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

00:00:08,530 --> 00:00:26,850

4

00:00:26,850 --> 00:00:30,690

Having Claire as a role model, just a strong woman in science

5

00:00:30,690 --> 00:00:36,030

and just so smart and so kind. It’s just a huge confidence booster

6

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.

7

00:00:41,630 --> 00:00:44,430

I would characterize her as a pioneer in the field.

8

00:00:44,430 --> 00:00:49,570

The amount and quality of the work she’s put out, is second to none.

9

00:00:49,570 --> 00:00:54,150

I know people who have a lot of tenacity, I know people who have integrity.

10

00:00:54,150 --> 00:00:59,420

But it’s rare that people have both together in that combination that Claire does.

11

00:00:59,420 --> 00:01:00,080

12

00:01:00,080 --> 00:01:06,320

Every morning, Dr. Claire Parkinson gets up before sunrise and runs two miles to work.

13

00:01:06,320 --> 00:01:10,340

She hasn’t missed a day in nearly forty years.

14

00:01:10,340 --> 00:01:11,960

15

00:01:11,960 --> 00:01:16,510

NASA Explorers

16

00:01:16,510 --> 00:01:19,110

Ice Odyssey

19

00:01:25,240 --> 00:01:28,340

Episode Three

20

00:01:28,340 --> 00:01:32,190

21

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.

22

00:01:37,390 --> 00:01:40,530

This year, she celebrating forty years at NASA.

23

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.

24

00:01:51,340 --> 00:01:57,590

Satellites were pretty new, but a lot of data had been collected.

25

00:01:57,590 --> 00:02:03,100

NASA scientists were inundated with information and Claire was in a cohort looking at sea ice,

26

00:02:03,100 --> 00:02:07,820

trying to make sense of a jumble of very raw, very new data.

27

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

28

00:02:12,330 --> 00:02:16,530

created the principle sea ice record that we use today.

29

00:02:16,530 --> 00:02:21,130

How does something like that record help you do your job?

30

00:02:21,130 --> 00:02:26,500

Oh, that record is fundamental to understanding sea ice.

31

00:02:26,500 --> 00:02:30,640

So without it, we wouldn’t know how rapidly it's changing.

32

00:02:30,640 --> 00:02:43,580

33

00:02:43,580 --> 00:02:47,450

You may not realize it, but Claire’s work studying the changing extent

34

00:02:47,450 --> 00:02:52,440

of the ice caps deeply affected our understanding of climate change and relatedly,

35

00:02:52,440 --> 00:02:56,720

our understanding of how climate change affects life on Earth.

36

00:02:56,720 --> 00:02:58,900

37

00:02:58,900 --> 00:03:05,870

One of the clearest signals for climate change that resonates with people

38

00:03:05,870 --> 00:03:10,630

has been the shrinking of this polar ice cap in the summer

39

00:03:10,630 --> 00:03:14,620

that we’re able to see because of Claire’s work.

40

00:03:14,620 --> 00:03:20,620

After we had a record that was about fifteen to twenty years long,

41

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.

42

00:03:28,900 --> 00:03:30,760

43

00:03:30,760 --> 00:03:33,530

Sea ice is formed on the surface of the ocean

44

00:03:33,530 --> 00:03:36,250

and therefore is made from sea water.

45

00:03:36,250 --> 00:03:38,610

The biggest concentration is in the Arctic.

46

00:03:38,610 --> 00:03:42,850

And it’s also where the biggest loss in sea ice is occurring.

47

00:03:42,850 --> 00:03:47,890

Every year NASA reports on the sea ice minimum and maximum extents.

48

00:03:47,890 --> 00:03:51,220

As expected, the data is concerning.

49

00:03:51,220 --> 00:03:58,030

By now, not only has this trend toward lesser ice continued,

50

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.

51

00:04:06,340 --> 00:04:10,500

52

00:04:10,500 --> 00:04:14,350

These trends are deeply troubling, but one thing’s for sure:

53

00:04:14,350 --> 00:04:15,260

54

00:04:15,260 --> 00:04:19,630

our awareness of shrinking sea ice extent due to climate change was propelled

55

00:04:19,630 --> 00:04:23,710

faster and further after Claire Parkinson arrived at NASA.

56

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.

57

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,

58

00:04:33,850 --> 00:04:37,560

because Claire’s in the loop on these things. It’s gonna be fine.

59

00:04:37,560 --> 00:04:38,440

60

00:04:38,440 --> 00:04:41,570

In science, we stand on the shoulders of giants,

61

00:04:41,570 --> 00:04:45,150

on the shoulders of those who explored before us.

62

00:04:45,150 --> 00:04:51,190

But then some among us are giants.

63

00:04:51,190 --> 00:04:54,420

64

00:04:54,420 --> 00:04:56,630

On the next episode of Cryosphere

65

00:04:56,630 --> 00:05:00,020

For a scientist, its incredibly exciting to be studying these

66

00:05:00,020 --> 00:05:01,590

glaciers and ice sheets right now because

67

00:05:01,590 --> 00:05:05,170

they're doing something that hasn't happened in thousands of years.

68

00:05:05,170 --> 00:05:11,380

We're watching changes take place that haven't happened since the end of last ice age.

69

00:05:11,380 --> 00:05:14,800

Episode Four: Glaciers and Ice Sheets

00:05:14,800 --> 00:05:16,950
