Playlist (18 talks): How do you solve a problem like the climate crisis? 16:46Now playingHave we used up all our resources? Have we filled up all the livable space on Earth? Paul Gilding suggests we have, and the possibility of devastating consequences, in a talk that's equal parts terrifying and, oddly, hopeful. 19:22Now playingPhotographer James Balog shares new image sequences from the Extreme Ice Survey, a network of time-lapse cameras recording glaciers receding at an alarming rate, some of the most vivid evidence yet of climate change. 18:16Now playingLegendary ocean researcher Sylvia Earle shares astonishing images of the ocean — and shocking stats about its rapid decline — as she makes her TED Prize wish: that we will join her in protecting the vital blue heart of the planet. 14:36Now playingAs Vicki Arroyo says, it's time to prepare our homes and cities for our changing climate, with its increased risk of flooding, drought and uncertainty. She illustrates this inspiring talk with bold projects from cities all over the world — local examples of thinking ahead. 17:52Now playing"I don't think we're going to make it," John Doerr says in an emotional talk about climate change and investment. To create a world fit for his daughter to live in, he says, we need to invest now in clean, green energy. 15:58Now playingEnvironmental scientist David Keith proposes a cheap, effective, shocking means to address climate change: What if we injected a huge cloud of ash into the atmosphere to deflect sunlight and heat? 4:11Now playingPhotographer Camille Seaman shoots icebergs, showing the world the complex beauty of these massive, ancient chunks of ice. Dive in to her photo slideshow, "The Last Iceberg." 17:55Now playingDiving under the Antarctic ice to get close to the much-feared leopard seal, photographer Paul Nicklen found an extraordinary new friend. Share his hilarious, passionate stories of the polar wonderlands, illustrated by glorious images of the animals who live on and under the ice. 17:20Now playingBeverly + Dereck Joubert live in the bush, filming and photographing lions and leopards in their natural habitat. With stunning footage (some never before seen), they discuss their personal relationships with these majestic animals — and their quest to save the big cats from human threats. 9:47Now playingNature’s beauty can be easily missed — but not through Louie Schwartzberg’s lens. His stunning time-lapse photography, accompanied by powerful words from Benedictine monk Brother David Steindl-Rast, serves as a meditation on being grateful for every day. (Filmed at TEDxSF.) 22:01Now playingWith stunning photos and stories, National Geographic Explorer Wade Davis celebrates the extraordinary diversity of the world's indigenous cultures, which are disappearing from the planet at an alarming rate. 18:36Now playingIn an emotionally charged talk, MacArthur-winning activist Majora Carter details her fight for environmental justice in the South Bronx — and shows how minority neighborhoods suffer most from flawed urban policy. 27:54Now playingIn this brand-new slideshow (premiering on TED.com), Al Gore presents evidence that the pace of climate change may be even worse than scientists recently predicted. He challenges us to act. 17:14Now playingIn the Gulf oil spill's aftermath, Lisa Margonelli says drilling moratoriums and executive ousters make for good theater, but distract from the issue at its heart: our unrestrained oil consumption. She shares her bold plan to wean America off of oil — by confronting consumers with its real cost. (Filmed at TEDxOilSpill.) 15:15Now playingWhat's the key to using alternative energy, like solar and wind? Storage — so we can have power on tap even when the sun's not out and the wind's not blowing. In this accessible, inspiring talk, Donald Sadoway takes to the blackboard to show us the future of large-scale batteries that store renewable energy. As he says: "We need to think about the problem differently. We need to think big. We need to think cheap." 10:25Now playingInspired by an abalone shell, Angela Belcher programs viruses to make elegant nanoscale structures that humans can use. Selecting for high-performing genes through directed evolution, she's produced viruses that can construct powerful new batteries, clean hydrogen fuels and record-breaking solar cells. In her talk, she shows us how it's done. 12:50Now playingOur energy future depends on nuclear fusion, says Michel Laberge. The plasma physicist runs a small company with a big idea for a new type of nuclear reactor that could produce clean, cheap energy. His secret recipe? High speeds, scorching temperatures and crushing pressure. In this hopeful talk, he explains how nuclear fusion might be just around the corner. 17:51Now playingTop climate scientist James Hansen tells the story of his involvement in the science of and debate over global climate change. In doing so he outlines the overwhelming evidence that change is happening and why that makes him deeply worried about the future.

Michel Laberge: Kako bi usklađeni udarci čekićima mogli stvarati nuklearnu fuziju. Naša energetska budućnost ovisi o nuklearnoj fuziji, kaže Michel Laberge. Fizičar koji se bavi plazmom ima malu tvrtku s velikom idejom za novi tip nuklearnog reaktora koji bi mogao prozivesti čistu i jeftinu energiju. Njegov tajni recept? Velike brzine, visoke temperature i snažan tlak. U ovom govoru punom nade objašnjava kako bi nuklearna fuzija mogla biti vrlo blizu.
