Have we entered what Earth scientists call a “termination event,” and what can we do to avoid the worst outcomes? How can we look beyond GDP and develop new metrics that balance growth with human flourishing and environmental well-being? How can the 15-minute city model revolutionize urban living, enhance health, and reduce our carbon footprint?

The goal with Climate Impulse is to revolutionize aviation and show that we can decarbonize aviation. We can make it more efficient. Of course, it's not yet a jumbo jet with hydrogen. It's a two-seater airplane. But I want to make the ultimate flight to shake a little bit the certitudes of the people. If we go around the world nonstop with two people on board, this project can become like a flagship of climate action.

We're really starting to witness serious climate extremes that can no longer be ignored. And the IPCC, one of our key conclusions to that report was that effectively the human fingerprint on the climate system is now undeniable. It is now an established fact that we have warmed every single continent, every ocean basin on the planet. And again, that's a pretty serious thing to contemplate that human activity from the burning of fossil fuels and the clearing of land has led to this energy imbalance in the earth system, which is leading to a rapidly shifting climate.

So shooting for one planet just means you would be totally dominant, and leave no space for other species. Ecologists say to maintain 85% of preindustrial biodiversity, it would take about at least half the planet left on its own. That would mean getting to half-planet. And now we use at least 1.75. I say at least because our assessments with about 15,000 data points per country in a year are based on UN statistics, and their demand side is probably an underestimate because not all demands are included. And also on the supply side or the regeneration side, the UN is very production oriented, so it's the FAO numbers, for example, look at agricultural production, and the depletion side or the destruction side is not factored in adequately. So that's why it's an underestimate. And still, it shows we use about 1.75 Earths, and that's more than three times half an Earth. So that's kind of the difference. But we also know overshoot will end one way or another. The question is do we choose to end it? Do we choose it by design, or do we let nature take the lead and end overshoot by disaster? So it's really ending overshoot by design or disaster. That's the big choice we need to make.

Director of the George Mason University Center for Climate Change Communication
Humanity needs to do three things if it wants to continue to flourish, and it will. The three things that humanity needs to do are decarbonize the global economy, drawdown, capture, harvest much of that heat-trapping pollution that we've already pumped into the atmosphere over the past hundred years because as long as it's up in our atmosphere, we're going to have continued warming. And the third thing that humanity needs to do is become more resilient to the impacts of climate change, which unfortunately will continue for the next several generations at least, even as we succeed in decarbonizing the global economy and harvesting that heat-trapping pollution from the atmosphere.
So these are the three things that have to happen. These three things will happen. The open question is how rapidly will they happen? Any business that can play a vital role in making any one or two or all three of those things happen, those are businesses that are going to flourish going forward. And any business that's sitting on the side and not contributing to one of those three areas, I really think they will become increasingly irrelevant, if not completely antiquated and increasingly understood to be harmful.

I would like them to know just how powerful they are, that they have the power to shape the world. At some point, I realized that the world is produced. The world is designed and produced, and since we designed and produced it, we can redesign it. And you can play a part in designing it. You can play a part in that production. It doesn't have to happen to you. And I think, for too many people, too much power and too much control is concentrated in too few hands. People need to have the power to control and design their own life.

Nobel Prize-winning Climate Scientist · Lead Author of IPCC Assessment Reports
Author of The Changing Flow of Energy Through the Climate System
This is an intergenerational problem. The response to climate change relates very much to value systems. And one of the questions people ask, or should ask is: How much do you value the future generations? How much do you value the world that you're leaving your children and your grandchildren? And what kind of a climate you're leaving them with? And some people don't care, and some people don't have children. And they say, "Eh, it's not an issue for me. It's not one of my values." And so this is part of the problem, but if you're thinking about peoples as a whole, all of the community that you're leaving behind, this is a collective problem.

So this is why I prefer to speak with a really down to earth language. So maybe the people who love nature are going to say, “Oh, Bertrand Piccard, now he is too down to earth. He's speaking about profitable solutions. He's speaking to the industries that are polluting,” but we have to speak to the industries that are polluting and bring them profitable solutions, otherwise the world will never change, or humankind will never change. And don't forget one thing, what we are damaging is not the beauty of nature. What is being damaged is the quality of life of human beings on Earth because we can still have beautiful things to see, but if we have climate change, if we have tropical disease in Europe, if we have heat waves, floods, droughts, millions of climate refugees, life will be miserable, even if nature is still beautiful.

Looking into the future, as a scientist, what I've learned how to do is hold multiple futures in my head at the same time because we just don't know. We don't know what the future holds. We need to fight for the futures that we want, and against the futures that we don't want. All I can really say is that it's up to us. It's up to us to fight and advocate for the future we want, and what does that look like, and how do we get there?

Drinking Water Made from Sunlight and Air
Water insecurity and water scarcity is affecting all people in almost every part of the world. At this point, by 2025, we expect 1.8 billion people to suffer from water scarcity, which means they have no access to clean, safe drinking water within a 30-minute walk of their home. You fast forward to 2050, we expect 6 billion people will have water scarcity. So the rate at which this problem is increasing is far greater than the current infrastructure that has supported water for humans. And that's where innovation and rapid deployment of technology at scale is really essential. And that's what we're in the business to do.

It seems irresponsible to me to downplay the possible consequences of climate change. It seems irresponsible to assume that we're going to fix it. And so I think it's absolutely a responsibility for the people who are talking about it and thinking about it, to look at the worst-case scenario and to look at the current trajectories, absent technologies for carbon scrubbers, to look at where we're actually headed, the worst-case scenarios, and address that and bring that to each other and to our children and to our students. When you really look at the situation, it's scary and terrifying, and it upends everything that we've been told to make sense of life.
