1
00:00:11,640 --> 00:00:15,740
So we're now in a situation where every year is going to be seeing

2
00:00:15,740 --> 00:00:20,230
extremes that have had a contribution from that global warming

3
00:00:20,230 --> 00:00:24,940
because we're this is the 7th year in a row that the temperatures

4
00:00:24,940 --> 00:00:28,630
have been more than about two degrees Fahrenheit above the 

5
00:00:28,630 --> 00:00:31,560
late 19th century and that's enough to be having

6
00:00:31,560 --> 00:00:33,700
an effect on daily weather.

7
00:00:33,700 --> 00:00:37,380
So we're seeing things like the Pacific Northwest heat wave

8
00:00:37,380 --> 00:00:40,740
sending record temperatures across that whole region

9
00:00:40,740 --> 00:00:45,050
Or we're seeing marine heat waves. We're seeing intense rainfall.

10
00:00:45,050 --> 00:00:47,800
All of these things are coming and they're going to be

11
00:00:47,800 --> 00:00:51,860
we're seeing them every year because we are now

12
00:00:51,860 --> 00:00:54,150
in a globally warmed world.

13
00:00:54,150 --> 00:01:02,550


14
00:01:02,550 --> 00:01:06,820
So obviously nobody really lives in the global average temperature

15
00:01:06,820 --> 00:01:09,190
but what we've seen is that the changes

16
00:01:09,190 --> 00:01:14,360
in that measure are so large now that we're seeing it in

17
00:01:14,360 --> 00:01:17,150
local and regional temperature changes.

18
00:01:17,150 --> 00:01:20,480
And we're seeing it in local and temperature weather events

19
00:01:20,480 --> 00:01:25,050
And so the rainfall, when it rains, it's raining more intensely.

20
00:01:25,050 --> 00:01:26,660
We're seeing that everywhere. 

21
00:01:26,660 --> 00:01:32,750
Even at a local scale. We're seeing the strength and duration of heat waves,

22
00:01:32,750 --> 00:01:36,230
increasing everywhere even on a local scale. 

23
00:01:36,230 --> 00:01:40,550
We're seeing the impacts of that global warming temperature and the melting ice

24
00:01:40,550 --> 00:01:44,440
impacting sea level. And that's impacting coastal flooding rates

25
00:01:44,440 --> 00:01:48,170
everywhere pretty much along the coast, particularly on the East Coast,

26
00:01:48,170 --> 00:01:51,540
which is a which is a hot spot for sea level rise 

27
00:01:51,540 --> 00:01:54,890
And so the changes that we've seen are

28
00:01:54,890 --> 00:01:59,060
now large enough that we can detect them that where we are. 

29
00:01:59,060 --> 00:02:03,080
We don't need to just be looking at these kind of big aggregate

30
00:02:03,080 --> 00:02:07,540
global measures to see the changes that we have wrought.

31
00:02:07,540 --> 00:02:14,850


32
00:02:14,850 --> 00:02:21,680
Oh so Landsat is, Landsat 9, is the latest in an almost 50 year series

33
00:02:21,680 --> 00:02:25,740
of measurements starting our way back in the 1970s 

34
00:02:25,740 --> 00:02:30,990
and that gives us a unique view of the surface and the changes on the surface. 

35
00:02:30,990 --> 00:02:34,640
a lot of which are related to climate change.

36
00:02:34,640 --> 00:02:38,940
so we can use the Landsat data to go back and look at glaciers

37
00:02:38,940 --> 00:02:42,250
are retreating overtime, changes in

38
00:02:42,250 --> 00:02:49,920
stream flow, changes in lakes, changes in fire - we can see those scars

39
00:02:49,920 --> 00:02:53,060
we can see those marks, those fingerprints in the landscape

40
00:02:53,060 --> 00:02:58,150
that we can now document over those many decades 

41
00:02:58,150 --> 00:03:02,690
and so we can see, those changes. The overall

42
00:03:02,690 --> 00:03:07,260
monitoring of the climate system from satellite is absolutely essential

43
00:03:07,260 --> 00:03:12,790
for us not just to know how things are changing, but why things are changing.

44
00:03:12,790 --> 00:03:16,630
Looking at the process is looking at the clouds looking at the water vapor,

45
00:03:16,630 --> 00:03:18,680
looking at what the impacts are on ozone.

46
00:03:18,680 --> 00:03:23,880
All of those things are being looked at from space using NASA instruments 

47
00:03:23,880 --> 00:03:25,770
and our international partners, 

48
00:03:25,770 --> 00:03:31,760
and they're giving us a very, very clear picture of what's happening throughout the

49
00:03:31,760 --> 00:03:34,600
whole system. It's not just that the surface is warming.

50
00:03:34,600 --> 00:03:38,250
The changes are being seen everywhere and those changes have a

51
00:03:38,250 --> 00:03:45,520
unique fingerprint that tells us that this is basically due to our activities.

52
00:03:45,520 --> 00:03:52,620


53
00:03:52,620 --> 00:03:55,000
Well, unfortunately, it's more of the same. 

54
00:03:55,000 --> 00:03:58,200
We're going to see greater levels of sea level rise.

55
00:03:58,200 --> 00:04:00,180
We're going to see more heat waves. 

56
00:04:00,180 --> 00:04:02,100
We're going to see more intense precipitation.

57
00:04:02,100 --> 00:04:07,820
We're going to see more intense storms in tropical cyclones and hurricanes in the Atlantic. 

58
00:04:07,820 --> 00:04:12,370
We're going to see a shifts North of the storm tracks.

59
00:04:12,370 --> 00:04:16,740
We’re going to see decreases even more in the Arctic sea ice. 

60
00:04:16,740 --> 00:04:21,160
We're going to see in continued mass loss from Greenland and West Antarctica

61
00:04:21,160 --> 00:04:24,190
and so these are the things that we predicted

62
00:04:24,190 --> 00:04:29,060
would happen, you know decades ago, and and now they are happening

63
00:04:29,060 --> 00:04:31,270
and we're just anticipating that they're going to happen

64
00:04:31,270 --> 00:04:37,840
more and more rapidly, if we don't change the trajectory that the planet is on.

65
00:04:37,840 --> 00:04:39,424
