Climate activist Greta Thunberg has given many speeches during her ongoing career. Some of them are memorable. This book, published in 2021, says on the cover that it is updated with new speeches.1

There is a certain repetitiveness about the text of those speeches, read all at once. But that is because Greta Thunberg's message is a very basic one: trust what scientists are telling us about climate change and start treating it as a crisis — not something you can just mouth platitudes about while going on with business as usual.

The speech she made on 27 September 2019 in Montreal, Canada is one of her better ones, in my opinion. Here's an excerpt from that speech (pages 102 through 106):

They say we shouldn't worry, that we should look forward to a bright future. But they forget that if they would have done their job, we wouldn't need to worry. If they had started in time then this crisis would not be the crisis it is today. And we promise: once they start to do their job and take responsibility, we will stop worrying and go basck to school, go back to work. And once again, we are not communicating our opinions or any political views. The cimate and ecological crisis is beyond party politics. We are communicating the current best available science.

"To some people — particularly those who in many ways have created this crisis — that science is far too uncomfortable to address. But we who will have to live with the consequences — and indeed those who are living with the climate and ecological crisis already — don't have a choice. To stay below 1.5°C — and give us a chance to avoid the risk of setting off irreversible chain reactions beyond human control — we must speak the truth and tell it like it is.

In the IPCC's SR15 report that came out last year it says on page 108, chapter 2, that to have a 67 percent chance of staying below 1.5°C global temperature rise — the best odds given by the IPCC — the world had 420 gigatonnes of CO2 left to emit back on January 1, 2018.

Today, that figure is already down to less than 350 gigatonnes.

With today's emissions levels that remaining CO2 budget will be gone within less than 8.5 years.

And please note that these calculations do not include already locked in warming hidden by toxic air pollution, non-linear tipping points, most feedback loops, or the aspect of equity, climate justice.

They are also relying on my generation sucking hundreds of billions of tonnes of CO2 out of the air with technologies that barely exist.

And not once, not one single time, have I heard any politician, journalist or business leader even mention these numbers.

They say let children be children. We agree, let us be children. Do your part, communicate these kinds of numbers instead of leaving that responsibility to us. Then we can go back to 'being children'.

We are not in school today. We are not at work today. Because this is an emergency. And we will not be bystanders.

Some would say we are wasting lesson time; we say we are changing the world. So that when we are older we will be able to say we did everything we could. We will never stop fighting for the living planet and for our future.

We will do everything in our power to stop this crisis from getting worse. Even if that means skipping school or work. Because this is more important.

We have been told so many times that there's no point in doing this, that we won't have an impact anyway, that we can't make a difference. I think we have proven that to be wrong by now.

Through history, the most important changes in society have come from the bottom up, from grassroots. The numbers are still coming in — but it looks like well over 6.6 million people have joined the Week for Future, the strikes on this and last Friday. That is one of the biggest demonstrations in history. The people have spoken and we will continue to speak until our leaders listen and act. We are the change and change is coming.

Le changement arrive — si vous l'aimez ou non!

People say a lot of things about Greta Thunberg. They can say what they like,2 but they cannot change the fact that she is correct: Earth's climate is changing because of human activities; that is a serious problem; and we are not doing enough about it.

1 Greta Thunberg has given a great many speeched. Wikipedia's list mentions one given at COP26 in Glascow, Scotland. It is not in this book. (The Guardian has a video.) I doubt a complete compendium of her speeches has been published anywhere.
2 A lot of what they say is arrant nonsense. For one example, take a look at Rebutting Christopher Caldwell
