.

This moment will not be just about New York or the United States. Heads of state from around the world will be there, as will the attention of global media. We know that no single meeting or summit will “solve climate change” and in many ways this moment will not even really be about the summit. We want this moment to be about us – the people who are standing up in our communities, to organise, to build power, to confront the power of fossil fuels, and to shift power to a just, safe, peaceful world.

To do that, we need to act – together.

No single day, just like no single summit will be all it takes. What we are up against is far too large. So as we unite for action this September we are going to try something different as well. We are going to commit ourselves to sustained action and use this to continue strengthening our strategies and work at home.

In Australia, Canada, Europe, New Zealand, and the United States, a big part of what that means will be gearing up for yet another, even bigger fossil fuel divestment mobilisation in the months that follow. In much of Asia and Africa this will mean scaling up the ongoing struggle against coal and other dirty energy and shifting towards distributed, renewable, community power. In the Philippines this will mean mobilising on the 1 year anniversary of Typhoon Haiyan – and hopefully others around the world will join in. In Latin America this will mean fighting fracking as well as preparing to come together in December in the next wave of people’s action as the United Nations Framework on Climate Change meets in Lima. For all of us, this will mean continuing to build a more powerful movement and standing together in solidarity.

Since the time of our first ever global day of climate action in 2009, the world has changed in some dramatic ways. One of the big changes has been just how vibrant and resilient the climate movement itself has become. Now it’s time for us to take it a step further.

Circle it on your calendar: September 20-21 – the People’s Climate Mobilisation and then let’s keep the momentum going!

Eduardo, Hoda, Mahir, Payal, and Will for the whole team
