Earth, the planet of sadness

Named a "Hero of the Environment" by Time magazine in 2008, Kim Stanley Robinson writes books that offer a twisted take on how life might be for future generations of humans (and the non-humans we will likely evolve to be). Here, read an excerpt from his novel 2312, which describes Earth of 300 years from now, long after clean tech failed to s...

Welcome to the legible planet

What will it mean when almost anyone can read and understand the world and everything on it, in it, and above it -- in real time, at will? Andrew Blau investigates. Technology advances over the last 30 years mean that we have crossed an invisible threshold: for the first time in human history, we now live on a legible planet. What will blow o...

Planet Protectors: Notes from Session 3 of TEDWomen 2019

The world is experiencing the consequences of climate change and the urgency couldn't be more clear. In Session 3 of TEDWomen 2019, we dug deep into some of the most pressing environmental issues of our time -- exploring solutions and the many ways people across the globe are fighting for change.

Gallery: A love letter to the planet

Ask photojournalists to name a peer they admire, and Sebastião Salgado's name is sure to crop up. The Brazilian is renowned for the long-term projects he undertakes, devoting years at a time to documenting the story of a particular people or the evolution of a certain place. As he describes in the talk he gave at TED2013, his attention to detail...

Planet, Protection: The talks of Session 6 of TED2017

Polar ice doesn't care who's in the White House. It just melts. In the sixth session of TED2017, hosted by TED's Head Curator Chris Anderson, we hear blunt talk on climate change -- taking a 30,000-foot view from the clouds and examining some market-based solutions for cleaning the planet. Below, recaps of the talks from Session 6, in chronol...

These young women might just save the planet

One of anthropologist Margaret Mead’s most famous quotes instructs us: “Never doubt that a small group of thoughtful, committed citizens can change the world: indeed, it’s the only thing that ever has.” We might amend Mead’s observation to honor a group of thoughtful, committed teenagers across the world who are standing up for their lives (...

Taking pictures of the entire planet, every day: Will Marshall at TED2014

"We're on spaceship Earth," begins Will Marshall during Session 9 of TED2014. "It's fragile and finite -- and we need to take care of it." He shows a satellite image of Earth. Yes, it's beautiful, says Marshall, but it's outdated. The information is old, and he says, "We can't fix what we can't see." Satellite imaging, says Marshall, is b...

Announced at TED2018: Explore satellite images with Planet Stories

Back in 2014, Will Marshall took the TED stage to introduce us to his company, Planet, and their proposed fleet of tiny satellites. The goal: to image the planet every day, showing us how Earth changes in near-real time. In 2018, that vision has come good: Every day, a fleet of about 200 small satellites pictures every inch of the planet, ta...

Bird’s-eye science: What we’re learning about the planet using aerial technology

Earth has been around for over 4.5 billion years, and modern humans have inhabited it for the past 200,000. Yet in all that time, we’ve learned surprisingly little about the planet’s landscape and the animals that live on it. This is especially true of remote areas such as the Amazon’s dense jungles, the ocean’s vast coral reefs or the wide-...

Humans have changed the planet. Here's how we design for that now

For most of us, the job of taking care of the planet is very definitely the responsibility of Someone Else. We might have thoughts, we might have standards, we might even have a composting habit, but we more than likely hope and expect that the trained professionals have got this under control. One problem, of course, is that those who are train...

Guess which country does the most good for the planet?

The Good Country Index measures how much each of 125 countries contributes to the planet. Announced at the TEDSalon in Berlin, the Index features some unexpected winners — and even more surprising losers. (Sorry, USA.) Irish people, rejoice! It turns out, your green land is the "goodest" country in the world. That's right. The "goodest." At...

Pluto really is a planet (probably): The meaning of the first close-up photos

Alan Stern is excited. The planetary scientist has been working on sending a probe to Pluto since 1989. During that time, he's seen his planet downgraded to "dwarf planet" status (in 2006) ... but now he's optimistic that Pluto will be reinstated with full planetary honors. Why? Because just-released close-up pictures from the New Horizons probe...

By saving this adorable, elusive wild cat, you could help save the planet (really!)

It's a fact: Dangle a cat video in front of almost anyone, and they’ll drop everything to watch it. It’s something that conservationist and entrepreneur Ashwin Naidu is counting on. He is hoping that fishing cats -- little-known, endangered, wetland-dwelling felines like the one shown above -- grab our attention and galvanize us caring about ...

The 9 limits of our planet ... and how we've raced past 4 of them

Astronomer, actor, role model: TED Fellow Aomawa Shields looks for life on other planets

Aomawa Shields is a woman of "contradictions." An astronomer and astrobiologist, she searches for exoplanets where life might exist by using computer models to calculate the kind of atmosphere they'd need to support it. And she's also a classically trained actor, who -- through her organization Rising Stargirls -- teaches astronomy to middle...

We're another small step closer to finding new Earth-like planets

Some interesting things are going on down here … that might just affect how we see what’s going on out there.

One report studied a concept based on a telescope with a...

A know-it-all gets another chance, JR quips with Stephen Colbert and a plan to give half the planet back to wildlife

If we don’t, he warns, he sees us hurtling toward a “biological holocaust” that could send us the way of the dinosaurs. (Watch his TED Prize talk: ...

Blocking light to see planets beyond the solar system: Jeremy Kasdin at TED2014

"The universe is teeming with planets," and Jeremy Kasdin, an astronomer at Princeton University, wants to see them. Not in the way they've been detected so far, but directly. He wants to build a space telescope that will image a planet around another star and tell if it harbors life. There is probably one per star in the galaxy, and maybe 1...

Extraordinary claims require extraordinary evidence: Tabetha Boyajian at TED2016

Exploring space generates tons of data -- so much data that most of it is studied using algorithms, not human eyes. But algorithms are not very good at being creative.

How will clouds change global warming? Kate Marvel speaks at TED2017

Kate Marvel is a climate scientist -- but she hates weather. She doesn’t want to experience clouds, let alone study them, but they seem to follow her wherever she goes. Clouds are one of the great challenges for climate science: we don't know how they'll react as the planet heats up, and hidden in that uncertainty is the chance of a mirac...
