1
00:00:05,749 --> 00:00:02,950
uh yesterday's flight was intended to

2
00:00:08,150 --> 00:00:05,759
take us from the deserts of california

3
00:00:10,549 --> 00:00:08,160
to the north pole so the mission turned

4
00:00:12,629 --> 00:00:10,559
out to be quite a challenge then we had

5
00:00:14,470 --> 00:00:12,639
bad weather in the arctic and made it

6
00:00:16,310 --> 00:00:14,480
very difficult for us to do the sampling

7
00:00:18,470 --> 00:00:16,320
that we had really intended to do the

8
00:00:20,470 --> 00:00:18,480
crew was very resourceful and they were

9
00:00:21,910 --> 00:00:20,480
able to take us from the upper

10
00:00:22,870 --> 00:00:21,920
atmosphere down right down to the

11
00:00:24,630 --> 00:00:22,880
surface

12
00:00:27,429 --> 00:00:24,640
where we flew around and were able to

13
00:00:29,750 --> 00:00:27,439
observe melting of the ice and also to

14
00:00:32,150 --> 00:00:29,760
observe the changing and

15
00:00:33,430 --> 00:00:32,160
composition into the core of the arctic

16
00:00:36,870 --> 00:00:33,440
circulation

17
00:00:39,350 --> 00:00:36,880
we found the air was really really clean

18
00:00:42,630 --> 00:00:39,360
but outside of there it's been extremely

19
00:00:44,549 --> 00:00:42,640
hot and dry in alaska and in siberia and

20
00:00:46,790 --> 00:00:44,559
there's a lot of fire burning and we

21
00:00:49,990 --> 00:00:46,800
could see the output of smoke all the

22
00:00:52,869 --> 00:00:50,000
way there and we also were traveling

23
00:00:55,830 --> 00:00:52,879
into the kind of the heartland of

24
00:00:58,150 --> 00:00:55,840
climate change so the arctic is

25
00:01:00,389 --> 00:00:58,160
changing very very quickly we didn't see

26
00:01:02,549 --> 00:01:00,399
any multi-year ice all we saw were very

27
00:01:03,750 --> 00:01:02,559
very flat pieces of ice that were all

28
00:01:06,789 --> 00:01:03,760
broken up

29
00:01:08,870 --> 00:01:06,799
uh the flat pieces of first year ice we

30
00:01:10,630 --> 00:01:08,880
had done this same trip 20 years ago

31
00:01:12,950 --> 00:01:10,640
there would have been scabs of moldy or

32
00:01:14,550 --> 00:01:12,960
ice and very little open water so it was

33
00:01:19,830 --> 00:01:14,560
a very successful flight and we're

34
00:01:26,310 --> 00:01:23,270
we are here in hawaii now we're at the

35
00:01:28,390 --> 00:01:26,320
james cook memorial this is where a spot

36
00:01:30,789 --> 00:01:28,400
near where james cook was killed now

37
00:01:32,630 --> 00:01:30,799
james cook was the captain of a british

38
00:01:34,630 --> 00:01:32,640
ship exploring the world this is what

39
00:01:37,670 --> 00:01:34,640
the atom mission is doing right now we

40
00:01:39,670 --> 00:01:37,680
are flying the nasa dc8 around the world

41
00:01:41,830 --> 00:01:39,680
jumping from spot to spot uh yesterday

42
00:01:44,230 --> 00:01:41,840
on wednesday we jumped down from

43
00:01:45,910 --> 00:01:44,240
anchorage alaska down here to hawaii and

44
00:01:49,510 --> 00:01:45,920
we went past a little

45
00:01:51,670 --> 00:01:49,520
uh aleutian um airfield called cold bay

46
00:01:53,830 --> 00:01:51,680
and in fact we went down over cold bay a

47
00:01:55,749 --> 00:01:53,840
couple hundred feet so all the way down

48
00:01:58,310 --> 00:01:55,759
here to hawaii we're going up and down

49
00:02:01,590 --> 00:01:58,320
and up and down measuring atmospheric

50
00:02:03,109 --> 00:02:01,600
gases so like james cook

51
00:02:05,590 --> 00:02:03,119
we're exploring the world we're

52
00:02:07,429 --> 00:02:05,600
exploring the atmosphere to find out

53
00:02:09,190 --> 00:02:07,439
what might happen in the future from

54
00:02:12,229 --> 00:02:09,200
climate change so today we're in this

55
00:02:14,390 --> 00:02:12,239
lovely spot on saturday we fly down to

56
00:02:15,990 --> 00:02:14,400
american samoa and then it's on to
