--> 00:23:58,106 [people screaming] 412 00:24:05,363 --> 00:24:08,366 - As our disaster simulation comes to a fiery end, 413 00:24:08,408 --> 00:24:11,661 I mourn the demise of my beloved Seattle 414 00:24:11,702 --> 00:24:15,873 while wondering, "Why not take Portland instead?" 415 00:24:15,915 --> 00:24:19,293 Major seismic events continue along the Ring of Fire 416 00:24:19,335 --> 00:24:21,003 for the next few weeks. 417 00:24:21,045 --> 00:24:23,131 By now, world leaders recognize that 418 00:24:23,172 --> 00:24:25,925 a lone hacker was behind the cyberattack, 419 00:24:25,967 --> 00:24:28,761 and they try to reopen communications. 420 00:24:28,803 --> 00:24:30,179 But it's too late. 421 00:24:30,221 --> 00:24:33,558 With all this destruction, you might be wondering, 422 00:24:33,599 --> 00:24:36,936 "Why is Earth so damn dangerous anyway?" 423 00:24:39,731 --> 00:24:41,733 Hey, wh--what are you doing here? 424 00:24:41,774 --> 00:24:44,152 You're part of the simulation. 425 00:24:44,193 --> 00:24:47,155 [dramatic music] 426 00:24:47,196 --> 00:24:49,365 * * 427 00:24:49,407 --> 00:24:51,951 [both yelling] 428 00:25:04,714 --> 00:25:06,799 - As our disaster simulation comes to an end, 429 00:25:06,841 --> 00:25:09,969 the Ring of Fire has left its mark on Earth, 430 00:25:10,011 --> 00:25:13,139 and the Disaster Institute lies in ruins. 431 00:25:13,181 --> 00:25:15,683 All part of the simulation, of course. 432 00:25:15,725 --> 00:25:18,978 Someone with a sick sense of humor. 433 00:25:19,020 --> 00:25:23,066 Really? I had to die twice this time? 434 00:25:23,107 --> 00:25:26,319 [sighs] 435 00:25:26,360 --> 00:25:29,822 Well, let's hit the lab and answer the question, 436 00:25:29,864 --> 00:25:32,950 "Why is Mother Nature always trying to kill us?" 437 00:25:34,035 --> 00:25:37,080 Our planet is dangerous, people. 438 00:25:37,121 --> 00:25:40,750 It can burn us, swallow us, crush us, and drown us, 439 00:25:40,792 --> 00:25:42,293 sometimes all at once. 440 00:25:42,335 --> 00:25:43,878 But as far as we can figure, 441 00:25:43,920 --> 00:25:47,382 Earth is the only place in all of known space 442 00:25:47,423 --> 00:25:49,258 that has living things on it. 443 00:25:49,300 --> 00:25:51,052 Coincidence? 444 00:25:51,094 --> 00:25:52,345 Not at all. 445 00:25:52,387 --> 00:25:55,723 This planet of ours is biologically alive 446 00:25:55,765 --> 00:25:59,560 precisely because it is geologically alive. 447 00:25:59,602 --> 00:26:03,272 Many scientists speculate that life began in ocean vents 448 00:26:03,314 --> 00:26:06,192 fed by the churning heat of Earth's core. 449 00:26:06,234 --> 00:26:07,860 It's like those bumper stickers say, 450 00:26:07,902 --> 00:26:11,197 "Live, laugh, lava?" 451 00:26:11,239 --> 00:26:13,199 [clears throat] Funny story. 452 00:26:13,241 --> 00:26:16,035 When I was in seventh grade, my teacher, Mrs. Paul, 453 00:26:16,077 --> 00:26:20,039 told us about Alfred Wegener and continental drift. 454 00:26:20,081 --> 00:26:23,376 Wegener speculated that Africa and South America 455 00:26:23,418 --> 00:26:25,253 used to be one continent 456 00:26:25,294 --> 00:26:28,631 because they seemed to fit together like puzzle pieces. 457 00:26:28,673 --> 00:26:31,551 At first, the idea that continents could scoot around 458 00:26:31,592 --> 00:26:33,219 seemed comical. 459 00:26:33,261 --> 00:26:36,180 But just five years after I got out of high school, 460 00:26:36,222 --> 00:26:39,225 that crazy idea was established science. 461 00:26:39,267 --> 00:26:41,477 See, Mrs. Paul was right. 462 00:26:41,519 --> 00:26:44,355 I told you it was a funny story. 463 00:26:44,397 --> 00:26:47,692 In the late 1960s, geologists on research ships 464 00:26:47,734 --> 00:26:52,321 discovered that the sea floor is slowly tearing apart 465 00:26:52,363 --> 00:26:55,408 at what we now call the Mid-Atlantic Ridge, 466 00:26:55,450 --> 00:26:58,494 causing North America to drift away from Europe 467 00:26:58,536 --> 00:27:00,496 about two centimeters a year, 468 00:27:00,538 --> 00:27:02,915 about as fast as your fingernails grow. 469 00:27:02,957 --> 00:27:04,834 Might not seem like much, 470 00:27:04,876 --> 00:27:07,420 but over millions of years, it adds up. 471 00:27:07,462 --> 00:27:12,341 Just picture millions of years of fingernails growing. 472 00:27:12,383 --> 00:27:14,802 No. [clears throat] Let's--let's not do that. 473 00:27:14,844 --> 00:27:16,846 We now know that Earth's crust 474 00:27:16,888 --> 00:27:19,724 isn't just one big shell of rock. 475 00:27:19,766 --> 00:27:23,853 It's broken into a dozen major pieces and a few smaller ones, 476 00:27:23,895 --> 00:27:26,564 and all those pieces are called plates, 477 00:27:26,606 --> 00:27:29,609 each one moving in a slightly different direction. 478 00:27:29,650 --> 00:27:31,611 The whole system of moving plates 479 00:27:31,652 --> 00:27:33,571 is called tectonics, 480 00:27:33,613 --> 00:27:36,032 from the Greek word for construction. 481 00:27:36,074 --> 00:27:39,911 When the plates collide or break apart, watch out. 482 00:27:39,952 --> 00:27:42,330 Geologic pandemonium breaks loose, 483 00:27:42,371 --> 00:27:46,626 rocks and lava living together. 484 00:27:46,667 --> 00:27:50,463 While the Atlantic Ocean is expanding on one side, 485 00:27:50,505 --> 00:27:54,342 over on this side, the plates are closing in on each other 486 00:27:54,384 --> 00:27:55,635 from all directions, 487 00:27:55,676 --> 00:27:57,762 colliding with tremendous energy, 488 00:27:57,804 --> 00:28:01,349 and creating the Ring of Fire. 489 00:28:05,269 --> 00:28:08,940 On our planet, it's all about cycles. 490 00:28:08,981 --> 00:28:12,151 Heat inside the Earth drives cycles of melted rock, 491 00:28:12,193 --> 00:28:14,570 and that's why the world is so dangerous. 492 00:28:14,612 --> 00:28:17,657 And it's also why we're alive. 493 00:28:17,698 --> 00:28:19,158 Allow me to demonstrate 494 00:28:19,200 --> 00:28:22,161 while also getting some always welcome cardio. 495 00:28:22,203 --> 00:28:25,164 I'll drive the cycles of Earth. 496 00:28:25,206 --> 00:28:27,291 The inner workings of Earth are alive 497 00:28:27,333 --> 00:28:30,294 with geological and biological forces, 498 00:28:30,336 --> 00:28:33,005 all of them cycling at the same time, 499 00:28:33,047 --> 00:28:35,842 all simultaneously sustaining life 500 00:28:35,883 --> 00:28:37,844 and also destroying it. 501 00:28:37,885 --> 00:28:40,054 There's the water cycle. 502 00:28:40,096 --> 00:28:43,683 Everybody knows that life needs water. 503 00:28:43,725 --> 00:28:46,102 Nothing on Earth would live long without it, 504 00:28:46,144 --> 00:28:48,855 certainly not you and me. 505 00:28:48,896 --> 00:28:50,940 Oceans become clouds. 506 00:28:50,982 --> 00:28:52,567 Clouds become rain. 507 00:28:52,608 --> 00:28:55,111 Rain becomes rivers and lakes. 508 00:28:55,153 --> 00:29:00,074 But hurricanes, tornadoes, lightning storms, floods, 509 00:29:00,116 --> 00:29:02,785 are all part of the water cycle too. 510 00:29:02,827 --> 00:29:05,580 Some of that water seeps deep into the Earth, 511 00:29:05,621 --> 00:29:08,291 where it's filtered through rocks and minerals 512 00:29:08,332 --> 00:29:11,085 and produces the molecules needed for life. 513 00:29:11,127 --> 00:29:14,380 This is the carbon cycle. 514 00:29:14,422 --> 00:29:17,842 Life is made of carbon molecules. 515 00:29:17,884 --> 00:29:21,512 The carbon dioxide in our atmosphere feeds plants. 516 00:29:21,554 --> 00:29:24,724 Animals eat plants, including us, 517 00:29:24,766 --> 00:29:27,727 who also eat other animals. 518 00:29:27,769 --> 00:29:29,812 When plants and animals die, 519 00:29:29,854 --> 00:29:31,522 they return that carbon back 520 00:29:31,564 --> 00:29:33,066 to the Earth and air. 521 00:29:33,107 --> 00:29:35,234 It's the cycle of life, baby, 522 00:29:35,276 --> 00:29:38,821 but the carbon cycle walks a narrow tightrope. 523 00:29:38,863 --> 00:29:42,658 Too much carbon dioxide, and our planet gets too hot. 524 00:29:42,700 --> 00:29:44,660 We broil like Venus. 525 00:29:44,702 --> 00:29:47,455 Too little carbon, and our planet cools, 526 00:29:47,497 --> 00:29:49,540 and we freeze like Mars. 527 00:29:49,582 --> 00:29:51,751 Too much carbon in the atmosphere 528 00:29:51,793 --> 00:29:53,961 is driving climate change, 529 00:29:54,003 --> 00:29:57,924 the greatest disaster we face today. 530 00:29:57,965 --> 00:30:00,760 Our planet has other cycles too. 531 00:30:00,802 --> 00:30:03,012 Earth has an oxygen cycle, 532 00:30:03,054 --> 00:30:04,722 a nitrogen cycle, 533 00:30:04,764 --> 00:30:08,810 a phosphorus cycle, and, of course, a water cycle. 534 00:30:08,851 --> 00:30:11,687 [panting] These cycles run all at once. 535 00:30:11,729 --> 00:30:15,525 Nothing stays in place long on our restless Earth. 536 00:30:15,566 --> 00:30:17,527 They're all largely driven 537 00:30:17,568 --> 00:30:21,989 by powerful geologic forces inside our planet. 538 00:30:22,031 --> 00:30:24,117 When those forces are unleashed, 539 00:30:24,158 --> 00:30:27,870 you get volcanoes and earthquakes. 540 00:30:27,912 --> 00:30:29,956 It's why the Ring of Fire exists. 541 00:30:29,997 --> 00:30:31,457 It's why Mother Earth, 542 00:30:31,499 --> 00:30:33,793 in all her transformational glory, 543 00:30:33,835 --> 00:30:36,921 is beautiful but deadly, 544 00:30:36,963 --> 00:30:40,091 the femme fatale of our

still be a lot safer 644 00:35:29,839 --> 00:35:32,050 if the buildings there have deep foundations 645 00:35:32,091 --> 00:35:33,676 that connect to bedrock. 646 00:35:36,429 --> 00:35:38,806 Buildings themselves can also do a lot 647 00:35:38,848 --> 00:35:41,267 to absorb and resist the seismic waves 648 00:35:41,309 --> 00:35:44,479 an earthquake throws at them. 649 00:35:44,520 --> 00:35:47,982 Case in point, the Taipei Tower in Taiwan. 650 00:35:48,024 --> 00:35:50,026 It uses a massive pendulum 651 00:35:50,068 --> 00:35:53,488 suspended inside the building from the 91st floor 652 00:35:53,529 --> 00:35:54,822 to counter and absorb 653 00:35:54,864 --> 00:35:57,742 the swaying motion in an earthquake. 654 00:35:57,784 --> 00:36:00,286 Many of the world's tallest skyscrapers 655 00:36:00,328 --> 00:36:02,872 make use of the same counterweight idea. 656 00:36:05,541 --> 00:36:08,044 And we need to think beyond earthquakes. 657 00:36:08,086 --> 00:36:09,504 Some of the biggest threats 658 00:36:09,545 --> 00:36:13,257 from Earth's shifty tectonic plates are tsunamis. 659 00:36:13,299 --> 00:36:14,884 They may be unstoppable, 660 00:36:14,926 --> 00:36:17,345 but we can drastically reduce their impact 661 00:36:17,387 --> 00:36:20,139 with seawalls and fortified structures 662 00:36:20,181 --> 00:36:22,225 if we knew where and how a tsunami 663 00:36:22,266 --> 00:36:24,268 was most likely to strike. 664 00:36:24,310 --> 00:36:26,062 That's why tsunami simulators 665 00:36:26,104 --> 00:36:29,273 like the one in London are such a big deal. 666 00:36:29,315 --> 00:36:31,776 Engineers here run experiments 667 00:36:31,818 --> 00:36:34,779 to simulate extreme tsunami conditions. 668 00:36:34,821 --> 00:36:36,906 Their research will help us better predict 669 00:36:36,948 --> 00:36:39,325 where and how tsunamis will strike 670 00:36:39,367 --> 00:36:41,411 and better protect us against them. 671 00:36:41,452 --> 00:36:43,496 The destructive power of tsunamis 672 00:36:43,538 --> 00:36:46,040 makes them impossible to study in real life, 673 00:36:46,082 --> 00:36:49,544 so recreating them in a lab helps scientists observe 674 00:36:49,585 --> 00:36:51,254 how the huge waves form 675 00:36:51,295 --> 00:36:52,922 and how they move across the ocean 676 00:36:52,964 --> 00:36:56,843 and what happens when they hit the shore. 677 00:36:56,884 --> 00:36:58,970 Model houses and buildings show how 678 00:36:59,011 --> 00:37:01,097 different materials are impacted, 679 00:37:01,139 --> 00:37:03,725 which helps engineers build better structures 680 00:37:03,766 --> 00:37:07,645 and design seismographs, tide gauges, pressure sensors, 681 00:37:07,687 --> 00:37:10,148 and other technologies to detect tsunamis 682 00:37:10,189 --> 00:37:13,818

save the most lives. 688 00:37:27,832 --> 00:37:32,003 The most powerful safety measure we have is information. 689 00:37:32,045 --> 00:37:33,296 That's why it's so important 690 00:37:33,337 --> 00:37:35,089 that we all communicate with each other 691 00:37:35,131 --> 00:37:37,675 and don't allow politics and paranoia 692 00:37:37,717 --> 00:37:41,554 to cloud the free flow of scientific data. 693 00:37:41,596 --> 00:37:44,724 Information also has to be secure. 694 00:37:44,766 --> 00:37:46,517 We need to harden our infrastructure 695 00:37:46,559 --> 00:37:48,102 against cyberattacks, 696 00:37:48,144 --> 00:37:51,105 and we need better systems to provide early warnings, 697 00:37:51,147 --> 00:37:54,984 another low cost, high payoff investment. 698 00:37:55,026 --> 00:37:56,527 Five minutes of early warning 699 00:37:56,569 --> 00:37:58,988 makes a huge difference in a tsunami. 700 00:37:59,030 --> 00:38:01,616 And I can tell you from personal experience, 701 00:38:01,657 --> 00:38:04,535 even ten seconds can mean the difference between 702 00:38:04,577 --> 00:38:06,913 life and death in an earthquake. 703 00:38:06,954 --> 00:38:10,249 In a world with

still a lot of work to be done, 763 00:41:01,713 --> 00:41:04,090 the world is better today for more people 764 00:41:04,132 --> 00:41:06,634 than it's ever been in recorded history. 765 00:41:06,676 --> 00:41:08,219 And do you know why? 766 00:41:08,261 --> 00:41:09,470 Because we're figuring out 767 00:41:09,512 --> 00:41:12,140 how to use science for the greater good. 768 00:41:13,433 --> 00:41:15,017 Make no mistake, 769 00:41:15,059 --> 00:41:17,270 we're living at a dangerous time, 770 00:41:17,311 --> 00:41:18,771 a frightening time. 771 00:41:18,813 --> 00:41:22,817 We're facing big problems, and we need big solutions, 772 00:41:22,859 --> 00:41:25,445 but we are a resilient species 773 00:41:25,486 --> 00:41:28,656 with a unique ability to think and reason. 774 00:41:28,698 --> 00:41:31,200 So do I think the end is nigh? 775 00:41:31,242 --> 00:41:32,285 No. 776 00:41:32,326 --> 00:41:34,078 The end's a long way off 777 00:41:34,120 --> 00:41:37,373 because together, we can-- dare I say it-- 778 00:41:37,415 --> 00:41:40,251 change the world. 779 00:41:40,293 --> 00:41:43,212 [bold triumphant music] 780 00:41:43,254 --> 00:41:47,508 * * 781 00:41:49,677 -->
