Today, we are out on the streets again, in huge numbers, in 110 countries, at over 1350 events, demanding that governments immediately provide a safe pathway to stay below 1.5 degrees of warming. We spent weeks and months preparing this day. We spent uncountable hours organizing and mobilizing when we could have just hung out with our friends or studied for school.

We, children and students, don’t feel like we have a choice:  It’s been years of talking, countless negotiations, empty deals on climate change, fossil fuel companies being given free rides to drill beneath our soils and burn away our futures for their profit. Politicians have known about climate change for decades. They have willingly handed over their responsibility for our future to profiteers whose search for quick cash threatens our very existence.

We have learned that if we don’t start acting for our future, nobody else will make the first move. We are the ones we’ve been waiting for.

Once again our voices are being heard on the streets, but it is not just up to us.

We feel a lot of adults haven’t quite understood that we young people won’t hold off the climate crisis ourselves. Sorry, if this is inconvenient for you. But this is not a single-generation job. It’s humanity’s job. We young people can contribute to a larger fight and that can make a huge difference.

So this is our invitation. Starting on Friday 20th September we will kick start a week of climate action with a worldwide strike for the climate.  We’re asking you to step up alongside us. There are many different plans underway in different parts of the world for adults to join together and step up and out of your comfort zone for our climate. Let’s all join together;  with your neighbours, co-workers, friends, family and go out on to the streets to make your voices heard and make this a turning point in our history.

This is about crossing lines – it’s about rebelling wherever one can rebel. It’s not about saying “Yeah, what the kids do is great, if I was young I would have totally joined in.“ It just doesn’t help, but everyone can and must actually help.

During the French revolution mothers flooded the streets for their children. Today we children are fighting for ourselves, but so many of our parents are busy discussing whether our grades are good, or a new diet or what happened in the Game of Thrones finale– whilst the planet burns.

This moment has to happen. Last year’s UN Intergovernmental Panel on Climate Change’s special report on global warming was clear about the unprecedented dangers of going beyond 1.5C of global warming. Emissions must drop rapidly – so that by the time we will be in our mid- and late-20s we are living in a completely transformed world.

But to change everything, we need everyone. It is time for all of us to unleash mass resistance – we have shown that collective action does work. We need to escalate the pressure to make sure that change happens, and we must escalate together.

So this is our chance – join us for the climate strikes and actions this September. People have risen up before to demand action and make change,  if we do so in numbers we have a chance. If we care we must do more than say we do. We must act.

This won’t be the last day we need to take to the streets, but it will be a new beginning. We’re counting on you.
