Thank you all for coming here.
I have some good news and some bad news regarding the climate emergency. I will start with the good news.
The world, as a small number of people have been saying lately, will not end in 11 years.
The bad news, however, is that around the year 2030, if we continue with business as usual, we will likely be in a position where we may pass a number of tipping points. And then we might no longer be able to undo the irreversible climate breakdown.
A lot of people, a lot of politicians, business leaders, journalists, say they don't agree with what we are saying. They say we children are exaggerating, that we are alarmists. To answer this I would like to refer to page 108, chapter 2 in the latest IPCC [Intergovernmental Panel on Climate] report. There you will find all our "opinions" summarized, because there you find a remaining carbon dioxide budget. Right there it says that if we are to have a sixty-seven percent chance of limiting the global temperature rise to below 1.5 degrees, we had on January 1, 2018, 420 gigatons of carbon dioxide left in our CO2 budget. And of course that number is much lower today. We emit about 42 gigatons of CO2 every year.
At current emissions levels, that remaining budget is gone within roughly eight and a half years. These numbers are as real as it gets. Though a great number of scientists suggests that they are too generous, these are the ones that have been accepted by all nations through the IPCC.
And not once, not one single time have I heard any politician, journalist or business leader even mention these numbers. It is almost like you don't even know they exist, as if you haven't even read the latest IPCC reports on which the future of our civilization is depending.
Or maybe you are simply not mature enough to tell it like it is. Because even that burden you leave to us children. We become the bad guys who have to tell people these uncomfortable things, because no one else wants to or dares to. And just for quoting and acting on these numbers, these scientific facts, we receive unimaginable amounts of hate and threats. We are being mocked and lied about by elected officials, members of parliaments, business leaders, journalists. What I really would like to ask all of those who question our so-called "opinions" or think that we are extreme: Do you have a different budget for at least a reasonable chance of staying below the 1.5 degrees of warming limit? Is there another intergovernmental panel on climate change? Is there a secret Paris agreement that we don't know about? One that not [does not include] the aspect of equity? Because these are the numbers that count, this is the current best available science. You can't simply make up your own facts just because you don't like what you hear.
There is no middle ground when it comes to the climate and ecological emergency. Of course you could argue that we should go for a more risky pathway, such as the alternative of 580 gigatons of CO2 from January 1, 2018, which gives us a 50/50 percent chance of limiting the global temperature rise to below 1.5 degrees. That amount of carbon dioxide will run out in about 12 years of current business as usual. But why should we do that, why should we accept taking that risk, leaving the future living conditions for humankind to a 50/50 flip of a coin?
Four hundred twenty gigatons left of CO2 to emit. And now that number is down to less than 360 gigatons. And please note that these figures are global and therefore do not say anything about the aspect of equity, clearly stated throughout the Paris agreement, which is absolutely necessary to make it work on a global scale. That means that richer countries need to get down to zero emissions faster, so the people in poorer parts of the world can heighten their standard of living by building some of the infrastructure that we have already built, such as roads, hospitals, electricity, schools and providing clean drinking water.
And because you have ignored these facts, because you and pretty much all of the media to this very minute, keep ignoring them, people do not know what is going on. If you respect the science, if you understand the science, then this is it. Four hundred twenty gigatons of CO2 left to emit on January 1 to have a sixty-seven percent chance of staying below a 1.5 degrees of global temperature rise, according to the IPCC.
In the Paris agreement we have only signed up for staying below 1.5 to 2 degrees of temperature rise. And that of course gives us a bigger remaining carbon dioxide budget. But the latest IPCC report shows that aiming instead for below 1.5 degrees would significantly reduce the climate impacts, and that would most certainly save countless of human lives.
This is what it's all about, this is all that we are saying. But I will also tell you this: -You cannot solve the crisis without treating it as a crisis, without seeing the full picture. You cannot leave the responsibility to individuals, politicians, the market or other parts of the world to take. This has to include everything and everyone.
Once you realize how painfully small the size of our remaining carbon dioxide budget is, once you realize how fast it is disappearing, once you realize that basically nothing is being done about it and once you realize that almost no one is even aware of the fact that carbon dioxide budgets even exists, then tell me what exactly do you do? And how do we do it without sounding alarmist? That is the question we must ask ourselves, and the people in power.
The science is clear and all we children are doing is communicating and acting on that united science.
Now political leaders in some countries are starting to talk. They are starting to declare climate emergencies and announcing dates for so-called climate neutrality. And declaring a climate emergency is good. But only setting up these vague, distant dates and saying things which give the impression of that things are being done and that action is on the way, will most likely do more harm than good. Because of the changes required are still nowhere in sight. Not in France, not in the EU, nowhere. And I believe that the biggest danger is not our inaction. The real danger is when companies and politicians are making it look like real action is happening, when in fact almost nothing is being done, apart from clever accounting and creative PR.
The climate and ecological emergency is right here, right now. But it has only just begun, it will get worse. Four hundred twenty gigatons of CO2 left to emit on January 1, 2018, to have a 67 percent chance of staying below a 1.5 degrees of global temperature rise. And now that figure is already down to less than 360 gigatons.
At current emissions levels that remaining budget is gone within roughly eight and a half years. In fact, since I started this speech the world has emitted about 800,000 tons of carbon dioxide. And if anyone still has excuses not to listen, not to act, not to care, I ask you once again: Is there another Intergovernmental Panel on Climate Change? Is there a secret Paris agreement that we don't know about? One that does not include the aspect of equity? Do you have a different budget for at least a reasonable chance of staying below 1.5 degrees of global temperature rise?
Some people have chosen not to come here today. Some people have chosen not to listen to us. And that is fine, we are after all just children. You don't have to listen to us, but you do have to listen to the united science, the scientists. And that is all we ask, just unite behind the science!
