1 00:00:00,000 --> 00:00:04,330 I can’t really name anyone that has so much integrity as she does to the things she’s accomplishing. It’s pretty amazing 2 00:00:04,330 --> 00:00:08,530 to the things she’s accomplishing. It’s pretty amazing 3 00:00:26,850 --> 00:00:30,690 Having Claire as a role model, just a strong woman in science 4 00:00:30,690 --> 00:00:36,030 and just so smart and so kind. It’s just a huge confidence booster 5 00:00:36,030 --> 00:00:41,630 it just, hey I could do that too. That’s possible, that’s successful, that’s what I want to do. 6 00:00:41,630 --> 00:00:44,430 I would characterize her as a pioneer in the field. 7 00:00:44,430 --> 00:00:49,570 The amount and quality of the work she’s put out, is second to none. 8 00:00:49,570 --> 00:00:54,150 I know people who have a lot of tenacity, I know people who have integrity. 9 00:00:54,150 --> 00:00:59,420 But it’s rare that people have both together in that combination that Claire does. 10 00:01:00,080 --> 00:01:06,320 Every morning, Dr. Claire Parkinson gets up before sunrise and runs two miles to work. 11 00:01:06,320 --> 00:01:10,340 She hasn’t missed a day in nearly forty years. 12 00:01:11,960 --> 00:01:16,510 NASA Explorers 13 00:01:19,110 --> 00:01:21,940 Cryosphere 14 00:01:21,940 --> 00:01:25,240 Ice Odyssey 15 00:01:25,240 --> 00:01:28,340 Episode Three 16 00:01:32,190 --> 00:01:37,390 To know the evolution of sea ice and how we observe it from space, is to know Claire. 17 00:01:37,390 --> 00:01:40,530 This year, she celebrating forty years at NASA. 18 00:01:40,530 --> 00:01:51,340 When I arrived at Goddard, which was in July 1978, it was an incredibly exciting period here. 19 00:01:51,340 --> 00:01:57,590 Satellites were pretty new, but a lot of data had been collected. 20 00:01:57,590 --> 00:02:03,100 NASA scientists were inundated with information and Claire was in a cohort looking at sea ice, 21 00:02:03,100 --> 00:02:07,820 trying to make sense of a jumble of very raw, very new data. 22 00:02:07,820 --> 00:02:12,330 It was around that time, that Claire and her team, at the time led by Dr. Jay Zwally 23 00:02:12,330 --> 00:02:16,530 created the principle sea ice record that we use today. 24 00:02:16,530 --> 00:02:21,130 How does something like that record help you do your job? 25 00:02:21,130 --> 00:02:26,500 Oh, that record is fundamental to understanding sea ice. 26 00:02:26,500 --> 00:02:30,640 So without it, we wouldn’t know how rapidly it's changing. 27 00:02:43,580 --> 00:02:47,450 You may not realize it, but Claire’s work studying the changing extent 28 00:02:47,450 --> 00:02:52,440 of the ice caps deeply affected our understanding of climate change and relatedly, 29 00:02:52,440 --> 00:02:56,720 our understanding of how climate change affects life on Earth. 30 00:02:58,900 --> 00:03:05,870 One of the clearest signals for climate change that resonates with people 31 00:03:05,870 --> 00:03:10,630 has been the shrinking of this polar ice cap in the summer 32 00:03:10,630 --> 00:03:14,620 that we’re able to see because of Claire’s work. 33 00:03:14,620 --> 00:03:20,620 After we had a record that was about fifteen to twenty years long, 34 00:03:20,620 --> 00:03:28,900 we started noticing that the extent of sea ice in the Arctic was getting smaller over time. 35 00:03:30,760 --> 00:03:33,530 Sea ice is formed on the surface of the ocean 36 00:03:33,530 --> 00:03:36,250 and therefore is made from sea water. 37 00:03:36,250 --> 00:03:38,610 The biggest concentration is in the Arctic. 38 00:03:38,610 --> 00:03:42,850 And it’s also where the biggest loss in sea ice is occurring. 39 00:03:42,850 --> 00:03:47,890 Every year NASA reports on the sea ice minimum and maximum extents. 40 00:03:47,890 --> 00:03:51,220 As expected, the data is concerning. 41 00:03:51,220 --> 00:03:58,030 By now, not only has this trend toward lesser ice continued, 42 00:03:58,030 --> 00:04:06,340 but it’s even accelerated so that now the decreases are greater than what they had been. 43 00:04:10,500 --> 00:04:14,350 These trends are deeply troubling, but one thing’s for sure: 44 00:04:15,260 --> 00:04:19,630 our awareness of shrinking sea ice extent due to climate change was propelled 45 00:04:19,630 --> 00:04:23,710 faster and further after Claire Parkinson arrived at NASA. 46 00:04:23,710 --> 00:04:30,170 I mean, she takes her job seriously and the health and welfare of those instruments in space. 47 00:04:30,170 --> 00:04:33,850 Yup, she’s on it. You know it’s one of the things you don’t worry about, 48 00:04:33,850 --> 00:04:37,560 because Claire’s in the loop on these things. It’s gonna be fine. 49 00:04:38,440 --> 00:04:41,570 In science, we stand on the shoulders of giants, 50 00:04:41,570 --> 00:04:45,150 on the shoulders of those who explored before us. 51 00:04:45,150 --> 00:04:51,190 But then some among us are giants. 52 00:04:54,420 --> 00:04:56,630 On the next episode of Cryosphere 53 00:04:56,630 --> 00:05:00,020 For a scientist, its incredibly exciting to be studying these 54 00:05:00,020 --> 00:05:01,590 glaciers and ice sheets right now because 55 00:05:01,590 --> 00:05:05,170 they're doing something that hasn't happened in thousands of years.
