Show us what's happening here.] 3 00:00:06,340 --> 00:00:09,380 [text on screen: This new timelapse shows 20 years of life on Earth. Show us what's happening here.] 4 00:00:09,380 --> 00:00:12,490 Well NASA has a fleet of satellites that 5 00:00:12,490 --> 00:00:15,580 are always measuring Earth or looking at land, oceans, 6 00:00:15,580 --> 00:00:18,670 atmospheres, ice altogether. 7 00:00:18,670 --> 00:00:21,850 Uh - the particular visualization you'll see next 8 00:00:21,850 --> 00:00:24,880 represents the measurement of all life on Earth 9 00:00:24,880 --> 00:00:27,920 over 20 years. I personally find 10 00:00:27,920 --> 00:00:30,980 it mesmerizing, um, you're watching the Earth 11 00:00:30,980 --> 00:00:34,050 breathe here. The seasons are changing. Ice is coming in and retreating. 12 00:00:34,050 --> 00:00:37,150 You can see the forests on land in green, expanding 13 00:00:37,150 --> 00:00:40,180 and contracting. You can see the deserts. Moving 14 00:00:40,180 --> 00:00:43,310 to the ocean you can see biological deserts in the centers 15 00:00:43,310 --> 00:00:46,460 of the ocean, represented by blues and purples. 16 00:00:46,460 --> 00:00:49,510 And then as you look farther north in the Atlantic or towards 17 00:00:49,510 --> 00:00:52,550 Antarctica you can see these greens and yellows, 18 00:00:52,550 --> 00:00:55,600 explosion of life in ocean just like on land in the spring and summer. 19 00:00:55,600 --> 00:00:58,620 Incredible. 20 00:00:58,620 --> 00:01:01,630 [text on screen: What trends has NASA observed over the last two decades of studying life on Earth?] 21 00:01:01,630 --> 00:01:04,710 Absolutely, the view from space has 22 00:01:04,710 --> 00:01:07,790 opened our eyes to so many different things. 23 00:01:07,790 --> 00:01:10,810 You can see transitions from La Nina to to El 24 00:01:10,810 --> 00:01:13,910 Nino, represented by huge blooms of 25 00:01:13,910 --> 00:01:17,000 life across the pacific ocean at the eqator. 26 00:01:17,000 --> 00:01:20,040 Bigger and wider than the United States you can see 27 00:01:20,040 --> 00:01:23,070 greening of the Arctic. 28 00:01:23,070 --> 00:01:26,110 You can see earlier summers, later winters. 29 00:01:26,110 --> 00:01:29,150 And you can see the emergence of harmful and nuisance 30 00:01:29,150 --> 00:01:32,200 algae that appear in areas and make 31 00:01:32,200 --> 00:01:35,250 a lot of work of shell fisherman and commercial fisherman. 32 00:01:35,250 --> 00:01:38,260 [text on screen: What makes this data set of life on Earth so special?] 33 00:01:38,260 --> 00:01:41,350 The ability to 34 00:01:41,350 --> 00:01:44,430 expand your senses into space, compress 35 00:01:44,430 --> 00:01:47,540 time, watch visualizations like these 36 00:01:47,540 --> 00:01:50,570 see how the ecosystems 37 00:01:50,570 --> 00:01:53,710 of land, ocean, atmosphere, ice all interact 38 00:01:53,710 --> 00:01:56,740 and then be able to rewind and watch it again and again. 39 00:01:56,740 --> 00:01:59,780 It's -yeah 40 00:01:59,780 --> 00:02:02,790 It's amazing. 41 00:02:02,790 --> 00:02:05,830 [text on screen: Where can we go to learn more?] 42 00:02:05,830 --> 00:02:08,860 Please visit us online at nasa.gov/earth 43 00:02:08,860 --> 00:02:11,900 you can see all of our visualizations there. 44 00:02:11,900 --> 00:02:14,950 You can see stories about this. If you're really 45 00:02:14,950 --> 00:02:17,980 keen on getting the data you can do so too, with tools how to use it. 46 00:02:17,980 --> 00:02:20,407 And then, on Twitter @NASAEarth.
