What lessons are already available to us as we tackle climate change? For Session 2 of TED Countdown Summit 2023, science, solutions and the role of industry in stemming the threat of the climate emergency took center stage.

The event: Talks from Session 2 of TED Countdown Summit 2023, hosted by TED’s Lindsay Levin and David Lammy, Member of Parliament for Tottenham, England and Shadow Foreign Secretary

When and where: Wednesday, July 12, 2023, at the Fillmore Detroit in Detroit, Michigan

Speakers: Jonathan Foley, Emma Nehrenheim, Cedrik Neike, Susan Lozier, Morten Bo Christiansen, Bo Cerup-Simonsen, Mike Duggan, Laprisha Berry Daniels

To solve climate change, the International Monetary Fund estimates that the global community needs to invest between three and six trillion dollars annually in climate solutions. Where should that money go and which projects should we fund? Jonathan Foley, executive director of Project Drawdown, uses a science-based framework to outline a plan for investing with maximum impact. First, we need to prioritize immediate actions with cumulative benefits, like stopping deforestation and cutting methane leaks. Next, we should focus our spending on cutting carbon emissions now over investing in distant high-tech solutions. Third, we must prioritize geographical hotspots with an outsized effect on climate change, like the Amazon rainforest or high-emission factories. And finally, we should invest in solutions that benefit people’s well-being, promote food security and increase access to clean water and sanitation.

Batteries will be fundamental to powering a sustainable world — but only if we don’t repeat the same mistakes of past industrialization, says battery recycler Emma Nehrenheim. She outlines the environmentally intensive impact of battery production — particularly from the extraction of minerals for lithium-ion batteries, which provide energy for electric vehicles and other key aspects of life — and proposes a shift towards a circular battery economy that uses and reuses already existing materials, vastly reducing the industry’s carbon footprint and need for mineral extraction.

We are running out of time to save our planet from climate change — and the metaverse can help. Using virtual tools like AI to cheat time in the real world, Cedrik Neike explains how “digital twin technology” (think simulated giga factories that are one-for-one digital copies of real ones) can help solve real-world problems more efficiently by providing a digital space to test solutions, without pollution. Using the example of virtually ideating the production of safer and faster-charging batteries and then bringing those learnings to the physical world, Neike points to the potential of industrial metaverses to revolutionize industries and redesign entire cities — from transportation, agriculture and housing — addressing massive challenges and avoiding the creation of excess waste at the same time.

Oceanographer Susan Lozier dives into the importance of the ocean’s natural circulation, which overturns water in a way that naturally captures carbon and regulates global temperatures. She shares the incredible research being done internationally to track changes in this overturn, as warming global temperatures could slow the circulation, lessen carbon uptake and increase the rate of climate-related disasters. While a collapse in this age-old system isn’t likely until 2100, Lozier warns of the dangers faced by future generations if we don’t change course now, calling for climate action to lower temperatures within the next 10 years.

SVP of A.P. Moller – Maersk Morten Bo Christiansen and TED’s Lindsay Levin speak at Session 2 of TED Countdown Summit on July 12, 2023, at the Fillmore Detroit in Detroit, Michigan. (Photo: Nick Hagen / TED)

As leader of the decarbonization team for A.P. Moller – Maersk, Morten Bo Christiansen is drawing an organizational roadmap to net zero that could help transform the global shipping industry. In conversation with TED’s Lindsay Levin, Christiansen shares his company’s ambitious goal to decarbonize their heavy-emitting business by 2040, highlighting how they’ve started implementing solutions like using green methanol as fuel in their container ships and deploying electric trucks in the US. He also points out the challenges in scaling green fuel production, price issues due to the high cost of green fuels and the need for collaborations across the value chain to manage these obstacles. Despite these challenges, Christiansen remains optimistic, making the case that the added cost to consumers for using green shipping methods is far outweighed by the urgently needed environmental benefits.

In conversation with TED’s Lindsay Levin, Bo Cerup-Simonsen, CEO of the Mærsk Mc-Kinney Møller Center for Zero Carbon Shipping, discusses the essential role of their center in orchestrating systemic, global collaboration to tackle large-scale environmental challenges. Discussing the center’s origins, purpose and the strides it’s made in technological, commercial and regulatory spaces, Cerup-Simonsen highlights the push towards green alternatives, like green methanol and ammonia, in global shipping. Through tangible initiatives like “green corridors,” which enable end-to-end zero-carbon shipping between selected ports, they’re fostering cross-industry collaboration to accelerate the green transition and sharing lessons learned in combating the uncertainty hindering decisive action from companies and nations.

Mayor of Detroit Mike Duggan speaks at Session 2 of TED Countdown Summit on July 12, 2023, at the Fillmore Detroit in Detroit, Michigan. (Photo: Nick Hagen / TED)

Mike Duggan is serving his third term as mayor of Detroit, and he’s dead set on building the city’s climate responsiveness. His proposal is a unique one: to transform blighted, vacant lots into solar farms throughout the city. He describes how, with the buy-in of Detroiters themselves, he plans to start building these farms in different neighborhoods with the aim of powering all of Detroit’s municipal buildings and cleaning up dilapidated, vacant land from the city’s manufacturing past.

Public health social worker Laprisha Berry Daniels speaks at Session 2 of TED Countdown Summit on July 12, 2023, at the Fillmore Detroit in Detroit, Michigan. (Photo: Nick Hagen / TED)

Like many cities, Detroit is already feeling the effects of climate change. In the past 10 years, two major floods have cost the city more than a billion dollars in damages. The challenge of climate change may be daunting, but human beings have moved from place to place and adapted to changes in climate (both environmental and social) throughout history. For inspiration, public health social worker Laprisha Berry Daniels mines the survival strategies her grandparents learned after leaving the Jim Crow South to settle in Detroit. The climate crisis may be unprecedented, but Daniels says we can still prepare for it by embracing the lessons of the past. First, we must accept the reality of climate change and prepare for it. Second, we should embrace the power of mutual aid. Lastly, we should empower communities to adapt through community-led planning.

Transforming: Notes from Session 3 of Countdown Summit

“Breathing clean air is every child’s human right,” says Rosamund Adoo-Kissi-Debrah at Session 3 of the TED Countdown Summit on October 13, 2021 in Edinburgh, Scotland. (Photo: Gilberto Tadday / TED)

When looking to make big change, you can’t be shy about it — and Countdown is as much about boldly transforming the systems already in place as it is about creating new ones.

Working to reshape harder-to-abate industries like oil, gas, cement and aviation, the pioneering speakers of Session 3 share tangible solutions and groundbreaking ideas that will get us all to a healthier planet.

The event: Countdown Summit: Session 3, hosted by Future Stewards cofounder Lindsay Levin and TED’s Chris Anderson, at the Edinburgh International Conference Centre in Edinburgh, Scotland on Wednesday, October 13, 2021

Speakers: Bjørn Otto Sverdrup, Ryah Whalen, Rosamund Adoo-Kissi-Debrah, Shweta Narayan, Hongqiao Liu, Mahendra Singhi, Rachel Kyte, Vera Songwe, Susan Ruffo

Performance: Inviting the audience to clap and sway to their vibrantly playful sound, legendary Scottish indie-pop band Belle and Sebastian give a bright rendition of Joni Mitchell’s “Big Yellow Taxi” and their own “Song for Sunshine.”

The talks in brief:

“Daring to say ‘net-zero’ changes minds — it shifts your mindset from defensive to proactive, from incremental change to having your eyes on the end goal,” says Bjørn Otto Sverdrup at Session 3 of the TED Countdown Summit on October 13, 2021 in Edinburgh, Scotland. (Photo: Bret Hartman / TED)

Bjørn Otto Sverdrup, Chair of the Executive Committee of the Oil and Gas Climate Initiative, sustainability expert

Big idea: Bringing the oil and gas industry to a net-zero emissions state is key to curbing climate change.

Why? Responsible for a significant chunk of global carbon emissions, the oil and gas industry needs to make a sharp turn into sustainable territory. Bjørn Otto Sverdrup leads the Oil and Gas Climate Initiative, an organization that brings together twelve of the world’s largest oil and gas companies in an effort to spearhead what he calls the 1/4/20 challenge, named after the 20 gigatons of emissions produced annually by the industry. Their goal is for the industry to achieve net-zero emissions — a daunting pivot that demands brazen policy changes, new technologies and a top-down rethink of how we consume energy. But before logistical difficulties can be fully solved, we need a fundamental transformation of how we think and what we believe is possible. “Daring to say ‘net-zero’ changes minds,” says Sverdrup. “It shifts your mindset from defensive to proactive, from incremental change to having your eyes on the end goal.”


Ryah Whalen talks about decarbonizing aviation at Session 3 of the TED Countdown Summit on October 13, 2021 in Edinburgh, Scotland. (Photo: Gilberto Tadday / TED)

Ryah Whalen, innovator and aviation expert

Big idea: There are three big things that need to be addressed if the flying industry is to get off the ground on climate action.

What are they? Air travel builds bridges and connects us, it takes people to new lives and experiences — but it also comes at a cost to the planet. Ryah Whalen points out that it’s not an easy task to decarbonize flying; planes manufactured today have a lifespan of about 30 years, meaning the planes we create and fly in today will still be in the skies come 2050. If nothing’s done in the industry, air travel stands to create almost a quarter of the world’s emissions yearly moving forward. To reroute from a polluted future, Whalen breaks the problem down into three sections of the industry that need to be addressed to stave off emission growth. First, aircraft design must be coupled with a thorough change of every layer of air traffic management, down to individual pilot behaviors. Second, we need to switch to biofuels and bring their costs down. And finally, sustainable innovations like hybrid-electric aircraft and green hydrogen need to create rapid progress at scale. While challenges lie ahead — notably the billions in investments needed for change — the world and lives are at stake. Individual choices to limit flying can only get us so far. If we want any hope of getting to zero emissions, it will take collective action from all parts of the air travel industry.


Rosamund Adoo-Kissi-Debrah, grassroots campaigner 

Big idea: Breathing clean air is every child’s human right, and governments have a duty to protect it.

Why? Linked to premature deaths across the globe, air pollution is an invisible calamity — and unsafe air is especially bad for children. Grassroots campaigner Rosamund Adoo-Kissi-Debrah shares the heartrending story of her daughter Ella, whose asthma was triggered to a fatal point by unsafe levels of air pollution, and tragically, was the first person in the world to have air pollution listed as a cause of death on her death certificate. “8.7 million people a year are dying from heart attacks, asthma, cancer and other illnesses,” explains Adoo-Kissi-Debrah, and the fossil fuels causing air pollution are a contributor to this tragic statistic. She urges the world to embrace a solution that already exists: to shift from toxic fuels to clean, electrified, public transport and, most importantly, to mobilize and demand clean air.


“It’s impossible to have healthy people on a sick planet,” says Shweta Narayan at Session 3 of the TED Countdown Summit on October 13, 2021 in Edinburgh, Scotland. (Photo: Bret Hartman / TED)

Shweta Narayan, climate and health campaigner

Big idea: As greenhouse gases and toxic pollutants encroach on both our atmosphere and our bodies, ancient wisdom offers humanity hope in this new phase of civilization, where individual well-being and environmental health intersect. 

How? Environmental destruction is the biggest global health issue threatening humanity today — straining infrastructure and power grids, spurring pandemics and causing pollution. Shweta Narayan introduces a new perspective: by viewing climate change and degradation through the lens of the Hippocratic Oath — an ancient set of ethical standards sworn by physicians — every person has a role to play in ecological survival. Narayan encourages us to place “first do no harm” to the planet at the heart of our all of our choices. “It’s impossible to have healthy people on a sick planet,” says Shweta Narayan.


Hongqiao Liu talks about China’s role in curbing climate change at Session 3 of the TED Countdown Summit on October 13, 2021 in Edinburgh, Scotland. (Photo: Bret Hartman / TED)

Hongqiao Liu, journalist and policy expert

Big idea: As the world’s largest carbon emitter (and its second-largest economy), China plays a pivotal role in mitigating climate change. The steps it takes towards becoming net-zero by 2060 are crucial on a global scale. 

How? In 2020, Chinese president Xi Jinping pledged to the UN that China would both peak its emissions by 2030 and achieve net-zero emissions by 2060 — a change that will require action at an unheard-of scale and speed, explains environmental journalist Hongqiao Liu. While it’s still reliant on fossil fuels to drive its economy, China is also a world leader in renewable energy and sustainable infrastructure. This is already transforming energy consumption — but is it enough? Citing economist Zou Ji, Liu is hopeful for change. In addition to burgeoning green energy production, which may allow China to reach peak emissions years ahead of its goal, the country’s leaders are also now downplaying GDP as a metric of economic health, which could be a crucial step towards sustainable growth — and one which could inspire a paradigm shift around the world.


Mahendra Singhi, CEO, Dalmia Cement

Big idea: With carbon-capture and neutralizing technology, notoriously hard-to-abate sectors like cement could transform it into carbon-negative industries.

How? Cement is vital to modernizing infrastructure of all kinds in the developing world — but manufacturing it comes at an enormous environmental cost. Producing and transporting a single ton of cement still emits half a ton of CO2, even after decades of efforts to reduce its carbon footprint. At Dalmia Cement, one of the largest producers of cement in India, Mahendra Singhi is determined to transform the industry into a sustainable one. To make cement carbon-negative, the company is targeting the two largest sources of CO2 emissions in the manufacturing pipeline: the fossil fuels used to process and transport the material and clinkerisation, the chemical process that makes cement a usable product. And while adopting renewable energy sources like electric cars and green fuel is relatively straightforward, the more difficult challenge is turning the CO2 produced by the clinkerisation process — which represents up to half of the CO2 emissions associated with cement — into a productive material. Large-scale carbon capture plants might be the ticket to sparing this CO2 from the atmosphere and transforming it into something usable. Though still a nascent technology, Dalmia’s recent feasibility study on the subject “proved that it is technologically and economically viable,” says Singhi. “From 2040, my cement manufacturing process will not emit a gram of CO2.”


Rachel Kyte, sustainable development diplomat and activist

Big idea: If we want clean cooling systems that don’t contribute to global warming, we must tackle issues of sustainability and fairness at the same time.

How? Global surface temperatures are at an all-time high — but the way we cool down is heating up the planet even more. Most traditional cooling methods are energy inefficient and depend on polluting refrigerants like hydrofluorocarbons (HFCs). Activist Rachel Kyte, who works to identify paths to cleaner energy systems, outlines four steps to climbing out of this intensely pollutive and disparate system. First, we need to move away from building designs that center on traditional air conditioning — think ultra-white, heat reflective paint and garden-rich rooftops. According to Kyte, the cooling technologies we use need to be at least 50 percent more efficient than today’s most sustainable unit. Next, governments must commit to HFC-free technologies on a global scale. Finally, we need cold chains for perishable medicines, food and other products — for every community on the planet. While some bask in air-conditioned suburban homes, billions of people around the world don’t even have access to the basics. “What is scary is that we are not having enough conversations in enough places and driving enough investments into affordable, non-polluting efficient solutions for cooling for everyone,” says Kyte.


“We must collectively ask the markets to recognize and adequately reward Africa’s contribution to slowing climate change by putting a price on carbon,” says Vera Songwe at Session 3 of the TED Countdown Summit on October 13, 2021 in Edinburgh, Scotland. (Photo: Gilberto Tadday / TED)

Vera Songwe, Under-Secretary-General of the United Nations and Executive Secretary of the Economic Commission for Africa

Big idea: The peatlands of the Congo Basin are an invaluable resource in the fight against climate change, and protecting them via a responsible development plan should be a global priority.

Why? Recently identified as one of the world’s most efficient carbon sinks, the peatlands of the Central African Congo Basin absorb a sizeable portion of global emissions. But, like many other biodiverse territories, it’s on the verge of being churned into grist for the capitalist mill. Vera Songwe believes that money and resources should flow in the other direction. At a price of $50 per unit of the 30 billion tons of carbon the peatlands soak up, a $1.5 trillion Peatlands Development Fund could be established to transform the economic realities of communities in the region. A budget that size would ensure robust local infrastructure, create jobs  and, most importantly, nudge regional economic development in the direction of preservation instead of exploitation. “This is not just about decarbonization, it is about development with dignity,” says Songwe. “We must collectively ask the markets to recognize and adequately reward Africa’s contribution to slowing climate change by putting a price on carbon.”


Susan Ruffo, ocean expert

Big idea: The ocean is an unsung hero in the story of climate change, providing readymade solutions to the climate crisis — if we are smart enough to recognize them.

Why? A vital part of our life support system here on earth, the ocean produces half of the earth’s oxygen (that’s one in every two breaths you take). It helps regulate the planet’s temperature and absorbs anywhere from a quarter to a third of the CO2 we put into the atmosphere — making it the world’s largest carbon sink. The ocean does a lot for us already — our first priority should be not messing that up, says Susan Ruffo, Senior Advisor for Ocean and Climate at United Nations Foundation. Beyond that, there’s a thrilling range of ocean-based climate solutions we could tap into — from the carbon-absorbing power of mangroves and salt marshes to dense oysters reefs that could lower the risk of major flood damage — if we start to appreciate the ocean’s role in helping us address the climate crisis.

Mark your calendar: Tune in to the Countdown Global Livestream on October 30, 2021. This virtual event will lay out a credible and realistic pathway to a zero-carbon future. Save the date.

Climate hope: Notes from Session 4 of TEDMonterey

Maria Gallucci comes ferrying good news: there’s a way to clean up the shipping industry that’s green, economically lean and can be made with planet-friendly machines. She speaks at TEDMonterey: The Case for Optimism on August 2, 2021. (Photo: Bret Hartman / TED)

The scale of the climate crisis is so daunting that it can be easy to get dragged down into pessimism. But at Session 4, six speakers — call them unexpected heroes of the future — told a different story of how we might beat this thing. They speak on an exciting range of phenomena and possibilities that could make a huge difference in our effort to draw down gigatons of CO2 and regain a livable environment.

The event: TEDMonterey: Session 4, hosted by TED’s Chris Anderson on Monday, August 2, 2021

Speakers: Ma Jun, Carlos M. Duarte, Maria Gallucci, Susan Graham, Jamie C. Beard

Special guest: Nigel Topping, the UK’s High-Level Climate Action Champion for COP26, chats with Chris Anderson about the prospects of increased climate ambition ahead of the UN climate conference this November and gives an update on Race to Zero, a global campaign to mobilize leadership on this crucial issue.


Seagrass is an unsung hero in the fight against climate change, says Carlos M. Duarte. He talks about his work mapping seagrass locations across the world’s oceans with the help of turtles and tiger sharks at TEDMonterey: The Case for Optimism on August 2, 2021(Photo: Bret Hartman / TED)

Carlos M. Duarte, marine scientist

Big idea: Seagrass is an unsung hero in the fight against climate change. But disease, dredging and the deterioration of our oceans’ water quality threaten to wipe out this vital species — unless we take immediate action to protect it.

How? You’ve likely seen seagrass — it grows along the shore of every continent except Antarctica — but did you recognize this humble plant as a champion of carbon sequestration? According to Carlos M. Duarte, seagrass is responsible for drawing down one-third of the carbon that accumulates in the seafloor each year! Seagrass also filters plastic from our oceans and, during hurricanes and tropical storms, its massive roots and rhizomes reinforce the seafloor and act as the first line of defense for our coastlines. The bad news: a disease in the Atlantic killed off vast colonies of seagrass in the 1930s and, since then, water pollution, dredging, trawling and anchor damages have worsened this plant’s plight. But Duarte and the team at Beneath the Waves are working to save our seagrass. They are mapping seagrass locations across the world’s oceans (using turtles and tiger sharks!), promoting policies to improve water quality, restoring damaged seagrass meadows and planting new ones. With enough action, Duarte believes we can protect plant heroes like seagrass and rebuild marine life by 2050.


Maria Gallucci, journalist

Big idea: The maritime shipping industry must become climate-friendly — but have no fear, green ammonia is here.

How? Every day, tens of thousands of cargo ships criss-cross the ocean carrying the food we eat, the clothes we wear and the cars we drive. At the same time, they spew fumes and black smoke from heavily polluting fossil fuels into the atmosphere. But Maria Galluci comes ferrying good news: there’s a way to clean up the industry, beyond reverting to pre-industrial sailing ships, that’s green, economically lean and can be made with planet-friendly machines. Green ammonia could be a game-changing way to turn the tides for the shipping industry, as it’s not carbon-based; rather, it’s made up of nitrogen and hydrogen (the molecules that make up air and water). Galluci lays out how this alternative fuel could become an industry-standard reality — from environment-friendly manufacturing processes combined with plunging renewable energy costs to combustion engines and fuel cells. So, what will it take to get an ammonia-powered shipping industry mainstream? She says a rough parallel can be found in the rise of electric cars. Hopefully, one day soon, the incoming freighters will not bring the smell of diesel and carbon emissions, but the scent of a fresh sea breeze.


Susan Graham, environmentalist, entrepreneur

Big idea: We can use drone technology and ecology-trained AI to restore degraded land and revive complex, biodiverse ecosystems.

How? Land restoration is more than planting trees, says Susan Graham. If we want to revive the more than two billion hectares of degraded land on the planet, we need to embrace complex solutions. According to Graham, drones and AI can help us restore areas damaged by industrial activities, natural disasters and invasive species by planting the right mix of native vegetation. In Australia, for instance, Graham and her team are helping restore the forest ina territory depleted and degraded by coal mining. Plus, this technology can work at enormous scales — meaning we can use it to revive the beauty and complexity of native ecosystems both in a single forest and across the planet.


Is it possible to eat a hamburger without killing a cow? Isha Datar explores the exhilarating future of cellular agriculture at TEDMonterey: The Case for Optimism on August 2, 2021 (Photo: Bret Hartman / TED)

Isha Datar, cellular agriculture ecosystem builder

Big idea: Cellular agriculture makes it possible to eat meat without the negative consequences of industrial farming and processing.

How? What if you could eat chicken nuggets without ever killing a chicken? Or a hamburger without killing a cow? It’s possible through cellular agriculture, says Isha Datar, and this new means of meat production will transform our food systems. Here’s how it works: scientists take a biopsy from a living animal (like a chicken), extract the cells and then put them in a liquid medium that provides everything these cells need to grow. Instead of cramped cages stuffed with genetically modified hens, large bioreactors will produce boneless, skinless white meat without byproducts like feathers, beaks and bones. But this process isn’t just better for the birds; it’s better for all of us. Early estimates suggest cultured meat would require 99 percent less land, produce 78 percent fewer greenhouse gas emissions and use 82 percent less water than industrial meat farming and production. And meat is only the beginning! We could use this technology to grow vanilla without clear-cutting the rainforest or produce silk without silkworms. As Datar says, this isn’t a new product — this is our once-in-a-lifetime opportunity to get a second chance at agriculture.


Climate Action Tracker, a tracking initiative holding governments accountable for their Paris Agreement commitments

Big idea: The actions governments take in 2021 to reduce emissions will determine if the world is on track to limit global warming to 1.5 degrees, so the time to act is now. Is there a way to hold them accountable for the goals set at the 2015 Paris Agreements?

An answer: In 2015, countries participating in the Paris Agreements agreed to cut greenhouse gas emissions in half by 2030 and bring carbon dioxide emissions to net zero by 2050. Climate Action Tracker is a platform designed not only to keep track of our progress towards reaching the Paris benchmarks, but also to pinpoint exactly who isn’t shouldering their fair share of the burden. The platform gives us a status update on what’s working, and what isn’t.


Ma Jun, environmentalist, scholar

Big idea: By making pollution information public in China, citizens can hold global brands accountable for pollution control. 

How? Transparency is the key to speeding environmental change at scale in China, says Ma Jun. He’s the creator of Blue Map, an app that tracks pollution violations and color codes factories based on their records of environmental contamination: green and blue are good; red and yellow are bad. This data makes it possible, at a glance, for citizens to monitor corporate violations and micro-report these offenses to government agencies. To help China achieve its goal of carbon neutrality by 2060, Ma and his team have also developed the Blue Map for Carbon Zero, which color codes cities and provinces based on carbon emissions. And he plans to expand the Blue Map project to include plastic, waste and even biodiversity to motivate more companies and more people to reduce their environmental impact and leave a healthier world for all of us. 


Jamie C. Beard explains how recent innovations in drill technology, such as the ability to drill in curves, have made geothermal energy enticingly feasible. She speaks at TEDMonterey: The Case for Optimism on August 2, 2021 (Photo: Bret Hartman / TED)

Jamie C. Beard, technologist, climate activist

Big idea: Geothermal energy could provide us with a clean way to power the globe.

How? What if oil and gas companies could equip us with the infrastructure needed to clean our power grids? Jamie C. Beard advocates for geothermal energy, which requires drilling deep into the earth to access the planet’s natural heat, and explains how recent innovations in drill technology, such as the ability to drill in curves, have made this alternative energy feasible. But to bring geothermal energy to scale, we need to drill all over the world — and drill a lot. Fortunately, the oil and gas industry already has the technology, infrastructure and training to bring geothermal energy online fast. In fact, she says, many geothermal startups are founded by oil and gas veterans. The industry known for its dirty pollution could easily become a pioneer in curbing climate change. “We flip the switch, and we have green drilling,” she says. “This is simply a pivot — from hydrocarbons to heat.”

Weaving Community: Notes from Session 1 of TEDSummit 2019

The stage is set for TEDSummit 2019: A Community Beyond Borders! During the opening session, speakers and performers explored themes of competition, political engagement and longing — and celebrated the TED communities (representing 84 countries) gathered in Edinburgh, Scotland to forge TED’s next chapter.

The event: TEDSummit 2019, Session 1: Weaving Community, hosted by Bruno Giussani and Helen Walters

When and where: Sunday, July 21, 2019, 5pm BST, at the Edinburgh Convention Centre in Edinburgh, Scotland

Speakers: Pico Iyer, Jochen Wegner, Hajer Sharief, Mariana Lin, Carole Cadwalladr, Susan Cain with Min Kym

Opening: A warm Scottish welcome from raconteur Mackenzie Dalrymple

Music: Findlay Napier and Gillian Frame performing selections from The Ledger, a series of Scottish folk songs

The talks in brief:

“Seeming happiness can stand in the way of true joy even more than misery does,” says writer Pico Iyer. (Photo: Ryan Lash / TED)

Pico Iyer, novelist and nonfiction author

Big idea: The opposite of winning isn’t losing; it’s failing to see the larger picture.

Why? As a child in England, Iyer believed the point of competition was to win, to vanquish one’s opponent. Now, some 50 years later and a resident of Japan, he’s realized that competition can be “more like an act of love.” A few times a week, he plays ping-pong at his local health club. Games are played as doubles, and partners are changed every five minutes. As a result, nobody ends up winning — or losing — for long. Iyer has found liberation and wisdom in this approach. Just as in a choir, he says, “Your only job is to play your small part perfectly, to hit your notes with feeling and by so doing help to create a beautiful harmony that’s much greater than the sum of its parts.”

Quote of the talk: “Seeming happiness can stand in the way of true joy even more than misery does.”


Jochen Wegner, journalist and editor of Zeit Online

Big idea: The spectrum of belief is as multifaceted as humanity itself. As social media segments us according to our interests, and as algorithms deliver us increasingly homogenous content that reinforces our beliefs, we become resistant to any ideas — or even facts — that contradict our worldview. The more we sequester ourselves, the more divided we become. How can we learn to bridge our differences?

How? Inspired by research showing that one-on-one conversations are a powerful tool for helping people learn to trust each other, Zeit Online built Germany Talks, a “Tinder for politics” that facilitates “political arguments” and face-to-face meetings between users in an attempt to bridge their points-of-view on issues ranging from immigration to same-sex marriage. With Germany Talks (and now My Country Talks and Europe Talks) Zeit has facilitated conversations between thousands of Europeans from 33 countries.

Quote of the talk: “What matters here is not the numbers, obviously. What matters here is whenever two people meet to talk in person for hours, without anyone else listening, they change — and so do our societies. They change, little by little, discussion by discussion.”


“The systems we have nowadays for political decision-making are not from the people for the people — they have been established by the few, for the few,” says activist Hajer Sharief. She speaks at TEDSummit: A Community Beyond Borders, July 21, 2019, in Edinburgh, Scotland. (Photo: Bret Hartman / TED)

Hajer Sharief, activist and cofounder of the Together We Build It Foundation

Big Idea: People of all genders, ages, races, beliefs and socioeconomic statuses should participate in politics.

Why? Hajer Sharief’s native Libya is recovering from 40 years of authoritarian rule and civil war. She sheds light on the way politics are involved in every aspect of life: “By not participating in it, you are literally allowing other people to decide what you can eat, wear, if you can have access to healthcare, free education, how much tax you pay, when can you retire, what is your pension,” she says. “Other people are also deciding whether your race is enough to consider you a criminal, or if your religion or nationality are enough to put you on a terrorist list.” When Sharief was growing up, her family held weekly meetings to discuss family issues, abiding by certain rules to ensured everyone was respectful and felt free to voice their thoughts. She recounts a meeting that went badly for her 10-year-old self, resulting in her boycotting them altogether for many years — until an issue came about which forced her to participate again. Rejoining the meetings was a political assertion, and it helped her realize an important lesson: you are never too young to use your voice — but you need to be present for it to work.

Quote of talk: “Politics is not only activism — it’s awareness, it’s keeping ourselves informed, it’s caring for facts. When it’s possible, it is casting a vote. Politics is the tool through which we structure ourselves as groups and societies.”


Mariana Lin, AI character designer and principal writer for Siri

Big idea: Let’s inject AI personalities with the essence of life: creativity, weirdness, curiosity, fun.

Why? Tech companies are going in two different directions when it comes to creating AI personas: they’re either building systems that are safe, flat, stripped of quirks and humor — or, worse, they’re building ones that are fully customizable, programmed to say just what you want to hear, just how you like to hear it. While this might sound nice at first, we’re losing part of what makes us human in the process: the friction and discomfort of relating with others, the hard work of building trusting relationships. Mariana Lin calls for tech companies to try harder to truly bring AI to life — in all its messy, complicated, uncomfortable glory. For starters, she says, companies can hire a diverse range of writers, creatives, artists and social thinkers to work on AI teams. If the people creating these personalities are as diverse as the people using it — from poets and philosophers to bankers and beekeepers — then the future of AI looks bright.

Quote of the talk: “If we do away with the discomfort of relating with others not exactly like us, with views not exactly like ours — we do away with what makes us human.”


In 2018, Carole Cadwalladr exposed Cambridge Analytica’s attempt to influence the UK Brexit vote and the 2016 US presidential election via personal data on Facebook. She’s still working to sound the alarm. She speaks at TEDSummit: A Community Beyond Borders, July 21, 2019, in Edinburgh, Scotland. (Photo: Bret Hartman / TED)

Carole Cadwalladr, investigative journalist, interviewed by TED curator Bruno Giussani

Big idea: Companies that collect and hoard our information, like Facebook, have become unthinkably powerful global players — perhaps more powerful than governments. It’s time for the public hold them accountable.

How? Tech companies with offices in different countries must obey the laws of those nations. It’s up to leaders to make sure those laws are enforced — and it’s up to citizens to pressure lawmakers to further tighten protections. Despite legal and personal threats from her adversaries, Carole Cadwalladr continues to explore the ways in which corporations and politicians manipulate data to consolidate their power.

Quote to remember: “In Britain, Brexit is this thing which is reported on as this British phenomenon, that’s all about what’s happening in Westminster. The fact that actually we are part of something which is happening globally — this rise of populism and authoritarianism — that’s just completely overlooked. These transatlantic links between what is going on in Trump’s America are very, very closely linked to what is going on in Britain.”


Susan Cain meditates on how the feeling of longing can guide us to a deeper understanding of ourselves, accompanied by Min Kym on violin, at TEDSummit: A Community Beyond Borders. July 21, 2019, Edinburgh, Scotland. (Photo: Ryan Lash / TED)

Susan Cain, quiet revolutionary, with violinist Min Kym

Big idea: Life is steeped in sublime magic that you can tap into, opening a whole world filled with passion and delight.

How? By forgoing constant positivity for a state of mind more exquisite and fleeting — a place where light (joy) and darkness (sorrow) meet, known to us all as longing. Susan Cain weaves her journey in search for the sublime with the splendid sounds of Min Kym on violin, sharing how the feeling of yearning connects us to each other and helps us to better understand what moves us deep down.

Quote of the talk: “Follow your longing where it’s telling you to go, and may it carry you straight to the beating heart of the perfect and beautiful world.”

A first glimpse at the TEDSummit 2019 speaker lineup

Par : TED Staff

At TEDSummit 2019, more than 1,000 members of the TED community will gather for five days of performances, workshops, brainstorming, outdoor activities, future-focused discussions and, of course, an eclectic program of TED Talks — curated by TED Global curator Bruno Giussani, pictured above. (Photo: Marla Aufmuth / TED)

With TEDSummit 2019 just two months away, it’s time to unveil the first group of speakers that will take to the stage in Edinburgh, Scotland, from July 21-25.

Three years ago, more than 1,000 members of the TED global community convened in Banff, Canada, for the first-ever TEDSummit. We talked about the fracturing state of the world, the impact of technology and the accelerating urgency of climate change. And we drew wisdom and inspiration from the speakers — and from each other.

These themes are equally pressing today, and we’ll bring them to the stage in novel, more developed ways in Edinburgh. We’ll also address a wide range of additional topics that demand attention — looking not only for analysis but also antidotes and solutions. To catalyze this process, half of the TEDSummit conference program will take place outside the theatre, as experts host an array of Discovery Sessions in the form of hands-on workshops, activities, debates and conversations.

Check out a glimpse of the lineup of speakers who will share their future-focused ideas below. Some are past TED speakers returning to give new talks; others will step onto the red circle for the first time. All will help us understand the world we currently live in.

Here we go! (More will be added in the coming weeks):

TED original podcast The TED Interview kicks off Season 2

Par : TED Staff

TED returns with the second season of The TED Interview, a long-form podcast series that features Chris Anderson, head of TED, in conversation with leading thinkers. The podcast is an opportunity to reconnect with renowned speakers and dive deeper into their ideas within a different global climate. This season’s guests include Bill Gates, Monica Lewinsky, Tim Ferriss, Susan Cain, Yuval Noah Harari, David Brooks, Amanda Palmer, Kai-Fu Lee, Sylvia Earle, Andrew McAfee and Johann Hari. Plus, a bonus episode with Roger McNamee that was recorded live at TED2019.

Listen to the first episode with Bill Gates now on Apple Podcasts.

In its first season, The TED Interview played host to extraordinary conversations — such as the writer Elizabeth Gilbert on the death of her partner, Rayya Elias; Sir Ken Robinson on the education revolution; and Ray Kurzweil on what the future holds for humanity.

Season two builds on this success with new ideas from some of TED’s most compelling speakers. Listeners can look forward to hearing from Bill Gates on the future of technology and philanthropy; musician Amanda Palmer on how the future of creativity means asking for what you want; Susan Cain on introversion and other notable past speakers.

“Ideas are not static — they don’t land perfectly formed in an unchanging world,” said Chris Anderson. “As times change, opinions shift and new research is published, ideas must be iterated on. The TED Interview is a remarkable platform where past speakers can further explain, amplify, illuminate and, in some cases, defend their thinking. Season two listeners can expect a front-row seat as we continue to explore the theory behind some of TED’s most well-known talks.”

The TED Interview launches today and releases new episodes every Wednesday. It is available on Apple Podcasts, the TED Android app or wherever you like to listen to podcasts. Season 2 features 12 episodes, each being roughly an hour long. Collectively the Season Two speakers have garnered over 100 million views through their TED Talks.

The TED Interview is proudly sponsored by Klick Health, the world’s largest independent health agency. They use data, technology and creativity to help patients and healthcare professionals learn about and access life-changing therapies.

TED’s content programming extends beyond its signature TED Talk format with six original podcasts. Overall TED’s podcasts were downloaded over 420 million times in 2018 and have been growing 44% year-over-year since 2016. Among others, The TED Interview joins notable series like Sincerely, X, where powerful ideas are shared anonymously, which recently launched its second season exclusively on the Luminary podcast app.
