5. TED Talks John Doerr Salvation (and profit) in greentech
"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.
6. TED Talks David Keith A critical look at geoengineering against climate change
Environmental 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?
7. TED Talks Camille Seaman Haunting photos of polar ice
Photographer 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."
8. TED Talks Paul Nicklen Tales of ice bound wonderlands
Diving 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.
9. TED Talks Beverly + Dereck Joubert Life lessons from big cats
Beverly + 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.
10. TED Talks Louie Schwartzberg Nature. Beauty. Gratitude.
Nature’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.
11. TED Talks Wade Davis Dreams from endangered cultures
With 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.
12. TED Talks Majora Carter Greening the ghetto
In 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.
13. TED Talks Al Gore New thinking on the climate crisis
In 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.
14. TED Talks Lisa Margonelli The political chemistry of oil
In 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.
15. TED Talks Donald Sadoway The missing link to renewable energy
What'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."
16. TED Talks Angela Belcher Using nature to grow batteries
Inspired 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.
17. TED Talks Michel Laberge How synchronized hammer strikes could generate nuclear fusion
Our 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.
18. TED Talks James Hansen Why I must speak out about climate change
Top 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.
